This 9.9 hp Outboard Motor Is A Game Changer! 

That’s pretty cool!

I have a 21 foot cat running 2 electric motors and it is a beautiful cruising vehicle that sips electricity. I have never had a gas boat and kinda think I never will

Funny you mention about the 'old outboard cases and converting them to electric' - the summer has just begun!

The Whaler has a whole summer of work to do on the water!

Awesome!

Glad you enjoyed it!

Nice!

He is!

Yeah it's not just a 'little bit' more money - it's a lot!

They are cool boats!

it is!

It's a very fun easy and peaceful boat to use.

Yeah that would be neat to see!

I did not go into the actual cost of Dan's setup but I think it's about $1,600 to set up a third party battery system that would do the job.

Wayne did a great job outlining the pros and cons. One nice thing about this motor is that you can use any batteries you want from old lead acid to LifePo4 batteries. As noted these three batteries were bought on Amazon and over the course of a few months while I was remodeling the boat. The current price for these batteries from Eco-Worthy is $512 each. They are also in a flatter rack format and can be tucked away much more easily than the set I have. So far these have been excellent batteries. Thanks for your question and comments!

A delay between forward and reverse - I hadn't really thought much about that before, but it's a valid point for some situations.

@@WayneTheBoatGuy Yeah, there’s no noise, so it’s hard for me to tell what it’s doing, on a gas motor it’s obvious . Like I said before, I’m sure if I spent more time with it I would get better. I personally perfer the range and functionality of my Yamaha gas. I’m considering selling the epropulsion.

Yeah they aren't cheap

No need to swap that out! You're good to go.

Hey there! You are correct.

Batteries are already coming down in price - which is a good sign!

My setup cost $800aud, just gotta search

@@Lana_Warwick that's awesome!

I've a 21 foot re-purposed sailboat I've added 1600 watts of solar to. A very educated guess to the weight is 1200 lbs. Currently it has a pair of 100 amp hour lithium batteries and a pair of Minn Kota 55 lbs thrust 12 volt trolling motors - the panels keep the batteries topped off and the boat will do 4.2 mph. I'm thinking of repowering - I'm looking at the Elco 5 hp - 24 volt I like that the motor is above the water so some little leak in a seal does not flood the whole show 'keep on boatin' 😎

@@garygerard4290 Check out Striker TR100 24v, 1152W, 48A, 90lbs, 3 blade. I got for $369aud (~$245usd). Hooked it up to a '24V 100Ah LiFePO4' from alie xpress for $450aud.

Thanks!

~$16Kusd. 2 pushing don't = 2 x thrust, there's losses

I will try to get my hands on one sometime!

I just checked again and this motor is $3,599 - are you outside the US?

An old runner that is reliable is a no-brainer! Paid for, inexpensive to operate, and if we're a little bit handy, can keep going for a looong time! One of the challenges with many of the DIY electric setups is keeping things cool and keeping out the water and salt.

Yeah I agree, it would be neat to fit both rigs to the same boat and compare.

The biggest difference is the completely different way an electric outboard delivers its power. You can compare it quite well with electric vs ice cars. When fitted with similar hp-numbers, the electric car would still have the benefit of instant torque over the entire rev-range. And as we all know with boating, torque is king, so in reality you cannot compare these figures as if they were both apples… I came from a 20hp 4st. Suzuki and now also have the ePropulsion EVO 6.0 as shown in the video. I could not be happier with the downgrade in power but at the same time VERY large increase in comfort and pleasure…

It will be interesting to see how these hold up over time.

Thank you!

It depends on where you plan on boating (the waves/currents etc), how fast you want to go, the weight you plan to carry and what you will be doing. I wouldn't suggest to take a 15 foot boat out on a rough river or open water (although people do).

Thank you i will think wich boat to choase

You only need to top it off if the oil is low (like a car engine) compared to always mixing oil with the fuel on a 2 stroke.

Both of those things are improving every day. Dan is recharging his now completely via solar, and the batteries are regularly getting better, cheaper, smaller, & lighter. There are also newer battery technologies that are using less precious metals (or none at all) and other improvements happening slowly but surely.

There's already way cheaper options because they come direct from manufacture, China, like these do, so no in between mark up, expensive marketing, sales staff, etc. Just gotta search

No thanks.

It is going back to it's owner.

There are certainly trade offs - but in day to day operation, there's basically zero 'operator pollution' running an electric. The rest of it (refining, mining, disposal etc) could be debated for decades.

@@WayneTheBoatGuy I'm more concerned about if tge boat sinks.

Yeah the cost takes it out of consideration for many people.

"What do you do when it's time to refuel?" - you never have to refuel! Dan has put together a solar charger so he never needs to refuel. People don't pull skiers with a 9.9 hp - this isn't a 50 hp The reality is that if you're going out for so long and so far that you need more than your 6 gallon tank, then yeah, you wouldn't go this route. But many boaters only go out for a few hours and this system is fine for those situations.

Yeah it certainly isn't a low up-front cost

no - more like 50-100 lbs.which might be similar to a 6 gallon fuel tank and starting battery weight

I just fixed it - thanks!! www.youtube.com/@drez20001

That's why many people go another route for batteries.

Totally agree! Hence the DIY battery set up. Lead acid batteries can also be used with this motor.

Do they sell/make an outboard boat motor - or just electric motor units?

Maytech engines are cool, but they are just the electric motor part that would require a housing, shaft, reduction gearing or hub build, controller, etc. A true DIY component. A higher voltage motor would also require a very custom battery build. Voltage under 50v +/- is considered low voltage. You can touch both terminals and be okay. Over that mark it gets more real and more precautions are required for safety.

@drez20001 the motors come with the ESC (controller) bundled if needed. And up to 400 amps. Another motor I was just looking at has like 32v to 117v. With those parameters you can pretty much hook it up to whatever battery setup you'd like. A series of 8 eco-worthies at 12 volts for a 100Ah will run 117v. You figure you've got a 117 volts running at only 20 amps. That's 2,340 Watts and can run 5 hours nonstop at 20amps (hypothetically). That's maybe $1,100 for the batteries. 700 for motor and controller. Throw in an extra $200 for the wiring and miscellaneous. That's only 2k for everything, 800Ah is roughly 11670 Watt hours. Comcareable The Elco 20hp ep electric motor is $5,450.00. And ANOTHER $5,900 for their 200Ah Lithium ie. 300% less battery. Also 400,000,000 volts would do nothing to you. Volts don't hurt people. The heart depolarizes between 20mA and 120mA.. About 50mA just 0.05amps if i recall, is what it takes to cause an arrhythmia triggering a possible myocardial infraction.

@@WayneTheBoatGuy is very DIY. But they sell everything needed. There's a guy on here that built a kayak with one and the boat was planning on flat water.

There are smaller battery setups than what Dan has built.

Run time is based on battery bank size in general, as to how long and hard you can push this motor regarding heat build up, I've run it around 5,000 to 5,500 watts solid for a long time with no issues. The 2024 Navy 6 has a closed cooling system, so no impeller. The actual motor is in the hub under the water connected directly to the prop to help with cooling as well.

Sure. If yer in a 24hr boat race this may be a concern. For some boaters a few hours a day worth of go is all they need. Getting that few hours virtually silent with no fuss, pretty cool if you ask me. You could easily spec a big enough battery for most lake use I suspect but obviously you're going to be able to point out that you always motor 8 hours out and back at full throttle. Don't buy one. A jet ski can't do what a cruise ship can either.

That's cool - what size boat?

@@WayneTheBoatGuy 16.5 foot jon boat

This is a faster motor than a trolling motor.

People also spend $100,000 on brand new trucks when there's plenty of $2,000 old trucks for sale. I never said this was the solution for everyone!

It's not 10x the space and weight. The boat is 800 lbs. The motor and batteries are about 30-60 lbs more depending on the configuration and space is similar if you use a single battery pack. It's not for everyone.

That seems to be happening quite often these days.

How much do those batteries weigh?

Yes it is.

I completely understand!

That's like me saying I bought a guitar for 2k and it will last me longer than your Sea Ray. And how do you know this motor wont last for years?

I think we could find MUCH bigger ways to waste money in the boat world!

@@WayneTheBoatGuy I know lol, just being contrary! These prices just seem prohibitively expensive!

This is the same argument against electric cars. Yes, your 1979 55 hp Yamaha 2 stroke was cheaper and it will probably run for 25 more years. But we can't compare a 45 year old 55 hp to a new 9.9 - that's like comparing a 60 year old tractor to a new golf cart. They are different and serve different purposes. Not everyone wants to drive a tractor and nobody is forcing you to switch to a golf cart. To your other points: Yes we all know that a gas outboard can be refueled faster than an electric can be recharged. But most recreational boaters are out for a few hours at a time and not running at full speed the whole time and these do just fine in those situations. I take my 3 hp electrics out and am ready to come home long before the motor and battery is spent. And instead of buying gas (making sure it's ethanol free which isn't easy around me), and mixing 2 stroke oil - with this, you just plug it in while you sleep or have lunch and it only takes a couple hours not 24. "already slow because of the weight" When Dan mentioned the weight of 800 lbs, he was talking about his boat. This outboard if paired with the ePropulsion battery weighs about 30 lbs more than a similar 4 stroke gas outboard with a small fuel tank and starting battery. Dan just built a different setup because he wanted to. Yes, these are not very well suited for people who boat long distances or are out running full throttle all day unless they want to spend even MORE $ on another big battery. I feel that I covered that in the video. You service your outboard for 10 minutes in the winter and 10 in the summer. So we agree that a gasoline one requires service and this electric one doesn't. And congrats on the 10 minute impeller change and lower unit oil change - it always seems to take me longer, but I tend to putter around when I am doing that stuff. Yes, this outboard on this boat isn't going to get it on plane. It's (at most) a 9.9 on an 800 lb boat. If $5,500 is a second mortgage then also this setup isn't for you. But there's plenty of people dropping big bucks on all kinds of boat stuff (the Sea Doo Switch is $23,000 and sells well) and lots of people who don't want to mix fuel or deal with mechanical stuff. I never implied that this was an ideal replacement for boaters on a budget who aren't looking to spend a bunch of money on new stuff. I have built my own trailer guides because I'm so cheap. And with regards to sweating bullets. I spent last summer fighting my failing 2 stroke which would leave me stranded on the water and I never had an issue with any of my electrics. When my charge was getting low, I headed home just like I would do when my fuel was getting low in my gas motor (provided it was still working). And every time my voltage was low, I was ready to head home anyway! My personal experience has been that every on-the-water failure I have experienced has always been a gasoline (or diesel) engine. These are too new to speculate if they'll last 25 years, but I have an old Minn Kota still going strong - so maybe!

Yeah many people point out how the all electric outboard "hp equivalent" ratings seem high or optimistic. Digging in is kinda murky (watts versus horsepower, thrust etc) - but it does seem that the top speed of gas outboards is often higher than supposedly similar electric outboards. My 3 hp equivalent electrics don't have the same top speed as my 2.5 hp 2 stroke.

@@WayneTheBoatGuy On the positive side, they hav put efforts to make the small motor to produce as much thrust as possible, they still work OK on displacement speeds considering power output. On the other hand, if producers of small gasoline outboards had also put much more input on propellers and particularly sound proofing, you could hav an even better motor and at eco speed doin probably 3 hours with one liter of gasoline at decent sound levels....

I can't argue with that!

If you just said you would rather stick with your 2 strokes because you are comfortable with them and they are cheaper, I would have agreed with you and liked your comment. But instead you chose to call me smug and say the motor costs $10,000 when I literally show the total cost of $5,500.

My logo image is from 2019 0r 2020 - it is water and yellow sunshine. And why would you care? If your logo was red white and blue should I assume you're French? Or maybe North Korean, Russian or British - ALL countries who also are red white and blue. Please don't read politics into everything.

@@WayneTheBoatGuy Fair enough I will let you off this time with a bit of advice that people have had enough of seeing that blue and yellow crap ok champ

@billywatts4689 - you have just reminded me why I should not change my logo when you said: "people have had enough of seeing that blue and yellow crap ok champ" This is a boating channel, posting boating content. I try very hard to keep politics and the related anger from any of my content - even when touching on topics that seem to anger people for some weird reason (like electric outboard motors). When the war in Ukraine started I suddenly became the target of backlash because of my RU-vid logo. At the time I considered changing my logo. People were typing long political comments on my boating videos because of the colors of my logo which existed well before I had any idea what Ukraine's flag looked like. Angry people making opinions about me - because I happen to have a yellow blue logo (BTW the Ukraine flag is actually blue on top). I had done NOTHING wrong just like my neighbor from India who did nothing wrong and was attacked after 9-11 for "looking like a muslim". Later I received political comments over a red trucker hat I would wear that said 'Wayne The Boat Guy' that looked a lot like a MAGA hat. It became an issue when Trump announced he was running in 2024. I was concerned the hat might be perceived differently by different groups (some might think it was a protest, others might think it is subtle support) so this time I actually stopped wearing the hat and made a video announcing why I was stopping wearing the hat and guess what? That made several other people angry and many unsubscribed because they assumed I didn't support the candidate they support. I had to take the video down because the arguments and anger were out of control. All of this on a boating channel! But WHY should yellow and blue matter? Do we discard information or the review of a product because the reviewer is a different religion, color, or might be a supporter of Ukraine? Maybe we should all divide up into tribes so all of the people of one specific narrow point of view can all drive the exact same vehicle and wear the exact same jeans and tell everyone else they are wrong. Each tribe would have to agree 100% with the other members on every topic all of the time - because there's no room for a different point of view. Are we really that divided? What the heck to happened to America?

@@WayneTheBoatGuy Jesus Christ Bucky I'm not reading all that bollocks I got your point the first time!

When was the last time you had your eyes checked?
