TEAM TALK: OUTBOARD ECU FLASHING (WORTH IT??) 

I flashed my Yamaha 2023 250 SHO and gained 4+ MPH, which also improved my MPG. Thank you, Hydro Tec!

The reason flashing isn't a thing, or as popular with Mercury, is because it requires other physical mods. The Yamaha 200-250hp SHO is truly a detuned 335hp motor, no mods required to get it there other than the flash itself.

600 for my 200 sho flashed to 332 not a problem after it. Hydrotec is the best in the business!

It’s crazy. I fish against a guy that has a phoenix 819 with a 200hp sho and he flashed it and it runs 85 mph in a 19’ boat. Nuts.

I used Hydrotec when I flashed my new SHO 200. If you send the ECU to them, it's only $700. On a 2000 Stratos 20SS I gained about 10 mph over the 200 setup exactly the same. Now running 77-78 mph, and needing more setup time to hit 80

I used to feel that way too about a life vest, but then I realized it's not about my ability to control the boat as that it's about my ability to stay conscious, and awake to do so. I had a friend of the family have a heart attack while driving a bass boat and the only thing that saved his life was a vest and kill switch. I've heard of a few other instances of people passing out due to other health related issues from heat stroke/exhaustion, dehydration, etc. There has also been an instant where a guy couldn't see due to the evening sun shining directly in the eyes and got too close to some downed tree branches and is no longer here. Things happen way outside of one's control too much for me to always wear a life vest when in a moving boat.

yamaha is the king of flashing had a 250 sho 2011 flashed lasted over 600 hours till i sold it and still going strong as far as i know.

Nizpro flashed a 2018 Yamaha 250 SHO. Changed the prop to a Mercury Enertia 19. Night and day performance. Only issue is, it wiped out all of the previous ecm history. No technical data. So far so good on reliability.

Love to hear who is doing the suzuki flashing. 115ss could always use an extra pep!

2018 basscat caracal 225SHO nizpro 332hp Before flash: 70mph After flash: 78mph with limiter stock Haven't even played with props yet.

Nizpro flash you can get installed for $650-750. The supercharger kit you can get installed for 11K. Yamaha does not void warranty for Nizpro flash. Unless you install the 7100 RPM tune. Keep up the great videos Andy!

Lundins Marin here in Sweden upgrades/flashes Mercury engines. Both old and new. They have been doing it for a very long time. The work on all the major brands

I had my 75 hp Merc 4 stroke flashed by Simmons motor sports back when they could still do them. Mercury slapped their hands, and they no longer do it. Made a huge difference on my Crestliner VT17 tin boat. Turned a 38mph tin turd into a 50mph ride. Had to go up two inches of prop pitch.

I started watching this channel when i was looking at getting a new outboard. went with susuki df50. Wish he told us about the Suzuki tune company!....big fan.

I’ve been waiting for this talk! Excited to watch this one, I been watching lots of videos on the nizpo 332hp tunes for the svho. Cuz we know the 4.2 Yamaha 200/225/250/300 are the same engine.

Would like to see a link for Suzuki :)

A couple weeks ago I had the pleasure of speaking with MOM. GREAT LADY!

Ooooh I'm doing that when I get my new tritoon flashing the 250sho!

Where's the Suzuki info? I have a 115 that I would like to have flashed to at least a 140 since according to the speca they are the same engines, love your channel.

I really want to hear about the Suzuki flashing. It doesn’t have to be a personal endorsement of the product. I’ll research and take my chances. Thanks!

I would love to see some merch with Team Marine and Suzuki on it if that’s possible! I bought my first Suzuki outboard in 2021 and was unsure of it because I didn’t know much about them at the time and that’s when I found your videos and realized they are quality outboards from your videos which Reassured me I bought a good outboard. Keep up the good work Team Marine!

NIZPRO flashed my Yamaha F300 on my 2021 Cobia 240 DC, did it for hole shot and mid-range cruise performance (heavier boat 6,000 lbs). Got exactly what I hoped for mid range performance through channel navigation at 25 - 30 MPH requires way less throttle adjustments and my cruise fuel economy went from 2.6 MPG to 3.4 MPG! Also gained about 300 RPM on top end which allowed me to add more cup to the prop🤩. MPG alone makes this worth it as my average trip into the Gulf is 55 miles. Ideally I would be happier with the new 4.3 F350 but my boat is rated for 300 so this $900 Flash is way cheaper than buying the same boat rated for 350 HP.

Love, Understand ,& fully support your comments on the alleged "SAFETY LESSONS". We ain't watching your videos because we need to be INFLUENCED. 👍

Are right there with you with the back and ringing in the ears. I’m a a/c mechanic for 40 years I get it

Hey there. Just wanna tell that Lundins marine in Sweden, just did a flash of my Mercury Optimax from 75-115 Hp. Also know he does other brands and other tunes. So here is a good resource to flash Mercury.

You can't flash a Merc because they threatened to sue any company who offers a flash. This information is publicly available, Simons and Whipple used to do it. Yamaha doesn't care, they have more things going on. On a 4 stroke, especially with variable cam timing and throttle by wire, flashing makes a lot of sense. This stuff is really common in the power sports market, there is a lot to get out of these motors. The company in the US that does ECU flashes for Yamaha outboards has a long history of success, not going to mention them here, do a search.

I want to see a Allison running that outlaw kit 🔥

My sons race yamaha dirt bikes and they re-map their ecu with the yamaha power tuner and now the newest bikes are ble to be mapped via smartphone,very trick and one of the reasons we have been on yamaha bikes since they were just little guys racing in the mini class.

I love the honesty!!! Just found this video and am very interested in flashing a Suzuki. I have a 115 hp on Vexus AVX189. At some point, (when you can) give me some guidance on flashing this motor. Thanks for what you do!

I was shocked you picked the 200 merc, wondering why you didn't pick a yamaha. Then for the 225 you didn't pick a mercury which I thought was basically the same as the 200? I want a 818 but I wouldn't think a 150 would be enough if you had a full tank, livewell, 10ft power poles and co angler.

Are you sure Hydrotec flash doesn’t void Yamaha warranty? According to my dealer sny flash voids the warranty.

I want to flash the SHO 150 on my Vexus AVX1980. I swear that boat is severely underpowered with a 150. 52 mph top speed with a tournament load and two people.

Hydro tech did mine didn't move the rev limiter seen 2 to 3 mph top speed but hole shot and md range is unbelievable improvement

150 sho flashed with a nizpro marine. 1000$ canadian. Worth it in my opinion.

Hey I get the Lifejacket thing I am 63 and about 5 years ago Duck hunting Running in the Dark I wear one today but in the day light I don’t either.

hey from NZ, I'd be keen on one of those t shirts with a lifejacket printed on it. I'd buy for sure. Too funny. Our maritime law is life jacket is mandatory for boats under 6m. My boat is a 6.5m so i don't have to wear it anyway, but it'll be funny to wear the shirt on the boat.

Who is doing the suzuki tunes? Please

Now don't laugh, but would it be worth flashing a 2009 Yamaha 60 four stroke? Boat is rated at 90, but only have 60 on it. would love to possibly get to 90 horse on my tin rig for the 700 bucks everyone is saying it costs.

Flashing the Evinrude just helps it to the scrap bin faster…

Think you should do a video on 2 degree and 5 degree wedges one of the most common questions we ge. Be nice refer our customers to your video.

You need to put the Team Marine skull and cross wrench ( red outline like the long sleeve T) on a trucker cap! Enjoy your channel

The 76hp for a suzuki df50a seem tempting

Cool content and videos! Keep them coming!

What about Outboard EFI? How you feel about them?

Honestly good to hear theres no good way to flash a merc. my transom is only rated for 115 and ive sorta been itching to look into it. Nice to remove the temptation

Need to add “No Lifejacket..” to the company slogan. Haha Should always wear kill switch though.

The hatred of Evinrude is real and completely unnecessary. There is a guy who has who rebuilt Evinrude Etec 250 with velocity stacks and all new forged internals he also got someone to deconstruct the Etec codes and flash It. It now revs to 7000 RPM. I've seen video of the boat The motor is a short shaft with a sport-master gear case. 20ft boat goes 100 MPH + YAMAHA will come after Mercury with a vengence. Mercury has had the Hi-Po limelight for far too long and they are about to have their a$$ handed to them.

Honda needs a tune the most. Surely somebody can squeeze some power out of that block.

Mercury encrypted their PCM on the new V models . It’s a reflash they have us do on the early engines .

You mentioned the Suzuki, I just bought a 200 and still haven't got the speed out of it my old HPDI did when it was new. The Yamaha 200 would push my Skeeter ZX202 around 67-68 and the Suzuki won't get me to 63. Do you think this "flashing will do the trick? I'd like to see that magic # of 70.

I've watched some nizpro videos and they are pretty crazy. I mean to put 4 or 500 horsepower on a bass boat is crazy. Man that's fast if u wanna go 110 plus lol I wonder what the record is for a bass boat. I think it's like 115-120 mph

When is the Nitro plant visit?

What effect does flashing have on the stern of the boat itself? Meaning I have 2006 ranger that is rated for a 225 max engine size. If I flashed the engine to more horsepower will it cause cracking or damage to stern of boat. Not that I think I can flash a hpdi. If I can flash the engine what would be the difference if I went. And just put a new 250 on the boat. Can the bass boats handle it or is that rated for engine max size taken loosely. Great video keep up the great work you do.

People that want to flash a Merc will end up with a product like in motorcycles called a Power Commander. It goes into the harness down stream of the ECM and can modify what is being sent to the engine.

I like the idea of the life jacket tea shirt I would buy one

Can’t flash a mercury cause the lower unit wouldn’t last a day!

Hey Andy love your videos especially the shop videos and more technical videos I love to learn 👍. But I do have a question about 2 years ago I done the donate money on your website for you to answer a technical question I had on a mercury. And I never got a reply back to my emails I’m not mad about it I’m just curious if something happened and that’s the reason I never heard back from you or anyone on your team. Keep up the good work and let’s get some mercury modifying videos 😁

I flashed my G1 ETEC from factory 150 to factory 175. I cannot afford the ProXS 200HP repower yet.

T-shirt with a life jacket printed on it I like I will buy one

How much would ya gain on a 115 SHO 4 stroke????

Is the flash offered on a Yamaha VF150 vmax sho

I was told yall are gonna start flashing the evinrude fichts! Nice!!!

Stg. 2 hyrdotec kit on yamaha pro-v 150 came to a 235 at the prop.

I used hydrotec on my 150 pro V and they rejected and I got there hi flow heads! Turned my 150 in to a 220hp

Hey, could I get a link or some info for a company to flash my 2024 200hp Suzuki? Thanks!!

Can I just purchase a used 90hp Merc ECM and remove the restrictor plate in my 75hp and it’s that easy?? No immobilizer or code needed is that what I heard?

Would love to know who to use for Suzuki I have a 60 hp boats rated for a 90. I need help getting out of the hole and on pad. Can’t find much on the used market for 90s

will flashing a yamaha 250 sho get you better fuel mpg . along with the the speed ?

Great info but the music in the background blows. My 2 cents worth

There a company in Australia that have a flash for the 4 stroke mercs

It's not available on Mercury yet because no one has cracked the ECU yet. Just like the auto manufacturers, they lock their ECU's down. That doesn't stop people from cracking that encryption and tuning them. That being said, most people that own boats just want them to be reliable. And definitely don't want to go messing with things while they are under warranty. And the cost of going from a 250 Pro XS to a 300R isn't that much money. I imagine once there are a lot more of these newer Merc's out of warranty we might see more interest in tuning.

USP marine for mercury

Ok you’re forgiven … tournament wearing yes. Don’t want you hurt either. It’s all good.

I get flashing for more speed. However: The dollars per smile to me isn't worth the cost of outboard replacement if you scatter one.

What about a tohatsu 50 any flash tunes for those ?

Hard to swim when you're knocked unconscious. Good luck

Any flashing available for an older 2004johnson 140 4stroke? If so any idea what gains look like

Is there a flash tune for yamaha f70

Hydrotec are thieves. I rejected an additional rebuild. Went to pick up my boat and when I got home I discovered they kept all my internal motor parts. When I called to ask where it was. Their response was. “We didn’t think you wanted those”. Only one piston was bad out of 6. And the crank was in great condition. Buyer beware.

Why do you want a bass boat to go that fast. I did it to my motorcycle because I drag race it. But I don’t know why I would do it to my boat.

Mercury definitely have flashes, you can flash a 350hp to a 480hp

So John, Clive and Andrew all have a 250 SHO and all have the same tune ? How can 1 tune work on all motors ? We always got told no 2 motors are the same ?

Anyone have experience with outboardefi flashes? Looking into flashing a Suzuki DF25A

A tuner in Darwin Australia has just cracked the Mercury ecu They are currently testing tunes on most models

I loved my zx200 Flashed it when I had 52hrs on it no issues

Has anyone used OutboardEFI?? WI/MN company. Looking to flash my DF70

Is Amsoil hp marine okay to run in a 2009 200 hp optimax? Have you heard anything about the mercury and quicksilver dfi oil gelling?

Small Tohatsu???

I want a Team Marine branded... "Dont wear your lifejacket or kill switch if your a badass like me" T Shirt!

Why does mercury not allow flashing of out of warranty motors?

Yamaha is the flash king, you forgot the 625 hp kit

Let's Go Andy

This question if you add horsepower to your motor reality motor aren't you going over the rated horsepower for that boat

I would have you work on my boat

Am sorry I need to ask what is flashing ??

At least wear a kill switch. I didn’t really hear a good reason not to.

Flash an Evinrude? 😂😅😂😅 Evinrude's got enough EMM problems, lol. If it's running consider yourself a lottery winner already.

Your old and experienced.. at a certain age safety is second or 18th.. lol

👍

Don't talk shit about evinrude ;) , great motor my G2 150, and about flashing, i will tune it up to 200 after warrenty :). ,Runs like a dream, like every e-tec when they run :) , 225h on it now, wonderful sound and tourqe
