What's the Deal with Outboard Jet Engines? 

You need one

damn it , i want one now

Alvin, great info. I have an outboard I picked up at auction I might see if that place in Cali makes one for. I'm not really trying to get up on plane. Heck, I not even trying to go fast. I'm building a tiny pontoon overnighter out of cardboard, 2 part boat foam and fiberglass. Just something lightweight I can load in the back of the pickup and assemble near the ramp and launch. I don't really want much on it in terms of structure. I've found an inflatable tent that I want to use for camping on the water. I do want to make a shade awning and have some chair mounts that can click in/out of place for different configurations, a place to cook and a dometic cooler style refrigerator or just take a cooler....I dunno still thinking about that one but it'll have a solar panel on the awning for fridge, cook plate, tunes, fish finder and phone. I just don't need anything over 5-10 hp. I'm seeing some 6.5 HP outboard jets out of South America but the shipping is just as much as the motor. Do you know of any place that sells just the down shaft and lower unit so I can just go buy a lawn mower engine from harbor freight? That would be awesome. I called Texas Parks and Wildlife to ask them what would be the procedure for titles for a combination boat/trailer, as in the boat and trailer are one. I just originally wanted to make a boat with retractable wheels. After being shuffled around to different offices they have no clue how to make that happen. They don't seem to understand why someone would want to do that. I guess convenient isn't in their vocabulary. Neither is cost effectiveness. Minus the motor I could've built that boat for the price of the trailer alone....but noooo.....guvment....ugh. Any thoughts? P.S. this is a guy, I'm using my wife's account. Mine was deleted for loving the constitution too much. Cheers, Brian

How about dude on his wife’s account? Sounds like him and his cardboard/fiberglass boat needs a channel himself. Shit bud I’ll subscribe to it

They can help get you to places others can't reach.

Glad it was helpful!

In the pacific northwest they're very common with all the shallow rapids in our rivers. Unless you run in skinny water situations they're a waste.

I appreciate that

Yeah I love mine.

Thanks for watching.

Yes you are!

Thanks for the sub!

Not yet!

Glad to help

Glad you liked it

A lot of people haven't. They are pretty cool.

Thanks for watching

No need in deep water, but If you want to run some shallow rocky stuff they are awesome.

I have run the Current River a couple of times. Bought a few motors from Fred over at Current River Marine. Beautiful water!

@@AlvinDedeauxFlyFishing Happy to share the river with ya Alvin. Always a blast going after walleye and smallmouth next time you get a chance.

Sound like an awesome stealth rig.

I’m thinking about getting the same rig. Do you think this boat would be better off with a 35jet. Boat launches are no issue for me.

Great suggestion! Let me see if I can find my hose fitting.

Generally, a prop is the best choice for a lake but you can use a jet if you want

That is true someone else mentioned that.

Yeah don’t worry bout smashing anyone’s else’s boat. Just keep it moving and ignore them as u do so. Hey u just hit our boat. Don’t no what u talking bout there willis but I’m not trying to stop for shit man.

Got this from the outboard jets website - Can you use any other grease besides Lubriplate 630 AA and why do you recommend against using a lever type grease gun? Any grease of the same consistency (NLGI 2) which is water resistant should do the job. The main thing is to keep grease in the bearing cavity and water out. We prefer a hand held jiffy lube since it does not create high pressure. If a cartridge type lever gun is used, it should be pumped gently! Excessive pressure will invert the rubber seal lips and seals will no longer keep water out.

You can buy a jet pump for pretty much any outboard over 25 hp and convert it.

No there is another small rubber impeller for the water pump. Just like on a prop driven outboard.

@@AlvinDedeauxFlyFishing yep, I doubt the jet impeller creates enough pressure at idle to push it clear up to the powerhead. Mine has a water intake nozzle in the snail chamber that is connected to the cavity under the water pump by a hose. The water pump is the same as an outboard with a prop lower unit. You're in for a rude awakening if you pretend it doesn't have an impeller!

I think so. It will be like having 2x 100hp engines. The big advantage of the jet is being able to use it in shallow and or rocky water. Probably not somewhere you would want to water ski.

On our river a prop just isn't an option.

@@AlvinDedeauxFlyFishing I’ve noticed on your videos. Our trout waters get really shallow and are more or less wading only. Our bass take to deep rock bluffs in the winter. But come spring. Jet’s become king again

Pushes water to the intake and prevents spray from the foot from coming over the transom.

The jet pump has a water pump for the engine. Works just like the water pump in the prop lower unit. So you have 2 impellers in the jet drive.

Awesome Alvin! Thanks a ton for the response! Cheers from Montana.

Actually just purchased a 150/105 Mercury 4 Stroke Tiller. I didn’t think to ask the Guy until I arrived home. Pulled you up.... Saved the Day. Thanks very much

Yes, exactly

It's not that big of a deal to swap the lower units. The hard part is that you need to raise the engine around 5" to get the jet pump at the right height. The jet drive is very finicky when it comes to where it sits in relation the bottom of the hull. 1/4 of an inch can make a big difference in performance.

If you plan ahead when buying a boat/motor combo it’s easy. If you buy a motor with a shorter shaft and a jet pump, you can use a spacer called a bay kit to drop the prop lower unit down to the proper depth. If you already have a prop lower unit with the appropriate length shaft and want to swap to a pump you have to find a way to raise the motor up about 5” like a jack plate or other means.

@@AlvinDedeauxFlyFishing Jack plate would solve that issue

Thanks Joe, so true about the "WFO" or nothing aspect of jets.

Hmmm. Ive owned an outboard jet for 3 years and didnt realize there are only 2 positions for the throttle. You should educate yourself a bit my friend. Most of what you said is false.

Nobody should ever leave the harbor or launch ramp without a kicker and a separate fuel source for it. Here in southeast Alaska, kickers have saved many lives including mine when for whatever reason the main fails. The water is no joke and it doesn't care who you are.

#0% less power so pretty much turns the 50 into a 35. But it will run so much shallower.

Not sure, don't know that boat. You will lose 30% of the power by going to a jet so imagine that.

It is pretty easy to take the foot off and get it out that way. I have just left them in there, no problems so far, but that's probably not the best thing to do.

@@AlvinDedeauxFlyFishing good to know and thanks for the heads up. I figured it would be okay as rocks and what not get in there naturally but this was a larger then usual.

I have run my jet with a rock wedged between the exhaust and jet nozzle without any problems. You lose efficiency though which could mean the difference between getting on plane in a tight spot or vaccuming the bottom and getting stuck.

Yes, that is an addition safety factor that people like about jet engines.

You can get it back up as long as it's not too shallow.

Clams, small fish and sometimes even a turtle! 😂

The 60 should push it, but what you end up with is the power of a 40hp once you put the pump on. Might cost more to get a pump for it.

True, maybe I should have said pressurize?

It will be pushing out water even at idle. How slow you can stay on plane will depend on the hull.

There is a reverse cup that diverts water toward the front of the boat.
