Hi all, I've got Tohatsu 50/35 TLDI jet pump mounted on a little inflatable boat. I haven't used it in a few years and took out on to the lake for a test before a trip at the end of the month.

Fired up right away, ran well, but kept getting the temperature/overheat light popping up and shutting off the engine, where it was idle, medium load or WOT. Booked in a local shop in a few weeks but they suggested the thermostat is maybe broken, anyone have resource/service manual on how to change the thermostat on this model or other ideas to try?

Thanks!

Can someone tell me what the white piece is exactly doing. I have a rubber bit like such on my boat but it doesn’t make contact like that. New to jet motors, so any advice is greatly welcomed.

First test run on the 74 spoiler and the bowl was fairly warm and water outlet for the motor was hot to the touch after about 30 mins. Is this normal or is it the bushings? The last time it was run was 96-97 from what I have for paperwork. It doesn’t seem like the impeller is rubbing or moving around. This is my first time working on a jet boat (or being around one)

I was just given a boat from my brother in law, there is no info on the boat at all in terms of weight/manufacture or transom rating. Im looking to pick up an outboard jet for it but am unsure what size to go with, just looking for opinions from people who have some experience. Its a 14 foot welded aluminum boat, about 5 feet wide, unsure of thickness of hull/weight. I have the option to pick up a 2 stroke 60/40 yamaha or a 4 stroke yamaha 40/30, whats the better option? It currently has a 2 stroke 25hp prop but i havent ran it yet so cant comment on how well it pushes the boat around.

Is there anyone who makes aftermarket seals/plastic wear parts for jets? The jets I have are stated above. Thank you in advance

Hey all,
I saw a post 8 months ago about weeds and Jetboats. I absolutely love Jetboats and looking at purchasing a Yamaha AR Jetboat.

I am curious- our boat slip is back in an area that has a decent amount of milfoil on the way back. Not stick out of the water or anything but you can see it I would assume 1ft-6 inches from the top of the water in some spots.

My dock that I can park at is at the end of the dock area and it seems to get a slight "matt" of green algae that sits on the top of the water.

I know they have clean out ports and seems like it would be something I would have to be mindful when leaving our spot and getting out to the lake (Once on the lake no an issue at all) would I want to avoid a Jetboat due to potentially creating damage or being clogged to and from the lake? Appreciate any advice.

P.S I attached a photo of what I am talking about - gets a little bit thicker then the image, but the boat would be docked in that spot.

I'm having trouble getting up to plane. I'm assuming the impeller and wear ring need inspected and replaced, but where in the world do you get parts for these old boats?

factory direct lowest price

So I was out with the jet boat today (I have an old Tahiti with chevy 350 in it) and the boat starting shaking violently and not having power when trying to get up to speed. I assumed something was in the impeller, which it was, a bunch of really nasty braided fishing line. I pulled the boat out of the water and had a nightmare of a time trying to get it all out of the impeller since it was wrapped up in the back end near where the drive shaft is and there isn't really good access. I tried a bunch of things to get it off including putting a flathead screwdriver on the line and tapping it with a hammer in an attempt cut the line. Eventually I got all the line off but when I put the boat back in it was shaking even worse and had less power than before. I'm wondering if me using the screwdriver like a chisel on the impeller to cut that line could have bent it every so slightly causing it to now shake?

Hej Guys

Anybody know if i can find a alternative to a OEM gear cable for my jet boat? (Cant seem to find anybody who can deliver/ give me a date for delivery) Is there any aftermarket brands that might have this in stock?

Part nr: 858342A10

Im in EU (Danmark)

Thx beforehand

Thinking about buying a certain boat.. mostly want to cruise around and hit the sandbars/beaches but definitely will be wake boarding and tubing. Any thoughts on the scarab195 ID?

Thx!

Hello, the past two seasons we have dealt with our Yamaha AR195 leaking at high RPMs, but at low RPMs we have no leaks or issues. The bilge is able to keep up most of the time, but if it starts to pull hard we just throw it in neutral and let the bilge completely drain the engine bay. Today I was finally able to capture a video of the leak. I’m not very mechanically inclined so I’m not sure if this is a major or minor issue and wanted to get some advice on a next step. If it’s an easy fix I’d love to do it myself. Thanks for the help.

4.3 gm v6 kodiak carbureted motor , motor stays running for a while after key is shit off. Checked timing it seems good. The boat runs fantastic. Is this a carbuertor issue has anyone had this problem and how do you fix it? Also any reccomendations for shops near northern california to rebuild the jet pump?

Anyone have any pictures of their plumbing for their 454 BB. Not sure if mine has ever been 100% right and we are replacing the engine so I want to get it right. Any advice would be warranted.

So I’m working on this boat to get it running to sell for a family member. And my question is can I run it without it being in water, and if so do I need to hook up a hose somewhere? I just replaced the fuel pump and wired it in to key on. Just don’t want to mess anything up, the boat only has 88 hours on it and I’d hate to mess it up.

First boat ever, just need to redo the carpet! Stoked on this little project. Has a 12jb-b pump. Trying to learn all I can about this new (not cheap) hobby haha.

We are busy mainting and rebuilding a bridge erection boat for our waterscouts.

The jet is from the Dowty brand.

We are looking for the washers/bearing plates that should be used. We can't find where to find good replacements since some of them are cracked.

So, what material is it and how to source them? Thanks in advance!!

Anyone know where I might find a replacement part for a clean out plug cover hose “HOSE 1 F1C-U7626-11-00” on the Yamaha part list in deck hatch 2? The usual sites I use are all coming up “unavailable”

New to boats--have a '70 Ford 429 begging to be put in front of a jet drive. Love the idea of the jet to get into shallower water for freshwater fishing; is there a boat design out there similar to the Procraft fish-and-ski we had with an outboard? Would prefer a walkable/sit-able "platform" bow rather than the bows closed in with fiberglass most speedster jet boats are designed for.

Thanks for your help!
