yeah all that checks out!

Hey guys i need your help/suggestions. I have a 1991 superjet SN. This past winter I rebuilt the engine, new gaskets, new starter, new bendix, new coil, rebuilt carb. Im having some issues now. I can start it out of water and it seems to throttle up just fine, then when i put it under load i...

Did what you suggested, had it on the trailer and right where the exhaust comes up to the manifold i had water spraying all inside the hull. I also as a precaution replaced the seal with surf seal. I love the surf seal, i feel it gives it a much better seal. Thanks for the help.

Not sure how to locate it? Everything is standard I didn't know there was a water line on this thing! What's do you guys think of the surf seal product?

Hey everyone! 1991 yamaha 650 superjet. Ski has new gaskets new starter, several other new parts! I put it in the water today and everything was going great after about 5-7 minutes of riding the hull was full of water! Pulled the ski out and pumped the water out. Got the ski running again so I...

It is a pretty good time. Let me me know if you come this way this summer I'll show you around the lake.

Flips and :-):-):-):-) Doesnt have to be flat water, no! But if so all the better.

Hey guys ive posted a few times on here and after watching YouTube videos I wanna be able to do what they are doing just need to know what to put on my jet to help it do that stuff. I have the engine out right now to replace a seal around the crankshaft so I thought I might as well do stuff now...

im having the exact same problems with my square nose. I replaced the carb the other day and it didnt help the problem. I replaced plugs, the breather tube coming from the gas tank, the fuel filter, completley drained the gas and put fresh in. I cant figure out whats going on with it. I was told...

I've got a 91 Yamaha SJ SN with new blue metallic paint and new hydroturf I'm looking to unload

Do you guys think my compression could be bad? What's the recommended amout per each side? Would the compression be bad if it still ran great at times??

I was hesitant to do it myself but I got the old one off and did exactly like you said. Had a clean clutter free work space. I got the carb off and on and exactly how it was. However, I'm still having the same issues!!! I'm at a loss.

That's actually what I'm working on right now! Thanks for the advice I'll let ya know!

The needles seem to be operating good! Apart from ripping the entire carb off I'm at a loss of what else to do! Any other suggestions? Thanks again for your help!

What needle are you refering to specifically? I have little mechanical knowledge. Also the seat don't really know what you're refering too! Thanks for your help!

Tried cleaning it no luck! Anyone have a used carb I could buy?

Problem typically only exists in the water. When it's trailed I can start it up and throttle it up pretty good. Ski sat all of last summer due to accident with the pole snapping in half. Gas was completely drained and tanked dried and fresh gas put in. It's just a stock 650. How do I tell what...

Okay so I'm having issues. 91 Yamaha Superjet. New fuel filter new battery new plugs new bilge new breather tube to gas tank. What the issue is im having is while I'm idling the ski runs great when I throttle up it goes about two seconds and dies on me. It starts back up idols great, I throttle...

I have an aftermarket bilge pump in. I ripped the syphon system out and wish I hadn't because I am getting a ton of water in my hull. It's causing me to have issues as far as bogging down and not running right. Help

I replaced the breather tube after the problem and made sure the flow is the correct way. I have a feeling I'm getting water into some place it shouldn't be like you suggested. How do I check to see if water is getting in the carbs? Thanks for your help!
