I just purchased ths boat and it has a mercury sport jet 90 hp in it.Took it to the lake today and runs great but when you are crusing about 20 mph it does fine but when you run wide open it acts like it goes out of water or in neutral.t will start back fine but cant run it wide open.


......Hope someone can help me.Its got to be in the propeller or the bearing to the propeller......Thanks

Re: 95 sea rayder jet boat

Does the engine cut off or does the boat just trim way up and just go no where? Is there any vibration at full throttle ?

Sounds like the ride plate may be bent or the intake grate has debris on it . Impeller to wear ring is also a possibility. Post up more info and we'll get you in fine running shape.
The ride plate will get bent if you run this boat out of the water without a flush kit hooked up ! If you blow the ride plate off from running it out of the water the fix is very expensive .

Re: 95 sea rayder jet boat

Cool, I've done a lot of street racing but nothing with classic cars just ricers. I have raced other cars a little and done some bracket racing but at the tome i was street racing I was tired of fixing up my older cars and I was just out of high school and couldent afford gas in them to get to the bigger citys to race and screw around. I had a rusty 69 nova with a 355 and my first car I still have its a 70 Monte carlo with a 402 big block that was completly orignal untill I had to rebuild the engine about 6 months ago because of shot valve guides. I'm the second owner of it. when i did street race it was great i had a 96 saturn sc2 5speed with a turbo and shot of nitrous...and smoked 2 engines and 3 transmissions that way lol but it was fun

I have another thread "1996 bayliner jazz 120 red stator" or something like that but I can start another one about running without a flush kit if you want. I have a ton of questions about this boat and these engines. This my first boat. I'm super busy at work it took me 5 hours just to write this up on my phone ill try and get on the computer when I get home tonite.

Hey kend, I took the #1 spark plug out to check for spark again and it started up magically.. so i put it back in and nothing...I thought maybe it wasn't cranking fast enough because of the compression so i put a charger on it and set it on 125 amp start well it started,I shut it down waited a min and cranked again ....boom blew the bottom plate out...I really really wish you would have just told me if it would blow like you did on this other guys boat...but the damage is done I'm screwed. As for now could you tell me what I'm looking at and can do here? Please

So sad :( first sign of life and then instant death
