Motor keeps seizing

[KingKoopa562]

So i have a 93 seadoo xp that seized up ..im wanna know what im doing wrong .. everything i learned has from this thread .. so just when I thought i got all the parts moving again i get the sparks plugs back in .. and as soon as it wants to turn on it spits water out from the back and seizes up again..

are you running it on the water hose or is the ski in the water?

 

[KingKoopa562]

Im not running it at all im trying to get just to start

 

[KingKoopa562]

It seizes before it cranks on

 

[KingKoopa562]

It's weird because i can easily loosen it with my hand

 

[Grim]

Where is the water coming from? Have you tried cranking it without plugs to see if water comes out the top? Did it sink or get flooded?

 

[KingKoopa562]

Yeah I cranked it with the spark plugs out and it spits water from the exhaust im assuming... and it was never flipped it just stopped working .. it was fine one weekend and this happened the following.. replaced everything.. starter , battery spark plugs .. solenoid .. before I realized it could have been seized

 

[KingKoopa562]

Once i get the pistons to move again it cranks for a while .. and right before it wants to start it seizes again

 

[Grim]

So no water for the spark plug holes? Do you have a strong crank with the spark plugs out? Normally it is faster than with the plugs in.

 

[KingKoopa562]

Yeah nothing from the holes.. and yes it cranks strong ... it cranks longer with the spark plugs out .. when the plugs are in it seizes after 3-4 seconds

My first guess is the carbs are flooding. Have you rebuilt the carbs lately or has it been sitting for any time. Can you explain the water a little more, that doesn't make sense!

 

[KingKoopa562]

Yea i find it strange too... i cant find anybody with this same situation .. the water caught me by surprise because once the pistons were loose i put the plugs back in and cranked it and right before it started the it just shot water from the back were the impeller is at.. it did that twice..before this its was sitting for about a month.. it was never flipped or anything.. when i turn the flywheel it would do almost a full turn then it gets stuck again.. it only takes a lil wiggle to get it past that part then it free ups again..never rebuilt the cards .. idk about the previous owner

I really am suspicious of the battery. I know you said it was new, but it is possible to buy a bad battery. You can have them load tested at more auto part stores to see if it is good. I would start there.

 

[KingKoopa562]

I can try that ... after do many cranks i do give it a charge because i am affraid of draining it too much...im wondering maybe when it seizes i dont leave the lube in long enough...ill post a video after work... to better explain everything

 

[Spider4real]

Yeah, a video of this might help

That crank should not have a “ hard to spin” spot at all,,,you have either top end issues,(rings/piston), crank bearing issues, or rotary shaft gear issues.

I would oil up the cylinders and let it sit for a bit. Might have some rust forming and builds up on the rings. Pb blaster is good as is marvel.
