[culleydog32]

i have a question about my seadoo, a few days ago it started bogging, wont go over 30, i got it home and there was white like cream blown all over the engine, i must add the oil and gas is a 40/1 mix, anyway i pulled the plugs out and the valve cover off exposing the pistons, one side is normal, the other side blows the white cream i aussume it water or oil that managed to get in there somehow,the ski had been tipped over but i always get the water out right away, i also compeletely drained the fuel tank and thats where it sits as of right now, any suggestions would be helpfull i dont want to damge the engine i have only had the ski a few months.

list of things that have been done

new drive shaft
new wear ring
rebuilt carbs, and new fuel lines
new fuel gauge sending unit
new steering cable
new impellor
engine has less then 60 hours on it , 2 stroke 800:seeya:

Sounds like theres water getting into the engine somewhere. Could be one of a few gaskets or I think theres an o-ring too. A milky fluid will be water and your gas/oil mix. But where is the water coming from? That is the question..

hmmm

well its been out of water 3 days and the white oil is still present when u turn the engine over on 1 cylinder, u can wipe the piston clean crank it overr again and the white oil is there again, but why wouldnt it be in both cylinders

that is very strang!! Give it a few and I am almost positive someone on here will have the answer for you.

Still could be some water sitting in the crank. That takes a while to get out. How long have you tried to rid the milk?

 

[culleydog32]

i still have the head gasket off

gonna hook the flush kit up today and let it idle a bit and see if it gets better

My guess would be your crackcase is filled with water. As mentioned, it may take awhile to get it all out.

There is also an area of the crankcase which hold the counterbalance that should normally be checked for water and have the oil changed. Unfortunately for you, with your early version of the 787 engine (I think the change occured in 1998), this oil cannot be changed without dissasembling the lower end. Later versions of the 787 provided a drain plug and a filler plug that would allow you to check this area for water fouled oil and change as needed. BRP also later added this procedure as routine maintenance every year as well as anytime the engine took on water.

so is it gonna be safe just running it pretty hard and hoping it clears out or do i need to take the engine apart, i ran it yesturday and it would run 35 then after a few secs it would pick right back up to normal speed, what would you suggest?

My 97 SPX has the counterbalance drain. Still not fun changing, but better then tearing an engine down.


How is your engine acting when its running slow? Bogging, sputtering, etc?

it boggs down, i replaced the head gasket, it will start pretty easy and when you take off it boggs down , after 2 mon or so it will pick up to full speed like normal which runs between 55-60

i take that back after i ran it today it was harder than hell to get started
