2 strokes do that. it is normal. and you said you did alot of work to it? sometimes that will happen if you run a high compression kit with a stock piston and you dont jet the engine rich enough. thats what happened to me on my blaster i bought it off this guy who had a cast piston, high compression kit, and the thing was lean as all hell. and my piston looked just like that one, shredded top end, blown intake skirt on the bottom.
im surprised it lasted that long if you treat the engine like the rest of the doo! that thing was an F$%K(NG mess inside ever wash it clean it ADD OIL to it
Bullshit, you thick? Do you not use oil? Your engine got that hot, you evaporated the ocean, caused global warming, and blew up your piston and melted the top... don't think it just happens.. snowman talks snow from his ass, bit of luck and he'll melt like that holy ass peice of shit did..
should of checked out the crankcase cus my blaster's cases got big cracks when the piston shatterd and it was letting tranny oil in and it was a disaster.
Looks like you were running lean. notice the top of the cylinder its all warped and deformed. When you run lean your piston don't get lubed and cooled properly and extreme heat is formed by friction and lack of oil on the piston and that how your piston blew.
it could be becuase of the age of the jet ski but it can also be that you prooly treated your jet ski also you probly did not run the jet ski with oil
is that the intake side of the piston, because on my buddy's indy 650 snowmobile, it was running a bit lean = hot.. and some water from his air box got sucked in the carb, and when that happens it can shatter the intake side of the piston skirt.
The Motor was getting too much fuel.... and a weak casting in the piston.. get a forged piston or something better then stock!!! Yea... That does suck... My car did that... Opps...
125yzmannen has got the right theory but thats not totaly y the reason is is yes the cylinder was worn it was worn big enough to where u got some piston slap or w/e and all that slapping finaly broke the skirt off thats verry common
in my experience with the sea doo engine. its 10x easier to work on those motors if u just take it out.lol..seems wierd but only 5 bolts and hoses hold it on..saves alot of sweat and busted nuckles
by the looks of the top of the piston it look like a bearing was coming apart and if you look at the head there might be a piece of whatever it was still stuck to it. or a ring broke. I dont think it was because of running lean, because it normally burns the top of the piston to wear you get a hole in it.
check the ports and see if it look like something like a circlip or a bearing cage came apart and got stuck on the port when the piston was on its way back down. if seen this a few times not to much on seadoo but once.
Improper break in, not enough oil, and running lean. That is how this is done. Its very common for someone who has no idea what they are doing to have engine failure such as this. Premix with your oil injection during break in, let it warm up, confirm proper tolerances, check your wash and plug chop.
its called piston slap which is common with two strokes, i had a old yz 125 1988 with original piston and cracked the skirting off the piston like yours and jammed the motor up but leaving no damage to the bore.
pistons break that that when the piston to cylinder clearance is too much and the piston wobbles back and forth.... at high r's its slams the bottom of the cylinder and your done
yea, i needed a bottom end on my kx100 and i tried to ride the bike around when it need a bottom and, and i cracked my piston and broke my rings, nasty sound.
god damn id kill that lil bitch in the background screaming....just buy a used piston and used head and sell that pos for 300 bucks ....problem solved ....
it seizes and then the piece that snapps of sticks to the cylinder wall then the piston comes back down smashes it off and throws it about till its ground down and knackers ure bore and ure bottom end gotta be carefull if it cracks a water jacket ure fuked coz it will fill ure engine with water when u put it back in ..
Stop wasting your time and pull the motor out. Hone it/bore it if needed and install a new piston, wrist pin, whatever is not still good and buy a gastket kit. Bolt together, place in jet ski and go ride.
did the rings forge together aswell? and did oyu end up puttin in a repaired motor/used/rebuild or did u get a brand new engine. i think we might up our engine now that we took everything out. the whole engine bay is bare.
you cant rescue this engine xD

Nope, had nothing to do with that...
That is simply a worn out piston, stock cast pistons like to crack after lots of use... Nothing more than simple work hardening.

easy. your cylinder wore out on one side faster then the other causing one side to knock a little more and broke part of it off.
get that cylinder re bored. it happened to my friends cr80 3 times b/c he never got it re bored.

might be cheaper to go that route.
gauge the cost of a new engine with the cost of a tear down and rebuild.
when metal breaks like that, you gotta split the case and clean it to make sure fragments arent still in there to haunt you later.
