Hey Everyone
Guess I'm just feeling the need to vent a little but here's my tale nonetheless, you may find it an interesting read. At the end of April of this year I bought a nice 1996 SeaDoo XP from a gentlemen 4 hours south of me. Paid a bit of a premium price compared to other XP's but that was because it was a freshly rebuilt motor built by a man and his son who rebuild SeaDoo's and sell many of them per year, he also stated that the carbs were rebuilt with a carb kit. Thing even came with a fresh battery and a good once over I was told. The SeaDoo was in great shape and we even spoke to a past customer who had had a great experience with the seller. It sat in the garage at my house in the city until the end of May (basically a month) where we removed the VTS and replaced with the manual HX trim, replaced the fuel lines and cleaned the fuel selector, polished and re-decaled it, new beeper, new grips and other little details. Anyways with a good background in mechanics and lots of advice we broke the SeaDoo in as perfectly as I believe was possible. Only SeaDoo synthetic oil was used, a little extra was mixed with the fuel. No high revs at all for 5 hours with little time spent at any one RPM, the SeaDoo made it to 6 hours over 3 weekends before problems happened.
First...coil problem was causing a misfire so our mechanic fixed that for us by replacing the coil - $200
Second...problem still persisted somewhat so he ordered up a stator - potentially $400
Third...before the stator arrived he did a quick compression test and noted the rear cyclinder extremely down on compression.
The mechanic we take our stuff too is as trustworthy a guy as one can hope for, he recently rebuilt our early 80's 75hp Mercury outboard and the thing is like a brand new motor, one turn of the starter and it starts up every time. He's a high performance outboard guy, he's got a great reputation on the lake so when he takes apart my XP's engine and tells me the thing was never really rebuilt, I believe him. Here's the picture dump.
As you can see the piston is quite fried, amazing SeaDoo makes these things with such a small space between the top ring and the top of the piston.
close up!
The next few pictures will show the uneven crosshatching on the cylinder walls along with the dark spots that indicate a really really bad job of honing the cylinder, if it was done it was done by hand without giving two s***s.
The oval shape and missed dark spots would cause uneven heat and friction
And the resulting damage of the ring being slammed into the head...
And the Rave's that were only 6 hours old from a fresh rebuild
Anyways I'd like to hear your thoughts along with share my story, I don't believe much more was done to this motor than the throwing in of new piston rings and a quick cylinder bore done incorrectly. Not much we can do about it really as it is a buyer beware world we live in. I did call the seller who brushed me off and I understand his reasoning to some degree, we could have abused the thing and blew it up in an hour. Still can't help but feel a little screwed though. Anyways thanks for listening, what do you think?
