Kaboom goes the 1300
Well, not sure exactly what happened but my 1300 ported motor finally bit the dust. The front piston got smashed up along with the r&d head. Don't know what really caused this as the ski has been running rich as far as fuel goes and I've added a little bit of oil to the gas everytime. Ski has giving me no problems what so ever and has always ran strong. It was running extremely well this past Sunday, accelerating like a bat out of hell and topping out (I don't know as my gps was freaking stuck all day looking for signal), but top speed felt fast. Here is a pic of just the top of the piston, hope to have the motor out by tonight. Luckily minimal damage to the cylinder wall, millenium can fix that up and I can just clean up the rest of it. Crank will be going off to crankworks to get checked out.
I seem to be having issues with my front cylinder, both motors have started to mess up the front crank rod and cylinder after 60 hours of use. But this time I am baffled as I can't think of anything I did wrong. Ski was running rich, we had just gone through a long no wake zone and ski was smoking like crazy, then I opened her up and let her rip for a good mile and then it stopped.

Hello Shooter looks like something came apart make sure you check that crank good, That is not from detonation.

Rule #1 when it is running the best it has ever run it is about to pop. Can you do a leak test before tear down. Look real good at the crank seals.
