I blew my 2000 200 hp Ficht. When the dealer put the new powerhead on and did the diagnostics they could not come up with a reason why the old one blew. The injector tested ok as did the oil pump and there were no fault codes in the computer. It looks like the #6 piston detonated before or after the rod broke. I think the piston went and then the rod broke. It doesn't appear there was a melt down. It almost looks like one side of the piston went or something failed on one side of the wrist pin as one side has a hunk of piston still hooked to the pin and the other side has nothing. The biggest piece of piston is about golf ball size. When the motor went I lost power and then the clattering started which to me would mean the rod didn't break first. I had to run it a little way to get to safe enough water where I could go on my electric. (Maybe 1 minute) Things got beat up in there from that. Since diagnostics and testing of componets after didn't find anything wrong can I assume that what the dealer is telling me is right? They say it was just part failure. Either the piston or rod broke. I don't want a costly repeat of a blown engine because of a bad componet not working. Any suggestions are greatly appreciated.
