    250/260/300/310 power plant

    Hey am looking to get as much info as possible, I got a winter project in mind. is the engine on the 250-310 like seadoo 215,255,260 in terms that they are all the some engine guts minus the super charger, I want to get a 300 or 310 but if the 250 and 260 got the same engine minus the sc psi then I might consider a 250 and rebuild the engine with new racing parts .

    Cases are different, larger bolts (mains on the 300's) crankshaft is different plus lots of other little stuff..... you're gonna do a turbo it wouldnt matter much. What yoi will want is that 250/60 cylinder with the larger water jackets around the cylinders

    I've read many bad things about those 07 cylinder head cracking and they aren't cheap to replace if they sorted it all out on the 11+ 300 models then am golden, a fiend offered me a running 250 07 for 3k

    I happen to like the 300/310 hull better in terms of appearance and I would want to hold on to this ski for a few seasons, 300/310 project it shall be.
