2007 sx230 blown motor HELP!!!

[ShallowWaters]

So here in Michigan was what we call hot boat weekend this past weekend. Tons of boats. Anyway I sucked something up and it ended up blowing a hole right in my block because it over heated and I didn't notice till it was to late. Need help with getting parts to fix it. Anything will help.

Wow @ShallowWaters I have not seen a MR-1 blow out the casting like that. I have no experience but do suggest you start watching craigslist for a FX waverunner with the high output MR-1.

I agree with @buckbuck on both points. WOW!

SBT has one for around $2400. Just hope it's the right one. Looks right and says it's right. Crossing my fingers.

Are you sure your core is good?

 

[ShallowWaters]

I do not yet. Have to get it apart and find out what all messed up.

well... i would say the block is no good!!

Sbt talked me out of using them. They bill something crazy like $100 a week if your core is bad until you can provide a working core. Your option is to buy a new block for about 5k (block only, not short block), then see if the piston/crank are ok and can swap, but chances are you need at least a rod and piston. The fx140 regular is the no ho engine, and the fx140ho is the same ho engine. I bought a fx140 to swap into mg boat, but that's running on 3 cylinders and I need to trouble shoot that too! Tool bad Yamaha stopped selling long blocks.
