Engine dead, need to rebuild

Was out yesterday, had a great day wakeboarding, on the way back to the marina, the engine misfired, slowed down and engine died. Engine wouldn't start, so I removed all the spark plugs and a big chunk of one of the spark plugs was missing
Im guessing a piston cracked, anyway, oil leaking on that cylinder and no pressure. I got back to the marina luckily running on 7 cylinders.

The 2008 x2 is quite new to me, but engine Indmar MCX has almost 1500 hours on it and wasnt taken care of as best as it could have been. I think a rebuild will be cheaper than a new engine, I've never rebuilt an engine before, but have read a lot about it, I will be getting a workshop to help me out on the job, but I will need to get the parts. Obviously wont know what to replace until I get it all open.

Im wondering if anyone can advise on what not to do, can I use normal car parts, pistons, rings, gaskets etc. Or is there anything special I need to use?
The MCX is basically the same as a normal GM small block is it not? So could I use an engine rebuild kit like this http://www.summitracing.com/parts/FEM-CSMHP766-400/? And ill have a machine shop check the heads out and do a valve job.

I think this is a good thing anyway, it was bound to happen eventually, im just glad it happened and didnt get completely stranded out on the water, made it back safely, and hopefully the damage is repairable. I just want to get the engine back to a good reliable condition so I can take care of it and put 1500 or more hours on it without any problems.

Appreciate any advice.

I feel your pain just got finished with the rebuild of the predator in my x10. We were able to get it in and out of the boat with a regular hoist after taking the heads off without any issue.

Here is a link to the thread.

I had the same thing happen to me last fall.
I removed the engine and disassembled the motor then took the parts to a auto shop here in town.they were able to bore the cyclinder walls over put new pistons in and bearing,etc,etc.complete valve job.
Motor work was alittle over 2g's way cheaper then a new motor.

Good luck,Hope this helps.

I posted my link

Thanks for your replies and links. I actually already went through your threads, some good info and made the whole things feel less difficult.
Did your machine shops source parts for your? Or did you buy them? Where were they from?

My shop sourced all parts for me, went with higher grade than what was previously there.

Thank for the replies. I live in Bahrain its a bit harder to source good parts so will likely be ordering of Summit, Ill be in Charlotte, NC in 2 weeks time so might try to bring some things back with me.
A bit busy at the moment with the formula 1 race this weekend and having a support race myself. Will try to get the engine out and opened up next week so I know what I need. Will be documenting this rebuild with lots of photos.
