At this point he has nothing to lose , worth a try but it looks like he is ready for a new motor . The new stitching pins pull the block together . The kit is $250 vs $3000 either way it sucks and good luck.

So as I start tracking down options, do I need to worry about what will match up with the transmission as a direct drive?
What about the engine mounts? Do I have to find something to fit exactly or is there some leeway? |

Joe, I'm very familiar with the process and personally don't feel stitching is an option. It will never pull the crack tight enough to be water tight. With the closed cooling on a automotive block you typically of add a "stop leak" product. |

Do you have water in your oil , if it is just a cracked water jacket you can repair it in the boat using block stitching , Look up lock-n-stitch I have fixed a few cracked car blocks It works great..

I like that thought process Since you already have fuel injection and the bad parts are the block and maybe head(s) why not get a 305 marine long block like what's in the link below Forget about more power and then you've got 2650 bucks left over to spend on transferring parts to the new long block and getting it installed if my 'rithmetic is right. No calibration issues since all the original fuel injection parts are getting reused. Considering turn around time and effort involved it's hard to beat The more you do yourself, the more you save. Otherwise that 5K ain't gonna get you very far  link Or go the junkyard engine/block route and transfer parts if you're handy enough |

I suspect those 4 things won’t go together. Pick any 2, maybe 3 if you’re lucky.
Fuel injected More power Paying for someone to install Under $5k |

I'm pretty handy through the power of this forum and Youtube, but would prefer someone install it for me.
I don't even have a ballpark of what a replacement engine would cost to begin with or what I am looking for. As this one is only the 275hp I'd like to find something fuel injected with a bit more power to get my inlaws out of the hole a little better. Something under $5k? |

The world is your oyster...
But to speak thoughtfully, we need to understand your restraints and must haves, budget, platform, injection, zero off, brandy-new, this DIY basic, hobbyist/enthusiest or contracted out... etc... |

It is the original 5.0 PCM and I winterized it two years ago. Last summer our lakes were flooded and no one was able to get on the water. That's why the good idea fairy showed up and told us to refurb the interior.
This crack could have happened at any point over the last two years, but we store it in our local caves where it doesn't get colder than 60 degrees. I thought I drained it well enough and dumped in enough RV antifreeze but who knows. What restrictions do I have in replacement engines? Anything that will fit and does it have to be a marine engine? |

I bought it remanned from Center State Engine. came with pan, wp and intake. They will build anything to your spec and the price was right. Discount on shipping to a shop with fork truck. I also had trouble getting it timed and tuned right and their CS was very helpful.

And from an old thread here's a picture Model Year 2000 Throttle body injected I figure the engine tag starts with PLG but he could verify that

5.7 vortec will give you a noticeable increase in hp and all your stuff will fit. Piece of cake if your carbureted. Not sure what you can or would need to do with injection. There's plenty of guys here that do know though. I went from 5.0 old style carbed to the 5.7 vortec last repower and I must say the boat runs quite nicely.

Would be good to know age and exactly which engine you’ve got to start with... carb vs efi etc. Trying to reuse existing setup to what extent, etc?

Earl,
Yes, when that happens it does suck. Sorry to hear about the problem. Was the engine winterized? If so, explain how it was done so others may not experience the same. problem. |

Not sure what the easy replacements for the 5.0 would be. I'm sure someone will jump in. Sorry to hear, that really sucks.

Not really a question, more of a "holy crap I can't believe this happened". We ripped out the carpet last year and are going to lay down Sea Dek when the weather turned cold and we had to put her in storage for the winter. Got her out last weekend and after cleaning up a couple of things I thought I'd fire her up and see how she sounds. Maybe even hit the lake for a spin even though we don't have carpet, an engine cover or many seats.
Charged the battery, hooked up my garden hose and hit the start button. Heard the engine turn over beautifully with that nice throaty 275hp sound...with something extra. It was water spraying out at a high rate of speed against the wall. Lo and behold, I have a crack. So, what size motor should I put in next? Would be nice to be a part of the corvette crowd!
