Since you are in NC, and at anchor, you are not far from BetamarineUSA in Arapahoe, NC.

They offer drop-in replacements for A-4, and can probably arrange contact with a yard that can handle the refit.

I have always talked to Stanley over the years. Super helpful.

Or, you can try this guy, I see his work, but don't know about travel and shipping tools:

Good advice unless you decide to go with a rebuilt Atomic. Where are you anchored?


Fair winds.. Ed

Re: How To Patch a hole on Atomic 4 Gas Engine

You've really got two options for repair. The first would be a rebuilt Atomic 4 if you want a low cost fix. The second would be a diesel engine designed as a drop in replacement for the Atomic 4 if you want to do something of an upgrade.

Re: How To Patch a hole on Atomic 4 Gas Engine

The last picture you attached shows what happened. The hole is the engine block that is missing a piece of cast iron. In the hole shows a shinny part which is the crankshaft journal, where the connecting rod connects. Just above is the connecting rod cap. The bolts are missing. What happened is that the connecting rod broke and whipped around and hit the edge of the engine block and broke the cast iron from inside out. Then the connecting rod cap bolts and dropped in the oil pan. The other end of the connecting rod is still attached to the piston and the piston is now at the top of the cylinder. You are lucky that the engine is still running, usually you cannot start the engine after a major break like this. To fix this... will be very costly, the block will need to be repaired, the crank will have to be rebuilt, and the parts that are very hard to source out, like one piston (maybe more), connecting rod (maybe more), reconditioning of the cylinder head while you are at it. It will probably be cheaper to source out a used or reconditioned more modern engine. All depends who will guide you through this project... Good luck in the repair.

Re: How To Patch a hole on Atomic 4 Gas Engine

Not a joke thread, a person with very little experience with engines. We all started at that point, no matter how much we know about them now.

Yes, the engine is beyond repair; it's amazing that it runs at all. Ninedotsix has given you good leads to get help locally. If you need further help from afar, do post again.
