The engine doesn't know it is in a marine application.
The only thing to watch for is that after the sleeve is installed and bored out to match the other cylinders is that the cylinder/s next to the sleeve need to be honed straight.
Also check the connecting rod to see if it got a little bend in it. If it is bent replace it. I think I would just replace it when you have the new piston installed.
If you plan on running this engine in a street application then the camshaft will need to be changed also. The marine engine must produce horsepower as soon as the throttle is cracked open in order to propel the boat out of the water and onto "plane" with only the bottom third of the boat touching the water. With a camshaft producing that kind of torque the engine will not pass smog testing.
