Why is the P-60 positioned backward from the IH tractor version and other marine engines backward from their automotive counterparts, front to back?

Marine engines were often installed this way. The size of the flywheel and the angle of the motor allows for a lower profile, the shaft can be closer to the bottom of the boat.

Now I'm no expert but I recall an old bloke once telling me that the thrust of the propellor shaft affects to bearings. It certainly seemed to affect later model marine conversions.. Not sure about the more robust motors from pre 1940s

Don't forget most if not all marine engines have a reverse gear between the engine and the automotive or truck engine. There is typically a thrust bearing aft or part of the reverse gear that takes the prop shaft thrust, transfers it to the casing and in turn the hold down bolts, screws what have you to the engine beds which transfer the thrust to the hull.
