Chrysler inboard motor identification

[Papa Harry]

I purchased a 1986 Marinette with a Chrysler Eng. Can't find ID tag. It has a black plastic cover on top of the Engine with '275 HP 5.9 L' can I assume it is a 1986 360.
Are all 318's 5.2L and all 360's 5.9L Would appreciate any help

It's a 360 with center dump exhausts. I have a couple of 360s in my 85 Marinette 32 footer. Great engines.

Check for a stamp on the block. Look on the water pump face of the block, just below the head, in front of #1 cylinder. Maybe an LM360 stamp.

There are also casting numbers on the side of the block near the expansion plugs.

I'm not saying it is not a 360.

Assume?? You'll need to find the numbers to verify what it is. Anyone can put a plastic cover with a number on an engine.
