i have an old marine onan generator. It is a two cylinder diesel engine and the block is almost round on the bottom. I thought it was a cummins but im not sure. I know it is vague but can anyone help.
the other guys are right cummins owens onan. sounds like a 750 kw it is a good lighthouse, you find that it uses about .2 gl an hour of diesel. its some what hard on raw water impellers ( carry an Extra) and you'll need to change the mounts to stop some of the vibration other than that its been very reliable for me. it powers my 53 foot trawler no problems.
