So were there no numbers or letters behind the timing arm?

Lucky bastard that’s a 225 promax block. Gotta run the good fuel in that one. No ethanol 91 oct minimum. Might want to pull a head, cc it and measure the head gasket thickness. Could be your issue right there
Does look like an NN stamp. Can you show a pic of the side of the engine.

Congratulations!!! you got a nice motor!!!
Serial number that starts 0G7***** Is probably a 1997 or 1998
0G3******* is a 1996. So, it has to be newer that that.
I will get more pictures tomorrow if I need more to help y’all out.
That is what is commonly known as a Frankenmerc. Definitely a 225 Promax block but with carbs. And no fuel pump.

So needs to have a electric fuel pump?
A couple more questions should I run it with the tstats and poppet valve? I also put a different lower unit off a Mariner 150 i was wondering if that could be some of the problem? Any and all help would be appreciated.
