And couple follow-up questions more..

Why wouldn't you NERSTROM warm up the engine without a propeller? Because the motor won't warm properly?

And what two stroke oil you recommend? I have used Castrol A747 on yamaha 70ces and OMC stinger and it has worked fine so would it work on FR31-M too?

I think what Nerstrom is saying is that you need a load on the motor (whether a test wheel or propeller) when warming it up.

I'm surprised OMC would go to all the trouble of casting a special block with the exhaust on the other side! Does anyone have photos of its interior?

looks like the straight in, bridge port with finger ports is what i'm thinkin. load on , makes heat, or more heat. did see a merc 850 cc special moda once, it had a head gasket.... not lookin like thats got a thermo in it, so work is the only way to get to temp.............
