got the 21 pitch prop on there get's up to 4K RPM no problem, a bit of trim and
I'm at 4200-4400 at WOT -- looks like that's dialed in.

However, After running around for about 2 hours -- I came to something in the
water, so I came to a stop -- the engine sputtered & died Much like an engine
that got too hot. The temp guage never went above 150 -- which does not mean it
didn't go above 150.

I started the engine; and again; it acted like it was hot -- it turned over slow
& then started. I noticed Steam in the back off the water. (that can't be
good)

I pulled the "out" pipe off the engine water pump and turned the engine over
(w/o the coil being hot) and water came out no problefm -- so it's getting
water.

Question is:
Where should I start to look for problems?

Stuck closed thermostat?
water pump in the outdrive (if so -- is it an impeller? And where is it?)

Thanks to all.
