There are pics of this engine already here but I think the quality was real poor.
These were taken a long time ago and the resolution is as good as it gets.
In the rear view showing the water pump if you look in the exhaust port you can see the water out tube hanging down. Not a good show engine as it is almost impossible to not have the cooling water exit into the exhaust.
It is a "salt water fitting" engine with all the brass and copper nickle plated

Enjoy
Ernie

Ernie - do you think those two plumbing valves are original to the the engine? And were they throttled to control engine temperature?

We had one with the same inlet taps. We assumed that one was for the bilge water and one from the lake?? Turn them on or off as needed.

Yes they are original.
Actually they aren't valves. The handle is just an adjustment to prevent one or both of the two inlet check valve balls from opening.
I figure the choices are:
1 cooling water
2 bilge water
3 both closed to blow the water out of the exhaust when shutting down.

That is some clever thinking. I might just try to figure out how to do that on my boat.

Thanks guys
