Until I get my Teal on the water the only boat I have is a 19' runabout
with a 5.0L Chevy V8. Except for marinized Fuel, ignition systems,
and corrodible parts in contact with cooling water replaced with brass
the engine itself is stock. The cooling system works well enough that the
water temperature stays right at 170 degrees F regardless of the water
temperature. For about 8 years now I have given the temperature of
my boat engine no more thought than my car engine. The system just
works. Here is how:
The outlet of the thermostat is connected to the inlet of the
engine's water pump with a big hose thus circulating the coolant while
allowing the thermostat to control the water temperature. Basically
the radiator is replaced by a length of big hose. At the thermostat
end of this big hose there is an inlet for lake water from the raw water
pump, and an outlet to feed water to the exhaust manifolds and thus back
to the lake. Until the thermostat opens water flows from the raw water
pump to the exhaust manifolds and back to the lake. When the thermostat
opens raw water is mixed with the hot water flowing through the big hose
and hot water from the big hose also flows out to the exhaust manifolds
and to the lake. Very simple and effective, used on thousands of boats.

Ahhh! Don't you love companies that put enough information online for
you to copy thier product?
http://www.go-devil.com/Go-Devil_Engines/5_5hp_Honda/5_5hp_honda.html
According to the page, one of the options is "hot dipped galvanized
frame". From this, thier frame is just steel with paint!
So, for $229 use this engine:
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=41103
Some steel, some bearings and a universal from McMaster-Carr, some
good epoxy paint, and the prop from a 5hp motor.
Might have to use a special prop, no gear reduction...

There is a company that sells these, "Go-Devil". Unfortunatly, they
are more expensive than outboards!http://www.go-devil.com/
Not sure how one of the cheap motors would take the marine
environment, and being left out in the weather.
Might make an interesting project though, you can get a horizontal
shaft 5hp motor from Harbor Frieght for a couple of hundred. Add some
steel, a couple of good bearings, and preston, boat engine!.

I helped to marinize 1 motor, a 4.5 l staight 6. The trickis to make
a bigger sump and fill it with copper pipe for the water intake. This
heats the water on the way in. Water on the way out joins the
exhuast , a kind of venturi effect which can suck the water through
too fast . if your oil- engine - water temps arnt well balanced you
get stalling , sticky valves, etc. when fitting big v8's into tiny
ski boats theres usually no room for a bigger somp and it is cheaper
to to use the original sump, Therefore your problems start before you
get in the water.
Little deisel are good as thier revs, flow rates of water are just
right.
A thought might be to get a simple briggs and stratten type motor
make a tube shaft and prop to bolt on . Go watch an old james Bond
movie. The one in hong kong with Roger moore, where the car jumps the
collapsed bridge.( I think) A vietnamese friend described them to
me as most of Asia uses them . I saw one on an Aluminium German ww2
landing craft in France . The engine was of course a VW 4cyl air
cooled.
Oarlocks I've used 10 " quite happily for 6 months now. Oars are
simple 1 1/2" square with a1/2" ply blade in homemade SS rowlocks
made from 1/2" round rod
