It's a standard utility pump I pick up at Harbor Freight. It was only
$40. I can always replace it with a continous duty model at a later
time. It is cheap enough to carry a spare, or replace it every year.
Heck, an impeller kit is $40 anyway. This setup would only take several
minutes to change out if the pump fails.

Sorry. Carry on. When you said electric pump, I was thinking fuel pump.
The only caution I can think of is that the pump you are using might jam
or clog If it wasn't designed to pump dirty water.

I didn't replace the fuel pump, and don't have any plans to.

The choke circuit only activates the 30A relay. The pump itself is on
a separate 20 amp fuse on the battery selector switch.

I installed a temporary garden hose 2 way splitter on both ends of the
water pump. On the in side, one hose goes to the raw water inlet, the
other goes to a short hose to allow quick connection for flushing in
my driveway. On out side, one hose goes to the heat exchanger, and the
other goes to a 1/4 hose reducer that acts like a weep hole on an
outboard or jetski. This allows a visual indication at all times that
the electric pump is working.

Yeah...that I am an idiot...

The electric pump works great! I had to install a relay to activate
the pump. The relay is hooked up in parallel to the electric choke
circuit, so it will turn on/off when you turn the key.

Not such a good idea. You need to buy a oil pressure switch and power
the fuel pump from it. You also need to pull power from the starter
solenoid S terminal to run the pump while cranking the engine. I hope
your electric fuel pump is of the Coast Guard approved variety.
