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.
