Salt or fresh? No matter I would be concerned about raw water cooling. I have
seen condensers on steam powered boats that were no more than a pipe in the
water run along the hull.
All in all if the vent is built with keeping splash out of the cover you will
likely not have any problem with splash on the motor. When you took apart the
outboard was the motor water spotted? Your controller is more susceptible to
water damage than is the motor.
If you use copper for a coil then make sure you electrically isolate it from
the outboard casing as galvanic corrosion will eat things up quickly.
