Re: What year 4hp evinrude?
Hey Cora, My '69 4HP Evinrude discharges the water through the engine exhaust. To verify operation of the water pump, look for a spray (not a stream) from the exhaust vent about 2/3 the way up the lower unit.<br />Of course, I'm talking about a '69 model, your '78 might be different.<br />See my post from 5-01.
