I have a 63' evinrude 75 hp electric shift. I have been looking for the normal holes with the gouges, however i cannot find them. there are two holes above the cavitation plate, one on each side, and there is a airspace between the lower 1/2 of the lower unit (kinda a shroud). I am wanting to test the water pump to see if it is circulating.<br /><br />also, there is a hole, appears to be exhaust in the center back side near the powerhead.<br /><br />I got the darned thing running, now it's time to go to the water.<br />thanks,<br />requa.
