First sea trial. Boat ran for a couple hours. Cruising is about 37 mph. Everything was fine for the first hour. I tried not to keep it at WOT for most of the time.
After an hour we started noticing it struggling when we throttled down. Then the motor died.
Started up again and as long as we maintained cruising speed it was healthy so we headed back to the dock. About a mile away I had to throttle down and it quit again.
The motor would start up, but as soon as I engaged the gear (forward or reverse) it died.
I tried letting it idle and it would die after a minute. We repeated this three times. Then left it. Had to paddle back to the dock.
Got home and hooked it up to the hose. This is about 45 mins later. The motor started up and ran idle for fifteen mins. No problem.
Info
1976 Mercruiser 165 HP
MC1 Leg.
I replaced plugs and wires a week ago.
I put 5 oz of seafoam in the crankcase, ran it on a hose, and then changed oil a week ago.
Replaced water pump yesterday.
