Took out the boat for the first time yesterday with the new to me '86 Mercury 150 XR2. I was leary about the oil injection, not knowing if it was working. So just in case, I mixed the gas in the tank at 75:1. Boat fired right up and ran great. Took it out on the water, it was scary how fast we were going. Motor was running beyond my expectations. So we set off and after about 15 minutes at 3/4 throttle, i start hearing a clanking/banging sound and immediately kill the engine. Try to restart it and the starter could not move the flywheel. It seemed to be seized. So I pulled the plugs, the #6 plug was fouled, the rest were dirty with some grit. I sprayed some wd40 in each cylinder and bumped the iginition, starter was able to spin the flywheel. So i put it all back together and tried again, it started but there was the same clanking sound. But it just sat there and idled in neutral. I put it in gear and it would go, but giving more throttle would just kill it, so i limped home.
Now i go start it, and it runs fine in the driveway, so sounds, revs up great. Any ideas? I am stumped.
