My friend just called me today and said he had motor trouble last night and since I get on here all the time and read what's going on, I figured you guys may be able to help point him in the right direction. These were his words exactly: I was running down the lake when all of the sudden she just sat down on me so he shut it off, now keep in mind none of his alarms went off when this happened. He started it back up fine, went through his check codes and everything checked out. He put it in gear and hit the hot foot and the bow stood straight up on him for about 50 yards; he said it felt like it was only running on 3 cylinders then it hopped up on plane and did fine back to the boat launch at 5000 RPM's. He did say it's making a funny noise, even at idle. He took it home and this morning did a compression test. I'm not sure of the numbering system on these particular motors but if you're looking at the back of the motor, the top right had 0 PSI, the middle right had 60PSI, all other were at 120. Could this be something as simple as a head gasket or does it sound more serious than that?

Oh yeah, he said he took it back to the lake today after the compression test and just backed the trailer in and left the boat on the trailer and he said it fired right up. He checked the oil levels; they were fine. He checked the oil tank bulb and said it was hard too.

Thanks in advance for your time.

ChampionMan, SEAHORSE, all ears guys.
