    77 Evenrude 15hp Cooling system

    Air worked. Water flows both way. Ordered new grommet and gasket. Ready to reassemble when they get here. Thanks everyone!

    77 Evenrude 15hp Cooling system

    Good news, better news, bad news. I got the power head off. about half the gasket turned to superglue. I forced an old wood chisel in at some extreme angles and broke it loose. Once I got the tubes off of the power head I found that the grommet is completely intact. It’s fairly new. The bad news...

    Is the area I described as being crusted where the shaft and Lower unit join safe to apply heat with a Map or acceteline torch?

    77 Evenrude 15hp Cooling system

    It’s supposed to. The lower housing is completely free from the power head. The power head will not break free from the the other components below the housing. I suspect the larger tube is seized to the place where it mates to the area where the shaft and lower unit join. I’ve been treating that...

    I’ve also disconnected the throttle linkage near the carb, fuel line.

    Six bolts from outside the housing and three from inside.

    It should, but it’s stuck. Other than wobbling, it won’t budge. I’m going to start on the crusted area in the photo with salt solvent and brass wire brush later.

    77 Evenrude 15hp Cooling system

    Ok I’m at an impass. Everything is disconnected, bolts are all removed. The power head is broken loose from the gasket and it wobbles around inside of the bottom housing freely. But I can’t get it to lift out. I suspect it’s the same salt crust crap I’ve been dealing with all along. There a...

    I suspected the grommet, but dreaded replacing it.

    77 Evenrude 15hp Cooling system

    I’ve begun the process of removing the power head. Stay tuned. I had to watch a video on YouTube before I started.

    There is only a dribble coming from the pee hole. Prior to repeated flushing with salt solvents there was nothing coming through the pee hole.

    Pee hole is not plugged.

    77 Evenrude 15hp Cooling system

    I have a 77 Evenrude 15 hp that I bought used. After about 25 hours water quit coming out the pee hole and started coming out the exhaust ports instead. I replace the water pump, then pulled off the water cover on the engine. Everything inside was covered in salt. Obviously a PO ran the motor...

    2003 Mercury 125 Saltwater - Replaced Oil Level Sensor, Alarm Won't Stop

    I recently had the engine alarm come on. Upon examination I found the water pump was working properly, the engine block was cool enough to touch comfortably, and the engine had not over-revved in recent memory. I've gone in and replaced the oil level sensor with a new Merc part. Yet, the alarm...
