    85 Yamaha 90HP lower unit slop. Is this acceptable?

    I have a 78 evinrude 115hp outboard. Its a 4 cylinder. Has 120/120/120/90 on compression. I took off the head, and the low compression cylinder looks like it had a ring issue, as the piston is dinged up on the top, and some on the cylinder head. The engine runs pretty good, besides a little...

    1990 Johnson 50hp - Trim sending unit??

    I have a 88 sea nymph that has a 1990 johnson 50hp VRO motor. In one of the compartments, I found a trim gauge that matches the rest of my gauges in the console. So, im guessing the original motor for the boat had a trim sender, and this johnson may not, so they removed the gauge. My question...

    mid 80's Black Max 150 Compression issue...

    Im looking at a boat that is having engine problems. The owner says 5 of the 6 cylinders have 100-110psi and the 6th one only has 50psi. It is the bottom left cylinder. What are the chances that this is just needing a head gasket? Or am I just looking at a full rebuild? Thanks!
