    Trim issue

    Jump trim solenoids. If OD goes up and down then you have a bad connection somewhere. 1991.... My guess is that your rams are locked internally. I had to totally rebuild mine. Seals get old and let in water.

    Alpha one gen II growling noise when turning

    Unfortunately, being stranded 50 + miles offshore is a bit different than differential freezing up on a highway. An ounce of prevention is always worth more than a pound of cure. Owner's choice....

    Alpha one gen II growling noise when turning

    That's an old boat. I suspect many things possibly wrong. With it in water and running and looking at drive shaft, does shaft wobble? Some shafts you can see. Some U can't. Or feel the back of motor/transom assembly for vibrations. Does it wobble more when turning with drive torquing? If you...

    Risers and manifolds at the same time?

    You nailed it! I wished SS risers worked and were reasonable $$$ for my antifreeze cooled V8 motor.

    Risers and manifolds at the same time?

    It has been my experience in salt water only! Cast Iron risers go first: 4-6 years. In many cases when inspecting, you can notice wall thickness reduced on manifolds where they mate with risers. Remember, the block and heads are rusting too. If you get 10 years on a salt water block w/o...

    red-lock is great but don't expect to ever remove bolt w/o a lot of work and maybe heat.

    Black wire from thunderbolt iv harness/est dissy

    I don't know if MC added extra wires for possible accessories. I had a bunch of colored and black grounds. I grounded the black ones, and nothing smoked. Thank God.

    Gauge making me crazy

    But are they "balanced? This is simple to check and will rule out impedance as the problem. Been there!!!!!!

    Alpha one, noise from gimbal bearing area, new gimbal bearing, no water intrusion. Stumped!

    Very clean, but that's an old boat and may have transom rot that causes flexing and the noise. The seals are a pain to replace, but unless yours is warped, I don't suspect it is causing the noise. I am restoring an 86 SR Amberjack. I had to replace transom. What a job!!!!!! Are you sure it is...

    Gauge making me crazy

    Perhaps former owner replaced sender or helm gauge, which was the incorrect impedance?
