    Help with motor height adjustment

    The motor looks to be too low. You want the antiventilation plate at the surface of the water or above. Once you get the A-V plate on the surface, the rest of the up adjustment is by trial and error. The higher the motor, the less effect trim has. You want the motor low enough to allow the...

    Simplest 2 Battery Setup?

    Buy a battery switch and connect both batteries to it. Set it to both for running so the motor will charge both batteries. When you are stopped and relaxing, set the switch to one battery, saving the other for starting the motor. Easy stuff.

    Trim sender not reading correctly?

    They are pretty inaccurate. When trailering, listen to the sound. You can tell when it is all the way up or all the way down. No gauge needed. When running, trim by feel and sound of the motor. Again, no gauge needed.

    1981 mercury tower of power 115

    That could easily be dirty or mis-adjusted carbs as well. I would recommend an OEM service manual. It would be pretty easy to check the idle pickup timing and max spark advance. If those are on spec, it would be time to check the carbs.

    1979 1/2 115hp Mercury Tower of Power - Controls

    One more thing. The control I cited has a different electrical connection that your motor. You would either need to graft it to your wiring harness or replace your motor harness. Your motor should have the ADI ignition with six ign coils. If you check the parts list of a later model ('86)...

    1979 1/2 115hp Mercury Tower of Power - Controls

    Most Mercury controls will work. I bought one of these. It has the power trim switch on the handle, which the original doesn't. Alternatively, If you can find a junk Merc control, you can replace the handle, as they come off with one screw. Side Mount Remote Control Box 881170A15

    Won't go over 4,000 RPM

    You can get a prop with a fixed hub, rehubbed by a prop shop. If the prop is newer, it could have a modular hub. You can buy a new hub for that kind of prop and install it yourself.

    Those rotary steering systems will operate backwards, if the cable is installed in the wrong hole. Your cable looks to be in the bottom hole. Try unscrewing it and install it in the top hole.

    Won't go over 4,000 RPM

    Was the boat going 11 MPH at 4000RPM? If so. you spun your prop, or chewed the daylights out of it. I doubt changing the water separator will fix it.

    No ignition power

    Sure, try paddling a boat larger than 16 foot. With any kind of wind or current, it won't work. A boat pole that you can push off the bottom is more effective.

    Outboard repaint - need suggestions on materials

    If you want a good color match, you will need OEM paint. Perhaps you can buy it by the quart and spray it. You will need an airless sprayer or compressor and HVLP sprayer. This year I did my Johnny and Merc OBs. I used a Rustolium marine enamel, white for Johnny and gloss black for Merc...

    OK, that seems pretty clear. I was quoting ADI specs from my 90s V6. What fuel did it originally call for? Regular 86/87 octane or something else.
