    very cool carb and intake manifold causing moisture

    FR, the "stove" in old carb motors was to heat up the automatic choke, and cause it to open when the exhaust manifold (and engine) were warm. It was not designed to prevent icing of the carb. Icing of the carb is only an issue on airplanes., and then only at altitude It does not affect boats.

    What to do with old 2 stroke mix

    Carefully use it to start a campfire. I normally use kerosene and 2 cycle oil, since K is less explosive.

    1998 Evinrude ocean pro 200

    Power to the ign keyswitch powers trim gauges, fuel gauges, and anything else someone has hooked up. I powered stereos, lights etc, at one time in my boating career.

    1976 Merc 20hp power loss, high fuel consumption, one plug clean one black

    OK, so fuel pump in the carb. I never worked on one myself, but most 2 cycle fuel pumps work the same way. A leaking diaphragm allows fuel from the fuel line to get into the crankcase, where it slouches around and can foul a spark plug. I would think any 1/4" inline filter would work.

    1976 Merc 20hp power loss, high fuel consumption, one plug clean one black

    Your fuel pump is powered by crankcase pulses. If the diaphragm has a hole, raw fuel can leak into the crankcase flooding the lower cylinders. Rebuild kits are cheap and easy to install.

    1998 Evinrude ocean pro 200

    My '98 Johnny 150HPV6 uses a 20A fuse. I would expect your motor to use the same. It also sounds like you have a short somewhere. Look for melted wires where the boat harness plugs into the engine harness, and under the dashboard where wires power the trim gauge and tachometer. If not...

    Painting my 1989 Bayliner, Need some advice

    A one part polyurethane paint is not recommended for below the waterline use. The paint will likely fail a few days into water immersion. Imron and Alwgrip are the two part polyurethanes that yachts use. Both are expensive and are recommended for pro use only. Epoxy paint does not give the...

    1978 Mercury 140 low compression

    It is very unlikely that the cylinders are all at 68-70 PSI. It is more likely your compression gauge is bad. If the cylinders have the same compression (within 15%) the motor is good. I would check the link and synch. That motor should be a distributor model with battery powered CDI...

    Mariner 40 bottom carb fuel leak from Throttle Plate Rod

    Make sure your inlet needle is sealing when the carb bowl is full. If the carb bowl overflows, it often leaks there.

    1976 Merc 20hp power loss, high fuel consumption, one plug clean one black

    Check the fuel pump diaphram for a leak. A leak there can foul the lower spark plug. Are there droplets on the lower spark plug? Dropets signify water getting into the cylinder, likely via a bad crankshaft seal.

    steering cable stuck

    You can buy a mount made to hold the steering cable, at the steering OEM's web site. They were used for motors that do not have a tilt tube, like the 60's Johnnyrudes. The mount will bolt to the splashwell and support the steering cable and steering rod. it will also be rust resistant.

    Mercruiser 4.3 Alpha One problem - loses power

    You might check the antisiphon valve in the fuel pickup tube and the fuel tank vent. Om my SeaRay, the fuel pickup tube had a filter (not just a screen), which became partially clogged. It limited the RPM of the engine, until I cleaned it.

    Water

    Not normal. Remove cowling and run engine to see where it is coming from. Possible it is malfunctioning poppit valve. Could also be something simple like telltale hose fell off.

    1979 Mercury 70 EL Thunderbolt Kill Switch Install

    Yes you need a switch that closes when tripped. That looks to be the correct switch, however, I would hope they would explicitly tell you it's function.

    Can you spray paint a prop?

    This thread has piqued my interest in painting the speedboat prop an interesting color. So far it is has been black. Grey and white are not what I am looking for. Gold, Chartreuse maybe.

    Can you spray paint a prop?

    Gee, My paranoid thoughts are that prop companies intentionally do a bad job painting props, so the paint falls off if you use them. That way they can skirt issues with prop performance. My paint always stays on, unless you hit bottom.

    Painted Metal Flake Boot Stripe Repair

    I had thought most metalflake was paint. It was base coat, flakes and topcoat. Of course, my knowledge is 40 years old.

    1990 Mercury Black Max 175 2 stroke carb - trim pump is dead - need advice before proceeding

    The trim pump motor can be removed from the engine, after removing the PTT bolts and starboard side transom bracket. Usually it takes an Allen wrench to loosen the screws holding the PTT motor. The outboard motor can be trimmed down for this. Alternatively, you can remove the six bolts that...

    1979 Mercury 70 EL Thunderbolt Kill Switch Install

    It does not need to be very thick. 16 or 18ga probably works fine.

    Can you spray paint a prop?

    Gee, sand the prop, spray it with a self etching primer and then rattlecan enamel, of your favorite color. It will stay on the prop until you hit something.
