    Mercury Gen 1 cables to OMC possible?

    Merc OBs and OMC move their throttle cables differently. OMCs usually push the throttle open, while Merc OBs push the throttle closed. Some controls have places to attach the cables for both functions. They are therefore universal. if you do not have a universal control, I fear adapting...

    Quick Question for Merc Experts

    Generally too lean a mixture will cause the motor to bog when trying to accelerate. If she doesn't bog, and idles reasonably well, the idle mixture is fine. Mercs of your type will idle a bit faster when the idle mixture is too lean, but not a lot faster, mostly just smoother. They usually...

    How is HP selected on old Elgin Outboards?

    I saw a utube video where a guy ran a 1957 Elgin 12HP, in 5HP, 7.5HP and 12HP "modes". The selection of power was via a keyswitch on the motor. How is this accomplished? RPM limiter? Cylinder deactivation?

    1976 mercury 40hp flywheel question

    Make sure the ring of small bolts around the large flywheel bolt are tight. Sometimes they need Loctite to stay that way.

    Fuel water separator and fuel filter on 3L

    If you have a lot of water in the fuel tank and the boat is trailered, you can usually pull the fuel gauge sender and stick one of those "shake-shake" Siphons in it. Put a piece of 1/2" copper on the free end of the siphon hose and stick it thru the garboard drain hole. Now use a funnel and...

    Nissan or Mercury?

    Gee, even large 25 year old 2 cycle outboards do not foul plugs anymore. My '98 Johnny 150HPV6 (2 cycle oil injection) will troll all day w/o issue. Not sure what the issue is with your Honda.

    Fuel water separator and fuel filter on 3L

    You realize that water separators work by gravity, right? Fuel and water goes in the top of the separator, and the water settles to the bottom, as fuel is drawn from the top of the separator. The filter element does nothing to separate the water from the fuel. A water separator with no...

    Merc 75 4 cylinders, 2 carbs

    Most Mercs have a piece of plastic that flips to release the throttle cable. The idle stop set screw is usually on the bottom of the throttle arm. You usually back it off to lower the idle and adjust the barrel on the throttle cable to push the throttle closed.

    Boat floor

    The plywood will be sealed on all sides with poly resin, right? Why not overlap the seam with the vinyl? It will give a smooth look, if the seam is smooth.

    Crack in cylinder wall, need insight....

    Gee, I vote for welding it from the outside. Also, the crack was likely from overheat, so you must make sure that does not happen again. There are no ridges in the bore, right? Causes of overheat are lean fuel/air mix, water pump issues, thermostat issues, over advanced timing and poor fuel...

    Merc 75 4 cylinders, 2 carbs

    The idle speed is controlled by the idle stop screw, on the throttle arm. Of course, the throttle cable pushes against the idle stop screw. So turn the idle stop screw to lower the idle speed. It will push against the throttle cable. If the push is too much, turn the barrel nut on the...

    yamaha 2013 waverunner

    I believe those models have a self check like an auto OBD-II system. You hold the button on the bottom left of the dashboard down until the code appears. Hopefully the code is listed on the internet. Remember those WR motors have most of the components of a modern auto, like crank angle...
