    MerControl Help Please

    You should be able to reassemble no matter where the shift and throttle cables are set. Simply move the throttle arm until the "knobs" fit into the groove on the wheel shaped casting. Disconnect the cables at the engine if necessary. Watch out not to lose the small cylinder that helps hold...

    Trailer axle capacity/sizing

    A trailer for a 3500# boat will need to have a larger capacity, as the trailer itself weighs 600-700#. When I looked at trailers 4 or so years ago, a trailer for a 3500# boat was usually dual axle, with a capacity of about 4400#. You might want to double check the weight capacity of your...

    Fuel Tank F Up

    You motor will not have an issue puling fuel thru the larger dia fuel line. Replace the fuel line with the correct dia hose or get a proper reducer for the tank. Normally idle mixture needs to be set on the water under load. Flusher devices do not provide the backpresure or load of a water...

    Serial number means ...?

    Watch for quality. You have an obscure motor with a regular maint item, and the only one who had it was from the PRC? It sounds fishy. As an example, I bought some spark plugs from the Chinese, and even though it was a sorta normal part, the spark plugs I got lasted 300 miles, until they...

    CHARGING QUESTION

    That voltage is too high. Check the connections to the battery, as the battery functions as a voltage regulator, via it's load on the circuit.

    Serial number means ...?

    Sears may still sell parts for that motor. You might check there. A lawn mower shop (if there are any left) may also be a source, due to the OEM playing mostly in the mower industry. Some of those motors had a balloon-like fuel pumps. You might see if you can source one of those, if necessary.

    Any saving the engine? I’m devastated

    Gee, I lost the thread. Why do you want to add tranny fluid, Kroll, pearl oil, Marvel Mystery oil or something to the fuel? At this point if there is any rust on the steel parts, the damage is done. Also, MMO is made to be burned, but I am not sure about the tranny fluid, Pearl Oil or...

    Painting Prep for One part paint over gel coat

    There used to be a paint product exactly for that purpose. It was dull dead grass or something like that, made by Pettit. It was likely enamel as polyurethane paint wasn't invented way back them. As for Brightside, the label will instruct that no primer is needed over gel coat in good...

    1979 70 hp choke issues

    The carb shouldn't leak fuel, unless tilted up. I have not worked on those carbs, so I am not sure how the levers look. My sidebowl carbs have two levers, that work together to control the inlet needle. The straight one contacts the float, with the other one under it. Perhaps a service...

    Adding A Stern Mounted Trim Switch

    I assume the switch will be accessible when you are in the water, or standing next to the boat on it's trailer? If not, you should consider that, as that is the most often time I would use it. Any marine SPDT switch of at least 5A should work. $55 seems a bit high for a switch, but WM thinks...

    Gee, put the starter in the oven for 45 min at 250*F. No disassembly needed for fresh water.

    What size Fuel Water Separator? 1998 Mercury Force 120 HP.

    Gee, the metal water separator canisters do not rust in my speedboat, where everything else does. I have never had one collapse. Install them hand tight only. Using a tool on them scratches the paint, and then they can rust. Usually you can get them off by hand, but a std oil filter wrench...

    Outdrive Paint & Prep

    You want the epoxy putty to be applied to bare metal. Sand the OD, wipe with acetone and then quickly apply the putty. After it sets, sand smooth and prime with zinc chromate or etching primer.

    Any saving the engine? I’m devastated

    Gee, I dropped a Fat Fifty in warm saltwater, while running on plane. She was under water for 60 hrs, until I found her. I hosed her down and pulled the carb, distributor and starter, baking the latter two in the oven for 45 minutes on 250*F. I squirted some heavy gas/oil mix into the...

    brass propeller Johnson?

    When did spline drive appear on Johnnyrudes? Mid 70's? Earlier motors were pin drive, I would think. Are you sure that is not an inboard sailboat prop?

    Hydraulic steering is real smooth. If it springs a leak, it can get dangerous.

    What size Fuel Water Separator? 1998 Mercury Force 120 HP.

    Any of the screw on oil filter like water separators will work. You want at least a 5/16" fuel line fitting, but 3/8" is best. The Racor's with the clear bowl are nice, but are more expensive, have two gaskets that can leak, and will deteriorate is left in the sun. I use the cheaper metal...
