    Leaking fuel tank

    You could buy a new connector and put it on the fitting when not using the tank. Simply plug the fuel nipple on the new connector. That could seal the tank. Pop it off and connect the fuel line when you want to use the fuel in the tank.

    MerCruiser 5.0 (Carb Engine) will not turn, what is this part?

    Gee, will it turn over with the spark plugs removed, using a wrench on the main pulley? Fire extinguisher dry chemical is both course and caustic to metal. If the carb sucked some of it in, or some went into the exhaust port, it could be gumming up the works.

    Leaking fuel tank

    It is "leaking" from the place where the fuel comes out. When you connect the fuel line, that plunger unseals the tank, allowing the fuel to flow into the fuel line. I do not know if there are repair kits for the fitting itself.

    Battery disconnect while running engine

    OK, the voltage seems OK. It still makes sense to put a voltmeter on the battery and check for AC voltage there. Some of the alternator diodes could be shorted.

    Toyota/Lexus Timing Belt Change Thoughts

    So, you are going to let your kid drive a car with 150K miles w/o checking the brakes and wheel bearings? If you are in the rust belt, a visual check of the suspension and suspension support structures is in order, IMO.

    Battery disconnect while running engine

    I would check the alternator, as the diodes usually blow when the battery is disconnected. It should be as simple as checking for AC voltage at the battery when the engine is running. If no AC voltage, check for DC voltage rise as RPM increases, to confirm alternator is charging.

    Fast idle/start

    I am not an expert on your motor, but my '98 Johnny developed a situation where the linkage stuck. I exercised it and it was fine after that. You might like to see if it needs lube.

    Trailer Painting

    Out here on the salt pond, powder coated steel lasts just a bit longer than painted steel. Neither are practical, IMO. Outside stuff needs to be hot dip galvanized, aluminum or stainless. HD galvanized needs any suspect spots promptly painted with the cold zinc spray. I use a couple of...

    Toyota/Lexus Timing Belt Change Thoughts

    Gee, I am not sure of the question/dilemma. You bought a used car with a lot of miles and don't know the maintenance history. I would get a service manual and see what maintenance needed to be performed. Some stuff you can check at least casually like oil and fluid levels. I would change the...

    1992 johnson faststrike 150

    Overheating will activate the S.L.O.W system which limits RPM, but should not stall or otherwise shut down the motor. That motor should have the shift assist switch which kills spark to 3 cylinders. Perhaps the shift assist switch is activated and then S.L.O.W. then causes the engine to...

    Are you sure the alarm is for overheat? 150*F is not overheating, as thermostats are 143*F. In addition, your motor may have a fuel restriction alarm on it as well as overheat alarm, plus the oil low alarm.

    Trailer Painting

    How old is this trailer? I will assume you boat in freshwater, or just use the trailer twice a season, and slip the boat? Sandblast and then prime is best, but wire brush off the loose rust and prime those areas with rusty metal primer is pretty good. Brush on a nice oil based topcoat and you...

    Covering Built-in Fuel Tank?

    I have a hatch over the tank sender, however, the anti-siphon valve, fuel line and vent lines occasionally need maintenance. The hatch is not near any of those. The tank has a full cover secured by 8 or 10 screws and is caulked. The bilge drain runs under the fuel tank, so any water that...

    Covering Built-in Fuel Tank?

    Gee, make the tank hatch out of dry 1/2 pressure treated plywood, and seal it with poly resin. If it needs more strength, see if you can use 5/8" plywood. It should last 10+ years.

    Ignition switch

    Does it have a distributor? It doesn't reeally matter as Merc harnesses work for both distributor ign or ADi ignition, but useful to know for troubleshooting. Wire colors on that old Merc should be: White - ign power red- battery +12VDC Yellow-starter solenoid power- goes thru neutral safety...

    Mercury 50HP 4S won't crank

    Gee, I never saw one break. They are located inside the MerControl. A lug on the MerControl linkage closes the switch, allowing them to connect power to the starter solenoid, when in neutral. Maybe a wire to them broke?
