    1979 Mercury 80 HP Tach issues

    Mercury tachometers need +12VDC, ground and stator pulses to operate. Normally a MerControl will offer these via plug on the MerControl or via pigtails on the newer Mercury controls. The stator pulse is on either of the yellow wires that go to the rectifier. One of these should connect to a...

    2018 60HP Mercury outboard - lower end

    Gearcases have tight tolerances. These are set using shims behind the bearings. Some need special tools to make it correct, and if incorrect, the gears wear out quickly. Gearcases are also often hard to disassemble. Check out Sterndriveengineering.com (SEI.com) for a new replacement gearcase...

    After 21 years, it most likely has been replaced at least once. Is it still an OEM model?

    2018 60HP Mercury outboard - lower end

    Water in the gear oil will cause wear on the bearings. This will only show up when the motor is operating. This can lead to a wobble on the driveshaft or propshaft, which allows water to get past the seals.

    Stator from 80hp to use on 200hp

    A V6 will have two switchboxes. An 80HP motor will be one switchbox. Do you have the same number of switchbox wires?

    1989 Sea Ray 200 BR Interior rebuild and new layout

    Actually, IMO Outboards killed the I/O market due to the Maintenace required by the sterndrives. I/O blocks were cheaper due to mass production of the auto industry. Unfortunately, the OB motors had less and a lot less Maintenace requirements.

    Takes on water over the transom while loading and unloading

    Gee, I did not read the multiple posts. How about larger tires on the trailer.? That may raise it up enough Aso. put the trailer in the water slowly, straps off and see it rises.

    1988 mercruiser 5.0 alpha one

    My '88 MerCruiser 4.3LX had two fuel filters. One was a small paper cylinder that fit inside a housing that screwed into the carb. The other was a porous stone filter that fit on the top of the fuel pump, under a cover. You might check them. Maybe the one on the carb is partially clogged.

    1989 Sea Ray 200 BR Interior rebuild and new layout

    You can cover the plywood with marine vinyl. Use stainless steel staples and stretch the vinyl to make it fit nicely. It will look much better than a crummy glass job. A good glass job will need to be sanded very smooth and then gel coated, with the right shade of color. You probably would...

    1989 Sea Ray 200 BR Interior rebuild and new layout

    Your motor well needs proper ventilation, for the blower to work properly. Gas fumes are heavier than air, so make sure the "sucking" duct is under the lowest part of the bilge, usually the engine, so it can suck out the fumes.

    Engine water flow issue

    As Scott said, the water pump kits come with several gaskets. Some of those do not exactly match the ss wear plate, so make sure you used the correct ones. The water flow is from the gratings, thru the wearplate into the pump housing and then back down thru the wearplate and then out of...

    Engine water flow issue

    I had barnacles clog the water inlet in the outdrive on several occasions. You need to pull the water pump base and scrape 'em out. You should be able to look in the gratings and see if it is clear. On my '88 4.3LX, there was a pair of plastic balls and a spring in the thermostat housing...

    1980'ish black max 150 losing all power after running for 30 minutes

    If the primer bulb collapses, it will starve the engine of fuel, which can damage the engine. Put a hair dryer's hot air on the switchboxes and run her on a flusher. See if it dies. If not, the switchboxes are good. Just so you know, that motor will continue to run even if overheat is...

    Mercury 80 won't crank with plugs installed

    Gee, my guess was ruptured diaphragm in fuel pump. That allows gasoline to enter crankcase in 2 cycle engines. Glad it was resolved.

    Testing stator

    The other resistance test is from each stator wire to ground. Resistance should be infinite.

    Gee, is it full of gear oil? Prop spins in neutral? Sounds like a rusty bearing.

    Testing stator

    I am assuming the motor is a 60* V4. Battery charging coil is yellow and yellow/grey. The stator battery charging coils should have resistance of .185 ohms. You can get to these wires at the plug that goes to the water-cooled voltage regulator. Power coil and charge coil connect to powerpack...

    Testing stator

    The stator battery charging coils should have resistance of .185 ohms. the power coils should have 45-65 ohms resistance. All this is in the factory service manual.
