    Stern Drive, Trilux and Prevale Sprayer

    You will get much better anti fouling protection if you brush (2 coats) on the trilux. Spraying is easy and looks nice, but the coverage is thin.

    Fuel water separator and fuel filter on 3L

    IMO, the clear racor filters do not give sufficient extra value to justify the additional cost. Plus, I seem to remember one of the plastic bowls was ruined by the sun, and leaked fuel.

    Fuel water separator and fuel filter on 3L

    Gee, in post 29 you complain about water in the fuel when you fill up. In post 33 you say the rain got into the tank. You have confused me.

    Lower unit oil -- water or not?

    Water is present, IMO. Let the mix settle and it might separate.

    Adding ignition kill switch and lanyard 96 Johnson 88

    If you do need to add a separate ign kill switch, just splice it into the black and black/white wires. To kill the ign, they need to be connected together. My OEM harness uses bullet connectors to connect to the ign switch. I would simply use some of those to make some "Y"s to splice in the...

    Adding ignition kill switch and lanyard 96 Johnson 88

    My '98 Johnny came with a lanyard that fits the factory ign switch. The ign key can be used with or without the lanyard, as the lanyard, when pulled, turns the ign off. Here is the OEM ign switch. If you have one, you can buy just the lanyard...

    Anchor line

    A couple of years ago I found 300' of 1/2" 3 strand on the intenet for $40. It along with 10' of chain, works real well on my 21 footer.

    Merc 75 4 cylinders, 2 carbs

    Gee, pick a service manual from the link below. Make sure the carb is correct, so you can rebuild it properly. Merc made many motors with the same pistons, cylinders and ign systems. The carbs were different. Most everything else was the same for a long time. Your motor was made when...

    The Maxrules website shows it to be a 1992, based upon your serial number. They also show the mariner and Mercury models to be identical, except for paint.

    Fogging with 10W30 oil

    4 cycle multi-vis detergent motor oils have metallic additives. Metallic additives are not good for combustion in engines. That is why they are NOT mixed with gasoline for 2 cycle motors. 2 cycle oil or non detergent straight weight motor oil (if you can find it) is acceptable to fog or oil...

    Fuel water separator and fuel filter on 3L

    You might want to find a gasoline station without water in it's fuel. I have never had more than an oz of water in my water separator for my 63G fuel tank, at the end of the season. Try to stick with high volume gasoline stations, as they have the freshest fuel.

    Alpha One Stern Drive Trim Fluid Flush/Fill

    A lot of those reservoirs unbolt from the pump, with a single bolt on the bottom. It will drain right into your bilge, or hopefully a catch basin.

    1993 mariner od160931

    Gee, I sent you the manual link. Why not match up your motor with the info in the manual? The motor does not know it is grey and a Mariner.

    Gee, there is this manual in that group I sent. May not be the exact year, but likely close enough https://www.manualslib.com/manual/814763/Mercury-6.html

    Merc 75 4 cylinders, 2 carbs

    Replace impeller, wearplate and the two gaskets that sandwich the wearplate. Inspect the upper pump body for scratches in the stainless steel cup. Replace upper pump if you find that. Inspect the pump base for melting or other defect, and replace it if that is found. Often the pump base...

    You can buy self stick foam weatherstripping. Some of it is 3/8" thick, which could cover the screws.

    1977 Merc 500 water in oil

    You need to see where the gearcase is leaking. In my experience, most leaks on a motor of that vintage is the driveshaft seal. So if you can, use the gear lube pump tube to pressurize the gearcase. with a few PSI, and see where it leaks. Replacing the driveshaft seal is best by buying a new...

    Fuel water Separators ,Why not universal fit?????

    Mercury OB, MerCruiser and Yamaha (all small thread) interchange. OMC OBs use the larger thread. Since I have one Merc OB and one Johnny OB, I installed a Merc one on my Johnny OB, so I only needed to buy one kind of filter for both kinds of motors. To add to your rant, Mercury OB, MerCruiser...

    Mercury Gen 1 cables to OMC possible?

    You should check the travel direction on the MerCruiser throttle cables, as they may be different than the Merc OBs. I cannot remember how my MerCruiser worked, after all these years. Travel on the shift cable is real important, and I think Merc built in more travel than the OMC, do to the...

    Trim motor

    Actually it depends on whether the PTT motor is a 2 wire or 3 wire motor. Three wire motors use solenoids to provide power to either the green or blue wires. A center-winding ground completes either the up or down circuit. The non-energized solenoid is open. 2 wire PTT motors use relays...
