    Having Charging and Tach Problems???

    Well, this 1975 Glastron came originally with a 1973, 150hp Mercury, with a "Trigger" ignition (with distributer). I have put a 1981 HP Mercury with the newer style ignition. From day 1 (last year) the tachometer never worked. When you turn the key on the tack goes to 2K and when started the...

    Engine Wiring - Won't charge battery

    Well here are 2 pics of a powerhead I switched onto a Mercury 85hp frame. I believe it is a late 70's /early 80's Mariner. 80hp - 4cyl. Runs great, but probably needs a new engine wiring harness. However there is a broken wire and the battery won't charge. Can someone tell me exactly where...

    Rebuilding Merc Wiring Harness

    I have repaired, cracked INTERNAL Wiring harnesses in the past. I have typically "peeled" each wire back as close to the connector as possible. Then I would solder in new wires, braiding them together, not twisting them together. Next I would "goop" each wire with Liquid Black Tape. Then...

    1997 Force Trims down, not up??

    I have a friend with a Force engine, with trim. Aside from problems with the switch, is there a reason why trim would not go up. That is to say the trim pump/motor doesn't run in up position? I am asuming there is either a double pole /double though switch that reverses the motor or some...

    Can't take my hand off the throttle!!!!

    Well, I recently swapped the power head from my 1973 trigger 85hp, to an 80hp 1979 Merc Mariner. Nice motor. Runs top notch but, I am using the 1973 Mercontrol ( which looks identical to the Mariner Control) and when I release the throttle control I back down to 5 MPH. My mechanic says you...

Serial # is 5144775, 80hp. anyone know what year this is?? Motor runs pretty good but seems to starve for fuel over 30 MPH, I am suspecting the fuel...

    How to set timing on 1973 85HP?

    I have just installed a used distributor, in my 85hp Merc. I am awaiting a manual, and was wondering if someone could explain the base timing setting. The tag on the side of the motor says .172 BTDC , 27degrees. I see the gradations on the side of the motor. There is also an arrow on the top of...

    Throttle Adjustments

    I have a 1973 85hp Merc. Does anyone have instructions for adjusting the "Idle", "Starting" and "throttle Stop" screws. I guess that Starting is max for the warm-up lever, and idle is obviously with warm-up off, and throttle is "maximum-open", but I am having trouble where I adjust in the...

    Loss of power on the Top End??

    Have a 1973 85HP Merc. I have tested 3 times running 6 gallons of gas thru it. Engine ran flawless (cept for the R shift problem in another post). Reved to 4,600 RPMs and got my 17" tri hull to 37MPH. Never rode the motor hard, always backing to 2/3 throttle. I like to run at 3,200 rpm and 30...

    Reverse Just "Clicks" ???

    Well, I had an earlier post on what I think is a "slight bent" shift shaft. I added an extension bracket (see pic), and 1) tested carefully, while rotating shaft, adjusted to get BOTH F and R. R FIRMLY LOCKS INTO GEAR, in BOTH DIRECTIONS. Then put the muffs on, and tested. Slides right into...

    Cheap fix for shifting problems "73 Merc 85HP

    I had an earlier post, common conscenous was the shaft was bent and the engine needed to be disassembled to allow shifting to reverse. The motor would shift to F but the shaft was bent slightly and would not go into R. Well, I guess is this is kind of "Rube Goldberg" but I was really struggling...
