    Trim pump seal

    77 1150. Short of getting a full rebuild kit for a trim pump that works great, what would you use to replace a reservoir seal? A big o-ring? Rtv cement? Something else? I’ve had to refill mine a few times this year already.

    Merc in-line 6 distributor bearings

    Im looking for dimensions of the distributor bearings. I have a 77 1150. I believe a 15x28x7mm will work. I’d like to get it ordered before taking apart the unit... otherwise I’d take calipers to it and measure... anyone know the size or have one around you can measure? $50 for a $5-10 bearing...

    77 1150 Orange wire

    I was hooking the tach wire to my rectifier for an aftermarket unit, no problem but I realized there’s this orphaned orange wire. Its connector is tapped so it’s never been hooked up. The engine runs, starts stops. So I’m stumped. On a wiring diagram I see the external harness has an Orange...

    1150 timing(distributor recently rebuilt)

    Throttle at idle this is where #1 sparks. I can’t seem to make up a fraction of that distance with the adjustment screw. I’m thinking I need tonset it where it should spark, pull off the belt, align and put back on. (Distributor recently rebuilt and all markings were aligned)

    stubborn start '74 merc 1150

    I got my carbs not flooding and cleaned, new floats. I noticed It's hard to get going at first. I just inherited the boat, but I recall it taking a while to start when cold but then when warmed up it's good. Testing, I blew some air through the tube to the main jet on each carb, to get the...

    Merc 1150 throttle

    Is this normal? When I push the shifter back the throttle moves immediately, as expected, from closed to fully open. Using the idle lever or moving the control to forward, it shifts fine but doesn’t appear to move the throttle cable until I’m over halfway forward, it opens 100% as well. Seems...
