    Pre-Alpha "R" outdrive main bellow replacement

    The backyard "supermechanic" *sarcasm* that I bought my 79 Doral off of stored the boat one winter with the motor trimmed up. Well.... you guessed it... a critter chewed through the main Bellow. So he replaced the bellows but evidently didn't have the spreader tool and the ridge inside the...

    i think i have a re-assembly problem

    Changed the water pump impeller on my 79 mercruiser 165 hp with Mercruiser 1 drive. When I put the upper and lowe drive halves back together there was about a 1/16 inch gap between the two pcs. As I was dropping the top down onto the bottom I turned the shaft and felt it drop into place but no...

    bellow leak a bit confusing

    When my boat started leaking I had to check my bellows. When I pulled the drive off I noticed the u-joint bellow had water in it and the gimbal bearing was rusted. My hinge pin tool finally came in so today I removed the bell housing and bellows. I took special care removing the bellows to...

    still trying to troubleshoot leak

    Today I dumped the boat in the water and it is definately leaking through the transom assembly somewhere. A constant trickle at about 1 cup of water every few min. This is with the engine shut off. I looked at the bellows as best I could utilizing a telescopic LED and telescopic dentistry type...

    leaky transom plug

    Just curious. My transom plug was leaking via the bolt through the middle. I'd say when I filled up the bilge with water it was dripping a drop about every 3 seconds. Now my question is.... when the boat is in the water is it possible that with the added water pressure a drip like that could let...

    boat taking on too much water

    Hi. My boat has recently started taking on about 2-3 gallons of water per day. I notice that there are two rubbers between the transom and the outdrive. One large one which I'm guessing is the main seal and another below it which is longer to allow for more movement and is about 3" in diameter...

    Alternator output wire?

    Tomorrow I plan on installing my second battery and battery isolator along with my 1100 watt stereo to get them musky riled up. I've been looking through the service manual. Am I correct in assuming that the orange wire at the battery is my alternator output wire to charge the battery? (Assuming...

    79 165hp stalls under load

    I've made a couple other posts on my "issues" however as symptoms have become more clear I figured I'd start another post. 1979 Mercruiser 165hp in line 6 cyl. Initially, the boat seemed to be stalling and not re-starting once it got warm. So this morning I bought a new coil for it. Fired it...

    79 mercruiser 165 hp coil resistance?

    As I'm broken down on the lake and not at home to check service manual, I was hoping someone could tell me what proper resistance should be for the coil on this motor. I don't want to spend money on parts if I don't need them. Also, on a coil that's going bad, will it give a bad resistance...

    79 165hp 6cyl dying when warm

    Let me start by saying I'm not in danger and a nice fellow has offered me his dock and a ride home. But when my 79 165 hp warms up it dies. Not overheating. Got fuel in the lines. When I turn the key its firing briefly. A sputter. So I have spark. But I'd rather not have to come back tomorrow to...
