    How long do bellows last?

    5 years for oem in fresh water trailered is reasonable . More than that is borrowed time . Worse conditions ide say less time. Even so you should go through the drive every 5 years to inspect corrosion and what not.

    Time for my first bellow change, tips?

    Buy oem and don’t use the exhaust bellows. Trust me once you finish the job and realize how hard it is , you’ll be glad you bought expensive parts . Run the updated exhaust tube that slips in and out when drive goes up and down. I fought that damn exhaust bellows for hours for it to just fall...

    Bravo 1 vs 3 gimbal housing ?

    I’m bought this bravo 3 gimbal housing because my bravo 1 has corrosion on the water inlet . I was told by some people on a fb group they are basically the same. Now that I have them side by side there are some extra holes and missing threaded holes I circled in the picture. Not even sure what...

    Aftermarket stainless upper gimbal pin?

    Idk if it leaked but pitting plus destroyed seal leads me to believe it did leak. I’ve never put this boat in the water. It’s getting drive all freshened up and a new engine so I’ll know once I dunk it for the first time. I ended up ordering hill one. I’ll update once it arrives and see how...

    Aftermarket stainless upper gimbal pin?

    I am rebuilding/painting everything on my bravo 1 while it’s apart for a new engine . I tore down the gimbal assembly and inspected the upper steering pin. It has pitting where the seal rides. Good thing I did tear it down because seal was also destroyed. . I did more research than I care to...

    Working on a mid 90s omc cobra drive with 5.0 efi engine . It only has one shift cable and I bought a replacement cable but it’s not right on the drive end. This boat has a hose that runs up from the transom with the cable inside and then cable goes directly to shifter. No bracket or “lower...

    Merc 4.3 mechanical fuel pump oil leak

    Tried fipg made by Toyota. Thst stuff has never let me down. Going to try and run the boat again at the lake today. Worst case I’ll buy a new pump. I noticed mercruiser stopped using USA carter and uses a Korean brand now. I’m thinking if this doesn’t fix it the pump casting is leaking or maybe...

    Merc 4.3 mechanical fuel pump oil leak

    My 89 merc 4.3 v6 carbureted fuel pump leaks oil. I replaced the pump a year ago with a carter USA made marine fuel pump and just noticed it started leaking oil . I pulled the pump and replaced both the plate and mounting gaskets and it still leaks. Seems to only leak when I put a load on the...

    Mercruser alpha 1 gen 1 stern drive issues

    What do you mean kick water? Pretty simple system . Impeller pumps water to the upper half of the drive . Goes into the hole in the bell housing , a rubber hose feeds it to the transom and then it pumps into the thermostat area to feed the engine. Usually through an oil cooler or power steering...

    Alpha 1 lower shift pin fell out

    Sweet thank you! I’ll get that ordered and a new screw/pin . Had to drill it out since it was seized in there. It did last since 1990 with almost 1000 hours . Probably did 10s of thousands of shifts lol . Sucks it didn’t break when I did the lower cable a few years back. Super easy to pull the...

    4.3l mercarb rebuild hard restart

    So yesterday I rebuilt my mercarb (4.3 v6 1989 engine) after dealing with the way it ran for years! Needless to say I should have done it years ago. Boat has always had an off idle roughness and hated running between 1200-1800 rpm. I found some passage ways dirty. Anyways got the carb together...

I did some more looking around for a better price and found...
