    Mercruiser 470 Water Pump question

    So Spring is almost here and soon I will be working on the infamous water pump seal issue on my 470 (slight coolant leak from weep hole). Has anyone tried or heard of using an external pump (electric or mechanical) to eliminate this issue altogether with any success? Bad design having coolant...

    Mercruiser 470 Coolant Leak

    I have a 1987 Mercruiser 470 180HP (330 hrs. on motor) that leaks coolant from around the coolant reservoir cap if I have the reservoir full. If I keep the coolant level 1/2" or so below the filler neck it does not seem to leak. I have changed caps & cap gaskets and checked for any blockage to...

    Seasonal Engine Oil Change

    This past boating season I only logged about 5 hours of running time on my Mercruiser 470 due to repairs and weather issues that kept me off the water most of the season. Will I be doing any harm to the engine by not changing the engine oil before winter storage and run with this current oil...

    470 Alternator/Flywheel Removal

    I need to remove the alternator/flywheel from my 1987 180hp 470 in order to replace the water pump cover (a few of the mounting bolts are behind the flywheel). I discovered a broken tab on the water pump cover from the PO. It must have broken when he installed the upper bracket for the...

    Alpha One Shift Cable Replacement

    Carburetor Rebuild Question

    I have a 1987 Mercruiser 470 w/Rochester Quadrajet. The engine idle is inconsistent at times below 900 RPM(stalls ocasionally). Other than that the 470 runs great. Is it worth having the carb totally rebuilt in the off season or is there a simpler solution? One price I got from a local Marina...

    Mercruiser Engine Oil Weight- SAE40W vs SAE30W

    I have a 1987 Mercruiser 470 that I normally run straight SAE 40 oil during the boating season. Anyone have experience using SAE 30 in this motor during the summer months? I'm having a hard time finding SAE 40W. Is SAE 30 too light? I don't want to risk any engine damage because of a different...

    1987 Celebrity Steering Wheel

    Does anyone know what type of wood was used for the wood steering wheel trim on a 1987 Celebrity? I'd like to re-finish mine. I sanded one section and it doesn't seem to be teak like the rest of the trim on the boat.
