    Prepping Diamond Tread for Refinish Gelcoat

    it was in the 80's for temp. so after I globbed it on the tapped off area, I used a notched trowel to mush it around, then climbed off the boat, put the notched trowel in the bucket of acetone, went back on the boat, and used the roller to make the pattern. the roller flattened and pulled...

    NEED HELP QUICK PLS: Replacement Engine choices for 350 MPI

    since the motor is a salt water motor and was neglected. consider that the only thing salvagable will be the carburetor, front accessories, ignition, and rotating electrics. the block, heads, intake and exhaust manifolds are toast the other will not be far behind. however you will need to...

    NEED HELP QUICK PLS: Replacement Engine choices for 350 MPI

    its actually true. every motor in front of any sterndrive is standard left-hand rotation. right hand rotation motors were used on inboard applications only, and that requirement went away over 40 years ago. dont believe me, or @achris who is a trained mercruiser tech. maybe you should call...

    Engine starts to sputter/breakup/lose power after warm 3.0 ‘98

    i agree, most likely plugged anti siphon valve, or plugged pickup strainer, or plugged tank vent, or crud in the tank, or water in the tank, etc. all leading to the engine running horribly lean. when it does that, that detonation you hear is the pistons being eaten by pre-ignition detonation.

    Prepping Diamond Tread for Refinish Gelcoat

    I would sand it down and do your own non-skid. I used fumed silica to thicken the gel, rolled it on thick, then used a bed liner roller to make the texture. https://forums.iboats.com/threads/1988-rogue-2420.486013/page-9#post-3435737

    Plating, not the eating type

    any process where you learn something is a valuable experience, no mater what the outcome. remember, Edison did not fail 10,000 times building a light bulb. he simply learned 10,000 ways to not make a light bulb. rock on GM......rock on if successful, will you take donations to plate parts?

    Need help finding a HEI conversion distributor cap for prestolite

    HEI is GM's term for their "High-Energy-Ignition" coil-in-cap automotive distributor. truth is, all ignitions are high energy. however Matt is correct, they were NEVER used in a boat because as they came from GM, they were never tested for SAE 1171, nor were they available without vacuum...

    1979 omc sterndrive oil type

    being a 1979, it would be white, it would be a hydro-mechanical shift stringer 400. my guess this is a new to you purchase. please note that that drive was obsolete in 1980, replaced by the next obsolete drive that was from 1981-1985 if you havent done so yet, you may want to pull the drive...

    ENGINE REBUILD HELP

    pull your motor and take it to your local machine shop. you must first machine the block before you buy pistons, rings, etc. nothing special about a 4.3, however expect to pay about $1800 minimum to rebuild. I personally would go with a vortec block/heads which you can get for about the same...

    "86" Starcraft Floor Repair?

    is the starcraft aluminum or fiberglass. if aluminum, you would be OK to run with rotten floor, etc. although all that water will make it perform like crap. the aluminum is hull and ribs are the structure of the boat. however the transom relies on wood, so that may be an issue. however if...
