    Making engine beds

    Doesn't matter what ever you have, Its just a built up block of wood in the end. Don't overthink it the boat and driveline is less precisely built than one would think.

    Random Hole in the block 1998 4.3 Vortec

    It is for the dipstick tube but you may also have a dipstick that attaches to the oil pan, or at least the 4.3 I had with a cast pan did. In which case you can seal this off with a plug and rtv

    Idle issue 4.3 mercruiser LX

    sounds like the carb bowl is overflowing. That would be the result of a non functional needle and seat/ float or too high of a fuel pressure

    I noticed I had milky oil when I checked dipstick. Last thing I did was clean the riser and replaced gasket. It never overheated. Ughhh

    Quagga and Zebra mussels inspection on mercruiser out drive.

    The drives tend to get fairly hot when in use. Next time you are on a good long on plane run stop and put your hand on the upper or use an IR thermometer. I would bet the upper is around 180-200 F . I guess this is why they make drive showers

    Quagga and Zebra mussels inspection on mercruiser out drive.

    Yeah the water running through the drive cools it. If you run really hot water through it not only will the drive get hot but the same hot water wont cool the engine or exhaust very well. i understand what they are trying to do with invasive species but i would not let them do this to my engine
