    Starter bolt snapped

    One of the starter bolts loosened and snapped the other on my 4.3L Mercruiser. This is the bolt closest to the block,it's recessed about a 16th inch and since the opening faces down towards the bilge it isn't easy to access. I took off the riser and exhaust but still can't work very easily...

After a few minutes it stalled and it has been 2 weeks now still no luck starting it. Does not sputter...

    1963 Johnson 3hp carburetor floods

    I rebuilt the carburetor except the float which seems fine. I even had it running at one point quite well under this condition but it keeps flooding while trying to start up. There is gas just pouring out of the intake. I assume your going to tell me to try the replacing the float but is there...

    Got my little motor running after a bit of maintenance, had not been used in over 25 years and it overheated.

    Aligning coupler and drive shaft splines.

    Latest in the saga of getting my boat ready for summer... I had to replace the exhaust manifolds and decided while waiting on stern drive parts to test the engine. Now the drive shaft spines do not line up as the coupler position has moved. How do I re-align the coupler or drive shaft? I can't...

    I recently removed my gimbal bearing and though there is a grease fitting on the housing, I noticed the bearing itself was a curvedrounded steel with no access to the inner bearing.

    which grease where...

    My new gimbal bearing had NLGI #2 grease only stamped on the box but the 2-4-c(NLGI) container states "for gimbals, and splines use quicksilver extreme'. Also, I believe a mechanic told me to not use the spline grease for the splines. I need to grease both the splines and gimbal, I have both...

    No Oil pressure after changing oil.

    I am trying to winterize my 1999 sea ray 190 4.3L for the first time and tried using a JABSCO drill pump to pull the oil from the dip stick tube. This comes with a smaller diameter tube to snake down into the pan and it didn't work too well. After completing the oil change my engine is not...
