    351 engine only runs at 30 degrees BTDC

    The 1987 Subra I just purchased had an engine rebuild before it was sold to me. I have to set ignition timing at 30 degrees BTDC for it to run. It seems smooth and responsive when I throttle with no load. A friend suspects timing gears may be out of sync by a tooth. Compression shows between...

    Inboard wire from drive box

    I just purchased an 87 Supra with 351 engine inboard. There is a wire coming from a terminal on the drive box that is not connected to anything. What is it and where should it connect? Thanks.

    Need a new Prop?

    Just got my 1989 Celebrity 182 4.3 l running this season with an engine rebuild. I have not pushed it above 4000 rpm but am only getting about 25 mph at that engine speed. My prop is a 14 x 19 pitch aluminum. Will I need to re-prop to get a little more speed? If so, what is recommended? THanks.

    Mercruiser 4.3 1989 Compression

    I purchased this boat with no history except that it would not start. After going through the systematic troubleshooting, I found that the compression in the cylinders was 80-90 psi and adding oil to a cylinder increased compression to 120. My question is...is 80 psi compression too low for the...
