    Volvo Penta aq125a

    check if the voltage to the coil is 12 volts or 9 volts when running (should be 9) what is the dwell angle (points)? having a bad condensor would also act the same way.

    2bl vs 4bl

    you are overly protective. Marine motors are designed to be run at WOT for hours.

(Volvo ran 715cfm vacuum secondary props for their 275hp and 310hp V8's for years). however those motors had a slightly different cam and heads than the typical mercruiser. a spread-bore is slightly better than a square bore for the average...
