  • Coolant and sea water flow

    Working on installing reinstalling 2nd Volvo Penta AQAD 40B, now in place and aligned, trying to find information on flow, I have two manifold coming up from bottom, 1 has 4 4" fittings (for main engines?) and 2nd has 2 1 1/2" fittings (for gen set?).
    Engine room also has small generator.
    Would also like information on how to set up to run on shore.

    The info on the motor is in the service manuals

    Running a genny on the hard requires pumping water (more than a hose)

      You need one of these (always reminds me of a toilet plunger) https://www.iboats.com/shop/seadog-m...h-inboard.html
      It goes over the underside of the through hull fitting and jams against the ground to stay in place. Hook a garden hose up to it and you're good to go.
      It will work on either the engine or the gen set.
