    Default Where are the timing Marks on Marine Power 5.7

    I have a new marine power 5.7 carburated engine. Manual says to check timing at 8 deg at idle. I do not see any timing marks on the engine. I see the line on the harmonic balancer but I do not see a plate with numbers as the drawing in the book shows.

    Anyone know what I might be missing?

    Could this be intended for flywheel timing?
    Look at the rear of the engine and at the flywheel cover.
    You may have an open port (w/ a timing tab) that leads into the outer area of the flywheel, in which case the flywheel may be marked off for ignition timing.

    If not.... then you'll need an add-on timing tab at the timing chain cover.
    The problem is....... you may also want to perform a PPS (positive piston stop) to verify your new TDC markings.


    BTW, look up your Total Advance specs. After you set BASE advance, do a dynamic test/check at 3.2k rpm or so.
    This is to verify your progressive and total advance.


    IMO, setting BASE only, and then walking away is not wise.

    you need a timing tab...I'd call the distributor you obtained the engine from and tell them you want it installed, properly, to maintain your warranty...
