    Default Marine Power Parts Sources?

    I recently purchased a 1995 Mainship with Marine Power 7.4L 370HP big blocks. They run fine but it has been 10 years since the risers were changed and I need to disassemble them and see if they need replacing. Does anyone know a good source of parts for these engines?
    They were described a "Frankenstein" engines with parts from Volvo, Crusader, etc and I have not located a good online source specific to these engines.
    Thank you
    Scott

    Ayuh,.... Exhaust manifolds, 'n risers are somewhat an industry standard type a thing,....

    Look to after market parts when in doubt,...
    Osco, 'n Barr are US built exhausts, a simple measurement of the riser bolt spacin' oughta get ya what ya need,...

    Just a friendly FYI.......
    Although we will often see an Elbow being called a Riser, these are actually Elbows.
    Risers/Spacers fit between the manifold and elbow.

    Post a few photos of your engine and exhaust system for us.
