    Yea the fwd third of the clean out hand hold is even with the transom.

    We just have to pull the transom cover to drill and tap. I thought about doing it before we reassembled, but if I had there would have only been one tapped port. And in the wrong spot.

    So did you find out if we can try the impeller before we buy it? Or how much he wants for it?

    250 for the impellor, he wants to just sell it outright to pay me back for the aeromotive pump i bought him this mornin if you're currently runnin a b-cut, this mpd impellor will feel and bite like a small a-cut or ab. he turned it 7800 with about 1400hp(blown 540 with a 250hp shot)

    I was also told by someone in the biz. that the fittings need to have a small keen hole! For good accurate readings. Fill the fittings with JB weld or bondo and drill a 1/64" or a 1/32" hole through the filler! This is because the fitting might not be stright with the water flow through the housing and may act as an evac causing it to suck on the fitting port! Thus not accurate reading! FWIW! WT

    "Knowledge is power" the effective way to add ,subtract or change "hardware and setups" is with feed back
