    pump vein housing

    this came out of my GPR SHO conversion, I see it right know it's going to be an expensive year trying to keep a pump vein housing to last on my GPR.

    Looks like it. Tripples are where bad on the veins but looks like conversions are even worse ! Maybe space the prop more forward ??

    Looks like the 8 vein stainless is going to become mandatory on these hi horsepower combos..

    Why not cure the cavitation with a 160 mm setup? Poor mans setup would just require a 160mm liner and prop.

    A 160 liner and prop is not going to do a thing for my set up.

    50 thousands set back there in not a lot of setback, I am running over 100 setback on my SHO.

    Is it just me or are there only half of the veins eroded from caviatation? I only ask this as I think I saw this on SHUDude's conversion pump also.

    Couple questions Jim--why couldn't a 160mm setup solve your cavitation and which direction are you looking at???

    A B1 FZ will cavitate some with 160mm liner, an E1 gets blown away with a 160mm. And these FZ's have huge intake openings, the GP's have a tiny opening which makes it even worse.
