    You say 110 hp; at what rpms? And which PP? They are numbered according to inlet diameter; type 65 is 6,5 inch dia, 90 is 9,0 aso. Is your old one totally wrecked, ie a substantial part of blading missing or so? Otherwise, they are repairable. I have som 90 ies on the shelf here.

    For new spares, contact Vosper Thornycroft, Mr Brent Voce, +44 2392 5397 50.

    My pp jet is a 65 with 110 bhp at 5500 rpm.What i need is a larger impeller the engine is over revving and needs a larger impeller.The one i have is a 573,i think i need a 482. Would it be possible to exchange plus any cash difference.

    Sorry, no 65 impellers here. But if you can't localize any in GB, the one you have may be repitched. First check that there is nothing choking the inlet (plastic bags on grating, condomes on leading edges, nylon stockings around the shaft.......), plus check tip clearance. You run a gas engine I guess, what max revs (and what boat speed) d'yo get now?

    Also check for air leaks around transom seal and handhole cover,

    You'd be surprised to see what comes drifting to our waters with the west winds from, well you know where......
