finding the right prop

[eggsuckindog]

Since it is at all trim angles your choice would be to lower the engine 1 hole or look for a prop that has more rake - basically longer sweeping blades

look at this pic and pay attention to the blade design

my previous prop acted the same as yours, could not trim at all without it blowing out, although no cavatation except trying to trim it. It was a standard Merc prop similar to a Vengence - rounded blades kinda like mickey mouse ears

The Stilletto I have now is another hole higher and I can't get it blow out at all - careful on RPM, a prop like that will knock off 200/300 RPM per same size

On another note - when looking at them recently they are priced at $250 new which I thought very reasonable with prices I have seen
