Prop Help

[Tre_Hart]

My friend has a 2009 Procraft 19' with a 150 merc optimax. He currently running a 19" three blade prop (not sure what make) but he's looking for a little more top end speed. Should he go to a bigger pitch 4 blade or stay with a three blade? He doesn't want to lose his hole shot either. Any suggestions would be greatly appreciated.

LOL...IF I had a dime for every guy that wants more speed without sacrificing hole shot with a 150hp.......lol.
answer.....NO AND NO AND NO!
21"THREE BLADE MAY NET 1-2 MPH BUT WILL DEF HURT HOLESHOT ...YOU ONLY GOT 150 HP.
4-BLADE =SLOWER TOP END.
A GOOD PERFORMANCE 19" PITCH STAINLESS MAY BE THE ONLY CHOICE.....BUT WITHOUT THE INFO ON THE PROP HE USING AND RPM AT W.O.T........ IT IS WHAT IT IS.
