just another prop question

[fishingman220]

I have a 22ft proline, 5.7 with alpha1 when it is me and my wife, it jumps up on plane fast and runs about 42 but turns 5100, when i have 3 or 4 fishing buddies, it takes alittle longer to get up, and runs about 38-40, and turns 4800, both at WOT, i have a mercury vengenance 13.5X19 prop. i would really like to pick up some top end, is there anything i can do other than trying to build some more power and then go to 21 or 23, or can i go bigger now???

Re: just another prop question

A 21 should give you "about" 4,700. Would make your hole shot a little weaker
might give you a little more speed.You should stick with same brand and material to keep performance along the norm.

well the top on the motor says redline or WOT should be 4400-4600, so shouldnt i give it even more prop????

Re: just another prop question

hole shot doesnt really bother me as long as it doesnt take 1/2 a mile to get on plane. the boat weighs around 3500, maybe 4000 fully loaded for a day of fishing

A 23 would put you at "about" 4,300 4,000 with your buddies and a further reduced hole shot.Too low in my opinion.Keep in mind these figures are not carved in stone could vary in either direction.If you can exchange the prop try a 22 if you can find one or a 23.You could have a prop repitched up or down a little, the less the better.Personally I would try the 21 if it turns up too much repitch or stay below the rpm.A 23 probably would struggle with your buddies aboard.Is your present prop in excellent shape?

a couple small nicks, but over all good shape.

Re: just another prop question

Go to the propfinder in Iboat, I think you will find that the recommended prop is greater in diameter that what you presently have. Not a lot but it could make the difference in the amount of energy transfered to the water and get you that quicker on plane and lower the rpm both. Perhaps a 4 blade with such a heavy combo would be a good thought.
