typical prop slip?

[1fife]

i have seen the prop Q calculators

but what is a typical prop slip?

ive heard people say as low as 4 and as high as 20

how can this be ajusted at top speed, i realize with pvs how to do it in holeshot

Here is my experience:
7-15%
What seems to increase slip is, weight of boat, weight in the boat,hull resistance (fiberglass vs. riveted alum>) hand the steepness of the dead rise in the transom.

Propeller cupping seems to decrease the slip.

Example: an welded aluminum jon boat that weighs 250lbs and has one passenger and 1/2 tank of gas will have a low slip.

Good luck
