prop selection for WOT

[NoBones]

My 1970 20SF has a 97 Carbed 200HP Merc. 21 inch LaserII
prop. 24 inch Bennett tabs and 80 gallon tank. By myself
the hole shot and top end is great. Top speed 62mph on the
GPS at 5800rpm. (My engine has been tricked out) If I put three of my 250lb buddies in the boat, hole shot and top speed drops off real bad. Solution: 4 blade prop for those times when I run a heavy load. Top speed is around 55mph 5800 rpm(with 4 big guys in the boat) But my hole shot is far better, not quite as good with the 3 blade by myself, but it works. Hope this helps.
See ya, Ken
