best prop for 2003 2400 scr

[dlilly]

my 2400 SCR with 5 adults can't make plane. What is the best prop option?

it depends on which engine/max rpm you have

have the same boat with a 4,3 v6 vortec
my max rpm should be between 4300-4800
have meddled with various props only to find out that a 4 blade drops the rpm with about 500 rpm
that's about 35 hp
found out that the original 3 blade was the best one (4800 wot rpm)
take of and getting in plane is best.
i yust have to live with a fact that a 4,3 is a nice and economic engine but not quit up to the job
but
an average adult is about 70-80 kgs
some people are heavier and filled up tank's (water and gas) can play a negative role too

Hey there, i have a 2400scr with the 5.7LX alpha1. I have played with some props as well. What works best for me is a 19pitch high five. It will give me 4600rpm max @ 38-42mph depending on the load, and it gives me a cruise of 30mph (gps) @ 3650rpm. I have no problem getting on plane with two adults & two kids, full fuel, water, camping gear, grocery's, beer..etc..etc..i fact we just had 7 people on board for the weekend and had no issues......but i wonder how much a b3 would make a difference?...i bet a 17 or 18 pitch highfive would be a great choice as well.....
cheers

.....we also pull the kids on the tube with no issues when we are loaded up on the way to the camping sites...
