starting from scratch, v-bottom bowrider prop selection, pitch and diamiter?
1995 starcraft v-bottom bowrider
120hp force outboard
17'2" lenght
beam 82"
max depth 30"
dry weight 1363 ( i think the boat is on the heavier side, i believe it to be some wet )
fuel cap. 24 gal.
gear ratio 2.70:1
full rpm 5250
#1 i bought used with a 20" quicksilver, it did approx 42mph at 4700 rpmsand sluggish out hole.
i tried getting repitched to a 18" with a cup.
that was terable, felt like bushing spun, rebushined and same thing happened, as soon as it starts on step, slipping, rpm tacks out. if i play with trim, i can get on top with very very light load, top speed aprox 33mph at 5000rpm
very confusing
# 2 while quicksilver in shop i borrower a power tech 17" pitch, much better, but only 37mph top end at 5150rpms and jumps out the hole.
i repitched to get my rpm up to maxium 5250 inorder to get a faster cruise speed.
im lost on what happened to my quicksilver.
So what would be a good idea for a new prop, make, pitch and diamiter? i need a spare anyway.
any help or guidence would be greatly appreciated.
