My Dad has a Ranger 1682VS w/ 90 HP Mercury. I added a four blade prop and performance is better now accept for three issues
1) blow out when turning sharp
2) heavily weighted holeshot is a bit slow
3) other than at WOT and trimmed out the boat plows really badly (have tried multiple props to improve mid range lift with no luck)
I am considering installing a CB Marine Hydrofoil but not sure if it will help or not.
thoughts? am I chasing ghosts?
