I've been running a 19" Viper prop and have finally had enough! Poor hole shot and not such a good top end. The etec revs out to 5600 no probs, and gets there impressively quickly! So poor bite from the prop and I suspect that I am getting excessive slip. I've tried a 21" Rebel but it was too much and I only managed to get 5000 rpm. The local dealer is unwilling to get a prop in for me to try, despite recommending a 19" Rev4 4 blader. I have to buy without trying, which I am reluctant to do.
So, does anyone know of a dealer who might be willing to loan a 19" Rev4 for me to try? Obviously if it is OK, I'll buy it, likewise if a ding it
One of the factors that I want to try out is engine height, at the moment I am running one hole off of the bottom as the Viper is known to run higher than some props, hopefully dropping it one hole will be sufficient. I know it is a long shot, but has anyone any direct experience of a Rev4 on an etec on a 6.5 Vipermax?
