Prop concepts

oh I have - responses are unfortunatley - go to deisel or change gears to 2.5:1 and find 6 blade rollas all of which are too much money for a working slob with two in college. Looking for a cost effective solution

I dont mean to insult your intelligence but both engines are on 8 cylinders? Air filters clean and WOT is available (at the carbs). has some one made the exhausts? Can you blip the engines up over 4100 in neutral.

Have you any pics

[Swamplizard]

yes they blip to 5k
everything looks clean and good
no insults taken - I have checked and rechecked fuel delivery etc.

Next step is to get the motors pulled and dynoed. Also changing out the Borg Warner 71s for a pair of healthy 72Cs which can take more power/torque and I will change the ratio from 1.5:1 to 2.10:1.

This way I will know th power of the motors - no guessing - and know the gears are not slipping. Wish me luck - had to wait for dollars to be available so took a year off from boating.
