I have a 322 with 7.4L bravo 1 drives. It has 13.7 x 19 props. I am going to have them checked by prop scan. I bought the boat used and it is a 1995 so i don't know what kind of shape they are in. I have one moter burning 2 gallon per hour more at 3400 rpm and 10 gallon per hour more at wot. Any advice?
 
Get your compression checked. How old are plug wires? When was last time you had it tuned up?
 
Change plus 2 years ago and i do not know on the wires. I think I will change the wires this year.
 
Assuming your engines are tuned and bottom clean you really need to know what your WOT rpm's are. With that info a good prop shop can tune the props to your setup.
 
Prop scan is far more accurate than any shop doing tuning by hand but they really need to know your RPMs at WOT to tune them right. Prop Scan determines that one of my wheels was pitched a bit more agressively that the other and each blade was a bit more aggressive that the previous which is a trait of hand tuning.
