Viper Ive been told by a few that 1.5 is the way to go but I dont understand
why. Bob S told me they ran both ratios years ago racing depending on how rough it was.
I have a set of 17/28s that turn 5600 to 5700 and a set of 17.5 31s that turn 5000 maybe 5100.I really dont care for the larger dia due to the fact that it makes the transom climb a little.I tested a set of labbed 17/30s that were perfect. Rob

Thanks G.
How does prop dia effect things going smaller with more blades like 5 or 6.I would really love to talk with someone who has tried this stuff and knows whats what.
Id like to try some different things but these types of props cost as much as a clean used car.

im actually running 1.58... my props are 17.5x28. have not tried anything else but i would say that the 17X30's would be spot on with my current set up.
i am going to add some hp to my engines this winter and i was looking at a #6 conversion but i can not decide rather it would be worth the price or not..
a freind of mine is trying to get me to bolt 5's on but i hear that 5's x dem wont work? i hear so many conflicting stories about 5's working and not working i just dont know what to think. either way i have to do something about stronger drives before next year. i would like mine to break 90 on the gps next year

As we talked about, the 5 is the same length as the 4. Take a straightedge and put it on the bottom of your boat parallel to the centerline of your prop shafts. Then imagine the props 5" upward. Then picture the water flowing under the boat and where the prop would engage it.
If you put 5's on a #3 gimbal withoyt moving the X, the only part that would touch the water woould be the prop tips.
If you convert your drives to 3a's and are meticulous on maintenance, they'll probably get you through a season behind 950's, which is about what you'll need to scratch 90. Holeshots would be a bad idea. Wet 6's are going to cost you somewhere in the neighborhood of 80 to 100 horsepower loss-equivalent. in performance. Dry's cost about 10 grand for the conversion. But like Pat Weissmann says, where else can you pick up 100 hp in your engines for $10K?
Thanks G.
