The Boating Forum - twin suzuki 140 four stroke's (prop pitch)

does anyone out here know??? about prop pitch??? the dealer wonted to put on 15 degree props.and a friend told me that's not enough.... for your boat (25 foot aquasport) so i'm haveing them put on 20degree props???? right or wrong????????
better on top end???? or out of the whole???

I agree that 15 pitch is way off!!! If you look at the test done on suzuki.com with the diff boat you can get a pretty good idea on which prop you will need!!!!!

I have a 24.6 boat with the same setup you are rigging and I went with 14 X 19 props!!!! ask the dealer to let you try diff props to find which work best for you!!!
That is what I would do!!!!

Ask BIG E he will surely know... HE IS THE ALMIGHTY OF SUZUKI KNOWLEDGE......

thank's i'll do just that!!!!! my test run with the tec. is on friday.... ask him to switch props to see wich is better!!! thank's again :) :grin: :grin: :o

Here are some test results for a 25 Aquasport using 14x22 props. The results are inpressive. I'm running the same props on a 23 YF with DF140's.

I have Grady White 252g with twin 140 Suzuki's. the dealer put 20'' ss props on it and that seems to be right. He said I should be looking for a WOT rpm between 5800 and 6200 rpm. WOT with these props is 5950 which is just about right. That figures out to 41 mph (by my gps) and 5 gals per hour each (5 gals per hour at normal running speed which for me is around 3800-4000 rpm or 28-30mph. I have no idea how much fuel I would use at WOT but I bet it would be a lot). As far as the hole shot goes. What does that mean? I throttle up easy. Just my way I guess.
