Propeller shoot out!!! Does changing the prop make a difference???? Interesting results!!

After being on the fence about buying a brand new 40hp to put on my beloved tinny I thought id go spend the day trying out new props to see what the difference would be with very interesting results!! Comment down below do you guys think I should just bite the bullet and get a 40hp for the old girl? 1000 views ill do it ;)

IMO. 4 blades shouldn't be faster, but give better results outta the hole. Less cavitation too while turning. Possibiy better fuel economy. Old warn out props don't help. I reckon a new 3 would be bette for you

That's what I thought maybe with a higher hp motor you could tell the difference more. I will be putting a brand new 40hp on the boat in 6 months so not overly worried haha

Change 3 blade prop pitch. Bigger prop = bigger topend. Smaller prop gives you the hole shot. I run a 11 for the shot and a 12 to squeeze a little more out the top.

I also have a 25 hp that has trouble planing with passengers. Also debating a 40 but don’t want to spend the money. Also going to try prop changes first. I wish this test was a test that changed the pitches of the props instead of the blade number. I think that would’ve been a better test for you . I’ll lyk how my test goes. 13 foot whaler with 11.25 pitch on 3 blade prop. I know I also have range to go because I’m WOT at 5 k rpm’s and 22 mph and I should be 5600 at WOP at least. Remember the 4 blade prop will take more power to spin and therefor not allow the motor to rev out and reach its rated HP I’m a timely manner. I thought I needed a 4 blade prop for more torque but after doing a ton of research I think my best bet is to keep 3 blade and lower the pitch and get my rpm’s up sooner in the power band and like I said I have 1000 rpm’s to play with up top.( although I’ll probably only push it to 5700 WOP )

Thanks mate!! I could of definitely done a few props to compare! But unfortunately this was the only option they had at the shop. But was still an interesting test! I was surprised the difference it makes!! Goodluck finding the perfect prop mate!!

You’ll probably know it, the “ pitch “ has a bit too do with speed.

Most definitely! It's crazy the difference it makes having the right prop!!
