Prop for Searrider 4m

[russiarulez]

Just got me a SR4 (Deluxe version) recently, haven't had it in the water yet due to fixing small stuff/weather.
I put a Yamaha 40 two stroke on it.
I plan on having two people with 12gallons of gas and some fishing gear most of the time.
I'll be getting a tach here shortly and start messing with getting the pitch right.

I just want to see what pitch are people running on their SR4's with 40-50hp?

Without a console you should try a 15" pitch for best all round and 16" pitch for max. top end, but with less acceleration power.

With a console you should stick to 15" pitch.

Considering you don't know which model Yamaha 40 is on there you seem to be awfully quick to give advice.


Mine ran a 10 3/8x14" on a Mariner 50 and made 44mph (GPS was in MPH only) No wind, slack water. Centre console, 50 litres of fuel aboard. No rev reading as didn't have a tach fitted but it wasn't as quick onto the plane as I'd have liked with 3 people onboard.

It's a 95 two stroke Yamaha 3 cylinder if that helps. 40TLRT model if I remember correctly.

Whats on there at the moment and do you know the gear ratio?

[reinier]

Yamaha 40hp 2-stroke 3 cilinder gear is 26/13 or in otherwords 2:1.

Sorry, I already assumed that it was a 3 cilinder...

Right now it has 11 pitch prop which is too small of a pitch for this setup.
