Any benefits to a 4 blade on 250 G2

Any benefits to 4 blade prop for my G2?  250 G2 is pushing a Ranger 212LS Reata Fish & Play.  Boat weighs 2215 pounds w/o motor or gear.  G2 is also mounted to a 4" atlas hydraulic jackplate.

On many hulls with the Evinrude E-TEC G2, the new 4-bade Rx4 propeller often outperforms popular 3 bladed props. Work with your dealer to try several sizes to find the best one.

BluewaterBill, are you seeing better performance on top end with that 4 blade Rx4?  How about heat of summer vs colder months? What pitch would you recommend I ask to start with? Thanks!

What propeller model and size do you have on your motor now and what is the top speed and top rpm that you can achieve with it?

Stamped on the hub of the prop behind the prop nut and washer.

Re: Any benefits to a 4 blade on 250 G2

Bill, finally got the information for you.

"barely" tapped 5600 RPM

59.1 mph

2 people fully loaded with full tank of fuel (39 gal.), full oil tank and ice chest.

i have a 4" hydraulic atlas jackplate

prop is a 3 blade rebel 14-7/8 x 22 (part# 763996)

boat weight dry 2215# according to rangers website (212LS) 21' 4"

i would like to achieve more top-end, faster bow-lift and better performance in turns as prop wants to cavitate.

this boat has a difficult time getting its nose up

 

let me know where you think I should start on props

thanks in advance!

Ryan

[ Edited ]

Probably a 4-blade RX4 in a 22" should be the starting point but a 24" may work depending on your boat. It is trial and error to find the best all-around propeller.

 

The ideal rpm to shoot for is 5600-5800 but anywhere in the 5400-6000 rpm operating range is acceptable.

BluewaterBill, I'm still working with my dealer on getting a prop to try.  I haven't forgot you on the performance.  I'll be in touch.
