Hello i want to get my dad a 4 blade prop for his evinrude E-tec 225. I was wondering what pitch i should get also? And also would a 4 blade be good for this motor? I want to get him this for a xmas present. Any online stores you guys could recommend would be great. thanks everyone!

pciking a prop isnt that simple. it usually involves trial and error to get the right pitch.

It is more complicated than just the motor - boat length, weight, etc all come into play. The point is to get the prop that allows the motor to turn at the correct WOT RPM range. Too little pitch, and it revs too high. Too much pitch, and it bogs down. both are bad for the motor.

That said, it is a really nice idea and I'm sure he'll love it. If it were me, I'd go to the dealer that sold him the motor, and get his input, or get a gift certificate for the new prop and install. They'll make sure that it's the right prop.

good luck.

Power tech make excellent props.
They can figure out what you need and ship it out.

If it is wrong they will take it back and send you the right one. It is probably correct on the first try 75% of the time.

I have a pair on my Palmetto. 4 blade.

There is probably a dealer near you. check their page and see.

They will run you $300+ though.

Wayne:

As others said, we (you) need MUCH more info before you can simply pick a prop for that motor. We would need to know the hull make, length, beam, deadrise, and weight, as well as current performance numbers from the existing prop, plus it's make, diameter, and pitch. We also would need to know what RPMs his OB was turning @ WOT with a 2/3rds load of fuel, plus gear and 2 people on board.

4-Blade Props:
From the experience a few of us had this past season with 225hp Evinrude (2-stroke) motors, heavy offshore hulls, and premium 3 and 4-blade props, I can tell you with some degree of confidence that the 4-blade prop will shine provided your boat has at least 20 degrees of deadrise.

I tried one on my heavy Parker (modV hull) and it added so much bowlift that I had to really use my trim tabs, which killed my miles-per-gallon efficiency. Now my friend tried that same prop on his 22' deep-V (21 degree) CC hull, 200hp OB, and the performance was, in his words, "outstanding". The boat got on place 2-3x times as fast, stayed hooked up in rough offshore waters and while in turns, and the best part, he only lost 50 RPMs from the previous prop he was using, which was a high-raked performance offshore prop.

E-Tec Props:
FWIW, due to the beefed up gearcase on the E-Tec lower unit, Bomb found that they needed to tweak their props to give best performance, see below. Stock OMC/Bomb props were OK to very good in the past, but were so-so on the newer gearcase.

New Rebel Propellers for E-Tec Motors
BRP now offers eight propeller lines to meet every boat application with the addition of the Rebel propellers. The new Rebel propellers are designed and engineered to deliver even greater fuel economy plus improved midrange and top-end performance on the 60 and 90-degree V6 Evinrude E-TEC engines. Rebel props are great in offshore, large runabouts and even large pontoon boat applications for maximum boat and engine performance.

These new 3-blade propellers are designed with a large diameter and efficient blade contour to provide faster speeds at lower rpm, improved fuel economy for more miles per gallon, increased top end speed, and a longer cruise range. The Rebel propellers are made of highly polished stainless steel with right-hand and left-hand rotation available. Six pitches are offered; 15 in. (380 mm), 17 in. (432 mm), 19 in. (483 mm), 21 in. (533 mm), 23 in. (584 mm), and 25 in. (635 mm).

Summary:
With all that said ... sometimes picking a prop is tough, as no 2 props from different makes allegedly of the same size (pitch or diameter) are the same. Some use larger blade surfaces, faster cupping, different edge profiles ... and so on.

The best advise I could give you would be to give him a gift certificate to a Bomb dealer, if you think he'd want one of the new Rebel props. Make darn sure though, that the dealer will work with you to swap the prop out if the performance is off or the RPMs too low or too high. As Capt SuperFly said, you MUST make sure that OB turns the right number of RPMs @ WOT with a good load on, otherwise you WILL seriously damage that motor.
