I am trouble shooting trying to get my Z520 and Evinrude ETEC 250HO to run like it used to. I have the new M2 gear case and lost 3-4 mph. I can only run 68-69 fully loaded with a Fury 25 or 26 right now and the prop specialist at Lake Fork suggested a Power Tech 4 blade RKR4. He said most people with my same setup have seen great results. I am just skeptical about buying an aftermarket prop because they are not cheap! Anybody have anything good/bad to say about Power Tech props??
Steve and the guys at PowerTech build good wheels and they have been around for years............................RR

I tried a 25p Power Tech 4-blade on my 521 a couple years ago. It had been worked by Mark C, so it ran good. I also recently ran a Razor-4. It's the fastest 4-blade I have run so far. I just got my Razor-3. I know it will be a little faster.
I wouldn't worry about running an after market prop. From my experience, they run just as good as factory props. If you want to buy a stock prop, I recommend the Razor. It runs like a blueprinted prop, and it's cheaper.
You should also ask about this on the Evinrude motors boars. This isn't the first time I've heard someone complain about losing speed after changing gear cases.
I bought a 4 blade from them a few years back. I called them on the phoneto give them all the details about my boat, engine etc. Those guys were great!! They told me what I needed and my boat preformed very well with the power tech. If you have questions, call them.
