Highfive question?

[lrdchaos]

Ok, my boat came with a mercury vengence 19 pitch 3 blade, it ran just a touch over 5k rpms. I replaced it with a 17 pitch 4blade solas and it runs approx 48-4900 rpms. I have a chance to get a mercury highfive at a decent price, the only thing is I can't get the highfive in the 19 pitch, only a 17 or a 21. If I was running just a touch over 5k with a 3 blade where would I be at with a five blade? I really don't care about losing topend....I want stump pulling power out of the hole. Which would you get? The 21 or the 17? I believe the 17 will pull to many rpms, but I don't know how much the 21 pitch would drop the rpms.

Re: Highfive question?

21 in an H5 would be like a 23-24 in a 3-bld and it would not be a stump puller...the 17 would be the better pulling prop in the H5, but it will pull just slightly less RPM than your 4-bld in 17.
