Hello yet again jaxmyth, What is the intended use of your 17 Montauk? What cargo loads (people, gear, etc.) do you expect to have from time to time.

Obviously there is a noticable difference between your Whaler and mine even thought we have like outboards.
I have run two props on my Dauntless 15 and have noticed differences between them. I typically boat with my family (4 of us plus snorkling gear, and cooler with treats). Our two kids are late teens so adult weights are in play.

My first prop was a Solas 13-1/4" x 17P (Round ear 3 blade) in Strainless Steel. The Round-Ear props are refered to as "Bow-lifting" style. Getting on plane promptly is not this props best trait, once on plane good mid-range to top-end. I try not to push beyond 5200 RPM's if not needed, MPH on GPS around 38 to 40 (with near perfect smooth chop) and with loads mentioned above. This prop gets off plane very quickly if slowing down while negotiating chop and swells!!!

My second prop (purchased used but in excellent condition) is a Power Tech 13" x 17P (Semi/Cleaver 3 blade) in Stainless Steel. This prop is refered to as a "Stern-lifting" style due to the semi-cleaver (shark fin) blades and is very similar to the Yamaha prop you mentioned in Black trim. I get "out of the hole" or on plane in half the time and with less engine effort than I did with the Solas having same loads. Mid-range to top-end pull is consistant, again I try to stay below 5200 RPM's but there's still throttle left for a 5500 push if I needed it. MPH on GPS is between 36 to 38 (with near perfect smooth chop) without pushing the Yamaha 90 hard.

I now keep the Solas as a back-up/spare for a "just-in -case" day. From your posted selections I viewed a few props with 15P, these are suggested?

Hope this helps...
Best,
Angel M.
