That High Five is a brute power prop – water ski, tubing, and super rough water.
On your size boat, a 3 prop (sized correctly should be very adequate for your needs. Heavier boats in big water will often go to a 4 blade for added control and sacrifice a couple MPH.
Is your current rpms 5250, or is that the motor’s specifications for max rpms? Do you have a tach in the boat? Ultimately you will need to know what your max RPMs are at wide open throttle with your current prop, weight of boat/engine, gear, gas,…and speed. A good prop guy should be able to dial you into 1 or 2 props based on that information.
Since your investing in stainless, you want to get the most out of your prop. Stay away from generic props with “Micky-Mouse” ears for blades. The cupping, rake, venting will make huge differences between individual props. The lazer II has Aft Rake for lifting your bow and not requiring you trim your motor all the way up on the fly. It also has a decent amount of cupping which is the ability of the prop the actually throw water. (only the last about 1/4″ of your prop actually propels you forward)
Below is a generic Merc prop with Micky mouse ears. No adjustment to the rake, so you “push” is restricted to only 90 degrees from the your transom. The prop also lacks cupping. Combined, this prop will give you a lot of slip in the water.
