i have a 22 placecraft deck boat. it has a 4 blade ss 24 pitch prop. i was wondering if anyone on here was running something different and having improved performance.

Need to know what your specs are now - top speed -max rpm so you can see what your slip percentage is. You want to be in the 12-13% range for that type of hull.

When looking at prop options, you will probably want something that bow lifts your deck boat as opposed to stern lifting it.

lavey sounds like you know what your talking about.

i have a 22 superdeck with the 496 mag in it.

it just seems to run out of speed before it runs out of power. seems like with different prop she would gain some speed.

i dont know what specs you are talking about and this is my first IO so i am not too sure what i am doing just yet. and at around 500$ for a prop i dont want to just start buying some and see what works.

any help would be great.

Granted, props are expensive, but if you buy a prop from a good specialist propshop, they will usually do exchanges and make changes to dial it in. Just don't hit a rock and lop an ear off of it! Call a couple of places and get a consensus of opinion before you choose a shop to work with.

If you plan on doing a lot of boating, you are going to want a spare prop anyway......

Well, a lot of variables come into play here. Such as the hot temp which drains HP from your motor, the amount of people you are carrying, your familiarity with your new boat and knowing your trim range for particular RPM you are at. If you are over trimming it, your speed will drop while RPM increases.

See what your current prop slip percentage is. Google "prop slip calculator" and fill in the numbers to check your slip and then work from there. In that size boat with the 375hp motor, I am guessing you are in the 60-65mph range when loaded for boating?

I have the same boat 496mag, 4 blade 26p ss and seems to do good best I have seen is 65-67 loaded with gear and family but I see 60-65 more than anything. When I got the boat guy a dealer said he got 74 out of it sounds like a fishing story to me.
