i answered my own question it's between 4500-5500 now my new question is it has a 14x19 would a 21 pitch prop get me down 400 rpm's?

In theory for each 1" of pitch change it should move your RPM +-200, depending on the direction you take. With that being said, each prop is a little different so your best bet is to work with a dealer that has some test props to find what you like.

I'd try the 21... you may need a 23 with the high gear case lower unit that suzuki (who made the motor for johnson), but your holeshot may suffer a bit with the 23.

Fish2Live - I have this motor and I believe I currently have a 13 1/4 x 19 Hustler aluminum.

I am not at WOT when I hit 5,500 rpms so you may want to look at a 21.

I've thought about swapping props, but I like the holeshot I have and I'm rarely on big water so a few mph top end isn't of great concern.

Enjoy the motor. Mine has been flawless.

    • If anyone here is in the market for an electric smoker, give me an IM. I will soon be listing my MES 40 that has only been used 1 time. It is barely even seasoned!
    • Not yet, but I have been thinking of trying one....
    • I figure any fish that doesn't get into my boat was a wall-hanger for sure. 😀
    • I've never bought a car/truck over $15K, so yeah.  It would take a powerball jackpot before I was in the market for a dealer showroom boat.
    • Dry brine with Mortons Tenderquick, amount directions per pound are on the package in a ziplock in the fridge. Add seasonings like onion, garlic, black pepper, maple sugar or brown, allspice, cinnamon, nutmeg. What ever you prefer. Take meat out of brine and let sit in Fridge overnight. Smoke around the 130 degree mark for 12 hours (for my liking) or as smokey as you like. Cut into 1/8" slices and cook in the oven 425 degrees for 20 to 30 min to your desired crispness. 
    • I just bought two panels that I am going to trim slightly to replace one of the 3 grates on my Big Horn grill... I actually have a buddy that received them this weekend for fathers day and say they work just as advertised on his pellet grill.... I will give an update next week when they arrive.
    • never heard of it....  
    • Since we are talking about searing stations, etc....   Has anyone ever used the Grill Grate product on their pellet grills?   https://www.grillgrate.com/shop-grillgrates/standard-grillgrates/pellet-grills/
    • You've got the right idea. There are a ton of bacon recipes here on HSO if you search for bacon - I've pasted one here to what seemed like one of the more popular brines. I made bacon once, and it turned out OK, but it's a long process.  Good luck and let us know how it turn out.
