    Hi guys… hoping i can get some answers here.

    I own an 07 2320 with a yamaha 225 4 stroke engine. I had a friend ride the boat with me and mentioned that I may need to re prop to get better performance.

    Im pretty sure it has a prop from the factory. I didnt pull it off to see the numbers on but the only markings i could find were "17-T" for whatever that is worth.

    Here are some of my numbers;

    Redline/Max RPM: 5500/5600 with speed of 34-36 mph fuel burn around 1.4-1.5 mpg

    Average running: 5000 rpm, 27mph, 1.6 mpg…

    Seems like no matter the load or how hard i run her (weather dependent) I always average 1.6 mpg.

    I was told that the motor is suppose to red line at 6000 rpm.

    Can anyone help shed some light on this?

    Your input is gladly appreciated!

    How was the boat loaded when you achieved 5600 rpm? Very light and no fuel or super heavy with 500lbs ice, 8 fat dudes, 10 coolers, full fuel, three topless 'deckhands' and 50 rods....?

    Running wide open throttle achieving that speed is usually 3 guys myself included (I'm 140pounds… most others average 180-200ish), 80 pounds of ice, empty bait tank, 20 rods, usually 70 gallons in gas tank….

    When fully loaded, full 150 gallon tank at wide open throttle, i go maybe 32/33 mph. again, should conditions allow that.

    Ive topped out at 39 mph, but average 35-36mph.

    Tell the truth Billy. You left out 3 bluefin over 100 lbs and 2 over 150 lbs and 5 20 lb yellowtail...that adds up and will affect the performance too.

    Billy that's seems kind of low on the mpg. I have a '02 2310 with bracket and the same motor. My last two trips averaged out to 2.2mpg and I burned 110gallons. I carry 100lbs of ice and 4 guys that average 200lbs each and 48g bait tank. Sea conditions were pretty nice on both trips. I don't care about top end mph, just mpg and low speed planing. I have a 4blade prop and permatrim, which allows me to plane at 16-17mph. My cruise is at 4300-4500 rpm (25mph) and my flow meter says I get around 2.4mpg. Let me know if you have any questions.

    I would buy a Mercury Mirage Plus 17" pitch. You'll pick up about 400 rpm and get way better MPG. I have a Formula 233 with a bracket and a Yamaha 250 and I average about 2.4 MPG with a Mirage plus 19" pitch. My top speed with a heavy load is 46 MPH and 49 lightly loaded. RPM is 6000 loaded and 6100 light.

    not a pro at this stuff but i would say you should be running 4200-4600 rpm at 25 mph and obviously your gonna get better mileage from running lower rpm's. so yes you need a different prop.

    I actually never accounted for that…. lol

    Interesting enough, come to think of it…i only run wide open throttle back home when i have fish on board. yes, i have skunked, but i just slowly roll in. Ill make note of that.

    That is very interesting. Thanks for taking the time to share…… I get NO WHERE near 2mpg.

    My last trip, i did 176 miles. 96 gallons burned. skunk. 3 guys, 100lbs of ice. 65 gallon bait tank filled.

    comes out to 1.8mpg but to be honest….i normally average 1.6 mpg.

    Seems like that 4 blade is the way to go.

    Whats your red line?

    And you have a tower on top and also the motor is on the bracket. The tower will slow the MPH down by t I am not sure what the Armstrong bracket will do in this respect. I have the 200 hp and get 5600 rpm and 32-34 mph on the top end, cruise at 4500-4800 at 25 MPH. Average mpg is a little better at 1.9+ mpg....not 2+. These are always fully loaded. Let me know what you figure out as I am looking to change my prop and possibly add permatrim too.

    Look at this web site! Lots of info about props and performance. The moderator is a guy named Ken who has vast knowledge of props. Google propgods for his web site and lots of old posts on props!

    I found a couple of posts of 2320 Parkers that went with Merc Rev 4 props that really helped performance!

    what he said: get a Mercury Mirage 4-Blade Stainless Steel
    we got a huge bump in performance with it
    you will need the Mercury prop adapter for the Yamaha engine splines, no biggie

    Mercury enertia 3 blade prop is what your going to want. From the info posted the 15x15 enertia will put you near or above 6k rpms with a moderate load. This is the same prop I run on my 2320. Fyi I have the yamaha command link gauges and have never seen my mpg below 2mpg fully loaded. Call ken @ prop gods he's a huge help when picking a prop.

    My 2320 tops out at 37mph @ 6k rpm cruise is 28mph @ 4600 rpm burning 2.3 mpg loaded in smooth seas. Hope this helps good luck
