Yeah I guess the gearcase has a slightly larger diameter than the standard ones so you're limited... but also a good problem to have with 350 horses pushing you along! With some tweaks you should be able to see a little more mph, but keep in mind when other boats are passing you by they don't have the awesomeness of an RX.

Just picked up my new 2025 QSBA with the 400 v10, Just so everyone knows the 350 & 400 v10 only comes with a 4 blade prop that was designed for these v10s. The v10s RPM range is 5800-6400. I have only 3hours so just getting some hours before hammering. Specs 20 pitch revolution, 6080 RPM ( still pulling) 51 MPH, 2 people & 120 lbs worth of dogs, motor in the lowest position. May raise it after more seat time. 22 degrees trim, 23 is max according to Mercury. That's also with the cladded arch, which adds close to 1K pounds to the boat. Your RPMs are too low. try raising the trim, u can't over trim this motor as Mercury has an internal stop at 23 degrees. Good luck & lets us know.

I totally agree. Such a nice boat. Quality all the way around.

Wow that’s such useful information. I only trimmed it to 7 degrees. A lot more trim on the table. User error lol

Did Ken mention anything about the vents ?

Jack I was at my boat today and noticed one of the plugs in my Enertia was missing from the vent. What's the impact of 1 missing out of the 3 plugs?
 
Many years ago ,my dealer told me dont touch them . Since you are missing one , I guess I should check mine .

I have a 2024 Bennington Rx25sba tritoon with a Mercury V10 350 verrado . Had it on the lake this weekend and opened it up and to my disappointment I got beat by a Avalon 25’ Mercury 250. My boat topped out at 43 mph at 5250 rpm’s. Had 4 adults and one child on board. A little head wind with calm waters. All the forums and posts I read say the setup I have should max out at around 54mph and at 6400rpms. My question is what the heck LOL?

I have a 2021 RX25SB with a Yamaha SHO 250 V6. I can easily do 45 mph at 5000 rpm with 4 or 5 people and a full fuel tank. I wanted a 300 HP but the salesman talked me into the SHO and I am glad I listened. When normal cruising most of the time the motor is silky smoot, quiet and sips the fuel slowley. With 56 gl tank I go forever it seem like.

Hello BigKahuna. Thank you for the response. I realize the boat is a bigger boat and on the heavier side. Yes both Bimini tops were open and only 1 keg of beer on board lol ( JK of course) but yes a few soft sided coolers were on board. I will look into the pro make/model/ and size. As far water in the pontoons I’m not sure. If there is how do you drain them? As far as the performance of the boat with just the wife and I I haven’t opened it up because I was in the break in period still. Just hit the 20 hour mark. One other question and this is probably something I will figure out but I had it trimmed to 6 to 7 while at full throttle. At cruising speed it seems to ride perfect at 3 or 4. What is the max trim I can go at full throttle. Obviously you don’t want to much trim because it won’t allow water to cool the motor at to much trim.

I would start with the prop. Ask the dealer what pitch is the prop then you can have an expensive back up prop. Its the easiest way to get top-end speed. If your going to ski behind it you'll need a prop-pitched for something quicker out of the hole. Make sure you have the motor trimmed properly
