Nice shape. You did very well at 28 G's with a trailer. I got that for my 2000 model with no trailer. Carpet's and canvas only had a year or so left in them too. Congrats!
I did a full throttle run end of season just to see where I was for performance. I was thinking about going 4 blade next season. Anyway...I was able to hit 40mph @ around 4500. One person/20g fuel/lightly loaded. She can easily hit 35 with wife and I with normal gear during the summer running around 4200. 22P stock props - verified by GPS on chart plotter and Vessel View/phone.
at 4200 going 35mph this tells me I am severely under propped.
Have you had the pitch checked/trued on the props? I would think the 383 would be plenty to push it to 40mph. My experience with tuning impellors on jetskis, would have me guessing the pitch is off. 4 blade for launch/torque, but the final pitch is gonna govern your speed. What is the WOT on the 383?
Ran the boat in beautiful weather today. Got Vessel View Mobile hooked up. Max RPM's about 4800, speed about 37-8 mph. Didn't spend much time up there because I won't be running up there. 4000 rpms=30 mph and 16 gph. What was nice to find was that between about 3200 and 4000 rpm mpg was always around 2mpg (some minor variations but no standouts up or down). So depending on sea conditions I can cruise at a speed in that range that is comfortable and not worry that I am killing myself on gas. If your engine supports Vessel View Mobile (generally Merc's from ~2003 and newer) it is a great add-on IMHO
I did a bunch of VVM captures and put into a spreadsheet that can give you theoretical output as to range based on distance, speed and GPH. Good for a guide to optimum running, eg I could ease up and spend 10 hours getting to NYC vs 6 for another 3 gallons.

Those are some GREAT speed numbers. What motor and props again??
I would say that is the performance of mine without all the fancy stuff to figure it out...22.5Pitch props are what I think I have...same motor and bravo III

Congrats!
2018 Cherokee 39RL Land Yacht (Sorry...)
A little cruise in Charlotte Harbor with the wife and the new to me Rinker 270.
Unrelated but the Twisted Tea half and half are crazy good.
