Wow, I live in outside Greensboro, NC BUT boat is on Perdido Key, Fl.
Come on down!

Getting all the little things fixed. Dash light switch was bad and the brand new Sierra water temp sending unit was bad out of the box! Going to get a stereo upgrade in the next couple of weeks at which point I will probably also be modifying the ST box for some more noise. The mags sound like V6's currently.

That means you can sneak up on people lol . It doesn’t get a little louder once water drains out on plane or do you mean when docking? I can’t hear my boat with stereo cranked and wind in hair either but I’m sure others can . I’d love to go for a ride in one of these bigger formulas but then I’d be to motivated to buy one

Let’s see some fly by vids please

Don't have any flybys but here is the boat running about 60 from the pax seat...

Ya video taken from the helm usually just the wind sound effects. I have no idea what mine sounds like except from my father in law “ your boat is loud” when he heard it from shore

You should be at least 48 - 5000 rpm with the Mags. You might want to Lab your 25s and turn them into 24s, this should still help you not lose as much of your cruise speed as you will going to 23s but help you pull higher rpm on the top end. If you haven't given it a complete tune up I would do that before I did anything with the props. Make sure when you are testing props that you are always at the same trim level trim level, prop shafts parallel with the bottom of the boat. Run a straight edge off the bottom and line up the shaft, then note where it is on your drive indicator.
As far as the sound goes, I have always taken off the rubber flaps and cut the baffles out of the swim platform. You can go in from the back where the flaps where with the biggest hole saw that will fit or long saw blade. The baffle is very thin and cuts out very easy. Gives you a much nicer sound without being real loud.
F14A Water Jet's 311, the one that said it is a twin to yours' is one of my old boats. I cut the baffles out of that one when I bought it new, Sounded must better.

Now plug in earbuds to hear this:

Thanks for the info. I have the boat on the trailer right now and actually cut the baffles out yesterday. I also added four 2” drain holes on the bottom side of the platform (one under each exhaust path).

I just did new fuel filters, plugs, wires, caps, rotors and thermostats on both engines along with adjusting both throttle cables for WOT (both needed adjustment, port moreso at it seemed to be missing the last 10% or so).

Plan is to drop it back in the water tomorrow for another shakedown and see where I’m at.

I think I have 6 five inch holes. 2 hold each on the outboard supports and one whole each on the inboard exhaust supports.
