My 2024 255XD Build/Mods

[FSH 210 Sport]

Now that you have tried the cones do you think you’ll be going with the twin screw impellers to eliminate your cavitation ?

Looks like the sound insulation is done well on your boat!

Yeah, it’s much quieter than the 242X we had.

I feel like once adjusted correctly, the L13 cones should get rid of most of the cavitation. But if it remains an issue, I’m not against swapping impellers.

Just thought I would get a thread started to keep up with the things I am working on.

I've got a list as long as both my arms of the stuff I would like to do so I'll try to update regularly with photos and info.

Round #1 of parts on order currently:
- 48" guide posts
- Slick Stick guide post cover in black
- Oil Catch Cans (Amazon Special - didn't seem necessary to throw more than $25-30 at something as simple as an oil catch can)
- Lucky 13 Pump Cones
- Riva Racing Intake Manifold Upgrade (Ribbon Deletes)
- RIva Racing Blow Off Valve Kits
- Riva Racing Vacuum Port Adapter (to avoid drilling the manifold)
- Jet Boat Pilot 3D Registration #s to match my interior
- Stoltz Bow Roller
- Flame Arrester conical style air filters to get rid of the ariboxes

Round #2 coming soon - the wife insists that I fix the stereo quickly.

Will any of these mods give the boat a better exhaust note? Exhaust, the stereo and the carpet are the only things I would change in my AR 250. Stereo is underway, carpet is up next but I have not heard of anything to make the boat sound better

Nothing I’m doing will change the exhaust note.

Thay are 4cyl and have a certain note that won't change and on plane the exhaust is well above water level .........open type exhaust.

After it passes through the water lock(s) correct?

I love these sorts of threads. Good stuff. For the uninitiated amongst us, what improvement does the conical suppresser/filter make?

More air flow.

More air flow.

Well, yeah...but I guess I was just surprised that one would notice a performance difference. Reading the thread more carefully, I see that you note that you dis see an acceleration improvement.

Got my stereo upgrade finished today. Was rushing and was too hot, so I forgot to take photos. But it sounds great. I’ll get some photos later this week when we’re out on it being lazy. Thanks again to @jacoviii for helping me out with custom harnesses to convert factory inputs/outputs to RCAs and speaker wire.
