Hot boat too damn loud? Slip in silencers!

- Is your hot boat too damn loud? Keep the man off your back with these performance high flow slip in silencers for 4” exhaust headers. In short: These Baffles whether running wet or dry, over or under, should bring you into dB noise compliance on the water in the 700HP and under range.
"Whether you believe that or not i don't really care"..... 😂🤣😂🤣 this guy is freaking awesome! 0 f***s given!
Pretty bad ass boat!! That thing sounds great!!
Love your boat, great work.
I don't know if I would live in a state that I'd have to worry about how loud my engine was
Thank for the info bro, I will try it my boat its crazy loud
looks like they went in backwards, slots should face into the exhaust flow , beautiful boat though
Thomas May that’s what I was thinking, but there may have been directional arrows on the baffles that I didn’t see
Sharp looking boat. Sounds great with/without the baffles, but wide open this thing sounds like a fucking monster bruh👌
I have a 1972 miller jet boat with a 454 and I'm in nor cal also
We’re do you launch at
You have plugs in the transom. Run the exhaust thru the transom. It will quiet it down.
OMG!!! You are. Killing that RAT !!!!! Please when you start that thing clean it out. It is loading up so bad. And another thing is I nodded off three times watching this video and I apologize in my opinion I think it got louder. I think you ever forget about the baffle thing it sounds better open header and when you cut the water to it it will gargle the noise out LOL other than my complaints that is a beautiful boat
Im running same big block 600 horse and its loud with drag pipes.I have not been told by any boat patrol.They dont care on the river or havasu but othet places do
Horsepower whisperer, that's hilarious!
Thanks for the demo. Similar set-up boat (Eliminator) out near Sebastopol. Maybe set-up a notice for meet & greets at CP Performance ... We all need to share resources and ideas :D
Sounds much better 👌
ignition wires, check. nice video
Good job it gave me so much information
You need more jet boat content. Great video hope you still have the boat if so any updates on it?
Neither do I own a boat nor am I planning on buying one but I gotta admit, this video was very informative.
Your vehicle is stunning, my man. Excellent choice of colors and that sexy engine brings tears of joy to my German eyes. Beautiful chrome lining on the instruments. The only thing that doesn't quite fit is the steering wheel, but that's just my opinion. A dark wooden one with lacquer finish would be incredible.
I hope you can enjoy this gorgeous beast for many summers to come. Much love from Hamburg!
mike thanks, I couldn’t agree more about the steering wheel, I actually just had to retrofit the entire steering system due to the fact that the company called Morse who made the original components went out of business some time ago. I am expanding my knowledge of the aftermarket and I’ll probably get a new steering wheel now that the steering system itself is working properly. I have a bigger problem right now though, the original fuel tanks are steel and they’re behind fiber glass.
If you want a quiet boat go get a capri or something. Part of the point of a boat like this is to be loud and obnoxious.
Hey there buddy The boat looks good what your baffles are in backwards when you look in the pipes you're not supposed to see those scoops in the thing they're supposed to be headed towards the header so it traps the sound
I came on UA-cam looking for this exact information. I looked at my baffles that I installed 10 years ago and thought “why did I put them in backwards?” Well the hole they have pre drilled gives the impression they install that way. Have you by chance actually installed a pair of these the other way around?
Sounds good man ...id believe your power number thats a pretty ez Power number to get with a bbc ...my pretty much stock olds 455 (468) made 534 hp @5500 with just some compression 11to1 and a cam 530 lift w/236/248 @50. And a single plane everything else was stock lol crank rods heads lol
I just bought a used 2002 SeaDoo Utopia jet boat and it is crazy loud! Do you have any suggestions for noise reduction for that type of boat? Very frustrating.
Look into anti-reversion resonators/mufflers or build your own & a rebuildable resonator & use advanced Acousta-fil. Also, study David Vizard Zero Loss Exhaust & his Exhaust Pressure Wave Termination Box. Very advanced scientific exhaust methodology
What is the name and model of the boat?? Thaks nice project!
1972 Southwind
There in back wards the cups facing in to catch the sound try it turn water on to exhaust
nothing like draggin a 5 minute video out. My god man stop talking already.
You can clean that steering wheel with light steel wool and polish . Damn son WTF ?
Buys jet boat(known for being loud and proud)
Claims cast iron headed 454 with mild cam makes 710hp but doesn't produce Dyno sheet
Installs power robbing silencers that really didn't change the sound.
GG mate, and for future advice, your engine WILL NEED retuned for the massive restriction you shoved into that engines exhaust.
But in all seriousness man I've been around engines my whole life, for 700 out of a 454 you'd need at least 12:1 compression, high flow aluminum heads, pretty beefy roller cam, and high octane fuel or E85.
you are a douche bag.
A Helgeson you can get 700 out of a 454 with just a good set of heads , cam , intake and carb .
Funny how noone complains about weed eaters or lawnmowers at 7 am in rich neighborhoods but a jet boat ohh hell no!! Cali is ridiculous and jet boats are transient noise meaning it's there and gone in 1 minute
If the pump is tight.. what Rpm does your engine spin up to. A jet boat guy many moons ago told me jet drive is nothing more than a Dyno. Don't really care if you believe what know. I miss my old jet boat :(. Cheapest speed and fuel saving rig i ever added to my boat was a MDS(think the model number AL) spark box, added just under 200rpm right out of the box. either there is something under theengine making the rattle noise or the u joints are gone, but kinda makes the sound that the main bearing in the pump is gone. BOAT, Bring On Another Thousand. ;)
Can I ask what cam and heads you are running? Sounds good.
Get away from dry stacks
You could have done that tutorial or that little show in about 30 seconds so before and after you need to practice your setup in your delivery we don't care about your other stuff buddy I'll do want to know is it louder or is it quieter have a nice
What I'm really looking for is actual Dyno results for high dry headers vs low water cooled manifolds? Headers with and without muffler inserts, then say Glenwood or Nicson manifolds ?? There is chatter and speculation that it's anywhere from 5~25 HP loss. But I have never seen actual test data. Since our Jet Boats max RPM can be controlled by impeller size and nozzle, I wanna know what the hit is at 5,000 RPM ??
If it's say 8 HP, so what ... I'd give that up in a heart beat to keep the girls hair and arms away from the headers, and to be able to cruise a shoreline with homes and swim beaches w/o tee'ing everyone off. If it's 25 HP, that's a different story ...
Used these once. Boat blew them out in first run
hey i know this guy
What's up like the float.!! I just bought a 73 Southwind if you're close to my area I'd like to take them out for a spin. If you still have your's let me know
Please post a vid of your boat on the water!! Whats its name?
Are you supposed to turn on the engine first and then the water not the other way around? That's what my manual says for my jetboat.
gmoua1234 it’s really just to make sure the seals in the jet pump are not dry on start up and during repair/testing operation, an issue you obviously won’t have if the boat is in the water. 👍🏻
@@mobileenginemedics9679 what kind of jet boat do you have? It's usually only the case on waverunners and jet boats with small engines like that. In this case there's no risk of water flooding the exhaust and running into the engine.
These boats are not the same kind of animal as a Rotax or Yamaha powered runabout jet.
Still floating around NorCal?
Hey could you maybe send me some pics on how you have your water lines plumed
EliteAirsoft760 sure PM me on Facebook @ Zack Attack, search Sacramento, pic is of me and my puppy
Bro you still have this boat??
Is that a Sunkisst?
Hey man...where'd u get the plugs for the transom...to put the headers on...help please
Call JBP @ 1 (805) 466-4719 they should be able to sell you some or steer you in the right direction. CP performance used to sell them but I can’t find them on their site anymore. If that doesn’t turn up anything call Southwind hot boats in rancho Cordova he knows everything. Helped me find some old morse steering parts before.
@@mobileenginemedics9679 thank you...been putting off putting these headers on my bbf due to not being able to find plugs
I’m in Bakersfield what’s up
OK 1st things 1st There would be no ticket for loud exhaust if you lived in the state of Jefferson 2nd that is not a motor in that boat that is a engine 3rd We all need to see a bikini or thong in this video To help with the tutorial
devin welson it’s time for SOJ51! You’re right definitely an engine. And I was wearing a thong the whole time but the dance scene got edited for time.
State of Jefferson, haha! Godspeed my dudes, CA is just way too big. You need that self-determination, who'd want to be ruled by those SoCal lunatics?
I don't like wet manifolds they suck ND u lose horsepower
Your running a jet pump and your afraid of 5 HP getting away.
My brother you seem to be a very intelligent man. Keep up the great work on the boat! But please, don't say these ones.
"These" is already the plural form of "this" so there is no need for "ones".
I don't not disagree wit you's. "Cuase I knows what good inglish is too!
…..why do you have a “HORN” mounted up on top of the bow??? 🤣
Horns are mandatory boating equipment.
Too much talking and stalling around ............
)
A whole lot of nothing . 🤣
