Stainless Marine Dry vs Dry to the tip
 

I don’t want to be “ that boat “ with the stupid loud exhaust and not a boat to back it up so to speak. I still have time to make a change on my new stuff and my risers be “ dry” and dump the water overboard somewhere. Just how much louder will it be if I do go that route? I’m really nervous to spend this much money and end up having the same stupid problem. Real pros and cons are wanted and any and all advice please!

thanks!

sincerely the reversion water in oil guy LOL

Curious to read answers
but i would think it would be stupid loud for nowadays!!!

Right
 

I think so to and between me and about 4-6 others are about the only real powerboat people on my lake. I’m surrounded by floating minivans and wake boats lol!

My Merc 420 TRS dry to the tip tails were 93db when the sheriff gave me my ticket. It was cool for a couple of summers and then became annoying real quick. I run mufflers now and can listen to the radio while idling 30 mins out to the lake.

And this is dry to the tip on my TRS tails. 1" water pipes at the end.

I see
 

this photo confirms my suspicions even more that my holes are TRS in the transom

Have you PM'd Sick Stinger to see if he has any tails?

Yes
 

yes he has a set that are TRS it looks like but have o2 sensors and a slight bend to them so not completely sure they’d work yet

It would make sense to me to run dry to the tip than add a decent set of mufflers to take some of the crackle out of it. My bud had a Cig Mistress with dry Gils. Not too bad going down the lake in the boat. But I could hear him loud and clear all the way home for 2 miles from my house to his! His current boat a Powerplay has mufflers (full time) and it is very mellow with no reversion. As long as you have narrowed it down to the risers, that is probably your least expensive options.

What distance did they measure the 93dB?

What Mufflers do you have? Selectable?

Any HP loss with the mufflers on?

Nice paint on the engines.

I believe it is 3' back and 3' up.
Gaffrig switchable. No loss that I recall.

if you end up having to go with new contacts Scott at Speed & Custom Marine (850) 875-0381
I’m sure he can save you money on Stainless Marine products

Why don’t u just have the inner pipe extended so it just about goes through the transom. The hose will act as your outer wall . I have done this a few times for customers that did not to spring for new tail pipes . When they were experiencing reversion .

I have dry CMI. Separate water dumps. It’s loud by anyone’s standards, but I’m not sure it’s as obscene as people make it out to be. 800NA 565’s.

you certainly get used to it, and it doesn’t bother us, but my neighbors and the entire community knows when I’m boating. I will say we rarely run further than about 10-15 miles at a time. We are one of about 3 go-fasts in the area. The other two are fountains with molded platform and traditional exhaust and are considerably quieter.

i will say Helmwurst need to get his hearing checked!! You can hear it for miles and miles and miles. When we leave lunch and run 5-7 miles out of the York River friends have told me they hear me all the way out of the river, around the bend to my house which is a couple more miles depending on wind.

you will make a few enemies, but you will make a lot of kids’ day!!

I have CMI Etops that are dry and dump water right at the end of the tails outside the transom. The water really doesn't mix wit the exhaust. I have switchable mufflers on the ends of the tails. Closing them takes a lot of bark off the exhaust sound at idle and slow cruise speeds. I also close the mufflers when coming off plane to prevent reversion from my own wake

we run the same combo as seaford guy and its pure music we use it as a bad old hot rod to get our thunder therapy never had complaints but lots of compliments old school loud and proud if the Harley guys can say loud pipes save lives so can we!

Ok yall win
 

I think I’m just gonna do dry Risers my next question ( sorry I’m learning here and have a few questions) where are you guys dumping the water that cools them? At the transom somewhere or off port and starboard side? Also another dumb question is there an individual dump for each pipe? Or do you plumb two for each engine into one dump on each side? What did you use? Size , fittings etc etc?

thanks guys I guess she will be noisy but myself likes it so the heck with it haha!

LOL. Yea my hearing does suck these days. That was several years ago when it was pretty sharp. Hearing him for 2 miles was like he was sitting out in front of my house. And we have hills and lots of trees. Love the statement though, my GF says that all the time. I think it is just her octave. Tom FTM has a great suggestion, but I think that takes a pretty good welder/craftsman to do that.

I have seen it done a couple ways, one is individual dumps for each pipe, my buddy (RIP) used to like to put them out the starboard side so you could take a quick look and see the water dump.

Then there is just a small hole in the bottom of each pipe so the last bit of water will run out when the motors are shut off and to keep some cooling going to the very end.

Others put dumps on the transom side and just aim away from the end of the pipes. Still need the little drain on the bottom, we boat in salt here.

You are still running the tails 20% wet, right? You need water to cool the tails and not melt the hose.

.
 

I assume they will still be fully cooled to my understanding but just no water meeting exhaust anymore just getting dumped overboard after passing through riser

.
 

she’s in freshwater 99.9% of the time now. She might see salt this year once maybe if I make it down or get her straightened out this season!

im trying to figure out if I want to go out the side or out the back of the transom somewhere I’m thinking of individual dumps for each pipe but still unsure. What’s a safe hose size? Hole size ? Etc etc etc SM don’t t give me much info

do you really want to drill holes in your boat rather than extending the inner wall of the tails

.
 

truthfully no. But I’m scared spending this 10k just to have the same dang issue

As you have told me before, this boat is a long time keeper, if it was me Id somehow get through this season with as minimal expense as possible, then in the off season plug the trs holes and recut it for the bravo tails which should have been done at the time of the conversion.....jmo

Some tails have the water exit on the outboard side of the transom. Just need to make sure you can clear the bung through the exh hole.

You could extend the tails, making them longer. Inside tube right away, and see how that helps out.

The dams getting repaired would also help.

Can someone explain how this is done? Extending the inner pipe? Do you slip a piece in past the water outlet and then start tack welding it in and let the water flow out past the extension? Any pics of this? Sorry 87 for cutting in on your post.

I'm running dry to tip on my Scarab. The inside pipes were extended to the transom to prevent reversion, currently not running flappers or mufflers. Can still hold a conversation on the boat without yelling and its not super obnoxious around the docks. Luckily where I'm at there are no noise ordinances and the marina I'm at doesn't really care. Dry to tip is more forgiving than dry pipes. If you're worried about it, run mufflers.

As Franks292 mentioned, the inner stainless pipe that flows and contains the exh is extended. It would need to welded. A few options on how to do that depending on how the riser terminates. Easiest is if the inner is already a few inches longer.

^^^^^ I would assume a small weld bead where the extension is welded would not cause the exhaust to do weird things? I mean you are talking a 3" pipe per side.
