'92 Prostar 205

I've got the muffler that goes across the top of the transmission and its been leaking for some time, but is getting worse, and since I'll be replacing the starter I figure I might as well fix this at the same time.

I need to know where to get some cheap inline mufflers for this boat (cheap being the word because I've already gotta spend quit a bit on the starter). Also can anyone tell me is it 3 or 4 inch inlet/outlet. I'd like something sporty sounding, but not gawdy loud, if I wanted that I'd just put straight pipes in. Thanks.

Already looked there, was hoping to get something a little less that $114 per side. Thanks though.

That is a cheap, as you're going to find. Why would you just, re glass existing silencer?

I did that already once, more holes popped up. I guess I was thinking since you can get an inline muffler for a car for alot less that I should be able to get one for the boat for roughly the same. I guess I'm forgetting about the "marine tax" that is imposed.

LOL, I'd have a ski boat that sounded like a one of the redneck farm trucks around here. If no one has any better ideas by this afternoon I'll probably buck up and get the ones from skidim.

I was looking at these thinking they would be easier to install, and maybe sound a little more sporty without being to overwhelming.

Called Skidim and they said that they sell the most of these

Anyone have any opinions or pro/cons of either of these two.

The OEM dual mufflers in direct drives, in most all cases have the 45 degree end to prevent kinking or bending of the rubber exhaust hose to the muffler from the exhaust riser.

I am using these. http://www.skidim.com/prodinfo.asp?number=288-3001

I do have a set of Mastercraft "Silent Master" (from my 94 Prostar) I'd sell. PM me.

Why did you switch from the stock silent master's in your 94? Are these quieter? I've been looking around for ways to make my 93 quieter. A neighbor of mine on our lake has a CC with a down turned exhaust tip. Anyone ever seen something like that for MC/3" exhaust?

I was trying to make my 94 quieter.

As delivered, didn't make any difference, sound or performance. Then I did the Tige silencer option. I wrapped boat carpet, around the new silencer! ( NO kidding, my brother-n-law's 2005 Tige, has carpet wrapped around his silencers! From the Factory!)

I had already, installed the new silencers, so I added the outdoor carpet wrapped. The "SilentMaster" is a little larger, so don't know, if there is enough room.

That and new motor box insulation, has quieten it nicely. Not as quiet, as new boats, but...Soft rumble at idle (can now hear the radio), then sounds like a proper motor boat--at speed. :cool:

My boat is fairly quiet at idle. Noise I'm trying to address is at the exhaust tips, at speed. Live on a small-ish lake, would like to decrease noise if possible as a courtesy to my neighbors. I may try to the carpet wrap. Also interested in the down-turned tips as I mentioned earlier if anyone has any input on that.

jake, wish you were my neighbor.

To more directly answer your question, and others, there was no appreciable difference in soundl level, between factory/ or aftermarket silencers (water baffle)...at speed from behind the boat. However, much quieter than open exhaust. The carpet made, inside the boat quieter. The SilentMaster and similar design water baffles, are a level between a muffler and open exhaust.

Been thinking about turn-down tips...
From a sound point, it would like standing beside a trumpet player vs. standing in front of the bell. Volume is the same, but it is relative to location of the listener.

Our particular boat.
Issues on fitment,
1) where is the flapper located.
2) is there a possiblity of the turn-down tip scooping water, at low speeds (pre-plane)
3) there are probably quieter baffles(tru mufflers) out there, but space may not be available, in our boat. Then there's price.

You may want to ask a question about using/adapting a silent-tip system, some boats have. In addition to your Silent Master, no clue, on the effects on engine performance. something like these. (this is the wrong size)

Something like this. These are made for a Bu, but thinking same thing for my 190.

Malibu turn down exhaust tips (http://www.bakesonline.com/detail.aspx?ID=756)

Here is another alternative, could put inside, in line after the silencers.

Rex in line silencers (http://shopping.rexmar.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=161103&Category_Code=silencers-inline-insert)

Anyone have experience trying to quiet down an older boat? What do they do on the newer ones to make them so quiet?

'bu option - inlet has to be reduced (Muffler shop, can make a fitting.) Then, there's that water scooping question.(Low speed operation) Looks like 7 to 8" sticking out the behind the hull. So... how high our tips above the bottom of hull, relative to 'bu.

Rex option - these are designed to be, directly after exhaust manifold. Locating in bilge area, below water line, can cause steaming in bilge area. They get real hot. Also, they will increase back pressure.

Found this 'bu on ebay http://cgi.ebay.com/ebaymotors/2007-MALIBU-Wakesetter-Great-condition_W0QQitemZ270424275036QQcmdZViewItemQQptZ Power_Motorboats?hash=item3ef68af85c&_trksid=p4506.c0.m245

Now that, I have seen it installed, probably not a good idea. This was the only boat, on ebay, that had them.

I used the bullet mufflers from overtons and used my elbows from old trashcan muffler cut to fit. I have to see if I can find pics....

that big muffler was the worst design.

Just to follow up.

I did the 42" mufflers from skidim with the angle end and they sound great. I'm so glad I went with these rather than anything else. They are actually noticably louder than the original cross over muffler.
