Mark, The MC comment wasn't directed to you. In fact, I don't even think about you having a MC anymore. One of these days we'll get you over to a decent boat!

OK Pete......I'm home from the lake and back to wishing I was skiing and boating! I'll assume the comment is just a test to see if I'm paying attention. By the way, I finally found a nice home for those trailer guide pads from Green Lake. They are helping keep a 176 looking sharp on its trailer. |

Gary, The HM's always make the "brapping"!! That's what I used to keep all my neighbors awake with at 3 AM back when I had the 70 Cuda!! (Now I'm at work at 3!!) The good old days are gone.

When I first got mine running, I had replaced all the hose. At wot it made a funny brapping sound,which I think was due to HM manifolds and short 3" hose.Had some short custom mufflers made and now it sounds like glass packs, a nice even sound.

Well I am planning to pull my mufflers next week for testing (assuming a rainy day happens between now and then) and have access to a sound meter but nothing is stock now except the mufflers and I am not going hose all the way back just putting in a galvanized pipe for testing.
I dont know that the pipe vs hose thing is all that pronounced though. My 67 was as loud a correct craft I have heard and it has hoses all the way back. Come to think of it I ran the 83 with the exact same engine and the mufflers it was much much much quieter so assuming it was the mufflers and not the extra 8-10 inches of distance between the engine of the hull I guess I am convinced that the mufflers make a lot of difference at least for really loud engines... |

Me neither. My Tique and Skier sound the same to me- the '78 has the fiberglass mufflers, and Im assuming the '71 does not. No idea if the Skier has copper or straight hose, but Im assuming there are no mufflers under there. The exhaust is still glassed in so I wont be checking anytime soon. |

Honestly, I'm not convinced that rubber hose all the way back is louder than the stock fiberglass mufflers. I'd be interested to do some actual dB comparisons from the back seat, swim platform and 75' back.

Chris, You need to be careful on where you get your information. The people you asked about the muffler may be MC owners!! HW is correct that you better not be asking them for any help. |

The boat is in the water now..as the leak is pretty small. Id like to get this last weekend on the lake before I start. if the leak gets much bigger I have to take the boat out.
I will definetly measure everything..especially because that hose is about as expensive as the Alaskan pipeline per foot |

James,
Check the outside diameter of the mufflers before you buy them. Some are too large to fit between the primary and secondary stringers. |

sometimes the crimp in the hose is because it's actually a shade too long for the space/length between the riser and muffler, might try cutting a 1" or two off of the hose. You can use a piece of tape to make a reference line for where the hose should end relative to the muffler making on the hull/stringer, disconnect the hose, lift up the muffler to get it out of the way and let the hose lay without the crimp on the hull's bottom and see how much of the end of the hose goes past the refernce point you marked to determind how much to cut-off.
Remember you can't added it back once it's been cut so small amounts are better. .02 |

That picture is my boat. Well Mine is red.. but close enough.
Right where the #11 is my exhaust hose has slight crimp from having too sharp a bend. I see that there are mufflers that have an elbow. http://www.jamestowndistributors.com/userportal/show_product.do?pid=9077&familyName=Centek+Verna+Ski+Muffler I will go with two of these, some hose. If the wife will approve the expenditures I may do a set of GT-40p heads and perhaps an intake. I can do a good inspection of the manifolds and risers while I have it all apart. |

#22 is your muffler on a dual exhaust, standard until they changed to the Inverta flow single exhaust system. These bullets are listed as standard equipment in the 77 brochure and I've seen them as far back as 76.

The inline mufflers between the stringers were started in the mid 70's so, the factory mufflers were standard well before 89. Chris, you should do some research and listen to the old guys here!!! I do however agree - who needs mufflers!!! |

74. they had mufflers min still has them... they are under the removable floor.
mufler befor 87 or 88 i think your refering to the other muffler for after 87 the one that goes right after the engine that converts the 2 hose to 1 exhaust. i just can't seem to find a pic edit: foud a pic are you refering to the thing after the engine???? |

Yea 3" for dual exhaust, 4" for single i think. Maybe it was an option, but as far as i Know, the SN's had dual exhaust and straight pipes up until 88. Maybe yours are custtom. IN 89 they switched to the muffler with 1 4" pipe. I say, get rid of mufflers all together. They are only good at night when people are sleeping on the lake! but otherwise, i like to brag about my V8 on the water!!! haha

My 77' had original mufflers, if that is what they were, looked like Cherry Bombs just as Jim describes. Not sure how safe it is but have seen guys use heavy PVC or perhaps Galvanized or Stainless tube? I would guess 3"?? |

I'm not sure that these days that copper is any cheaper.I used rubber all the way before I put mufflers in mine.

My 74 has the hoses off the manifolds, which connect to a copper pipe that runs to the back outside the stringer, then hose to the thru-hull. the copper pipe i am guessing is 5-6 feet long. Not sure though. I am sure, you could run all rubber hose to the back, but it is EXPENSIVE stuff! IF your floor is up. then getting a copper pipe cut is not hard. The hose from the manifold is 22" long. And then 14" for the thru hull to the back of the copper pipe. so, to give an idea of how long.
