Pete, I thought thats what you might have been thinking- but the corrugated stuff (both 3" on the Tique and 3.5" on my '90) that Ive installed recently are corrugated on the outside only- the inside is smooth, just like the hardwall. This was a question I asked before purchasing- I wouldnt stand for a loss of flow! |

Tim, I certainly understand you wouldn't want any losses in flow and glad to here you found a hose with the smooth ID. It must be a intermediate hose between the hard wall and the corrugated I've come across. Speaking of flow, wait until you get up to my age!!

I have a pinhole leak where the two halves of the muffler were fitted together with some sort of sealing bead of caulk. What kinda caulk should I use to reseal the bead?

Roy, First I would try to pull it apart so you can reseal the whole joint. If one spot is bad, chances are the rest of the joint is ready to go. Are you sure it's caulked? For caulking, I would go for the 3M 5200 adhesive sealant. It sticks to almost anything and is rated at 190 degrees so I feel it would handle the heat.
Has the boat ever overheated? |

I dunno Pete- both hoses were advertised as regular corrugated hose, and they came from different sources (SkiDIM and White Lake). |

It overheated once about 10 years ago which resulted in collapsed exhaust hose. This round the rear hose past the mufflers was bad so I just decided to do it all. The muffler seems to be 2 halves that are slid together and a brown sealant was used where they slide into each other. Im thinking 5200 as well.

Good info in this post, I am getting ready to do the "lose the mufflers, run straight pipes" thing on my 87 454 PCM Riviera. Will advise as to what I run into!

AGGGGGHHHHHH! Not an easy thing to get those mufflers off and out! After all of the removal of stuff to get to the front of them, and following all of the good advice on breaking them loose from the hose, all I managed to do is "break" them, yes they are actually fiberglass, not metal, so today the cutter is going to work to just cut them out and then pull the remaining pieces out of the hose. Got to take the gas tank out, or at least move it, to get at the rear. Probably should repack the driveshaft and rudder while I have all of this stuff out of the way, huh.
