Getting ready to replace one side of my exhaust hose on by 86 2001. Is this a big job? Can someone who has actually done this give a shout. I ordered new hose from C.C. As always thanks for your help.. ------------- starbucksdad |

it's really not a hard job just can be a PITA getting the hose loose from the thru hull fitting, usually you can get back to them using a 1/4 drive ratchet to remove th clamps then if they are glued on pretty then just cut it at the flange since you replacing it. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

| I just did the job. I took my gas tank out for other reasons and that really helped. Like Chris says, making it form to the S shape was a PITA. I even tried warming them with a hot blower. Since I had the tank out I replace the hose connecting the muffler with the stern. I was glad I did. To make things go in easier I used silicon lubricant and soap and water. I left the clamp out of the stern thru exhaust so I can move the muffler up and down a little bit. With the hose attached to the manifold with the clamps, I raised the muffler and placed the hose on muffler as close as I could. Then I pushed down hard until the muffler got into its place. The S shape came out perfect, IMO. I measured a ton of times to make sure I had the right length. I believe I used 3' for the front and 6" on the back. Also, I put double clamp on all of the connections. If you can't wedge it in then get somebody to step into the maifold connected hose. Once is down push it forward. This might work. I bet other will share their experience. Having soap water really helped. |

BTW Chris, in another thread you recommended an MSD 8222 Coil. Well, for a while I have been pulling my hair because my boat was dying all after it was warm. I used the coil you recommend and the boat is running great, 45mph WOT. I also replaced the resistor with the one they recommend. Problably I didn't need to but I decided to do it anyways. Anyways, thank for the advice. |

I've used a couple of little tricks with the exhaust hose. For starters, get the right kind. What I mean is straight hose won't make much of a bend without kinking so the engine to muffler piece needs to be corrugated in most cases. Also the lengths will be a bit different from 1 side to the other.
With new hose, I found it pays to mount the hose to the muffler and weight the engine end and let the sun do some of the work. Also, I put everything together(both hoses on each end of the muffler) and starting in the middle of the bilge, it will tend to 'roll' onto both fittings. ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

be sure and get wire re-inforced hose if you didn't send it back and get the right stuff. Both need to be wire re-inforced hose otherwise you risj it collasping on you, stright for the back and corricated for the front like suggested all ready. Start at the transom and move forward, this will allow for the hose to lay in it's natural position against the manifold for easy length determination, just route it to the inside or out side of the riser and mark and cut to length. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

OK guys, all of this is fine and good, but I want to take the mufflers completely off of my 87 Riviera 454 and run straight hose. I have really gotten into it, ie taking up the floorboard behind the motor box to check it out, but it sounds like there are hoses already to the front of the muffler and then a short hose at the transom pipes. Given this it seems that two short piece on each exhaust of the proper stainless pipe into the existing hose might be a way to do this ( put the pieces into the new hose replacing the mufflers prior to slipping them on ). Like everything else related to something that seems like it should be simple, I am sure that it is not. Suggestions? ------------- "To profit from good advice requires more wisdom than to give it" |

crossover pipe? ------------- "the things you own will start to own you" |

Shouldn't need a crossover pipe since it doesn't have one between the two exhaust pipes now. Good idea, but trying to keep this simple. ------------- "To profit from good advice requires more wisdom than to give it" |

I haven't seen the exhaust in a martinique, but I bet it's the same as mine. You need a short(12-18"?) piece of straight wet exhaust hose to seal onto the hull fitting, and a longer piece of corrugated hose to make the bend to the manifolds.
Then just replace the mufflers with the stainless pipe. Disclaimer-I haven't done this with straight pipe, but I have done it several times with mufflers. ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |
