Re: Stus-List 1 1/2" ID Exhaust hose
Francois, I replaces the exhaust system on my 1987 35mk3 a few years ago, and based on that here are my comments: 1. of course the mechanic is going to yell at you, because 1) he cannot be on record as going against what his manufacturer is publishing and perhaps 2) he wants you to employ *him* to do this job. 2.I think *part* of the current school of thought on going to 2" has to do with muffler availability. 2" inlet and 2" outlet is pretty normal and easy to purchase muffler size. 2" inlet and 1.5" outlet is not. For me I could only find it as a very pricey special order. And you don't mention if you are replacing the muffler. Mine (which was the same age as yours is now when I replaced it) was starting to rust out and needed replacement, in addition to the cracks in my exhaust hose. If you have the hoses out (one of the harder things to do in this job), you might strongly consider replacing your muffler. Unless yours is already non-metallic. 3. the problem of going "under" the fuel tank can be solved by going "over" the fuel tank. That's the route mine goes. Out of the top of the muffler, with a gentle curve to horizontal and over top of the fuel tank, then sloping down to the hull fitting. Yes, moving to 2" means perhaps going to a 2" hull fitting, but that's not soo bad. The old fitting is 23 years old. Why not replace it? And boring the hole out to 2" from 1.5" is easy with sanding drums and a few hours of time. I chucked a 1.5" sanding drum into my hand drill with 60 grit paper, and a few sheets of sandpaper and some time later, had a 2" hole. Easy peasy. -Keith M C&C 35-3 Beyond the Sea. -Original Message- From: Jean-Francois J Rivard [mailto:jfriv...@us.ibm.com] Sent: Thursday, August 22, 2013 5:17 PM To: cnc-list@cnc-list.com Cc: cnc-list@cnc-list.com; CnC-List Subject: Re: Stus-List 1 1/2" ID Exhaust hose Good afternoon gents, I'm the new kid on the block.

Re: Stus-List 1 1/2" ID Exhaust hose
I appreciate the prompt responses and I'm glad we all feel the same way. I researched it over at the 34/36 Google group ( I just discovered the group. Thanks Chuck ) and all concur there as well. The boat came with 1 1/2 ID hose, C&C designed it that way, and Yanmar approved. I would think it's safe to say that both of those organizations probably had a pretty good clue on how much exhaust throughput a 900 cc, 24HP, 3 cylinder diesel really needs. If it ain't broke, why fix it? Francois Rivard 1990 C&C 34+ WK "Take Five" Cumming, GA___ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com

Stus-List 1 1/2" ID Exhaust hose
Jean-Francois: My boat came from the factory with a 1 1/2" ID marine exhaust hose. Due to signs of deterioration, I replaced it last year with a 1 1/2" ID marine grade hard-wall exhaust hose. My engine is a Yanmar 2GMF and works fine...it is nnow almost 30 years old. While a 2" ID hose might be recommended, I don't believe your engine will be harmed with the 1 1/2" ID hose. I am not switching up to the larger hose. Bob Abbott AZURA C&C 32 - 84 Halifax, N.S. On 2013/08/22 6:17 PM, Jean-Francois J Rivard wrote: Good afternoon gents, I'm the new kid on the block.

My Perkins 107 had a 1 ½ exhaust, never a problem. The new Kubota had a 2 5/8 elbow, I came out of the lift with a 2 hose, and did change it, but I doubt I would have ever noticed a difference if I had stayed with 1 ½ These things do not have a car type muffler that increases back pressure, and really, they are little engines anyway.

I've also been busy waxing and cleaning as well as fixing a bunch of little things that needed attention. My question is : Is it really such a bad idea to replace the original 1 1/2 ID exhaust hose with an identical hose? (And not going to 2" as per the " current school of thought" ) Prior to purchase, The surveyor noted hairline cracks at the loop before discharge with some evidence of very minor leaks. I finally got around to disconnecting it and wrestling it out of the boat. It appears to be original with and internal diameter of 1.5 inch and 12 feet in length. I checked with my mechanic to see if he had one on hand and he scolded me for even considering replacing it with another 1.5 inch diameter instead of the "Prescribed" 2 inches stating that I was killing the engine with excessive back pressure. The thing is: This boat is clearly designed for a 1.5 inch hose. The stern discharge exhaust through hull is molded as an integral part of the hull and is 1.5 inch in diameter. ( I saw it during the survey while the boat was out of the water). Also, there's no way a 2 inch diameter hose would fit between the bottom of the fuel tank and the hull where it runs from the muffler to the stern. To get a 2 inch hose through you'd have to lift the tank and squeeze it back in place while compressing the hose. There are no hard bends or kinks, it's a straight run to the loop before the integrated hull discharge The engine runs fine, the boat makes 7 knots at 2,800 rpm's or so and get up to hull speed (about 7.5) when you give it full throttle for while so for all appearances, it's making all the power it's supposed to make. All this after 23 years of "being killed" by back pressure. I might consider reworking the exhaust situation this winter when she's on the hard for a bottom job but for now, there's no way I'm missing on precious weekends on the lake with the family for a very remote possibility of an issue with this. Am I taking such a risk?

Now the question in my curious geek mind is whether you've read the Hitchhiker's Guide to the Universe, you know a lot about General Relativity, or both?
