It seems to have worked OK for the last 23 years - I wouldn't sweat it!

Good afternoon gents,

I'm the new kid on the block. I purchased Steven Thorne's 34+ about 6 weeks ago and my family an I are enjoying the boat tremendously. 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?

Thanks in advance,

Francois Rivard

And google helped me find out what you are talking about with the latter. Facinating! I wonder if Douglas Adams knew that?
