Attach a few pics of my CLAE Fisherman 6.
The one (new in a crate in the 90's ?).
Thanks Laurie for your response.
Newly painted and a new (replaced )stainless steel exhaust cooler.
I've replaced the outlet hose from the exhaust pipe with what I thought was good rubber hose however it now smokes and burns at the joint although previously it was OK. Same amount of saltwater coming through.
Any recommendations for alternate joints (asbestos is out)? Or do I need better rubber hose ? Theoretically replacing what was there.
Also had a new shaped s/s pipe made but it still has to be connected by something taking the heat.

Could be hose, is it a lloyds rated hose?
Or could it be that the exiting coolant water is not introduced early enough into the exhaust system or at the correct angle or height.?
I can put my hand on the exhaust pipe where the cooling water enters on our P55, but years of owning and running a Stuart has made
a mess of my senses.

Explain the two hoses going into/out of the muffler assy.Are you just cooling the muffler with a water jacket only? And not putting cooling water into the exhaust gas,it looks like the cooling water is coming out of the head the into the rear of your muffler,out of the muffler to ???? If you do not
have any water in a rubber exhaust it will burn no
matter what rubber you use.So you will have to use a fully lagged metal system.

I agree with Todd.
Looks to me as if your outlet hose needs to be placed in the elbow above your rubber joiner piece.
Just my opinion.

Yes the water jacket is not really a muffler .Need and love the putt putt sound .
One hose feeds from the engine into the bottom of the jacket, filling it and then passes out through the hose on the top .This water then meets the exhaust gases just as it passes through the hull to exit. It is luke warm at exit and the jacket stays very cool.
I understand all the contributions .Thank you gentlemen .What I can't understand is why it worked with rubber hose before I replaced the pitted S/S water jacket .
Have had a new shaped s/s pipe made to replace the full rubber hose but I still have to 'join' it to the jacket and I also need something flexible between the motor and the through hull outlet to arrest vibration etc.

You're right Paul,
The boat is moored on the South Coast of NSW.
Guess I'll have to unbolt the system and bring it to Sydney and have a new fitting outlet pipe right at the 'hot spot' making sure it is low enough no to suck water back.
Thanks again lads .
