I have an MD22 in my Cromarty 36 motorsailer. It ran perfectly for 20 years, until recently I started smelling burnt rubber whenever I rev the engine over 3000 rpm. The smell comes out of the exhaust pipe. This winter, I have put a new water manifold (not sure if this is the correct term in English, but it's part nr. '7' on the drawing) before the exhaust, I have changed the impeller and I've renewed the distribution belt.
I presume the smell comes from the rubber exhaust hose heating up at high revs. But this was not the case before. What can be the cause? And is there a risk of fire?
