Riser elbow

[Denis]

As a result of a thread here a couple of months ago, I removed the exhaust riser to check it for soundness on Saturday. It came off easily and I found out it was made of aluminum not cast iron. It really did not show any wear but since I do not know how old it is and it was on there when I bought the boat four years ago it's worth a change. It's also a good time to change the rubber hose that attaches it. I also want to pull the heat exchanger and check that, I'll let you know how that goes. Denis

Denis,
Did you ever pull the exchanger? I'm interested in the results. How many hours on your engine?

I did install a new exhaust elbow, it costs just under $200 and took about a half hour to change. I ordered two new gaskets for the exchanger but I have not taken it out yet to check it. Not to make an excuse, but I am rebuilding a house from the ground up right now so I am putting a lot of hours in on that. In another post I mentioned that I only ran 30 hours last year, I'll be lucky if I put 20 hours on her this year.
