Air cooled engine with wet exhaust?
My girlfriend and I recently invested our lives and money into a sailboat. Our goal of cruising towards Cuba has unfortunately come to a bit of a standstill as some of the current realities with our boat have made themselves seen.
We are now in Beaufort, SC - and time has come to make some tough decisions. I would hate to say stuck, as it is a wonderful town!
The boat is a beautifully crafted George Buehler steel cutter. Not just a home build either - done by professionals at a boat yard. We are still very happy with the purchase. Incredibly solid - built to face almost anything. BUT, there are some quirks that need to be worked out before we can move forward.
The main one being our exhaust system. We have a Deutz 303-1 air cooled engine. Everything I have read and researched about Deutz engines has been positive. It is a little bit underpowered for our boat weight - but nothing that cant be managed. All in all - the engine is in great condition, runs really well, and I'm happy with it.
Unfortunately, the show stopper at the moment is the exhaust system that was coupled with the engine. A dry exhaust runs to the stern of the boat. Whoever installed the dry exhaust seemed to have known what they were doing - but it seems to be a poor match with this engine. It is a rather long (too long) system of flex pipes, metal tubing and muffler. We are not happy with it at all. The engine is a bit of a beast, and as a result, the exhaust system rattles and shakes. Rattles and shakes to the point that leaks have developed. We dont think this a problem that can simply be addressed by getting new parts. I'm convinced that the fate of the new parts will be the same in the long run. My opinion is that we will need to switch to a wet exhaust.
I'm wondering if any of you have experience with, or thoughts on matching an air cooled engine with a wet exhaust. The main concern I have is with the length of the exhaust system. In all, it is just under five feet in length, and from what I understand of wet exhausts - the shorter the better. We have no above the waterline seacocks on the port and starboard side of the boat, so the exhaust pretty much has to go out the stern.
We would love to keep the momentum of our trip going.... but things need to be dealt with.
ANY help would be much appreciated.
