I am getting ready to replace the exhaust hose on my Yanmar 4LHA-stps. The current set up is a continuous run of 4" with wire from the elbow to the muffler.
For various reasons, I'm going to change it up a little, going with about a 7' run of hose to a 4' long piece of fiberglass exhaust tubing to a 1' section that goes through the aft bulkhead of the engine room and connects to the muffler, which is in the lazarette.
There will be a gentle curve in the 7' section as it drops from the elbow down about 2 feet to the tubing. The fwd end of the tubing, very close to the connection to the hose is supported by a cradle. There are no hard bends.
If possible, I'd like to avoid using the wire reinforced hose, mainly just because it is easier to work with. I'm sure I'm going to use no wire for the small section that goes through the aft bulkhead as that connection is going to be a tough one to do.
What do you guys think about no wire for the long section?
