Does anyone know how the exhaust was originally routed on the 36? Did Gulfstar use waterlift mufflers? In particular I'm interested in knowing how the port exhaust was run.
My 4-154s have a 2" diameter elbow with 4" diameter hose connected to them and no waterlift. On the port side the hose runs under the aft head on it's way to the transom creating a low spot under the head where (too much) water collects after the engine shuts down. The hose is crushed in some areas so I want to re-do it, probably with 2". The exhaust is barely at the waterline so getting a downhill run especially through the aft head appears to be difficult if not impossible without waterlifts but I can't figure out where to mount them.
Thought it would be nice to start with the original design but can't find info on that.
