crashkahuna, as a surveyor
I am obligated to tell you that the reinforced PVC water hose on your wet exhaust is a danger
to you and your boat. If the vessel is afloat and the seacock is not closed, IMMEDIATELY CLOSE YOUR ENGINE'S RAW WATER
INTAKE SEACOCK, AND REPLACE THE PVC HOSE WITH APPROVED MARINE
WET EXHAUST HOSE BEFORE STARTING YOUR ENGINE
AGAIN. I also see other reinforced PVC water hoses in the picture, if they are part of the engine system then also renew those with approved hoses at the same time.
Replacing my engine's exhaust elbow is so close to the top of THE LIST that I'm already looking into it. Given that this part is doomed to corrode, and that a failure has the potential to sink a boat and kill people with CO poisoning, I do not understand why replacements
are not readily available. Nigel Calder usually has good advice and in his Marine Diesel
Engines book he says that, "The elbow is frequently custom-made and hard to replace, so you should inspect it annually and carry a spare on board." Given that it looks like I'll have to fabricate my own exhaust elbow I intend to make two. If it is really fun I'll make three.
The main reason I have not considered stainless is the issue of drilling and tapping a hole for the water injection nipple - George how did you handle that part of it? What grade stainless did you choose?
