You really need to replace the galvanized pipe. If there already is a hole, the pipe is worn out. You can probably make a temporary repair, but view it as short term, like for a week or so.
This past season I was preparing for a week long trip. I moved my boat from my mooring to the dock so I could load gear, etc. When I opened a lazarette I saw exhaust gas in the compartment. Further examination revealed that the exhaust pipe was rotted right at the elbow. I spoke to my mechanic, who confirmed that it would be an easy repair, but he could not do it for a few days. I didn't want to miss the trip, so I used some high temperature epoxy and an exhaust clamp to make a temporary repair. The repair lasted the entire trip, which included over 10 hours of motoring.
When I got back I had the mechanic make the proper repair, which cost about $350. That included having a custom elbow made with the water injection nipple welded on.
