Suspected Exhaust Leak
At the end of the 2016 season i noticed the cabin was filling with smoke while I was motoring to a marina to get bottom painted. I figured that it was due to the growth on the hull and prop adding load to the engine. When it was completed and I tweaked the idle setting, the smoke stopped. I didn’t use the boat much last year, but it smoked again by the end of the season and again this year. I had the bottom cleaned, but still smoke. After looking at the engine I determined that the smoke was coming from the exhaust tube from the engine to the muffler. The smoke is white and it lingers with a gas like smell. My thought is to replace the exhaust tube. I have attached a picture for reference.
Any troubleshooting thoughts? Also, where is the best place to buy the tube? Mine looks different than other options I have seen (1979 Catalina 30). Thanks!
