I don't know if I have a problem or not. Here's the history: boat has been a saltwater boat all of its life until I purchased it last year. First outing this year resulted in a tow back. The port exhaust overheated and burned a hole in the lower rubber exhaust connector. I found that the manifolds and elbows were almost completely clogged with rust. I have replaced both manifolds, risers, elbows, and both connectors on the port side. Testing on the trailer with flush muffs and a garden hose everything seems fine while warming up. Both sides stay nice and cool! After the engine reaches operating temperature and the thermostat opens, the starboard side starts receiving hot water and gets considerably warmer than the port side. I can't say for sure what the temperatures are, but I'll put an IR thermometer on it this weekend. The port side stays so cool that condensation forms on the surfaces and the starboard side gets hot enough that I can't hold my hand on them comfortably for very long. I get concerned about the temperature and shut the engine down. Engine temperature is normal at about 160F. Is this difference normal? Is running from a garden hose part or all of the problem? Could the thermostat housing be rusted through and causing the problem? I plan to drop it in the river this weekend and see if it does better than being on the garden hose.
Thanks,
