I like systems to be as simple as possible, but I wanted to know if there was some issue with standpipes that lead to them being replaced by waterlifts. Now I think the reason is head space for a standpipe, which is not an issue in my boat.
I really don't like the issue with waterlifts of them filling with water when you turn the engine over without it firing and then they fill up.
Non-water cooled exhausts are extremely dangerous for a variety of reasons.
However if the run internally is short and lagged properly..they have been safe and successful since the beginning of internal combustion engines.
Buehler suggests many things that are borderline issues with insuring a boat....many surveyors (right or wrong) will make note of things that insurance companies will follow blindly...and I feel Buehler's back yard boat concept is to have inexpensive boats that he might not even consider insuring ( I did have his book for decades).
Sorry...didn't associate standpipe with water cooling...been awhile since looking at home-built or other old timer stuff.
