The Aqua Lift system is as (or more quiet) than the original cumbersome “Rub Goldberg” Ericson factory installed standpipe.
…More importantly, it is STILL going strong as ever, yet today, after having been installed way back in ‘91 or ‘92 when we installed our then new diesel!
FWIW, when I replaced the OEM water lift muffler in our boat in 2018, because the hose size was different for the new engine, the old muffler looked barely used. Those are a fiberglass/composite construction, and unless you have a failure in the raw water pump and run some straight exhaust thru them and overheat or melt the material, seem to have very long life.
Loren, as always, GOOD POST!
FYI…For many of us now - WAY - older Ericson’s from the early 70’s, the so called muffler was but a simply designed upright (standpipe) wrapped in (of all things) multiple wrappings of the then legendary anti-fire miracle material of asbestos.
…Ericson even once sent me a standpipe update kit, of sorts, that included another lengthy piece of asbestos wrap …long before the hazards were realized of course!
(Today, when looking back, the USPS would go totally spastic with such a mailing!!! ;-))).)
Ericson certainly had come a long way over the years with addressing these issues. …Yet, for those of us now (can’t believe it) old time owners, or - the new ones of older early 70’s boats; replacement issues abound be it of practical, monetary or optimal concerns.
This IS a good/GREAT thread for said conversations of experiences and solutions for all of us. I feel mine were resolved with the “Aqua Lift” system but am anxious to hear of others’ experience/solutions.
