Question to those with sail-drives, have you ever had a leak detected??[/quote]
I have owned my 22 1/2 hp 3 gm with saildrive (sd20) for 25 years, never had a leak with original 2 seals
still in place. (tried to convince my Yanmar dealer they should be changed, he says he has customers with
older seals still going strong).
Upper visible seal looks new and I check it often as it is
very accessible. I do test my water sensor that lives between the 2 seals (unscrew sensor and dip into cup
of water and the alarm light should go off if working).
There is a third rubber protection piece that attaches to the outer hull and goes around the saildrive leg, this is not waterproof and keeps out unwanted barnicles and growth.
Install in monohull seems very safe as the saildrive
lives behind and thus protected by the keel.
Cats with saildrives are a bit more exposed.
