Sometime ago I saw a really cool saildrive
modification on this site that I'm considering doing. I am hoping to get some good input or reasoning as to why I shouldn't do it, before I do. Hopefully the guy that thought of it and posted it, will tell us how it worked out in the long run.
Next to regularly cleaning
the raw water
intake channels in the saildrive
, the next worst thing is when the lower seals
fail and sea water
mixes in with the oil
. Necessitating immediately hauling the boat to replace the seals
I saw a blog here a few years ago where someone installed a radiator overflow plastic tank just above the water
line and ran a hose from the tank to a male hose fitting that replaced the dip stick on top of the saildrive unit. The head
pressure from the 90 weight oil
in the overflow tank, mounted just above the water line would STOP the seawater from intruding into the failed seal and conversely send 90 weight oil out, before the seawater came in. Given the viscosity of the oil, very little if any would ever leak out, but will block the seawater from EVER coming in.
Seems like a "No Drainer" to me and very inexpensive to do. Much less money
than one haul of the boat for an emergency
