Scubber ???

I inherited two thru-hull fittings when I got mine...be sure the fitting itself is water-tight, leave about 3-4'' of hose, find a suitable plug for hose, insert plug and double clamp w/ stainless steele hose clamps...did mine years ago, w/nary a drop leaked since... ;)...

Different opinions about this, but if that Merc were mine, I'd DISCONNECT the automatic oiling system and pre-mix oil/gas...easily done w/an Accu-Mix bottle ($3.99)...there's some history on those auto-oilers failing, which of course will TOAST your 200... :o...
