Figured out exactly which hoses and plugs to replace in a 6 cyl I/O Cobra and took it out for a chilly high-speed shakedown on Sunday. Basically a 15-minute evolution to drain it or plug it. So now I can do it myself whenever I want to - and not "put it in mothballs" for 5-6 months every year. Grew up here but never owned boats until I lived in San Diego for awhile. Didn't cover (or winterize) them there. So the whole mildew under the tarp thing is new to me now that I'm home again and boating in the NW. I'd hate to see mildew take a strong hold. Did a LOT of scrubbing last spring with a cup of bleach in 5 gallons of water. Is there anything quicker you guys recommend? Thanks in advance for tips.
