Hate to admit it, but I've been paying a marina to winterize Endless Summer the past four off-seasons... something that I'm CERTAIN I can do myself, but just been too timid to try it. Many of my boating friends simply run antifreeze through the engine block instead of pulling all the plugs to drain the water out. I'd prefer to do the same thing, as Endless Summer is stored under-cover during the Winter months, where we occasionally get temps down below zero farenheit for a week or more (Spokane, WA area). I have no problem doing my water system (galley, head, transom shower) it's just the engine that "scares" me due to the consequences of doing it wrong (cracked block, etc...).
If I could do this myself every Fall it would be a HUGE load off my mind every year, not to mention the savings. Overton's has a "Do-It-Yourself Winterizer" for $49.99 that flushes antifreeze through the engine by way of the outdrive pick-up/"ear-muffs" coming from a 5 gallon tank that's gravity-fed (http://www.overtons.com/modperl/prod..._holder)-----I
do not have a closed-water system, water is picked-up through the B-III outdrive to cool the single 6.2L engine. Has anyone had any experience doing this? I think I can ALSO pump my own oil out of the engine block with a friend's oil extractor by myself... it's just the draining of the water/flushing anti-freeze that's got me intimidated.
Considering all the projects I do on Endless Summer, I should also be doing this and of course the Summerization in the Spring. If anyone has experience with this, please chime in!
