Hey Dave,
Looking good! I'm really enjoying and learning lots from this thread. Looks like you will be getting Denny out before he gets up to Nova Scotia this summer.
If you ever get a cold snap and are concerned that the shop vac has not sucked all the water out, just put an incandescent light bulb in the engine compartment. I use a trouble light with a 60w bulb. It gives us a few extra days on the water in fall Pickerel fishing season, although, I have a hard time believing it would get cold enough down there, to snap those pipes...but you never know, with this crazy weather we're getting these days.
I guess you'll be putting that spa up towards the bow somewhere?...
Keep up the great work!
Brandon
