I'm with Harry on this one. You have enough stuff to do now to keep you busy. Plus you'll be less inclined to rush through the engine install if you do it going into winter. You can take the time to dress up the engine compartment. It's probably your best bet to minimize lost cruising time.
BTW, I've been working on my Dart on the weekends. I only use a propane torpedo heater and foot warmers to keep warm. Winter really sucks! I'm ready for spring!
