That's all fine and good if you are day sailing. I used to take great pride in sailing my Hotfoot 20 into my slip, but then again you could stop it by just grabbing the dock.

You sound like you take a dim view of using an engine...so tell me, let's say you decide to go down to Saltspring Island one fine summer weekend....and there is almost no wind. Do you ghost along at 1 or 2 knots all day' what do you do when you want to get through a pass...Porlier or Active Pass perhaps? There is still very little wind, and you've spent the better part of the day getting there. Hopefully the timing worked out and the current is going your way. Do you just let yourself get flushed through like so much flotsam? Now, you are through, and if there is very little wind in the strait, there could be zero wind in Trincomali. What do you do then?

Saying "people who use engines are making a boating choice" tells me you dont venture very far from home, because around here there are plenty of days in the summer where there is no wind at all, and you will never get far if you don't motor. Yes, it is a boating choice....it is the choice between drifting all day and getting nowhere, and actually travelling to a destination.

Ask cruisers how often they actually get to sail in Desolation Sound....

Re: Rebuilding the Volvo MD7A

ShockT. Don't get your shirt in a knot. I don't disagree with you completely. You are now talking about motoring through swift flowing channels and making it to a far away island. In your original post you said you needed to motor a lot. Of course I will motor against a strong current and perhaps even the last couple of miles after a long day of sailing. But choosing a far away destination on a light wind day is a choice. Insisting on sailing faster than 4 or 5 knots is a choice. Answering your final statement, we go to Desolation Sound every year and we sail the majority of the time. Decent wind, have a great sail. Light wind, get out the gennaker and meet the challenge. No wind, stay put and do something else. Or turn on the motor. You have a beautiful boat and how you use it is up to you, but sailors in our area do not have to motor a lot.

Well you must be very lucky with your choice of vacation days. We went up the sunshine coast last year and out of the 10 days we were away it was glassy calm every day except 2. We have crossed the strait many times in glass calm conditions. It's either motor or don't go.

We have to motor far more often than we would like. Maybe once I retire I will have the luxury of just staying put if there is no wind....

Regardless, back to the original subject...that is why I don't think electric propulsion is practical on anything but a day sailor around here.

You can look it up, but it seems to be consensus.

The tolerances in this kind of engine are completely different from modern engines, and the old one might not be happy with the modern oil.
I know it sounds counter intuitive.
Ill look into this more. It just so happened I have that oil leftover from my change oil for my truck. And I've used synthetic oil on all my cars old and newer, just a habit I guess.
