Hello everyone, this is my first post that involves a question about the design and installation of a motor well in a Grand Banks style dory. I'm a genuine dory fan and owned a 20' Lowell sportsman (should have never sold that boat ) before my current 18' banker. The Lowell had a motor well that included a slot in the counter that allowed full tilt of the outboard for beaching. However, it eliminated a lot of displacement at the stern.
My current dory, constructed with care by a fine older gentleman in Newfoundland does not have a motor well, but the transom was made wide enough to accomodate an outboard. I bought a 9.9 HP Honda with an extra long sailboat shaft (28") and fabricated an aluminum bracket to mount the motor vertical. Unfortunately, this seems to be an unsatisfactory arrangement. The boat squats terribly to the stern and a tiller extension would have to be about six feet long to properly balance the dory!
This brings me back to the subject of motor wells. Had I known better, I would have had one built in from the start. I've got John Gardner's Dory book and it does briefly cover some issues, but not for my application. I would be very interested in the thoughts of boat enthusiests on this forum.
1. How can one design a motor well that allows tilting with MINIMAL displacement loss?
2. Is tilting required at all? I've got a couple other outboards right now that are light enough to easily be lifted when required. One is a 2 HP honda four stroke 15 " shaft and the other is a 5 hp Nissan four stroke with a 20" shaft. As everyone here knows, horsepower isn't really an issue with this style hull design so perhaps a smaller motor would be better if the smallest size motor well is the goal. The question is with a minimal motor well, what happens if you hit an underwater obstruction? (I'm not really worried about damaging a motor, but I don't want to find myself sinking in 36 degree Michgan water in November )
On the other hand, a two cylinder outboard is MUCH smoother compared to one cylinder "thumpers." So, if I'm going to accomodate the sewing machine smooth, but much heavier Honda 9.9, there will have to be some sort of a tilt arrangement. Any ideas?
