My
1987 model 17 has the same measurements, Bill &

Tod
I just measured skeg on my 1975 M-17
(#55). The width at very top where it meets hull is 2-5/8 inches. The width at
bottom, before it starts to curve is 1-3/8 inches. Coincidentally, I just pulled
it out of water. I think that you will find differences between years.
