Hello, I have two questions related to my 1984 M-17, Seaweed. 1) While sailing Lake Michigan on Sunday my original wood rudder cracked. The crack is about 10 inches long, and starts at the top of the rudder, going vertically down the middle of the rudder. It is just a crack in the wood, and the rudder is still in one piece. Should I try to fix it, and if yes how? I was thinking of putting a wedge in, then filling the space with 3M 5200, removing the wedge, letting it cure clamped down, fiberglassing the whole top of the rudder (it is not under the water), and repainting with Cetol. Would this work? The other option would be to buy a new rudder, either a wood one (does Bob sell them?) or an Ida Sailor one. Any recommendations on one over the other? 2) I was thinking of replacing the 2 stroke 4hp Evinrude I currently have (original 1984 issue) with a 4 stroke motor. To be honest I don't quite know why, since the current motor does a great job, and works every time. In the process I bought a Tohatsu 4hp 4 stroke short shaft motor for $500, but found that with the current fixed motor mount it does not reach deep enough in the water. I can replace the mount with an adjustable one -- does anyone have a recommendation for a good mount, and comment on how hard it is to install? Or else I have found someone who sells a 6hp Tohatsu long shaft for $750 which would do the trick in terms of shaft length (and I could sell the 4hp for what I have in it), but I have read some negative comments on it. Does anyone have any experience with either of these two motors? Thanks, Andrei.
