Can anyone recommend to me the best way rig my boat for a long shaft motor. I have a '60 13 with original notch (15" short shaft). Transom is very firm and very stable. The reason I'm thinking about doing this is that I got a great deal (free) on a 15 hp evinrude. How fast do you think a 15 will push me. I currently have a '78 25 hp evinrude and it pushes me (alone) at about 26 mph (according to GPS). thanks

I believe that attempting to fill in the 15" transom with new glasswork would be a waste of time, and very difficult to achieve. You can readily purchase a 5" or 6" setback transom jack unit that accomplishes the same 5" of lift that you would need to install a 20" shaft engine, and this I would recommend.
It will even improve the performance of the boat. If you don't want the setback, you can also by static lift plates, made of 1/2" aluminium, pre-drilled for engine bolt holes, by Cook Mfg Co (CMC branded products). In either case, you simply bolt on the bracket through existing engine holes, that bolt the engine to the bracket. Makes for a very nice installation without having to alter the Whaler hull. The main reason for doing this is to be able to use a newer 30 or 40hp engine on the boat. I doubt that that you would be happy with only 15hp on a 13. I ran one for a while with a Johnson 18hp, and it would only plane off with 2 people on board.

DMW: I have to somewhat disagree with ISG on the 15 issue. I had a 15 hp Evinrude (1979) on a 1968 13 BW Sport. I had brought the motor in 1980 is was like new for a good price. The whaler was brought with a 40 Johnson manual start. The Johnson was one problem after another, due to age and neglect. And when a 40 manual doesn't want to start it lets you know. In any event I wanted to use the boat so I put the 15 on just as a temp measure. I liked it. It gave the boat nice balance and was very quick. Remember newer motors (1970s on) tend to be somewhat quicker (thru hub exhaust etc...) as oppsosed to an 18 from the 60's. In any event it was a nice performer with two people in it. I would'nt recommend it if you man the boat with four lineman from the Pittsburgh Steelers. Nor would it be good to use to waterski. However, for fishing and light loads (2-3 adults) it performed very well. Another benefit was no matter how much I used it a 3 gal. tank never went empty...... Mark

lhg - I am interested in the static transom lift plates you mentioned by Cook Mfg Co. Do you have any contact information for them? Do you knoe if they have a web page? Thanks

Here are links to two sources and I might add for a few bucks more a manual adjustable jack plate will give you more versatility
