I'm sure this has been asked a thousand times over, but here's my situation.

I have an 89' 9.9 electric start evinrude 2 stroke long shaft, I’m still in the process of finding a 12 foot aluminum boat to put it on, so no boat yet.

I ordered a new short drive shaft and shift rod for it but the drive shaft seems to be on back order with no word yet of a ship date, the parts place I'm going through says ..."who knows when it will show up"

My idea behind the short shaft conversion was because most all the 12-foot aluminum boats I've looked at take a short shaft.

So my next question would be, if I can't get the short shaft for the conversion on the outboard, what about a jack plate? I've done some reading on the subject and am seeing some good things said about using a jack plate, with better performance, less turbulence, ect, ect. But is that something that would apply to a little 12-foot boat and a 10-horse motor?

Am I going to gain anything by leaving the outboard a long shaft and installing a jack plate to raise the motor, on what ever 12 footer I end up with, or am I maybe putting the horse before the cart if I haven't got a boat for the motor yet? who knows, maybe I'll get lucky, and find a 12 footer that takes a long shaft although I tend to think that something like that would be hard to find.

I really don't want to trade off the motor for a short shaft, mine only has 15 hours on it and still looks brand new, so I'd really like to use what I already have.

Re: long shafts and jack plates

i just made this jack plate, had fabricator bend 3/16 aluminum, and built wood mounting plate. $50. this was so i could mount a long shaft 40hp on my 1956 duracraft.
