After my 1978 Johnson died all at once today, I've decided to re-power my 13-foot 1968 Boston Whaler. It takes a 15-inch shaft outboard. What manufactuers still make a 2 stroke in 25-40hp, Remote steering, not tiller, with a 15-inch shaft? Any recommendations on the outfitting process or any info you find I should know will be greatly helpful! Thank you all, Ben

There may be others, but Tohatsu makes them, and offers T&T as an option. They are also marketed as Nissan.

I believe the 2-stroke Johnson 25 and 30 can still be had in 15 inch shaft lengths.

There are a lot of choices out there. Here are a couple that I would look at.

You might try for short shaft motors. I got my 30HP Yamaha from them with no problems. Dave

I think you will be disappointed to find that all of us owners of the older 13's are just about out of luck in re-powering with a new or late 40HP outboard. Honda doesn't go there, and mercury only goes there with a tiller model. The retrofit makes the cost prohibitive. I have just recently tried to go down this road. I guess I will just have to optimize my 1985 merc as best I can. You can go down to a 30 by some manufacturers, or a 20 or 25, but no 40's.

I just looked on Johnson's current Web site and they list the 40 HP 2 Stroke engine with a 15 inch shaft....

I think I'm just going to go with a Johnson 30hp 2 stroke engine with hydraulic steering. That way I dont have to replace any of the fuel tanks I have, drill any new holes(Right?) and I like the 2 year warrenty offered and the 117lb weight of the motor. Now all I need is a place to get it...Thank you all and if anyone has this setup or a similar one with a 30hp, please lmk how it preforms. Ben

The Mercury web site list the 40 as available in 15" tiller or remote steering. No retrofit involved.

[Changed TOPIC; was "Outboard makers still making a 15'' shaft motor in 25-30-40hp? 1968 Whaler 13ft"--phew, that was longer than most of the answers!--jimh]

Thank you all for the input. I hate it when you go to multiple dealers and they all tell you they can't sell you what you need. Best guess is they can't make a pile of money off a special order so don't want to be bothered. I just forwarded the link to the merc 40 classic over to a marina about 400 miles away to see if they would be willing to help me, since the locals won't. But then, the locals are married to alumawelds and miles of camo.
