great deal

those are great running motors

Yep. Great motors. I've got 3 of them (well, if you count same year and model Evinrudes, which aside from paint, are identical). 2 long shaft, 1 short. The short shaft is going to be up for sale in a few weeks, if someone is interested. Electric start, remote control.
 
Just checking to make sure it was a true 40hp at the prop.
Thanks.
I have had a 40hp on my boat before,only a 30hp now...
kinda missing the 40hp.

'Tis not a 40 at the prop. Didn't start rating them there until around '85. That would be a 40 at the crank, and while I've never dyno'd any motor to test it, supposedly, outboards loose about 10% between the motor and the prop. So, I would place this one with a modern 35. Maybe a hair lower, as it is a 35 year old engine, and obviously not 100% on compression and such. All being propped right, I could probably be beat by a modern 35, but I bet it would be a close race. A modern 30 probably wouldn't beat me.

However, if you want a very reliable engine, that will take a licken' and keep on ticking (with the exception of a real large rock at WOT :roll: - when will USPS get here with my gearcase?), that motor can't be beat.
 
Just read your post....
I didn't pan out.
Went to see it and I thought in the picture I could see a tiller....nope.
Electric start,spare prop and controls went with it but I like a tiller model had to say no.
There will be other ones and seeing as i don't need another,I'll just keep looking.
 
Converting that engine to a tiller is a breeze. You would need the tiller handle from a donor engine and the shaft/gear assembly that goes from the handle back to the vertical throttle shaft gear. Just about everything from the late 50's will fit that midsection. Just did a conversion on a '57 Johnson 35. Took all of an hour, with painting to match.

Yep, I found a tiller on ebay for mine. Direct bolt and go. Easy as pie. I glanced through ebay earlier today looking for a tiller for it, as I am thinking about changing the short shaft one to tiller before I sell it. Didn't get past the second page, and didn't click on them, but I think I saw one that fits it. May want to check it out, and then rethink it.
