Maybe but I think running a boat is too much for a small air cooled motor at full throttle on a hot day. Most air cooled power equipment never runs at full throttle like a boat motor does. Anyway it was only 3hp or so-way to small for the boat.

I did then what I knew how to do ~ now that I know better I do better

We tried it out today and the little 3.5 hp scooted my little boat right along!

..I also have a 427 Cobra replica with an aluminum chassis.

Evenrude and Johnson were part of the OMC group. It was totally unexpected when I first found out they had stopped production.

A neighbor asked me to have a look at one of the last 25hp engines they produced. It was so high tech with fuel injection and so many things. I told him there was provision to plug a scanner into the system. I also told him there really was nothing I could do for him. Without a service manual especially. A really bad ideal to use that motor in salt water. The salty atmosphere would probably get the electronics.

Perhaps even more complex than a car engine as to electronics. It was good on fuel quiet and powerful. The cost to repair the electrical issue was very expensive at a service place that had sold them new.

To this day I do not know why they stopped production. They had brand loyalty and outboards where becoming expensive new by then. Where these older ones like I have tend to just have things like coil failures because of age. Compression seems to remain really good on the majority of them as well. OMC also sold a lot of lawn boy two stroke lawn mowers over the years. They were produced in a small Ontario, Canada town.

You're right about the durability of the old ones ~ forty + years ago my then partner called me from up North and said "I dropped the outboard motor off my boat, it's still there, no recovery diver until to - morrow, what do I do next ?" .

'simple ~ go RIGHT NOW and buy a BIG trash can with lid and have it filled with water and ready when the diver brings the motor up, drop it into the can filled with fresh water, rope the lid down tight and bring it to the shop when you finish your vacation , no hurry, NO NOT ALLOW IT TO BE UN SUBMERGED ! ' .

It took me about 30 minutes to drain and clean it, get it running in the shop in a steel drum of water, he was still using it 25 years later, no damage .

When I was a kid in the 1960's I watched my dimwit middle brother fooling 'round in the Finger Lakes with a small Johnson outboard, slipping it from forward to reverse at sped, in time it backed itself right underwater.....

Pops was furious and told him to take it off the boat and hang to dry, of course it was ruined .

Some times children really *do* know more than the 'adult' .

Pops was all wrapped up in being a world famous Oncologist and never listened to anything his children tried to teach him until the 1990's .

When you live on a farm you learn to save and salvage things that most just toss out because they don't really know what makes things tick .
