Weirdest DIY outboard you've seen?

I'm considering rigging up two moped motors as outboards on an as yet unpurchased 22-24 foot boat. Has anyone ever seen anything like this done? Its crazy, but it'd be more for the novelty than anything else. I certainly wouldn't count on them as a primary way to motor.

I'd call the boat Minnow-relli, if there's any moped/scooter folks out there to get the joke.

Re: Weirdest DIY outboard you've seen?

Hmmm....Nope. Can't say that I have seen anything like that. I've seen an old Seagull outboard on a Dragon. That's about it. Usually you see the weird franken-engines they are on the back of a 12' "tinny" or something. Are you sure you're not a closet powerboater?

Moped engines are air cooled, how much airflow do they need when they are working flat out? How much power do the Minarellis put out? You need 2 of them?

You have many challenges ahead my friend!

Why not go the whole hog and convert it to a paddle-driven setup?

Outboard

There are many of our southern americans(with engineering like that I find it hsrd to believe they lost the civil war) that have put a push lawn mower engine on a outboard lower half. The videos are one the net. Must see make popcorn first.
The have used chainsaw engines on gocarts.

Re: Weirdest DIY outboard you've seen?

I remember seeing a lovely setup on a Sakonnet daysailor. They used a trolling motor that sat in the socket of the sheet winch so that it could be easily removed once you were away from the dock. Maybe you do something like that with your idea?

Back home on Lake Ontario after something over 36,000 nm circumnavigator. Not surprisingly there is a lot of stuff I want to get done on Ainia both cosmetically and functionally. Getting an early start so it will be ready to go for next summer (Lake Superior?).

Go all in; put a Harley-Davidson engine on board. It would increase the value of your boat 2x. Put the harley sticker in the window and the price would jump again.

Re: Weirdest DIY outboard you've seen?

I've seen plans for an outboard using a lawn trimmer engine and shaft. Essentially pull the line head and replace with a prop, then add a mounting racket . . . Umm . . . I mean bracket. On our dinghy I use an electric trolling motor because it's so quiet . . .cheap too.

Then get you some black & orange life vests with a skull on 'em, and name her "Miss Screaming Eagle" and value goes up to 3X!

Re: Weirdest DIY outboard you've seen?

What I'm waiting to see is someone adapt a jet ski motor and drive on a sailboat. It would keep the transom clean.

Haha, I don't see a weedwhacker doing the job. Dandelions don't take much torque to cut, doubt it could handle it as soon as the prop hit the water. But try it!

As for cooling, depending on the cylinder and head, they can go from 2hp a piece up to 6 or 7, and be air cooled (with the help of a fan) or water cooled if you're crazy and awesome.

And I don't think putting two tiny motors on a boat makes me a powerboater, does it? Maybe an underpoweredboater haha
