Just because it says "20" on the cowl doesn't mean you have to use it. You can still only use 10-15 hp if that's all you want. BUT....if it says "15" on the cowl, that's all you'll ever get. If you can "afford" it in cost and weight, get the larger motor. There's no downside. You might find you want to tow a tube, run into a strong wind and current with an extra load, need to help recover the anchor from the mothership......the possible needs for extra HP are infinite...the possible problems are 2. Money and Pounds.

If you're not careful, 'Torque Steering' (for lac of a better term) might also be an issue with a relatively "high-powered" tiller-driven outboard mounted on a relatively short and light boat. I lost a brand-new 9.9 Penta that way. It now rests in peace at the bottom of lake Morisco, which as we all know, is deeper than Hell.

On the lake, some bass boaters would switch engine cowls. Suddenly you'd see a bass boat outrunning bigger hp boats and no one know that it had far more hp than indicated. You could get a 20 and get a 15 cowl and then look like the fastest 15 ever.

Great! First, we had the Hemi-powered Prius, now we've got the Sleeper Dink.

Granted, this was back in the mid-80s, but my soft bottom 3.10 Zodiac stood practically straight up when I slapped the 9.9 Penta on it.
Since I was in a hurry to try out both the new boat and its new motor, and obviously couldn't sit in the back, I had a redneck brain fart.
I duct-taped the extensions that happened to be laying around on my wife's favorite vacuum cleaner onto the tiller and sat with my feet dangling over the bow.
I'd already made it around the lake a couple of times at moderate speed when I decided to see if I could actually get the boat to plane, so I opened the throttle, and it was at that precise moment that I learned that duct tape doesn't hold up all that well when wet.
I was almost on a plane and at WOT when the vacuum cleaner tubes detached themselves from the tiller, the motor swung violently, and the Zodiac did an Olympic-quality double salto.
Unfortunately, it didn't land on its feet like most Olympians do, and I lost the motor to the bottomless pit which is Lake Morisco (a.k.a., 'le lac de la Négresse').
The worst part is that the vacuum cleaner tubes followed right behind, and that my first ex-wife still brings it up at every alimony hearing.

That's hilarious, Jacques...!!! Literally laughing out loud...

That being said, that great story as a basis for why not to go with a 15 or 20 on a dink makes less sense than duct-taping vacuum cleaner tubes to a tiller handle to pilot a dink from the bow...

Got it. OMC Light twin.
One of my favorite motors. 4 hp Two cylinders. 32#. Smooth and starts on first pull every time.

I had one. Pain in the a$$ to start, not easy to maneuver given no reverse or neutral, mostly caused bumper boats in tight quarters...

I really like having reverse on a dink motor. Had two without and it annoyed me more than I expected. Present 4hp has reverse and I like it.

I agree, Ski. Reverse is important.

The Honda 2 has an ingenious swing/flip-tiller feature that makes using the reverse a breeze...if you sitting on the stbd side. Apparently it's intended to be completed with the left hand. It's the only way I could get it to work properly. I watched a newbie struggle with that motor from the port tube. When I suggested he switch sides, he was a natural.

Having a centrifugal clutch was a nice feature on that motor, too. If you were in low idle, the prop was stopped. Goose it a bit and the prop turns.
