I have looked at alternatives to gas and found that the energy density and/or speed of refuel just wasn't there. For me the biggest advantage to a small OB is that it can be easily loaded and unloaded with no separate gas tank. Bigger ones are significantly more trouble to load/unload. The small ones have integrated fuel tanks and typically run for about and hour at full load. Once back at the boat refuelling is quick for either big or small but an electric can take 15hrs. Where is it getting it's charging power from and how many Ahrs?
For me electric is out of the question. Propane? How do you tell how much tank you have left? Are you stuck carrying multiple 1lb tanks? One gallon of pre-mixed fuel should last at least 4 hours of operation (~4 tank refills) in a 2-3 hp 2-stroke. If you mix it with a synthetic 2 stroke oil like Amsoil you can mix it at 100:1 and have almost no smoke. It's easier and faster than rowing but not exactly on plain.

They are a spendy. *From:* CnC-List [mailto:cnc-list-boun...@cnc-list.com] *On Behalf Of *Della Barba, Joe via CnC-List *Sent:* Monday, October 26, 2015 1:43 PM *To:* 'cnc-list@cnc-list.com' *Cc:* Della Barba, Joe *Subject:* Re: Stus-List outboard size IMHO there are two ways to go with an outboard: Go big or go tiny. I have a 15 HP 2 stroke Evinrude I really like. We can do 18-20 knots with 3-4 people in the dinghy and we can two a tube with a kid or two at planning speeds. If I were to have a dinghy that needed the engine removed to tow or put away, I would get the lightest engine I could find. You can scavenge Craigslist and sooner or later find a 2-3 HP two stroke that might weight 20-30 pounds. If you can’t plane anyway, no use wasting gas and engine weight with being close to planning vs. really not planning. I had a 2.5 HP Honda years ago that did fine for getting around at low speeds.

Same weight – or less – and vastly more speed with a load or in rough weather.

Moves along quite nicely, but vibrates. The J-24 has a Tohatsu 3 hp two stroke and also moves along nicely. I would think anything 2 hp or more would move your inflatable well, just don't expect to plane.

During dinner the wind came up. Our boat owner friend towed us back to our boat with his dinghy with 2.5 hp Tohatsu. It was a little bit of a struggle but the little Tohatsu did the job. I have a used 80's Evinrude 7.5 that will plane my 9'4" dinghy. However, if I was buying a new one, I'd definitely go much smaller. I think a 2.2-2.5 hp would be fine. The last 3-4 years I haven't even put the OB on the dink, preferring instead to row and avoid the hassle of installing/removing the heavy OB. Dennis C.

I have recently bought an 8ft inflatable as tender and am looking at second hand outboard options. Can you advise me of adequate size required? Specifically I have seen a 2,2 hp advertised. Will that be enough to potter to the dock and back? The safety sticker on the boat says up to 5hp but that seeems a bit much and heavy.
