Small air oiled OB engine? I'd rather row.

The only acceptable dink engine IMO is an OMC 3hp twin cylinder OB. Quite old now. Had too many mechanical issues w the little twin (mostly water pump) so I bought a 3.5hp 4 stroke. Too much vibration. Too heavy. And I hate avoiding setting it down wrong so the oil runs out.

Now I suppose I may consider the smallest propane OB.

First I have to say I'm a Lehr dealer. That said, I bought a Lehr 2.5 a couple of years ago to replace a Suzuki 2hp. I got tired of rebuilding the Carb every time I wanted to use it. I like the 2.5 so much I recently bought a Lehr 15.

I also sometimes use an Electric trolling motor to push my dinghy and a canoe. I use two small batteries. Don't know the size but they are smaller than group 24. When the first battery dies, I hook up the second battery and head for home.

For a small dink, I reckon you can't go past the wee Honda 2-2.3hp 4 stroke. No-one has mentioned the best feature of being air cooled is NO NEED TO FLUSH THE THING AFTER USE, and…you can do a quick start while still mounted on the bracket before putting on the dink, so you can know it will go 1st pull. Which function is almost guaranteed anyway, (unless the gas is way too old), because of not having oil in the fuel (Eric), so no plug fouling, and being so light, it's a snip to put on and off, so what's not to like..?

Generic thoughts. Choice of dinghy and propulsion is largely dependent on:
- how would you use it (pax, distances, etc.)
- how would you carry (or stow, or tow) it
- how would you handle the weight (of each, dinghy and motor, if separated)
- how would will feed it
- etc.

I'd say each of those propulsion choices has pros/cons, dependent on answers to questions like that.

Sometimes answers to one question will help answer another. For example, 4 pax and long distances suggests a larger/heavier dinghy, which in turn suggests more horsepower. If you can carry the weight, or two the dink, etc.

And so forth.

I think on the spec sheet I agree, its just I can hear them coming and going for miles, that noise would drive me crazy, but everyone makes their choice.

if you're not in a hurry (most trawlers are not..) that's one neat way to go!

We have a 3.3hp 2-stroke (Merc branded). Do not like the mixed oil/gas feel on my hands, but do like the very light 29lbs weight. It works just fine and will tell you is a LOT quieter then the little Honda's! (Really, take a listen some time - not sure what is up, but Honda missed the mark on that one I think)

And do take note that these days most all small outboard motors (15hp and less) are re-branded Tohatsu’s - Honda being the exception. This has been true for some time now.

If I had a proper hard rowing dinghy would go oars in a heartbeat. But these darn RIBs row about as well as a garbage scow IMHO – so small outboard it is. If the Honda’s were less noisy, would look hard at one of them - even if they are 2-3lbs heavier.

thomasonw,
Is this a variation of the 4hp single cyl Merc? That would probably be over 40lbs.
Or is it a Tohatsu, Nissan or other brand engine.
In other words who made it?

It is the little brother of the 4hp 2-stroke. Tohatsu 'made' it, it is branded Mercery. The SAME engine was sold under the Nissan brand, as well as Johnson and others. Stickers (and at times the plastic cowling) is what differs.

It was also available as a 2.5hp version as well, with the HP difference being a metal stop that prevented the throttle being opened all the way. (I suspect there is a like relationship between the old 2-stroke 4hp and 5hp models as well - but have not confirmed it)


The little lightweight engine I am talking about is 13Kg (or 28.6lbs) - no longer sold new in the USA:
Mercury | All Models 3.3hp

Here is the spec for the 4hp 2-stroke (20Kg, 44lbs) one:

I've got the little 2.5 hp 2 stroke Merc. Simple, lightweight & dependable.
The only thing I wish it had was a neutral gear. You have to be ready to go when you start it up.

Suzuki makes all their own small engines, and I think Yamaha does, too.


Suzuki made some engines for Johnson, at one time. We have a Johnson 5-hp 2-stroke, made by Suzuki, late '90s.

I have a little 2.5 zuke and it's great. Pretty quiet and has neutral.

Someone mentioned short range on the propane fueled Lehr. According to their web site, it runs for 48 hrs @ 3000 rpm on a 20b tank of propane. I've been considering it because it seems safer than having gasoline on deck. Here is the link:

You know Chris, I think you are correct - perhaps more accurate would be "..most all US small outboard motors.." + Nissan

Maybe. Last I heard, Mercury is pretty much the only "US" brand of small outboards? Johnson is toast, Evinrude (last I heard) isn't making anything under maybe about 40-hp? Anybody I'm forgetting?

When I was shopping for our new 15-hp outboard, I found Honda, Yamaha, Suzuki, Tohatsu, Nissan (Tohatsu), and Mercury (Tohatsu).

And I think I've read recently that Nissan isn't going to be doing small outboard anymore (even if they were by Tohatsu)?

Me too. I'm in no rush, but when we are full time cruising, I want to leave a 2 HP Lehr on the dinghy for the loop and keep the Merc 9.9 2 stroke for the islands. I never asked if the Lehr had a neutral, but it's a good question.

The Lehr 2.5 has neutral and forward. Spin the engine around for reverse.

My 5hp Tohatsu 2 stroke is a simple reliable little beast of burden. It can get the dinghy on the plane, but in hindsight I`d be better off one model smaller and lighter, the weight is at the edge of what I can manage fitting/removing it from the 2.7M inflatable in the water.
