Good info all....Weight to horsepower seems to increase between 5&6 hp and then seems to level out.
Mercury weights (from Defender site) 2.5hp is 28lbs, 3.3hp 29lb, 5hp is 45lbs, 6hp 73lb!, 8hp 73lb, and 15hp 77 lb.

SD-What I saw said your 3.5 Tohatsu is 41lb. That's manageable...Its that jump into the 70's that hurts.

Twenty years from now you will be more disappointed by the things y%^&*.....oh never mind. 90% of the people on sailing forums already use that as their signature! I'm not a conformist.

And built in gas tank is another big thing. If you are motoring 200 feet who wants to set up and prime a gas tank.

A couple nice features to look for: Throttle control on tiller, and neutral gear.
The Mercury 6 has an alternator, probably explains the jump in weight from the 5.

They make lightweigth 4-strokes, but I cannot remember the weight. Also, as was mentioned earlier, the throttle placement and gear placement is a big deal. I am not sure if your tender can plane, but if so, the extra HP could be worth it.

British seagull or small Evinrude or even a 'cruise n carry' (Shindaiwa) will work. The secret to keep these small engines running is to run the carburator fully dry **each** time you shut down .... never ever let gasoline 'sit' in the carb for more than a few hours. When storing for long term remove ALL the gasoline mix, open the main jet and squirt in a little isopropyl alcohol.
Other than that both the water cooled Seagull and the Evinrude dumps the cooling water down the mainshaft ... which requires that you disassemble the powerhead from the shaft every 6 months or so to regrease the splines in the crankshaft nose ... if you do this and the above the will last 'forever'.

All the 'small' outboards require clean and FRESH (less than a month old) gasoline ... do that any will have 'nary a problem. Never ever let gasiline sit in a small outboard for more than a month and ALWAYS run the carb dry every time you shut down.

Honda 2HP

I have come to really like our HP (26.7 lbs) Honda 4 stroke. It has an internal tank and throttle on the tiller. It takes a bit to get used to operation, no reverse (the engine turns 360+ degrees) or that the prop engages when you increase the throttle. Heres a link to it...

Honda BF 4-Stroke Marine Outboard Engine - 2 HP Motor Specs


The motor came with the dingy when we purchased it, initially I wanted to increase to a 8-9 hp, but I have got used to going slow and joy the ease of putting it on the dingy with one hand behind my back

Anyone had luck with these electric motors?

There are many things the British do that are admirable. Making engines is not one of them.

Seagulls are in fact held in high regard by corduroy trouser wearing anoraks (with elbow patches) who actually know what is meant by sheerstrake, oakum and pitch and who even know their intended use. Brave souls who take cold baths in the winter , wear woollen underpants, swear by a gaff rig and consider everything that has happened post Disraeli to be a retrograde step with the possible exception of Margaret Thatcher.

If your concept of cutting edge technology is a 1948 Morris Minor then Seagull is your kind of motor.

I like it, and it will run about an hour on the 1/3 gallon in the built in tank. I wish it had an option for an external tank, but it doesn't. I believe that the small Mercuries are actually made by Tohatsu at the moment.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Sd,
How old is your engine ? We were looking at a small 2 stroke outboard earlier this year and I'm sure (but cannot quote you model numbers) that we looked at botha tohatsu and a mercury both of which had built in tanks but could also take an external.

Brand new... just got it... believe it is a 2007 model. However, it is a four-stroke... that may be why it doesn't have an option for an external tank, since four-strokes are considerably more fuel efficient than two-stroke engines are.
