Welcome to Ribnet doc,

Short shaft; Chinese fella,
Standard shaft; English fella,
Long shaft; Welsh fella,

ps Best go with what manufacturer recommends I'd say.

Did I read that correctly? An 11.5 Meter Zodiac? Surely you mean Feet? Do what the Manufacturer (Zodiac?) recommend - they probably have the hang of these things by now....

Hi Doc

I would check what zodiac say and then if you can give a few more details we can help i.e. budget, is fuel econemy important, do you need an aux engine as a back up (i.e. are you going out on the sea) short or long shaft etc.

happy boating

Dave

What you gota think about Doc, Is how fast do you wanna go, If your just looking to potter around the harbour with no interest in speed then 5hp would be fine with maybe 2hp as backup, Or if you gotta need for speed well, Check what max engine size with dealer,
As for shaft length, As mentioned do you intend taking to sea, If so in totally calm conditions a short shaft would be fine, If however you expect to encounter slightly choppier water on a regular basis, Then a longer shaft would be better, Reason being your prop will lose propulsion momentarily as you pass over the crest of some waves, Especially in a following sea, Travelling with the waves,
Also transom height and hull depth, Would determine the correct shaft length on all outboard style transoms, Sounds like you would probably be better off with a short shaft i'd say 10hp should be enough to get you up on the plane.
All the best with choosing,
