I have had small backup outboards on 20-foot ish boats and found the following:
1. You will travel very slowly indeed with 3.3hp, possibly in the same direction as wind/current, rahter than where you really want to go
2. You therefore need to run it full throttle if main motor breaks down. At this speed they vibrate like hell, so make sure the bracket is solid and firm. Or very rubbery. But not full of loose links and hinges and pantographs.
3. Try to fit it near the centreline, but you have to compromise a bit becos it gets in the way. If offset, then starboard is better than port for a r/h prop (though you might choose to put it where it doesn't get in the way on your berth, etc)
4. Mount it low, so the prop is pretty deep in the water. Otherwise, in a big swell, and bearing in mind you will be bobbing along at 3 knots (if you're lucky) the prop will come out of the water as you ride the waves, becuase it's so far back on the boat
5. On the other hand, you need to mount it high enough that the whole thing is clear of water when tilted up and going fast on the main engine., Else it drags and splashes.
Seriously, I wouldn't rely on it too much. Effort is much better spent keeping the main engine in tip top condition, not relying on a food blender masquerading as auxilliary engine
Oi!! have you lot not heard of relaxed muscle /forums/images/icons/laugh.gif At least i may have found a club where i am not the biggest /forums/images/icons/wink.gif We can't all be combat fit like SWMBO thinks BarryH is at our age /forums/images/icons/laugh.gif Mind you I think BarryH has had liposuction, because he drinks like a fish /forums/images/icons/laugh.gif I ordered some size 10FB chest waders, I did wander what the FB was for, but was relieved when they told me Full Body /forums/images/icons/laugh.gif

Thanks for your kind advice, I have told SWMBO what you all have suggested, she thinks it is a good idea so as not to lose the engine, I have ordered a 200hp for her first trip, you know get her to the beach quicker /forums/images/icons/wink.gif She is quite happy to put the wrist strap on /forums/images/icons/laugh.gif let's hope we don't drop it /forums/images/icons/wink.gif
By the way the outboard bracket is to go on the boat to make it go. I have been concerned about the hp so have made an enquiry about a Honda 8hp long shaft but it is about £1,600 /forums/images/icons/shocked.gif So I need to know if I really need it. I am seriously running out of space so would need to keep it on the bracket all the time, unless I go for the 'A Frame' I have been considering. I fix waterproof storage containers on it like a rib, that would free up some space. I do think 2 back up engines is a bit mad, but better safe than sorry.

jeez Happy - just go boating and enjoy it. If you are worried about getting back with an engine failure just keep buying Barry and I beer (Geoff too) and we will stay and look after you at the pub until you want to go home..........400 a year max budget I would have thought but watch out; some unscrupulous people will have you believeing you need 10 boats and crew just in case - and your bar bills will rival Eddie Jordans servicing costs!!!!
