Thanks Stephen Thats interesting

Can you steer it at all with any sea running or is that a lost cause

where we are a F5 sea breeze with a chop is the norm. coming into a narow harbour enternace could be interesting.

To be honest I haven't tried with any kind of a sea running - but I think it would be difficult. To offset any tendency to turn with the sea I would think the best answer would be to offset the tiller on the aux a bit more so it is tending to turn you back in to the sea, until your main engine is about in the straight ahead position for steering. Just my theory though - I haven't tried that! However I think it would work as the reason I run with my aux thrusting slightly to port is because I discovered I had lots of steering in one direction and bugger all in the other so I adjusted it till the boat was running more or less straight and I had reasonable steering in both directions.

The other reason I prefer to use the main engine as a rudder is that my boat is an awful lot wetter sitting on the tube at the blunt end than where I normally sit

Oh yes about 90 hours steaming on a single aux engine across the North Atlantic to get home

I have mine mounted on a cut down and narrowed outboard bracket about 6 inches behind the transom. It means it clears the A Frame.
I used to have a small 2 stroke 3.5 and despite buying it new a year later it was gubbed. I didn't run it much because flushing it was a problem and fuel had to be premixed which was a problem for storage. It was found the first time it needed to be used for real that it was knackered!
I have since bought a 2.3hp 4 stroke Honda which is air cooled. Fuel is now no problem and I run it every trip cos it doesn't need flushing.
It seems to steer OK using the main leg apart from the above mentioned large turning circle. I haven't tried it in rough weather yet but it doesn't need to be perfect, just get me home......

If you have a aux fitted, make sure your mate dosen't drop it the sea when he takes the boat out?

on a more serious note

has anybody changed their prop on the Aux.
I was just thinking about it. If I have a 6hp aux it will never get on the plane so there must be huge slipage or the engine will never reach optimum revs.
I also have an 8hp short shaft on an Avon 2.8 rib which we used as a tender and that gets up on the plane with 2 or enen 3 up.
What props do these sailing boats have on their auxilary outboards? they dont plane.

Very valid point - often they have high thrust 4 blade props - bigger diameter for more thrust at lower speeds. Having said that some of the outboards are also available with different gear ratios as well but they don't all offer that.
