More seriously - I presume that your Aux can't be mounted on the Port side? If it could, a wee length of PVC wastepipe could be employed as a tiller extension and you could steer from the rear jockey (maybe?) When not in use they make a great rod/boathook holder if clipped to the A-frame.


The little 'un doesnt have a long enough shaft .. despite the height looking ok on dry land.. because its working off set so much, if its anywhere close to the base of the hull I've found cavitation to be a significant issue.. so weight needs to be pretty much aft anyway to keep the blades gripping .. these small motors are tourqey but the blades need fully buried to work effectively unlike some bigger engines, and the cavitation is enough to make you lose 40% or so of your forward speed, and that has a big effect if it happens every 30 seconds or so, particulary when you are only doing 5 knots

This is where a bracket is quite handy, as lots of them can be raised or lowered and it opens up the range of small engines you can use on your hull. IIRC many are rated to 20 HP or so, but TBH Ive found their mounts flimsy to say the least and I wouldnt hang more than a 10 on them.

Its not such a big issue for the south coasters ofcourse.. but up here in the North Minch .. theres a lot less traffic to help you out if you get in trouble,.. coupled with the way the sea can change so quickly here and as Spartacus said, if you get a prevailing southerly ..say tata to a hot dinner for a long time ..
