You would be suprised at how little space you need to fit an AUX.
see the picture below of my installation..
Things to bear in mind....
- When tilted forwards you have more space for the main engine to turn (I can turn mine on full lock with no chance of touching)
- With the AUX you dont really need it to be able to turn to full lock as you will find the easiest option is set the AUX straight and lock it in that position then use the main engine to steer.
- I do have to be a little careful when my main engine is down as well as the AUX as they will touch when I am steering sharp left.
- If you need to manouver in a tight space that is when you might use the AUX to steer, again you will be suprised at how much steerage you get even with a reduced lock.
- If you can, fit the AUX directly to the transom and not to a bracket as this makes the whole installation easier to use and less likely to break in heavy conditions. This will probaly mean you need to source a long shaft version of the motor. I tried a standard shaft on mine and it cavitated every time the boat went over even mild swell.
- the easy way to set the Aux up is hang it on the transom as far from the main engine as you can then test to see how it all goes together if you can afford to move the aux closer to the main engine to allow for more steerage on the AUX then go ahead.
