Hi Derek,

I use a Tohatsu 5 HP two-stroke long-shaft engine as an emergency engine on my Hardy 20 Family Pilot. It creates a speed of 6 knots with the water flow and 2 knots against the water flow on the Elbe river near Dresden in Germany. This flow speed of the Elbe is around 2 - 3 knots.

I use a stable "lift" from Allpa as a holder. This can carry 50 kg.

Greetings from Germany!

Hi Derek There is quite a lot of messaging on aux. outboards and brackets. See engines 13th april.

It is difficult to get an outboard at the right depth and then lift it high enough to tilt into horizontal mode. Ideally when running the cavitation plate should be no higher than the bottom of the hull so the prop is at the right depth. This may make the OB tiller more vertical than horizontal but still ok to steer. It is also possible to crudely steer with the main engine. With the prop set at the right depth raising the OB may not allow you to lift it into a fully horizontal position. Most new outboards have a shallow water option which may allow the OB to be clear of the water when raised. It really is about compromise. For non tidal waters I would suggest a minimum of 4hp long shaft with an option for an external fuel tank. For tidal waters 5 to 6hp. 4 strokes can be quite heavy so go for the most substantial OB bracket with at least two springs. All the OB brackets claim unrealistic maximum engine hp and weights. I suggest the hull should be reinforced to take the bracket.My own OB is a 6hp mercury and it weighs 27kgs. An elderly 2 stroke might be a cheaper and lighter option but only really on non tidal waters. Hope this helps. keith
