What size auxiliary?

As above what are ur using on your 6m RIBs?

In the market for one of these, thinking 8hp.. Would 15 be too big?

often the problem is what size physically fits.

assuming you have plenty of room then a 9.9 would be pukka, or if you can manage the 15hp in terms of transom weight/fitment then, why not!

8hp upwards would be good though if you have room.

cheers

Got a 4hp suzuki on mine couldn't go any bigger on width fixed on the transom not on bracket gives me 3.5knots 6m x 2.4m beam use main engine to steer I find my double 60mm A frame a pain to use the aux on the bracket so fixed to transom.
Reason for 4hp bought it for small sib best of both worlds

15 is pointless. You'll never plane with an auxiliary, so all you need is enough to reach the displacement hull speed.

8hp is enough for my 7.8m, so will be plenty on a 6m.

Agree with Nos you'll just create froth and get nowhere fast. I have a 4hp fourstroke on mine and has proved itself. So your eight will be okay

15 is great when your having to toy another 7m into deeper water

Are you sure there wasn't a slightly sarky undertone to it?

To be fair, I think my 8hp would probably do it too-all it does is make foam on the top 1/3 of the throttle.
