| I realize it is a sterndrive, but thanks for pointing out the obvious. Actually, I have one on the back of my boat, so I know quite a lot about these units. I wasn't necessarily responding to you, I was responding to the ealier posts that asked if there were any counter rotating surface drives.  |

| I've installed on the same boat the single and the duoprop of Volvo Penta. At the same displacement and power the gains in speed have been: single duoprop --------------------- 25.0 > 27.5 knots 30.0 > 32.4 " 35.0 > 37.6 " In effect 2.5 knots more. Better acceleration too. RANCHI OTTO |
