confusion concerning multi-outboard engines...
OK, I'm familiar with twins, and their oposite rotating props for
steering. But I've seen craft with three and even 5 outboards.for simplicity sake if looking fromt he stern, the starboard engine
props to the right, and the port engine counter-rotates tot he left,
then which way is th center engine (or engines) just curious. Tim |

| On the other hand, if you lost the left handed engine, you'd be
running on two righties. Any ill effects? |

| other than a slight over steer because of torque, no. i only have twins on the contender, but ive driven triples before. im
not sure, but the center prop may have a different pitch than the
other two - seem like I remember somebody telling me that. |

| ok, now i have a question. first, a friend re-powered his 18-ft center
console boat with 'a deal' on a yamaha 150, counter-rotating engine.
appraently, as i wass told, someone else had ordered the twins for
something, then never picked then up. oh well, not my boat, not my problem. what i have noticed now is that his boat is way "squirrely" at ilde and
slow speeds. my guess is maybe something is built into the boat design
to account for a normal right turning prop, and now with a single left
turning one, the boat attitude is a bit out of whack. it is also a bigger engine (150 vs. 115) from what was there originally
and i think that may have something to do with the new attitude. the
boat is rated for a 150 max, so i would say he is not over-powered. |

| Clockwise, correct. > and the port engine counter-rotates tot he left, Counter-clockwise, yup. > then which way is th center engine (or engines) From what I've seen, with an odd number of single-propped motors, there
is usually one more right-hand than left-hand. At least with outdrives, chances are good nowadays that all will be
duoprops, thus negating the problem. :) |

| usually right hand, but they can be left hand. |
