All outdrive motors turn the same way. As you suspected, the drives turn the props the other direction.
Jeff
PS: Most new inboards are set up similarly, with the marine tranny reversing the shaft rotation internally. |

outdrive engines are left hand rotation.(counter clockwise from flywheel end) regardless of prop rotation. |

Now you're going to Confuse Everybody,............
It's only Us Mechanics that Ever look at That End of a motor..............
John is thoroughly convinced he has Clockwise, Righthanded motors..........
Jeff answered his question,..... Correctly Btw,....
And never told him that he has it Backwards.............:D
Btw,..... John,...... Loose the Cap-Lock,......
It's considered YELLING,+ Rude in most forums,............. |

me again. in truth, the reason I wrote that is John was talking about rebuild. would hate to see him think he was working on right handed engines. could cause a lot of problems. |

Help- I allowed my mercruiser 5.0 L gas engine ser.#0F429852 MCM#450B100HS to freeze last winter. I am wondering if I can use the following for an exchange - OMC modl# 502STHRCRA,
ser.#J808164 I am quite sure both are GM 305's. If they are interchangable what major problems might I face? Thanks, dean |

I have a 1971, 318 In my century resorter, I did not winterize it corrently for the first time in years, and have a crack in the crank shaft vally. I am planning on replacing the engine, I bought a standared rotation engine and relized I need reverse, can I run my Borg-warner velvet drive on a standard rotation engine? thanks Pat. |

the gear can be made to rotate either way.(by rotating the pump)lots of acc's to consider also.alternator,sea water pump,circ. pump, etc. the boat handling will be different as well. some boats (penn yan for instance) handle like a brick with a left hand engine. give it a lot of thought. |
