My understanding when shared .... was the engine was rolling opposite direction of the LH Rotation of the propeller for a neutral point.
I don't mean to be argumentative, and if anybody wants to correct me, please do, but.... I don't think the rotation of the engine imparts any torque upon the boat except through the prop against the water... I guess I could see, MAYBE, SOME counter-torque during acceleration, but not while running. I'm genuinely curious if anybody has any data to support this theory. Thanks. Brad. (937)545-8991 |

(937)545-8991 I will say Check300's boat ran extremely well for Silly Power Single Engine Boat |

I will say Check300's boat ran extremely well for Silly Power Single Engine Boat Oh, I'm not doubting that. I know Kunkel's 300 CM ran 110-120 with a monster blower motor of some sort. I'm just curious about the counter-torque effect of running the prop LH. The physics don't seem to hold up. Thanks. Brad. (937)545-8991 |

Prop was a Dennis Cavanaugh Special, Bret @ BBlades knows the particulars

Cougarman,
What a sweet set-up. That is awesome. Thanks. Brad. (937)545-8991 Brains / Tom Earhart Also the very First #6 Extension Box (Also Tom Earhart) Transmission is in the box. Napkin Sketch for BAM Marine, which Contracted Stelling's to build it for Tom & Bill. Now you know the rest of the story... on how Stelling's Extension back came to be... |
