| Post subject: | Longtail Build Questions |
Just picked up a 7hp Honda clone for my build. Im putting this longtail on a layout boat I built which is 10' long and weights 95lbs. Im thinking about using a 60" drive shaft. With such a small motor, what size DOM tubing should I buy for my shaft housing? 1-1/4 OD x .188 wall x .874 ID, 1-3/8 x .250 wall x .875 ID, 1-1/2 OD x .250 wall x 1.00 ID? Also, not sure if I should go with a 6.5 X 4 prop or a 7 X 4 prop from Hill Marine. any thoughts/suggestions? Thanks |

I use 1 1/4" OD 1" ID. DOM tubing. I think you might be getting a little too heavy with the others you mentioned especially on the short boat you mentioned. I use 7 x 5 props. |

Is the ID for you shaft housing truly 1"? I can't seam to find anything even close. Where do you buy your DOM from? Would you suggest a 7 x 5 for my application? |

Yes it is pretty close never measured it specifically. I thread the OD and turn bearing housings for the ends. I get it from my steel supplier. I am in a family owned a machine/ fab shop. |
