what does it take to bend a prop shaft?
i just got a new parts motor and the guy i bought it from said it was locked up when he got it (motor).
now i have all the pieces and the prop doesnt look that bad heres a few pics
i have pointed out the worst spots on the prop............but they seem insignificant as far as prop bending hits........am i wrong?
i cant find my dialindicator and the tool truck i like wont be in town for a couple of days wo heres what i did:
i took my micrometer and put one end against the trim tab area then i put the other end in the hole at the end of the prop shaft. with the lu in a vise i had my son turn the drive shaft (while in gear of course) and i kept rubbing the adjustment wheel on the mic to make sure it stayed against the one side of the hole.......................it appears to have moved .04063" in one revolution.
is this within specs?..........is my test accurate enough?.........should i just suck it up and wait to buy a new dialindicator?
