Re: honda prop nut BF15A
Manual for my '06 BF20 (basically the same lower unit as yours) says the following:
- 'apply marine grease on the splines (drive shaft)'
- 'torque prop nut to .7 ft/lb' (yes, that is .7 ft/lb - not a typo)
- 'if cotter pin cannot be installed, tighten the nut additionally until the cotter pin hole is accessible. Do not exceed the max torque of 25 ft/lb.'
When I put on my prop, I just snug the nut very, very, lightly (few ft/lbs).
Manual recomends use of a SS cotter pin. May be able to find one of these at a good local hardware store.
