Cotter Pins
by Steve from Algonquin, Illinois on June 15, 2014
I ordered cotter pins with my new prop and hub kit and when I unpacked my package, I totally forgot about the cotter pins and recycled the box, cotter pins and paper insulation in all. In the future, I would suggest that you tape smaller parts to larger boxes so dummies like me won't toss them out.

Q:
What prop nut kit using solar hr titan 4 prop on a 2015 yamaha f300?
A:
You will need part number 18-3782.


Q:
I have a 1996 Yamaha T50TLRU 50 hp outboard. How do I determine which oil/grease seals are needed for the vertical shafts in the lower unit? I already bought the prop shaft bushings from you?
A:
The only oil seal we have for the drive shaft is this: http://www.iboats.com/Oil-Seal-Sierra/dm/view_id.171775 You will have to contact Yamaha for the shims and such.
