The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
no oversized bearings avalible from yamaha, dunno about someplace like jasper.
if a 4 stroke yamaha crank is damaged you either send it out for a journal rebuild or replace it.
the color codes simply adjust the oil clearence for a standard undamaged crank and main saddle.
