Cutless bearing size issue...

N.Z here. Bought a new one inch shaft. What do you know it is not one inch!Close,( forget the difference now), but apparently that is the way it goes. Only noticed when fitting the cutless brg.
 
Shafts are made either 1" or 25mm - a0.4mm difference. a 1" will not run with a 25mm cutless and a 25mm will be sloppy in a 1" cutless and will wear quickly. bearings are made specifically to fit the size of shaft and should not be mixed. Measure your shaft accurately and fit the correct bearing.
 
Just replaced the cutless bearing on a Malo 36, good advice from a fellow forumite pointed me at a bearing size of 30mm by 1 3/4 inch, which fitted perfectly. Mixed metric and imperial sizes are available.

Perhaps a 1 inch by 30mm bearing could be found?
