Bearing sizes for CMB

[FloridaScaleBoater]

Can anyone help me out with engine bearing sizes for a CMB RS 21 outboard
(Rear exhaust, carb/intake through the crank)
Thanks in advance
Rick

Hey Rick,
Not sure on the numbers but Jon sells them (TNTboatracer).
Should be the same as the wrap around inboard RS engines from what I remember, minus the PTO bearings.

Yes sir,
That is actually how it's being rebuilt, as an inboard.
Thanks, I'll hit Jon up

Depends on which stage of your engine, i known its comes with 13mm and 14mm crankshaft. 13mm shaft need 13x24x6 and 14x25x6 is for 14mm shaft. The front is same on 7x19x6.
