Your calcs are otherwise right, except that its a boat.
IF you use it as (open) sea, frontal wave action causes the whole mass *and inertia* of the boat to be transmitted to the bearings.
In short, its an impact load.
As such, manufacturers who make these things commercially, use a rating of 5x to make anything meant for sea use.
This is what has been proven necessary through experience.
For occasional hobby use, like almost all pleasure craft, it may last fine.

Hi Jim,
Just to be clear I am not using a separate thrust bearing. I'm using the Lynch motor bearings to take the loads, which there are two off in the motor of the types below,
3204-2RS or the 3204-2Z.They differ I think by seal/friction/lube.3204-ATN9 SKF Double Row Angular Contact Ball Bearing - Polyamide Cage :: BearingBoys.co.uk
