WOT OPERATION RANGE TABLE
If the engine RPM exceeds the recommended WOT range, replace with a larger pitch propeller.
If the engine RPM does not reach the recommended WOT range, replace with a smaller pitch pro-
peller.
NOTICE
Do not run the engine at a speed which exceeds WOT range, as the engine could be dam-
aged from overload or over rev.
* The engine rpm at WOT operation will be usually changed about 150 rpm if the pitch of propeller has been
changed one inch.
However, the change of rpm varies due to the propeller type, water type (salt or freshwater), boat type
(weight or hull shape), etc.
* The maximum engine RPM will increase when the outboard motor is trimmed out.
