* L/H rotation model has the same RPM as R/H model.
If the engine RPM exceeds the recommended WOT range, replace to a larger pitch propeller.
If the engine RPM does not reach the recommended WOT range, replace to a smaller pitch propel-
ler.
NOTICE
Do not run the engine out of WOT range, the engine could cause a damage from overload or
over rev.
* The engine RPM at WOT operation will be usually changed about 200 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 fresh water), boat type
(weight or hull shape), etc.
* The maximum engine RPM will increase when the outboard motor is trimmed out.
