ENGINE REV-LIMITER
IMPORTANT: The engines listed in the following chart are equipped with a rpm rev-
limiter that is set to an upper (or limited) rpm amount. This limit is slightly above the
normal operating range of the engine and is designed to help prevent damage from
excessive engine rpm. When the engine reaches the rev-limit rpm, the horn will
sound. Once the rpm drop into the recommended operating rpm range, normal en-
gine operation resumes.
