RPM REV-LIMITER
IMPORTANT: When selecting a propeller consider this additional information, if ap-
plicable:
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 operat-
ing range of the engine and is designed to help prevent damage from excessive en-
gine rpm. Once the rpm drop into the recommended operating rpm range normal en-
gine operation resumes.

Hot Water Heater Installation Recommendation
IMPORTANT: When connecting a cabin heater or hot water heater, certain require-
ments must be met:
• Supply hose (from engine to heater) and return hose (from heater to engine)
MUST NOT EXCEED 5/8 in. (16 mm) I.D. (inside diameter).
• Make heater connections ONLY at locations indicated in the following informa-
tion.
• Refer to manufacturers’ instructions for complete installation information and
procedures.
• Do not reposition engine temperature switch; it must remain where installed by
factory.
CAUTION
Avoid a performance loss and/or possible engine damage. Engine coolant must
flow continuously from the engine intake manifold to the engine water circulating
pump. NEVER close-off or block the coolant flow to or from a heater.
All heater installations must be plumbed in series with the supply and return con-
nections.
