3.4 CORROSION PROTECTION
See EOM 55-127 In addition to transom zincs, there are engine and drive zincs and care must be
taken of the drive housing and coating of the propulsion unit. Be sure to inspect and recoat if
there are any scratches or whenever the boat is hauled. The timing for replacing zincs varies
depending on the characteristics of the seawater, the amount of electrical current in marinas, or
could indicate (if excessive wear is noted) an electrical short on the boat, etc. Inspect the engine
zinc periodically at the time of oil changes and remove the corroded area on the surface,
replacing them when deteriorated to less than 50% of original size. Otherwise corrosion-cooling
system will occur and water leakage or parts breakage will result. Be sure to close the raw water
before removing a plug to replace an engine’s zinc.
3.5 ENGINE AIR INTAKES
Diesel engines use a large quantity of air for
combustion. The engine of the 40z gets this air thru grills
under the cockpit coaming, both port and starboard.
3.6
ENGINE CONTROL/DISPLAY PANEL
The VesselView Display Screen allows the operator to perform settings and choose information
displayed The entire Mercury SmartCraft Owner’s Manual (MOM) is devoted to the operation of
this display panel. Ignore the Genset Section which is only for ONAN generators made by
Cummins. There is no interface with the optional Northern Lights Generator(s) on the 40z.
3.7 THROTTLE/SHIFT CONTROL (See MOM 22)
The Standard 40z is equipped with the dual-engine, 2-lever DTS Trackpad Yacht Control
incorporating SmartCraft electronic remote control (ERC) which has a DTS trackpad integrated
onto the base of the control. The DTS trackpad is used to enable or disable features of the DTS
system, including auto-synchronization, throttle only, etc. The 40z is NOT equipped with the
TROLL feature.
