Protection from the Elements
Yamaha improved their legendary Ultimate Corrosion
Protection System for the F40A. Yamaha’s proprietary
alloys, ACP-221 paint process, and freshwater fl ush device
are just the start. Multiple sacrifi cial anodes in and on
the power head, mid-section, and lower unit, a special
ACP-221 paint process, and a specially-painted and treated
exhaust system means better long-term protection and
maximum value.
All F40A models are equipped with an Engine Control
Module that interfaces with Yamaha Diagnostic System
software. This provides a view of selected past and current
running conditions, to help technicians provide a complete
and accurate diagnosis.
All F40A outboards feature a large, on-engine water
separating fuel fi lter with a water sensor. Used in
conjunction with Yamaha’s optional boat-mounted
10-Micron Water Separating Fuel Filter, it helps separate
water and contaminants from the fuel before they can
reach the outboard’s other fi lters and fuel injectors.
The F40A features a proven one-piece cowling with an intake
air drain system, to easily and effi ciently drain away any water
that enters the cowling during normal engine operation.
Incoming air is routed through a labyrinth of passages that
help trap and drain water before it enters the engine’s intake,
for maximum reliability.
