Installation
The M400 Marine ECU replaces the factory ECU on top of the engine.
Remove the factory ECU (three T25 Torx screws) and pre-assemble the
supplied mounting plate before the M400 ECU is fitted:
•
Screw 4 supplied M6 Stainless nuts on the studs
protruding from the top of the mounting plate.
These serve as captive spacers. (see right)
•
Invert the plate and ensure that the 3
rubber rings are seated on the rubber
bushes which are fed from the top side
of the plate. (see picture at right)
•
Place the plate with rubber inserts
over the plastic mounting bracket
on the PWC.
•
Firmly screw 2 x 6mm cap screws
with washers in the lower 2
positions, and 1 x countersunk
screw without washer in the central
position. Do not over tighten.
•
Ensure that the rubber mat with
hole is mounted over the centre
countersunk screw.
•
Fit the waterproof relay to the top right screw post
which protrudes from the mounting plate.
•
Fit the M400 ECU and place the 2 stainless steel
brackets onto the 4 screw posts, after first fitting
the rubber trim strips to the underside of the
brackets.
•
Secure the brackets (and relay) with 4 x M6
washers and 4 x M6 Nylock nuts.
