It is a good idea to take your boat out onto open water
shortly after you get it and experiment with the trim
tabs. After you get your boat onto plane, set the tabs
in various positions and note how your boat reacts.
This will give you a feel for how the trim tabs work.
D. Trim Tab Maintenance
Regularly check for any water intrusion where the
interceptor trim tab units are mounted. When needed,
paint the external surface of the interceptor unit with
anti-fouling paint. Note: Do not paint any moving
parts, e.g. the blade! Refer to the manufacturers
information for additional maintenance infor mation.
E - 7 ENGINE INSTRUMENTATION
A. EVC System Display
The V458’s helm station is equipped with a two
Electronic Vessel Control (EVC) system displays. One
for each engine. This instrument displays operating
information about the engine and allows you to
communicate with the engine’s electrical system.
Close observa tion of the informational displays could
save the engines from damage. See Figures E8, E9
& E10.
When run ning at high en gine speeds, be sure
the trim tabs are in the full up posi tion. Trim tab
ac tion should be only enough to com pen sate
for any list ing. Trim tab ad just m ents at high
speeds are ex tre mely critical. Be prepared to
slow down should handling difficulties arise.
When running in a displacement (very slow speed)
mode, better efficiency will be obtained with the trim
tabs in the full-up position.
Remember that most boats react very slowly to trim
tabs. Often boat owners do not give trim tabs time to
work. Press the trim tab switches for only one second
at a time and then allow some time for the boat to
react. If the boat is still listing after a minute or two,
press the trim tab switch again for a one second
interval. The labels on the trim tab switches indicate
what you want your boat to do, not what you want
the tabs to do.
