Operation of the Trim Tab
System may require practice to attain
a level of profi ciency. DO NOT operate
either trim tab to its extreme lowered
position suddenly. This may cause the
bow to lower to an unsafe position while
heading into or away from waves, which
may cause “swamping” of your yacht,
resulting in possible injury or death. DO
operate the trim tab switches with short
“bursts” until the desired “Running At-
titude” is obtained.
Maintenance of the Trim Tab System is
as follows:
Silverton recommends painting the trim
tabs with good quality, antifouling bottom
paint. DO NOT paint any hinges or the
moving parts of the cylinders.
To reduce the risk of electrolysis and
galvanic corrosion, Silverton recom-
mends the installation of sacrifi cial zinc
anodes on the trim tab plates at least
once a year, preferably during prepara-
tion for spring launch. DO NOT paint the
sacrifi cial zinc anodes.
Periodically examine the trim tabs for
accumulation of underwater growth and
clean as necessary.
Periodically examine the trim tab pump
and hydraulic lines, which are located
in the bilge area, for leaks (See Me-
chanical Layout on Page 155 and 156,
which illustrates the location of the trim
tab pump). Tighten connections if leaks
are noted. If the hydraulic lines appear
worn or chafed, contact your Silverton
dealer for inspection and replacement,
if necessary.
