TRIM TABS
Trim tabs are located on the outer edges of your yacht
transom below the swim platform. All mechanical and
electrical connections should be periodically checked for
tightness, corrosion, and chafi ng. If a malfunctioning tab
is suspected, run each tab in and out while someone looks
at each tab to make sure it is moving up and down the
proper distance. Replace any zinc anodes mounted on
trib tabs when at one half their life as determined by
size. Check anodes twice a month.
Check the hydraulic power unit fl uid (HPU) level. The
pump is located in the bilge (sump) close to the transom.
To refi ll, remove the lexan cover and fi ller plug. Fill with
any type automatic transmission fl uid (ATF). The fl uid
level should be 2" from the reservoir bottom.
The trim tabs may be painted for corrosion protection.
Do not paint the anodes as they protect the tabs from
galvanic corrosion.
