Trim “In” Angle Adjustment
WARNING
Boat operation with outboard trimmed to the full
“In” trim angle [not using the trim angle
adjustment bolt] at planing speed may result in
undesirable and/or unsafe steering conditions. A
water test for handling/steering conditions is
required after any trim angle adjustments.
IMPORTANT: Some boat/motor combinations not
using the trim angle adjustment bolt and trimmed
to the full “In” trim angle position may not exhibit
any undesirable and/or unsafe handling and/or
steering characteristics at planing speed. If so,
not using the trim angle adjustment bolt may be
advantageous to acceleration and planing. A wa-
ter test is required to determine if these character-
istics apply to a particular boat/motor combina-
tion.
