INSTALLATION
Correct and secure installation is
essential for safe boating and good
performance. Follow the installation
instructions provided in this manual.
POWER REQUIREMENTS
Before installation, check to be sure
that the outboard motor does not
exceed the recommended maximum
horsepower for the boat on which it is
to be installed. Refer to the boat’s
certification plate for recommended
maximum horsepower. If the
certification plate information is not
available, contact the boat dealer or
manufacturer.
For most applications, the outboard
motor should have a horsepower
rating which provides 80% of the
maximum recommended horsepower
for the boat.
BOAT TRANSOM
REQUIREMENTS
Honda BF25D and BF30D outboard
motors can be installed on a boat
transom having a thickness range of
1.3 – 2.2 inches (35 – 57 mm).
INSTALLATION POSITION
Install the outboard motor on the
center of the boat transom.
The antiventilation plate of the
outboard motor should be 0 – 2 in
(0 – 50 mm) below the bottom of the
boat.
The correct dimensions differ
according to the type of boat and the
configuration of the bottom of the
boat. Follow the manufacturer’s
recommended installation height.
