2 1/2 inch offset no wedge
A feature which is used on the lightest of boats.
Allowing the engine to be raised to its maximum height
without putting the weight of the engine too far behind the
transom which could create too much bow lift.
2 1/2 inch Offset with Negative 6-Degree Wedge This
design can be used when the transom of a boat is too steep
of an angle to allow the outboard motor to perform properly.
For example: an 18-degree transom when this design is
5-inch Offset No Wedge
This option desirability will vary from one boat to another
depending upon weight and length of boat. Some outboard
motors have a limited trim angle and the 6-degree wedge may
not allow for enough bow lift. By setting the plate at the
no wedge design, it will give maximum bow lift.
5-inch Offset with 6-Degree Wedge
Jacking bolts- allow motor to be moved to any
height. No need to take boat out of the water.
Offset- positions motor 5 1/2 inches behind
transom. This allows prop to run in cleaner water, away
from the turbulence and bubbles created by the hull.
This helps stop slippage of prop, and helps stop torque
in steering wheel at high speeds.
Trim-In- this allows motor to be trimmed in or
down 6 degrees more than if mounted flat on transom.
Helps stop low speed porpoising. Balance load better.
Light-weight- approximately 25lbs., constructed
of aircraft grade aluminum and stainless steel.
Anodized- anodized black finish to prevent
corrosion. Anodize also lets paint stick to aluminum if
painting is preferred.
Narrow designed- only inches wide, make this
plate possible to fit the narrowest of transoms.
Fits V-6- pre-drilled to fit all late model
V-6's. Can be modified to fit any size outboard.
Converting the new 4 in 1 is as easy as dropping anchor!
