Planing Foil: (Cavitation Plate)
Like all planing devices that bolt to the cavitation plate of an
outboard engine's gear case, the Allison Planing Foil will help
your boat to come on plane quicker and easier while allowing it
to maintain a slower planing speed. But that is where the
similarity ends. Unlike all other planing devices, Allison's patented
"forward-swept" trailing edge design does not catch
"prop-wash" spray that creates drag and forces the nose of the
boat down; thus slowing it down. Why would you buy a planing
foil that helps get your boat on plane faster if it slows you
down the rest of the way? The Allison planing foil not only allows
your boat to go faster once it is on plane, it saves fuel too
when compared to any other planing device.
The Allison Planing Foil is available in models to fit most outboard
brands and gear case styles. It comes with black powder-coating
but is available without the powder-coating for high
performance engines with exhaust cut-outs. It also comes
with necessary fasteners and spacers.
The "X" dimension of a stern-drive or engine height of an outboard
must have the cavitation plate at least 3-4" above the
bottom of the boat.
