Outboard Motor Mounting Brackets Explained

An outboard mounting bracket lets you fit an auxiliary engine to a boat that doesn't have a built-in transom mount — most commonly seen on sailing yachts running a portable outboard for auxiliary power.

Auxiliary brackets for sailing yachts

These fold or swing the engine clear of the water when under sail, and back down into the water when needed under power — essential for auxiliary setups on yachts without an inboard engine.

Transom brackets

Simpler fixed or lift-up brackets for dinghies and tenders, matched to the engine's clamp screw width.

Weight ratings

Every bracket has a maximum engine weight rating — check this against your outboard's dry weight, with margin, since brackets take significant leverage force when underway.
