Abstract
A boat propeller sled comprising a spine, straps attached to the spine, and rails attached to the spine. The straps are sized to fit around an outboard motor lower unit, and to securely attach the spine to the lower unit. Each rail comprises a base attached to the spine, a forward ramp attached to the base, a runner attached to the forward ramp, and a rear ramp attached to the runner. In the preferred embodiment, the bases are attached to the spine at an angle of approximately ninety degrees, the forward ramps slope forward at an angle of approximately sixty degrees relative to the horizon, the runners are substantially horizontal, and the rear ramps slope upwards towards the rear at an angle of approximately thirty degrees relative to the horizon.
Claims15
A boat propeller sled comprising a spine, at least one strap attached to said spine, and at least one rail attached to said spine, said rail comprising a rear ramp attached to a runner at a rear ramp angle of one hundred fifty_ degrees plus or minus fifteen degrees whereby said boat propeller sled may slide backwards without said rear ramp digging into a surface over which it slides.
A boat propeller sled comprising:
- a spine;
- at least one strap attached to said spine;
- at least one base attached to said spine at an angle of approximately ninety degrees;
- and
- at least one rail comprising a forward ramp attached to one extreme of a runner and a rear ramp attached to an opposite extreme of said runner, said forward ramp being attached to one said base, said forward ramp being attached to said runner at a forward ramp angle less than one hundred eighty degrees and greater than ninety degrees, said rear ramp being attached to said runner at a rear ramp angle of one hundred fifty degrees plus or minus fifteen degrees whereby said boat propeller sled may slide backwards without said rear ramp digging into a surface over which it slides.
A boat propeller sled comprising a spine, at least one strap attached to said spine, and at least one rail attached to said spine, said rail comprising a base attached to said spine, a forward ramp attached to an extreme of said base opposite said spine, a runner attached to an extreme of said forward ramp opposite said base, and a rear ramp attached to an extreme of said runner opposite said forward ramp at an angle of one hundred fifty degrees plus or minus fifteen degrees whereby said boat propeller sled may slide backwards without said rear ramp digging into a surface over which it slides.
A boat propeller sled comprising
- a spine;
- two straps attached to said spine;
- and
- two rails attached to said spine, each said rail comprising a base attached to said spine, a forward ramp attached to an extreme of said base opposite said spine, a runner attached to an extreme of said forward ramp opposite said base, and a rear ramp attached to an extreme of said runner opposite said forward ramp at an angle of one hundred fifty degrees plus or minus fifteen degrees whereby said boat propeller sled may slide backwards without said rear ramp digging into a surface over which it slides.
