Non-thru

Non-thru

This type of propeller is predominantly found on low horsepower outboard motors where the smaller size and simplicity of the propeller gearcase combination is more practical. By not having to put exhaust ports in the prop, the prop hub diameter can be smaller as well as the corresponding gearcase torpedo diameter. This makes for a simpler unit. In decades past this design was not uncommon on horsepower as high as 50, but these days they are usually only found on motors with less than 8 horsepower. Another common element of the prop design is that these props often use a shear-pin instead of a splined drive to drive the prop. Again, a shear pin is a simpler to manufacture arrangement. Piranha does not make very many propellers that can be used with non-thru-hub exhaust motors. If the prop in question is a pin-drive prop, then Piranha DEFINITELY will not have a prop available. Otherwise, a Piranha may still be applicable. Please call for available applications.
