4-blade 6-15hp High Thrust Aluminium Propellers to suit Mercury Mariner Outboards with 8 tooth spline

A choice of titanium-aluminium 4-blade High Thrust propellers from PolaStorm in black with pressed hubs to suit various Mercury and Mariner 6-15hp outboards with 8 tooth propeller shaft spline. These large 10" inch diameter 4 blade High Thrust propellers from PolaStorm are ideal for river cruisers, workboats, yachts and other large, low speed craft. As well as greater blade area, they have a larger outer hub than the standard type propellers, allowing exhaust gasses to exit in reverse without washing over the blades - improving thrust when in astern. PolaStorm propellers have some additional features such as stronger blades due to the material used / casting process, plus a durable powder coated finish.
