Mercury Marine and Quicksilver propellers for engines 40 hp and higher feature the Flo-Torq hub system with a Delrin sleeve, which is resistant to the effects of oil, the company said in announcement to boaters in the Gulf region.

Running engines with Delrin hubs in oil-tainted waters has not been shown to shorten the life of the propeller, Mercury added. It said exposing rubber hubs to oil can soften and weaken the rubber, which can cause the hub to fail.

Mercury reported it recently filled an order for 90 engines (90 hp) for boats in the Gulf of Mexico cleanup operation.
