Re: Sierra impellers conversion chart?

Dhadley,<br />Do you know of any aftermarket impellers that are better than Merc impellers? My 50 4S Mariner has an impeller about the size of one on my 53 3hp JW10 Johnson. I'm not joking. In fact, the 3hp impeller looks stonger and less feeble. The 50 impeller lasted about 1.5 years before getting stiff and not pumping at idle. It was cracked like one 15 years old but not worn at all...I'm NOT impressed with mercs impellers.
