[QUOTE="handyandy, post: 439561, member: 18942"] What do you have? four stroke 60/40 of some kind? Mercury/quicksilver who are the ones that make the three blade 6 7/8 stainless impellers. The new ones they make have been machined differently to allow the new 60/40 four chokes to be able to spin up to their optimal rpm range. THis is because the 60/40 four chokes didn't have the power to spin the old style non cut back stainless impellers in there optimal rpm range. So if you have an old style stainless impeller that isn't one of cut back ones don't cut it back sell it to me and go buy a new impeller that is a cut back one meant for a four choke. They're was thread with pictures of the two style 6 7/8 impellers that show the difference. [/QUOTE]
