You don't say if you're happy with the performance you're getting with your existing 21"p prop. If you're happy with it, the the prop you are looking at, with a part number that ends in 21p, should give you similar performance - IF - it fits.

Yes it will fit as BlackMax is Merc's trade mark for their alum series props.....

How old is the old prop? Mercury made some changes to there prop lines in the late 70s, the thrust washers and the hardware at the propnut end differs between the older and newer.
