Not on a Checkmate.
If you're talking Mercury High-5, I've run one on my old Persuader. It was a GREAT ski prop, none better. Very low bow lift, slow on top end. Only good from hole-shot to mid range running.
If you're talking the new breed of high performance offshore props by Hydromotive or Herring, can't help you there.

5-BLADES
The trick to a 5-blade working PERFORMANCE wise is drive height... the boats running a raised X-demension respond well because of having the added blade surfaces pushing the boat when a lot of the prop is above the water.
Putting one on a standard drive height will typically slow it down but improve the holeshot and crusing efficency (mpg) if you choose the right pitch. Running a 5-blade deep puts a lot of extra blade surface in the water, improving thrust and reducing slippage... hence the merc high-5 working so well for watersports.
The trick is choosing the right 5-blade... and a lot depends on the blade size and shape!!! Typically, if you run say a 23p Mirage 3-blade, you would go to a 22p 4-blade Bravo 4, or a 21p 5-blade Maxis.... but not always! See what the prop manufacture recommends first...
