My brother is repowering his 1998 Outrage 17 II with a new 150 HP Mercury. What polished stainless steel OEM Mercury propeller is appropriate for this application?

Paul - That boat is going to be fast. I drove a 17 II with a 135 Merc on it and it moved. Hope he's getting the EFI version.
If overall top speed and performance is his objective, I would recommend the 19" Laser II, which is rated for 2400-3000 lb load range, speed range 42-49. A 21" would cover 2100-2600, so it's possible that would work, speed range 49-55. He should install a Rite Hite transom jack so he can easily adjust engine height for use. I use Mercury Laser II props on both of my Whalers.
If heavy duty offshore running is in order, a 4 bladed "Offshore" gives slightly less top speed (which may not matter), but otherwise better holding, lift and acceleration.
For super smooth heavy duty pulling, such as skiing, the 5 bladed prop is in order, but also slower top end.
offshoreperformance.com, in Ft Myers FL, has the best prices in the country on Merc performance props. Great service too. About $400, with hub of your choice depending on engine brand.

Thank you for the information. He's negotiating a deal on the engine and rigging, and I'd like to see him get the right propeller the first time. He prefers purchasing the propellers and accessories supplied by the engine manufacturers.
He usually runs the boat lightly loaded (two people and minimal gear), and top speed would be a priority. He's not a fan of transom jacks, so will a direct transom mount affect the choices you've listed?

Then I would recommend the engine be installed in the third (middle) set of holes. The Laser II would be the prop choice. Pitch is always somewhat of a guess, and requires some trial and error.
