I just tried a 15 1/4" by 19 on a wellcraft 20' center console with a Merc 200 EFI,4800 top rpm.Motor should do 5200 or more with a 17",a 14 1/2" by 19 should do good.

Hi,<br /><br />I have a Merc 175 o/b. I finally got worked out the best prop for my boat... , My Boat is a 21'foot walk around... When I bought it, it had a 13 3/4 by 17p. At WOT I was over 6000 rpm, 36-38 mph.. WOT S/B 5200 to 5600... I am now running a vented 14 1/4 by 20p SS, WOT is 5200 loaded (46MPH) and 5600 empty (52MPH)... I know that Stainless Steel cost the big $$$ and to try 4 or 5 diffrent props can add up! Your local dealer won't just let you try them either.. So here is what I did... I bought, tried and sold them on Ebay!!! I bough an aluminum 14 1/2 x 19, was ok, droped my rpm, but was a dog out of the hole... Sold my 17, bought a SS 19p, ok out of the hole, but over tach, sold it, got a 14 1/2 x 21p vented, got out of the water better than the 19 aluminum but was just under 5000 rpm WOT when loaded, Next! Ended up with my current 14 1/4 x 20p and kept the aluminum 19 for a spare... After all said and done, I think I broke even on the aluminum spare and less than $200 for the SS.<br />I found each inch of pitch was about 220 rpm, every 1/4 inch of diameter larger was about -30 to -40 rpm.. The diffrence between aluminum and SS was about 1 full pitch, a 19 alu was = to my 20p SS (RPM only, not speed(alum 5mph less) Vented props make the boat come out of the water faster, like a 17p would. The vents allow the prop to spin up faster, then it stops venting at higher speeds... hope this helps!!

Go to your local Merc dealer and borrow some used props to test out. I think you need a Quicksilver Mirage II in a 19 pitch for your boat. Stainless Steel with vent holes. I would bet you could spin a 21 pitch in the same brand, but you would probably want the power of the 19 for offshore in the big swells.
