4 blade vs 3

[D@lton]

On my Parker 23DVCC I currently have the factory 3 blade ( 15 1/4 - 17 )that came with my 250 4-stroke Yamaha. I was wondering what replacement to a 4 blade (pitch and size) I would start with to achieve the following:

I know I'll lose some top end, but I'm looking to be able to stay on plane at lower speeds as well as better hole shot.

Any Suggestions?

Had the same problem on my 2520scxl. Tested 5 different props. Put the Merc 4x17 on it. Lost 200 RPM WOT, STAYING on plane at lower rpm, better MPG. Grouper Jim started a thread on Props. Worth reviewing.

Might need a 19 pitch Rev4 with the 250. Whatever pitch you have now with the black Yamaha 3 blade, use the same with the Merc Rev4...this is assuming you're reaching full RPM with Yama prop. If you will raise the motor a hole you might even gain a MPH or so. You'll certainly cut down on wake, I did.

"grouperjim" has a heavier 23DV cabin boat w/250-4 and runs the 17 pitch Rev4. I have 225-4 23DVCC and use the 17.

Of course, if we had Suzukis with the special lower unit we could turn props maybe 2 feet in diameter! :lol: :lol: :lol:
