I have a 1992 concept 21.5 center console sport fish that is now concidered the 23. I'm running a 98 johnson 225 on a hydraulic jackplate. Im looking for some advice on the best prop to run. I have a omc raker 20p but its not enough cupping or pitch. When I raise the motor it slips a lot. The raker 22 has more cupping which should help. I know most concepts are running mercs but any tips would be greatly appreciated.

Wrong site for non merc stuff. What props can you run? I would say a rev4 if it will bolt up is a fantastic o/b prop. Call bblades he Wil know.

I think the Revolution 4 is a great stock alternative. Using the correct hub kit we can test one through our test program.

Just call us when you can to discuss the options.

Thank you,
Brett

You can contact Joey from concept directly and him having all the specs that are needed for the boats to be dialed in I'm sure he will be able to lead you in the right direction. The number should be on their conceptboats.com website

Good luck
