Well , i have some impeller but i have a question.....

I donīt looking only for top speed...i donīt have more time to test before send the boat for race and i donīt know what impeller install, Solas 15/22R or Skat 14/19 3 blade...... The engine works around 8.800RPM.

About my experience ever i get better result with 4 blade impellers but maybe i can try somthing different

Best regards
