    10-blade Vs. 12-blade Impellers

    I have two part numbers according to Jabsco. One has 12-blades #22120-0001 and the new part number is #18777-0001 but it has 10-blades. Which should I get? Is the 10-blade preferred for some reason?

    Proper RPM for my Volvo Penta AQ271C?

    When properly trimmed and full throttle, my boat's RPM according to the tach on my dash says 4000 RPM. Is this acceptable? I only ask because I seem to remember someone say in my travels that it should be between 4200-4500 RPM. I would love to get it up to 4500 RPM. Could the speed limiter...

    I have the AQ290 Volvo Penta outdrive and it needs the water connection housing replaced. Does anyone know if you need to drop the intermediate drive to replace it? I have never worked on this drive before so I am clueless what it will take to do this task.
