XR Sportmaster drives
 

Question for the experts.....Just bought a 26 daytona with merc 525, Imco standoff, XR sportmaster w/ITS. Boat has 60 hours on it. Couple of questions:

With fairly conservative driving, whats the expected life span of these drives with current setup?

What type of maintanance should I be doing monthly, annually, etc for the drives?

Boat currently has a 3-blade lab prop, not sure on the pitch. Max rpm right at 5k. Does this seem about right? Also what are some other options for this setup prop wise?

Thanks for your help!

with that power should last along time, sounds like the wrong prop to me,would think 4blade would provide better performance. no expert just worked on a few
