we have a 2005 321. the access to the raw water pumpimpeller is indeed dreadful, made more difficult by the tiny bolts on the yan mar pump head. the speed seal cover is great. i found a jabsco small-size impeller puller tool that looks like a matching set of ‘claws’ attached to a screw mechanism. the claws insert to grab into the old impeller, and then the turning of the jabsco’s screw mechanism tightens the class and removes the impeller. to put the new impeller in, use a plastic wire tie around the outer circumference to bind the vanes smaller, so they slip easily into the chamber– and pull out the wire tie after the impeller is started into place. i am also thinking of cutting an access hole for the jabsco into the bulkhead of the battery compartment and fitting a removable waterproof plate. so the working screw end of the jabsco would be accessed by an easy reach into the battery box bulkhead then into the impeller. th small she impeller puller does fit very easily into the raw water pump body. i can only do this hole thru the bulkhead because we have replaced the huge 8 D batteries with several smaller group 31 s . so there is enough room for the impeller access panel…

fair winds to all..
