My water pump on the starboard engine is not impossible to get to, but almost. I flushed with Barnacle Buster last year. I didn't want to remove the impellers, so I just used there adapter to suck it in through the strainers and when it was all sucked in, just shut off the engine. Let it sit for about 7 hours and then started the engines. One engine dropped 5 degrees and the other engine dropped 10 degrees. Well worth it I believe. Then did both A/Cs. The sit and soak method may not be as efficient as the recirculating method, but it sure was easier.
