Wow...thanks Ferm!!...'89 looper and never got it past 3 grand, so you may be on to something...plus the diverter valve you mentioned has a small, steady leak and I don't know if that's a possible culprit here or not...the pisser stops pissin', but if you disconnect the back tube from the diverter that goes to the starboard t'stat(plenty of water coming outta there) and then reconnect it, then it starts pissin' again...
IF the t'stats are faulty, could they be closing at the wrong time and shutting the flow off?...Spare put a new water pump on just after we hung it on the boat, so confident no issues there...
Thanks for your thoughts...
