First ; Full disclosure. A few years back I pulled my Afour , made a lot of improvements , and hung out on this forum a lot.
4 years of flawless function allowed me to become a slacker. My maintenance became sloppy ; I barely kept up on the forum.
On Independence day my Afour stopped making water. I let her cool , limped back to the marina , and got on the phone to Ken. When I pulled the water pump I was relieved to see that the impeller blades all seemed to be in the pump housing. New inpeller , new grease , she started batching water like a champ. Problem solved - or so I thought. The first time I ran under load the temp rose to 200-205. Not good.
Good water discharge tells me that there is no significant blockage. I am sorry to say that I cannot testify to the temp reading on the old original gauge prior to the pump failure. The gauge is hard to see given it's location ; I am prone to opening the galley counter and doing a visual and sniff test periodically. When showing 200 nothing smelled hot.
Should I try removing the thermostat? Worst case scenario is running too cool. How cool is too cool? I think I know where I can borrow an infra red heat sensor. Where on the engine , thermostat housing , or hoses should I look for heat readings?
Any input will be appreciated by this negligent Afour operator.
