Update to Heat Exchanger project

Thanks, Steven! I thought about measuring the output as you described, but it did, indeed, seem like an overly-complicated procedure. Flow LOOKS (??) good, but with no prior experience, I really dont know.

I think you're onto it though, with the heat exchanger being clogged by something. KISS it, right? Thats kinda been my process. Start with the easiest and most logical stuff then move forward if that doesnt fix the problem. I'll know more as I remove the alternator (easier access to the heat exchanger), change the fluid, replace the belt, install new thermostat, and pull the exchanger to see what's going on inside there.

If all that doesn't bring the temp down, I'll have to look into the exhaust side: manifold, elbow, hoses, lift muffler. I'm hoping it doesn't get that complicated, but you never know!

If the mast is out this would be the time to replace the chain plates. It should only take a half a day to remove them. And it’s easy to get new ones fabricated. Plus another half day to put them back in

Not sure if this has been discussed but a bad head gasket can cause overheating too.

Yes, Sir.  Mast should go up in March, hoping to have all chainplates finished before then.

I hope I can find a simpler solution, Franklin, but a head gasket is also not out of the question.

I hope you really enjoy cruising. I cruised for 8 years, 6 on a Hunter 376 and 2 on my Whitby 55' due to me developing a family in Tonga. I gotta tell ya, Whitby boats are fantastic. We are currently in the process of buying a house in Colorado. I hope I don't have to sell the boat down the road as we are planning on giving it another try to sail around the world in 5 years. If I don't get another chance I'm ok with it but maybe I can find a way to make it back out on the waters and see you out there.

Whitby 55s are so fantastic that I am willing to pay 35+K in slip fees just to keep the boat for a possible chance I can take her out there again in the future. They only made 3 of these so I know if I let her go, I will never be able to sail on such a wonderful boat again. I think so much of this boat that I hope I can hold onto it and give it to my son. I know I would sleep much better knowing he is on a Whitby.
