I have a aq125a volvo penta. It runs fine at a slow speed. When I go fast, it overheats anti-freeze. So I put in a new thermostat, a new impeller, and clean out the heat exchanger which really wasn’t dirty in the first place. Last year when I changed the oil thru the dip stick, the hose fell into the oil pan. I guess. Didn’t have any problems last year, but this year I overheat when I go fast. Could the problem be the hose that fell down the dip stick? I was told no.

Domesticated cats are descended from an undetermined species of wild desert cat and can tolerate heat pretty well. But since human intervention has led to the breeding of so many different coats, the long-hairs are not as able to cope with extreme heat as their short-haired desert ancestors. Your cat can certainly suffer heat stroke or even heat exhaustion, which could lead to death if not treated immediately. I've lived in hot places and had a few long-hairs through the years and I always had the vet tech shave their bellies (from collar bone to genitalia) and inner legs during the summer. That way, they maintained the fur they needed for protection from the sun (yes, cats can sunburn if shaved), yet, it made it possible for them to find a cool patch of grass under a tree or a nice bit of tile in the kitchen to lay out on and cool off when they needed to. Keeping cool water available at all times is also essential. Hope this helped and stay cool! And btw, your kitty is gorgeous!
Did you clean both the salt and fresh sides of the heat exchanger? I assume you replaced the salt impeller, have you checked it is pumping well? I'm using salt because I don't know where you are running the boat. What about the engine circulating pump, is it looking OK? Is coolant being blown out of the reservoir? If so, you could have a blown head gasket, or a crack somewhere. The lost tube is not going to cause overheating, but if you ever have the engine out, I'd be removing it then.
