SkiprJohn, thanks for the offer but I could not resist buying
a new heat exchanger
replacement from TAD together with a Exhaust
. I installed the assembly on Sunday and checked everything twice before going topside. I cringed when I turned the key......She started right up. We checked for leaks
; the exhaust
seems to have a bit more pressure. The real test was throttle. I held my breath and pushed the lever....WOOOOOHOOOO! She reved past 4K revolutions. She had tons of power. We had to take her for a spin. We tiddied up and went. Before she would not go past 2 knots so getting to 4 knots was my goal. We revved her to up 2200 revs and we achieved 4.5 knots. I was in heaven. Temperature-wise in our entire run, she did not get past 140 degrees. I am changing the thermostat next but I am so happy, I cannot put into words. She runs like a dream.
I want to thank all for your ideas, help and encouragement. I have a "new" boat. Now onto sailing questions and posts.....thanks to all again!!!
