How old are the exhaust elbows and risers? Crusader OEM parts should have the date code cast on the part.
Elbows and risers are raw water cooled and need replacement every five to ten years depending on how salty your raw water is. Have you tried backflushing the raw water side? Have the fluid coolers been changed or acid washed? Years ago I had a small piece of cellophane wrap clog the fluid (oil or tranny?) cooler on a 270 Crusader. As the fluid cooler was the first place raw water flowed after the pump, everything downstream was running hot. And get an IR temp gun as previously suggested. Bob
