Spent week on Lake Powell, North end, exploring canyons down through Escalante. Boated out to marina to get ice, would not re-start to get back to camp. Checked fuses, pulled water separator/filter and drained, pulled check valve on top of tank and verified ball/spring were free, fuel pump ran and shut off, but not much spray from injectors (TBI), more like a dribble (definitely not even close to today's spray). Unable to get more than sputtering. Able to get towed back to launch and pulled boat, paid marina to run us back to camp and pick up equipment. Tried to restart afterwards and still no start.
No issue day before with 60 mile round trip and numerous stop/starts, just suddenly no start. Towed home and started troubleshooting today, started right up no issues.
Pretty sure fuel pump is fault, going to pull pump and cooler tomorrow and check for debris in cooler, Is there a reason pump can't be replaced without changing cooler? Aside from replacing filter and rechecking all electrical connections, anything else to check?

2001 Sea Ray 185, 4.3L TBI, 130 hours on boat

And the only bad weather was when the boat had issues.

I did, only explains what's avail, not why. Can only guess cooler restrictions lead to failed pumps/ warranty issues??

Very few manufacturers will divulge WHY a part is superseded, just that it is.... But as you summised, it's usually a problem with the part.
