Where can I find hard facts? My adjuster is going to prorate on life expectancy, but I'm wondering how he figures this out? He's sending out for an oil sample. That's ok since I just put in new Amsoil this year, so it's going to come back clean and well taken care of I hope.

I suppose it depends on how you care for them. We have never come close to wearing out a transmission. Change the filters and oil on a schedule recommended by the manufacturer, and keep your shifts below 1000 rpms. Our 15 year old Tiara showed no signs of wear when we sold it. Shifts were crisp sounding and there was no slippage in big seas. Oil was nice and clean with no smells or leaks.
 
You could ask ZF to give you that information:

I've been boating for 35yrs and never heard of any of them coming to the end of their serviceable life from "old age". It has always been from running low on fluid, the wrong fluid, propeller strikes, or being jammed in/out of gear at high RPM's.

Clearly there is more to the story as an Adjuster is involved.

The basic problem is your boat is 17 years old and the way the insurance industry works is to depreciate everything on the boat at the same interval ........which is the same way they do it with automobiles. That's why 17 year old boats don't get brand new engines or transmissions unless the owner kicks in the difference. My guess is that useful life number you are looking for is around 20 years and/or 1,000 hours.

While a number of us have boats which exceed 20 years and 1,000 hours.....I certainly don't expect much from Geico unless the boat sinks.
 
Call Travelers insurance! None of that BS and full value coverage and not outrageous prices. Boat US and Geico.... well you know.
