Tawcat - water is used to cool and lube your shaft seals. When your engine is not running, there is no water flow to the seals.
So, during your two hour tow, your shafts were spinning in the seals with no cooling or lubrication from water flow. Whenever you tow an inboard boat with dripless seals you should lock your shafts to prevent them from freewheeling. A pipewrench locked on a shaft and lodged against the bildge will prevent them from spinning.
BTW - most marine gear makers also recommend locking the shafts because your transmission gets no oil pressure without running your engines.
