Impellers do see quite a bit of spinning, but to replace every other year in my humble opinion is a tad overkill. Safe?....yes.... But...the rubber is inside of a housing so UV rays will not affect it, dry rot is extremely minimal, and being that when the motor is properly run, there is water lubricating the impeller within the housing.
Unless you are out day in and day out with the motor running consistently such as trolling, I see no reason to replace for 3 years. I would say for the average fisherman (tongue firmly in cheek here) that most of us who cast probably put 50 hours on the main motor in a year...the trolling crowd obviously would be more..
If you have a water pressure gauge installed, the telltale would be when you see a drop in water pressure as compared to previous use/previous year. If the pressure is staying within a PSI or so from the previous year, you'd be safe.
