I use mine a lot but If they make it that far, start thinking I need to get rid of them around the 5 year mark.
The F250 Yamaha is as solid a motor as they come. That being said, I am considering the new F300. For the pair I can drop over 100 pounds and gain over 100 horsepower upgrading from the 250s. And you can get the electric shifters with them. 12 years with Mathers electric shifters in my little boat and the cable shift on the big boat feels positively primitive.
