    Depends on your boat use. If you travel miles on the water I would check it every trip until I was sure it wasn't changing. If there was ever water in it or if it was ever low then I would continue every trip. Then I would get it fixed.:smile2:

    I change my lower unit oil every fall do to condensation getting in there and I don't want to let it set over the winter with water in it. On electric shift models it should be changed twice a year and it takes a thinner type oil then manual shift units. Manual units are Hi-Vis 80W-90 and electric's are type C.

    I drain my lower unit every fall and fill it with fresh lower unit grease (cheap stuff) for the winter. Then in the spring, I drain out the cheap stuff and refill with a lower unit grease I trust.
