Truth????? New engines should be fine!!! For folks that have older motors I will make you feel better!!! At this time take a clean container and place under your skeg. Drain your lower unit and refill it with new lower unit oil specific for marine use. At this time your engines lower unit is protected. If you dont prepare your motor and maintain it properly. Then you can go to the shop and give away your money!!! 3-4 tubes of lower unit grease/oil and your good. If you have an older engine your rolling the dice by just lowering you junk!!! Like papaw said grease is cheaper than new part!! Boy grease all those allemites and you better not miss one!!!
