Why Your Marine Lower Unit Needs Regular Service
Though your marine motor gets all the attention, your boat isn’t going anywhere without the lower unit. Its combination of gears, bearings and other components turn horsepower into movement. Lower units are resilient and can last for years – provided you service them annually. Here, we reveal the inner workings of a marine lower unit and show the common suffering points.
Our Marine 75W-90 is quite popular. In fact go to OEM products for their engines because they worry about warranty, still come to AMSOIL for this one product because they notice no more water foaming when they drain the fluid. If you see foaming you do need service so don’t expect an oil to correct that but AMSOIL has you covered in case water should get in there.
