Re: C-Drive Oil drain - Alternative

Craig Briggs

Hi Porter et al,
There is no "circulating system" in the "C" drive like an engine has with an oil pump and channels and holes for for pressurized oil flow. It's just a hollow structure around the gears and bearings that creates a bath of oil. The hoses at the top simply allow for expansion into the reservoir as the oil warms slightly and, while there may be minor circulation of oil due to convection, that's just incidental. Pretty much analogous to the lower unit of a 2-cycle outboard...
