First the engine in question has Perma Gap plugs and are not gapable if the ones in the engine are they are the wrong ones. Plug to use will be NGK (preferred) BUHW-2 or Champion L78-V. Type of gear will be preferably Quicksilver premium blend or any other quality LOWER UNIT OIL. Do not use a hypoid 90 or such they do not hav ehte water emulsifiers that lower unit oil have. Good luck and happy boating
