I have twin Yamahas when I change oil in the lower gear case can I use the Mercruiser high performance gear oil that I have leftover from my Mercruiser? I have over a gallon. Thanks
It should work fine as long as your Motors aren't some of the large, higher HP units that specify a special lower unit oil....maybe check your manual or Yamaha dealer to be sure.....no need taking any chances....
