Bought a 2009 EFI Yamaha 4 stroke 40 horse this spring. Live in Michigan. I would like to winterize it my self and am a little confused by the directions. Any place to get easy to understand step by step directions?
easiest way is after changing the engine oil and adding crankcase stor-n-start is to follow the fuel premix solution for the EFI mercruisers and Volvos.
same setup just the parts are oriented differently.
