Not sure how important it is but my 40EFI recommends 80W-90 Merc Lower unit oil....The 80W-90 bottle actually says for 75 HP and below and the 90 weight for 75 and above
80W-90 Premium Gear Lube should only be used in engines with a horsepower rating below of 75hp. SAE 90 High Performance Gear Lube should be used in engines with a horsepower rating of 75hp and above, but can also be used in the 75hp and below applications as well.
Good job, explanation of lower oil change will be easy to follow. Thx for keeping it simple!
Thanks, Very professional
Great video, thanks!
