I have a 50 hp yamaha engine. Is it necessary to use only there oil for the motor.
Thank you
I just got my 1st 4 stoke outboard. A 5 horse Merc. It only uses 10 oz. so 3 changes to a qt. that is only `10 bucks. I kow one thing, I dont have to change it very often. It came out pretty clear after 50 hrs. . I am still so cheap that I am going to look at Fleet Farm & Walmart and when I find it for even cheaper , I will buy some. As for spark plugs, how often you guys change them? I have a1997 25 horse Merc. I dont think I have changed those plugs 5 times. I have 94 hrs on my 5 horse . I bought an hour meter as soon as it was new. I wonder if I should change the plug for a whole $2.57. It trolls for hours without a hickup , but it seems to start hard sometimes if I dont run it for 1/2 hr. or so. Needs choke.
I am assuming you have a two stroke that either requires you to mix the oil and gas or the motor has oil injection. If that is the case you should be able to use any name brand oil that meets or exceeds your motors requirements. I would shy away from off brand economy oils as they may not meet your motors requirements. Oil isn’t a place to try and save a buck, just like running ethanol fuel in your outboard to save a few dollars
Absolutely not required to use Yamaha brand oil. Call any marine mechanic, anywhere....ask the same question. Personally, I use Mercury Quicksilver brand oil - I buy it by the case when it's on sale at Menards. Never had any issues, no matter what brand of engine.
