good question ,I like to know that my shelf ,I have a 50 hp I though about that too
Just got my hands on a new to me 2007 Yamaha 90hp two stroke that is oil injected. Should I leave it factory or take it off and mix it myself?

I run a 2007 175 hpdi with the oiler and never had any problem. I use the Mercury semi synthetic oil. They are reliable and should cause no problems. I do not like the hassle of mixing oil and gas

Nware14 , my only problem is the warning buzzer doesn’t work , not sure how to check out the problem?
Is it the wiring or the butter ? I was told maybe the reservoir float .

Unhooked mine many years ago on a 150 Johnson. I don't trust the warning system to let you know quick enough. To me what's the difference in pouring oil in the fuel tank or an oil reservoir. When I mix my own I know motor is lubricated. Walmart and parts places carry a jug that holds a quart of oil and is marked in ounces . I will take my chances on me and not a sensor.

I had a '84 70hp Yammy on a 15.5' fiberglass boat, and I ran it like I stole it for most of the 15yrs I owned it ... never a problem with the oil injection system. In fact, the boat gave out long before the motor (according to the guy I sold it to).
I'm currently running a 1999 90hp Merc with oil injection and did run low on oil a few years back ... sensor alarm went off & I idled in & got oil & went on about my business. I now carry a gal jug of oil in the boat, but also check the reservoir every couple of trips. The motor may be a 1999 model, but it doesn't have many hours on it, even though I'm the 3rd owner. With that in mind, I have confidence that the injection system will perform as intended, for many years to come. Well, that and the fact that I locked up a 50hp motor many decades ago, by "thinking" (incorrectly) that the gas in the tank had the appropriate amount of oil mixed in. I just trust the oiling system & alarm system more than I trust my memory or my calculations (when adding gas to a built-in tank).
But, that's just me ... and I do know that a lot of people have removed the oiling system & manually mixed, and been fine with the results. Although, I do seem to remember that many of those folks were running Johnson/Evinrude VRO motors. And even OMC discontinued the VRO system & went to the OMS after so many reports of issues with the VRO system.
