My opinion that's not a good ideal. If it's not broken I would keep as is. When you bypass you have to mix the oil yourself at the tank where as you have a reservoir doing it for you. You mix to much you will smoke up the area every where you go. Not enough then you risk again hurting the engine. Just remember every time you gas up you must oil up.I just replaced the water pump and serviced the foot oil, I am taking the boat next week to have the self oiler bypassed, it may sound crazy since it is working at the moment but I’m afraid if it goes out there goes my engine , I get it bypasses for about $250 a lot cheeper than an engine
