Discolored Engine Oil. I bought the motor brand new in early 2017, live in Wisconsin. I used it every other weekend during the fishing season of 2017. Changed engine oil in the fall of 2017, no problems. Used it again, every other weekend, the fishing season of 2018. That fall when I changed the engine oil, it came out a tan color. Spring of 2019, before the fishing season started, took it in to the local Mercury authorized service center. They could find nothing wrong and didn’t do any service. Used again every other weekend the fishing season of 2019, when I changed engine oil last fall, same thing happened (see pictures). Taking it in again this weekend, before fishing season starts, to the same service center. Welcome any thoughts on what could be the problems? Thanks
