just replaced my trim pump to my 290 outdrive, i have been using penatrating oil on the hydrolic lines all last season and everything came apart easily, i was worried the flair nuts were going to twist the steel piping but everything went well, what type of fluid do i use, the old pump said motor oil or trans fluid, the oil that came out was clear, also my pump does not have a plastic oil container the oil is stored in the pump housing
