My motor wouldnt turn over as I posted the other day on my mercruiser 170 with pre alpha outdrive. I pulled the out drive,she fired up with barely bumping the key...made me happy and sad. I couldnt spin the spline coming out of the out drive and before pulling it checked the oil level which was nothing....I had bought this as my first boat the day before I took it out and it locked up on me in a matter of minutes. Well i figured i'de seperate the upper and lower and see which one would turn diagnosing the other half as the problem but couln't seperate them so I pulled the cap off the top of the outdrive and the cone shaped bearing at the very top that rides inside the cap was chewed up someand with the cap off it freed up the whole outdrive...it even turns with the cap on now but theres some metal filins along the inside walls so it needs to be cleaned and the bearing replaced....how do i get this bearing off or am i better to just let a mechanic service this becusase flushing it out shoulnt be too much, right? And where can i find these parts on the internet?
