I have a 1984 2.5 L OMC sterndrive. Model # 252STHRCRA. I am having trouble finding the correct oil filter. The filter that I have on there now is a Johnson Evinrude 502902. The local marine dealer does not sell Johnson Evinrude filters or oil anymore. They gave me a Mercruiser oil filter 35-866340K01. On the box it does say it is for a inline GM 4 cylinder engine which is what I have. However the old Johnson filter is much longer than the Merc. Do I need to to find something else? Also the oil they sold me is Mercury 25W-40. The engine calls for SAE 30 but they told me I should use the 25W-40. Is that correct?
Thanks
