This is a 2000 Johnson 200 J200VXSS. Had the low oil alarm going off(alarm sound every other second). Replaced the fuel/oil pump with a used one from a 97' Johnson/Evinrude V6 200....last weekend. Cranked and ran fine with no alarm, I don't remember excess smoke. Engine normally would smoke at cold start up, then smoke a little after that....normal. Yesterday, it was a little hard to start(not normal), and smoked 10X more than normal and did not decrease at all, got worse if anything, no alarm. Could there be a problem with this application ? Issue with the "ratio" of oil ? I really don't want to buy a new fuel/oil pump but......... any advise ?
