I read a post that said that the late '80 and early '90 vro runs @ 1:100 @ idle. And that Evinrude changed this back to 1:50 on their later models.<br /><br />now I have '88 120HP 'Rude(BE120TLCCA, G1738847) And I found these numbers on the back of the pump(the part that looks like a flat horn) 174619 MX and 11 EN this is engraved in the alu/steel.<br /><br />And then there is in ink on top of the plastic part were the oil enters the system: 1238.<br /><br />Now is this pump a good one or should I update.
the engine runs great. But I'd like to keep it that way... THX for your time.
