I have 1983 Johnson 200 hp pushing a 20' Center Console Proline. I just bought it, and it sat since last Aug, but was winterized according to the seller. I replaced the lower fuel pump, ran better at idle. Went to replace the filter on the TOP pump, (pump looked new) and it had no gasket! Replaced screen and gasket, ran MUCH better at idle, when at home on the ears. Starts a little rough in the lake, and doesn't idle that long, (at home, I have to shut it off, it runs forever). I am also only getting about 4100 RPM's, which I know could be a few things, but.... I do not have a fuel/water seperator running from my 25 (I think) gallon tank under the Center Console, should I install one? If so, where?<br /><br />Thanks a million.
