1996 Yamaha S175hp salt water series Mod# TXRU<br />6G5 UL S/N 500427.<br />My factory manual calls for oil pump adjustment to be all the way to the stop (touching it as I interpret) is that correct? it has about .035 to .040 gap on it now. The problem I believe stems from slow trolling bumping in in and out 1 to 2 kts (its King season here) I use ring free @ the 1% ratio on every tank. On my last trip out I lost lots of power, found 1 fouled plug. Replaced plugs with OEM spec plugs gapped IAW (In accordance with)specs, same as I took out. <br />The big question is should I adjust the oil pump linkage as the book says to "0.OO" ? or should I leave a .02 to .05 setting. Will it still get oil fully closed? does it have a built in bleed amount? or is my publication in error?
