1998 90 HP 60 degree (model # J90SLECM)
I just rebuilt the entire motor 100 hours ago.
My motor has been running a bit bad lately, not wanting to idle in gear, hard starting etc.. I was told it was more than likely an ethanol problem. I put 3 oz of sta-bil ethanol treatment in the gas (30 gal tank). This seemed to make it worse.
Yesterday I left the dock, and it was a little hard to start, but nothing out of the ordinary. I ran probably 5 miles both no-wake and cruise speeds. I shut it down at the sandbar, started back up after about an hour. It was even harder to start this time. As soon as I put it in gear it dies. Finally got it running and shut it down after about a mile while we fished under a bridge. I could NOT get it running again worth a crap.. Smoking horribly, shaking etc. The only way to make it run was with the throttle at 75% , out of gear and it turned about 2000 to 2500 RPM , that is it!
I checked the water separator, and it was clean. Pumped primer to see if it would smooth out, nothing.
I noticed a “substance” inside the carbs that was a milky/blue color, there’s no water in my oil tank, no water in the fuel separator. (yes the VRO is still hooked up).
I noticed that one of the little rubber hoses behind the starter had popped off and was spraying gas out. The top one on the port side of the block, (not the enriching/choke line) . I put it back on and the problem persisted.
I managed to start it in gear, (2000-2500 rpm) and limped to the nearest ramp. Could not get any more rpm than 2500 and no less than 2000 (w/o it shutting off), leaving a nice blue smoke trail behind me..
WTF??? Any advice??
