Stalling Evinrude 70 hp

[Richard Eriksson]

Motor: 1985 Evinrude 70 - completely rebuilt beginning of this season.
Has run flawlessly - until today. Started normally, took a 15 minute
ride, docked boat (ran fine). Started back up about 2 hours later,
runs only at idle or minimum throttle - give it more throttle and it
dies. Starts right back up - but dies again whenever more than idle
throttle (in gear) is applied. At idle it is blowing more blue
smoke than normal. This engine was rebuilt (all three cylinders)
and had a new VRO pump installed.

Any quick checks I can make?

When it starts to die, push in on the key and see if that helps it

Richard-

I've got a 1980 Evinrude 70 HP that had the same exact problem- it would run
fine when cold, then sputter and die, or run roughly only at idle when warm.
My marina mechanic went nuts trying to fix it, replacing plugs, cleaning
carb, and adjusting stuff. What FINALLY fixed the problem was a new power
pack (about $350, if I remember right). Good luck.

To all that offered help:

I am an idiot. While greasing the tilt and steering fittings, I
accidently disturbed the gas line connection just enough so it
"unclicked" the latch. There was just enough gas flow to let the
engine run at idle, but whenever I gave it throttle, it was sucking
air. Meanwhile the VRO pump was working just fine, so the engine was
belching blue smoke (too much oil for the gas). Anyway, found the
problem today, ran at fast idle until the plugs unfouled and the
engine now runs fine.

Thanks again for the help.

Join the idiot club. I stopped my boat, and walked around to retrieve the
ski line. Then it wouldn't start. One of my friends towed me to the dock.
As we got there, I took my shirt off to jump in the water to tie it up, and
found the lanyard hanging from my bathing suit. DUH!

Do a spark ck and ensure all the linkage is free and unbroken, also do a
compression test just to be sure.
