I had a 1973 850 which cost em over $600 for a new distubutor when is
started freaking out. Question does your motor do weird things when you turn
the key off. Mine would sputter and spit like it was possesed and it took
the local mechanic a couple weeks and a special merc tester to tell me I
needed and new distubtor. I've switch to a 100 hp Johnson and love it so
far...I can't wait to wakeboard behind it!

Hello all,

I just brought my 1150 Merc 6 cyclinder outboard out of storage. Motor
has
been mechanicaly quiet an ran fine in the fall. It just didn't want to
start
for me this spring. Made a mild clacking sound (one per revolution) like
it
sometimes makes when cold if it hasn't been run for a few weeks. After a
few
aborted starts the clacking sound is gone. Kept playing with it but it
will
not continue to run once started. Replaced all the old fuel and drained
the
bowls, but no change. If I leave it sit for 5 minutes it will start and
idle
for 5 to 6 seconds. If I restrart it immediately it will fire up but quit
right away after a few cylinders fired. It seems to fire up immediately
everytime I turn the key and then abruptly quit after a few cylinders
fired.
If I let it sit a bit it will run for noticably longer before it quits.
Pumping the bulb when it is running doesn't seem to help.

I'm guessing this is fuel related as opposed to spark? I looked at the
fuel pump membrane and it looks fine. I pulled the plugs and they look
fine.
Could it be flooding on a pair of cylinders because of a faulty needle and
seat?

Thanks for your help.
