Hi Jeff,
Sorry to hear about the outboard problems, first thing I would try is
to open your gas cap and see if air rushes in or if it improves your
motor's performance. A plugged or partially plugged gas cap vent
could cause the symptoms you are describing. Next, check the fuel
filter as you described. Try a new spark plug, or at least look at
the condition of your spark plug, that could give you some indication
as to what the problem might be. Lastly try fresh gas with a carb
cleaner like sea foam in it, sometimes that will be just enough to
take care of the problem. Good luck, I am sure you will get it
worked out. --Chad

Help!
I bought a brand new Nissan 4HP 4-stroke motor last year and it
was very nice. Quiet. Started on the second pull every time. It has
probably no more than 10 hours on it at this time as i use it
mostly for ramp purposes. Up until last weekend it has been running
perfectly.
Last weekend, though, i could not start it at the ramp. Not a
sputter... not a single sign of life. We had to test our sailing
skills and get out of the harbor under sail. Good practice but not
something i wanted to do again. The next day i went to play with it
to see if i could figure out what the problem was (right! I know
outboards like Kobe Bryant knows humility). When i went to start it
up on the trailer it cranked up on the second pull just like
normal. I had no water hooked up to it so i let it go only a couple
seconds and shrugged off our experience to some sort of anomoly.
Based on that succcess we went out again yesterday (Lake Pardee
for those of you in norCal... fishing lake, no waterskiers
allowed... lake level 98% of capacity and very clean). I went to
start it up and it started as expected, but....
When i pushed the choke back in upon warm-up it proceeded to
die... i pulled the choke back out to ensure that she would keep
running ... perhaps she needed to warm up a bit more... pushed the
choke back in and she died and would not start again. Showed no
sign of life...
My novice thought is... fuel filter? Water in the line? I don't
know how that could happen but i suppose it could. I will attempt
to replace that myself if that is a probable cause but i thought i
would throw it at this group first as you folks are dialed on all
aspects of the Monty Life!!!
Thanks for your help,
Jeff
