Default Trouble shooting Mercury 1882 150 V-6

Well, haven't gotten it out on the water, but I did find two or three
possible problems.

I'm not certain that there was water in the fuel, but the boat HAD the old
style open vents, and that boat takes a pretty big wave over the back deck
if I come off plane to quickly. I replaced one vent so far with a new style
vent that is not supposed to take in water unless you forced it in under
pressure. I'll replace the vent on the other tank if I have time tommorrow.

I added a Racor 2 micron filter and water seperator. Just in priming the
filter witrh the prime pump I noticed a little garbage in the bowl.

I tore down the fuel pump because a couple times it just sounded like it was
running out of gas. I couldn't find any pinholes in the diaphram. Not even
holding it up directly to the son. I did find somethign interesting though.
The diagram return plunger was just floating around in the valve chamber of
the pump. The spirng that pushes it out to push back the diaphram was
missing and the plunger could easily have been obstructing the flow through
one of the valves since the spring is supposed to hold it in place. I
ordered a spring from Alsco Marine along with a couple other parts for the
cowling. In the mean time I put the pump back together with out it. It
pumps gas just fine so tommorrow.

Ok, now for the driveway test. I ran it up to 4000 RPM in the driveway and
it nevered reved like it was running out of gas, and it never died or
spluttered. I ran it for a couple minutes at 1000, 2000, 3000, and 4000
rpm. It seemed to run great. I know that isn't the same as running under
load, but it didn't run well even at 3000 rpm before.

I might have some time to take it out and run it tommorrow afternoon if that
storm that's coming in tonight blows through.

Heck, my dad probably has a half dozen gas cans I could have borrowed, but
I'm a do it now kinda guy and he lives 70miles away. Hell, he has a

couple
motors I could probably borrow.

Besides I'm gonna want to have a couple 6 gallon tanks anyway when I get
around to putting my 50HP force on my little skiff.

Oh, you meant THOSE kind of friends. No I like all my friends better than
that. LOL

I stopped by the local parts shop to get a gas can, and we got to

talking
about the symptoms. I think I may just have a pinhole getting bigger

in
my
fuel pump diaphram. The rebuild kit is less than $10 so I went ahead

and
ordered one. Should be here in a couple days. Its real easy to check

too.
I can try it with an electric pump temporarily and see what happens.

I'll keep you guys posted. Thanks for all the help.
