Water in the fuel line?

[Tricky]

My boat seems to be getting water in the fuel line somehow because she
runs a little rough for about a 1/2 an hour when I 1st start her up and
then she purrs like usual for the rest of the day? I think the tank is getting
condensation perhaps? Any thoughts or suggestions as to what it could be
and how to fix this? It's a 1986 4.3 liter Mercruiser I/O.

Try some Sea Foam Motor Treatment for Small Engine Applications. It can be purchased at any NAPA store. I’ve included the Sea Foam website.

It Stabilizes fuel, Cleans carburetor, Cleans carbon, Removes moisture, Assures fast starts, Frees sticky rings, Restores power, Upper cylinder lube, Smooths rough idle

You should install a water seperating filter on your boat. With todays high Ethonal content and more in years to come there will be more problems with moisture in gas. The seperator will help and once it is installed just chage the filter on it once a year. Mercury price is $97.95 but you can get a NAPA one for about $60. It is the same filter on the old Chevy block.

Hope this helps

SeaFoam sounds like this product I used a while back...

JP how do you install these things. Do they go onto the fuel line that leads to the carb? Is there instructions that come with these filters?

FT, who is CTC and what does a remote one mean?

[Andy_L]

CTC usually refers to Canadian Tire Corporation

Mount it between the gas tank and the engine. You need to maout it to any flat verticle surface.
the gas line from the tank goes in one side and another gas line goes out to the engine on the other side of the filter. There is an arrow to show you which side is which.

They are very easy to understand and once you see it you will understand.

Let me know if you need help.

Thank Guys... I went to CTC but they only had 1 that looked more like an
oil filter? So I don't think that's the one I need... guess I'll be going to the
NAPA guys, do they need any specs on my engine? If I tell them it's a
1986 4.3 liter Mercruiser I/O is that enough info?

Thanks again for everyone's help!

[JP]

The filter does look like an oil filter but you need the whole assembly and just tell NAPA that you need a water seperating filter assembly for a 4.3L Chev marine block.

Do they have them for regular outboard 40hp Mariner. If so are they inline?

[JP]

They can be added to any outboard or inboard engine as long as you can install it on a flat verticle surface between the tank and the engine.
