I have a 1972 Mercruiser with a 180 cid, 140 hp 4 cyl. engine.
I always have to add gas to the carb before I start the engine after it has been sitting for a day or longer.
What could be the problem and how do I fix it?


Hi, Could be a bad check valve in fuel pump, or choke out of adjustment.

I would also check for suction leaks...... all the way to the pick-up in tank.

Loose clamps, old hoses, or the smallest pinhole(ever so slight) can cause the same problem.

Happy Boating, Wayne


Another Question:

Hi,
I have a gas problem.
When i pump my primer bulb I cannot get anything out of it except air.
I cannot get any gas to pump out or into motor.
thanks!!

My reply:

Have you tried a new Primer bulb or complete hose assembly?

Order one on-line, just click the banner at the top of the page and you'll find most anything you need for your boat and motor at a great price.

You can also get one right in sporting goods department at K-mart and W-mart.

I tell all my customers to keep an extra fuel line-primer bulb assembly in their boat all the time.

Because of the alcohol in todays gas deterioating the check-valves in the primer bulbs, they cause 9 out of 10 fuel related problems.

I'll be adding lots more tips and helpful information in the weeks to come.
In the meanwhile should you have a specific question you need an answer to just E-mail me and I'll do my best to help.
HAPPY BOATING
