    Motor losing prime

    I have a 2001 225EFI. The last 2 trips out I put gas in the boat. When I get to the water my motor cranks then goes dead. I have had to pump the bulb up on both occasions. Any ideas on why it's doing this?

    Air leak somewhere. Tighten all connections on bulb line. Maybe a bad bulb.

    most always you'll need to pump the bulb after stopping for awhile to fish or to move to another location and most certainly before I launched. I know my old 200 EFI was that way.

    See the following post:

    Make sure you've addressed ALL recommended items.... preferably AT THE SAME TIME.

    BTW... get in the habit of pumping the primer bulb firm before EVERY engine start.
