Good afternoon everyone! New to the site and have an issue i could use some help with.

We bought a boat with a blown up motor and put another 200 on it and now when we took it out this morning it feels like we may have a fuel delivery problem. The motor idles great but as soon as you give it any throttle it starts to bog and will eventually shut off. If we push the primer in on the key it will plane and cruise for a little while but then eventually die and you cannot let go of the primer. From what we understand the carbs were just serviced at a reputable dealer.

Any ideas on what it could be?

Thanks guys!
