Every time I take my '99 ski centurion D-Drive out to the launch, it takes forever for it to turn over, and a couple of times I ended up flooding it! Is it because it has sat for like 1-2 weeks, or is it the steep angle of the ramp causing it to do something to a gas line? IDK... Anyone with the same or similar boat have this issue? Thereafter, the boat runs good for the day and starts up fast each time.
