Hey guys. Just purchased a 2004 launch ssv about a week ago. The boat is in mint condition with about 250 hrs. Took the boat out for the first time this past weekend. It ran and operated perfectly until I got down to about a 1/4 tank of gas. It would start bogging down while cruising around 20 to 25 mph. If i backed of the throttle, it would do perfect. Get back up to speed and it would start to bog again after about 10 to 20 seconds. So i put about 10 gallons in at the marina. After that, we road around for about another hour or so with no issues. Has anybody experienced anything like this? Any help would be awesome. Thanks
