thanks in advance guys first post on the site im working on this boat for a friend it has sat for a few years so i rebuilt the carbs and put new primer bulb and line we took it for a drive yesterday it ran decent but is only half power at wot but out of the blue and sometimes when you hit a series of waves BOOM you get max power and it planes out will stay there until you throttle back down then same thing half power and its a wating game till you get power back thought the trottle may be sticking but took the covers off and the butterflies are fully open this has got me stumped havent checked fuel pump yet thanks for any advice.
