Get yourself an aerosol can of Sea Foam...at any auto parts store. Get a helper to run the helm. Remove the engine cowl and try the hole shot (pedal to the metal) without spraying into the carbs. Get a data point. Spray a squirt into each carb and immediately hit it again. If it roars at you, you have a fuel problem, usually caused by the low speed jets being turned in too far.
But on the water your engine needs fuel to burn to develop the HP that it doesn't need on muffs in the driveway. Fuel means clean fuel delivery lines, fuel pump diaphragm that works properly, inline filters that aren't clogged with old fuel fungus stuff, carbs clean and all that. Sometimes grasping the squeeze bulb and giving it a squirt will help to determine fuel supply problems...associated with the above areas. Bulb should be soft when running, not hard ( carbs not allowing fuel in...float level), or sucked in flat...blockage between tank and bulb.
On later engines the serv. manual says open slightly (some say a screwdriver blade width, others 1/16", others 1/8") all simultaneously, until the engine will take the hole shot without stumbling.....course trim and boat loading and all kinds of other "stuff" could be your problem......but mayb

Thank you so much for the suggestion it seems to me that the bulb stays medium not soft the tank is a new built in aluminum port side fill the other thing that seemed strange to me is the control handle has to be pushed what seems like hyper past what you would think WOT would be im gonna try your suggestions and will post back on the results again thank you for your reply.
