History: Installed a SBT motor last year. Break-in went fine. Over the winter I decided to rebuild the carbs.(after reading threads saying it should be done with new engine) After carb rebuild I could not get it started. Removed the plugs and turned it over - got a face full of gas. Read some threads on similar problem and figured it was carb diaphram problem. Put the old diaphrams back in. Engine started right up and ran great - on the trailer. Put it in the water and it would not start.
Today: Started it on the trailer before putting it in water. I got it to start in the water after holding full throttle and cranking the motor for a long time. It took a little throttle to keep it running at idle. After idling for about 5 minutes ( to clear no wake zone), I gave it about some throttle - jumped out of the water and was accelerating for about 10 seconds then just quit. Tried to start - no luck. It sounded like the battery was almost dead. Towed back to dock. Tried to start again - it turned over great but would not start. Put it back on the trailer - started right up. Is this a carb problem or do I have a bigger problem?
