The local Suzuki dealer has rebuilt the carbs, changed the fuel line, adjusted and readjusted the carbs, new plugs twice, ran all Suzuki diagnostics again and again, and every time it leave the shop (three) is was "running like a swiss watch." But it doesn't...<br /><br />She always starts right up, no problems getting out of the no wake zone 1200 RPM(5 mins). No problem getting up on plane. However, 25-40 mins into 3/4 throttle, when entering another no wake zone the idle will be very rough, 1k-800. If i give it gas, it will die, but always restart right away. If I message the thriottle, it will hesitate, get back up on plane, but not have nearly the same power or responsivenes. There will be a noticable hollow sound coming from the engine, and the engine will vibrate a little as it strains.<br /><br />Once throttling back down to no wake, I will not be able to give the boat power beyound idle; I limp back to the dock. There will be oil running from under the cowling down the front of the lower unit. It appears as though it may have come out with some force as it looks to have sprayed out some around where the steering arm enters thru the cowling. One mechanic suggested the lower crankcase seal may be shot thus affecting the fuel pump...but another said no.<br /><br />I have lost faith in the Suzuki mechanic. Any suggestions here would be greatly appreciated.
