"ok, I have gone thru this forum trying to find bits a pieces to my motor's problems and many have helped greatly.. Last summer the problem started all of a sudden during acceleration under load the motor popped and sputtered like something broke, and would not get up on plane without much backfiring and rough running. The boat still idled perfectly but rough under load. I have since rebuilt the carburator, acceleration pump pumps lots of fuel and carburator seems to perform correctly. New points, distributor cap are new also. This summer I have installed new pertronix electronic ignition, pertronix coil, spark plugs, plug wires, checked all timing marks and timing belt for slippage hoping that this would solve the rough running situation. Upon starting the motor the motor runs rough at idle now and was difficult to get it up to about 2000 rpms with the muffs on. What is the next step to check out? Distributor weights or springs? Timing?Valves broken or something internal? Leak down test? Am stuck at this point until I get the sea water pump carrier from VP I can't run the engine, but any suggestions would be great. thanks"
