twin won't run

[Paul Kneisl]

I had an outboard motor that did something similiar. Started and ran preemo at the dock. Get 2 or three miles away...stalls...then started and ran when coola little, but soon quits. Ignition coil was removed by dealer and the clamp holding it on was overtightened, squeezing the case and making it so when motor heated up, it lost the coil function. Worth a shot.
