I bought a boat with 3 Yamaha 350s powering it. The starboard outboard lower center cowling has come apart three times. I keep buying a new part and installing it but again it is coming apart. I called yamaha and they said because it is installed on a jack plate that changes the way the water goes by the engine and it will break the cowling off. They suggested maybe buying another one and siliconing it on. The other 2 engines don't have this problem. Yamahas reponse seems absurd saying their engine will break apart if installed on a jack plate. Can someone help me with this problem. Thanks

Sounds pretty darn nuts to me....maybe call and write Yamaha customer service for repairs, etc.....

you might mention which cowling you are speaking about, or throw a pic up of what is breaking
