Hull flexing on 47 Lightnings...
 

Hi guys, I service a 1998 47 Lightning and get to run it from time to time. The console in the cabin is shaking like hell when I look in thorugh the cabin door while running. Is this normal?? I know Fountain made a "new" 47 Lightning in late 2005 and onwards. How is that one in comparison? The boat has now 525s. Had Volvo 415s when new in 1998.

Any experiences with this problem? What model year do you have??

Thanks,
Erik
