Hi folks - does anyone have any top and side photos of the 40 and 50 yamaha tuners? Are the 15 inch and 20 inch versions identical? any dimensional info on the i.d./ inside area and lengths stock vs what length/area you're running for your rpm range? Also has anyone tried the older 3 cyl omc carbs on one of these motors or know if they are a close fit?

thanks,

ccaiken
