outboard motors make such stupid claims??and think they are pulling the wool over our eyes!!!! for anyone remotely familiar with these style motors knows.... there is way more different between the different HP models than stupid carbs! they even sell the heads for the 90 hp and the 115 hp and call them interchangeable!!!!!!!!! yeah they BOLT on, but that's it. the combustion chamber between the 90 and 115 hp is about .080" different!!!( the 90 has a deeper chamber).plus the blocks have much different exhaust and intake port configuration!!! you cant use a 115 hp block and slap 90 hp carbs on....well I guess you CAN..... but they are not made to work together. the 90HP and 115 hp motors have different carbs, heads and porting!!!
