    Shaft length

    I have a 1970 9.8 hp 110 Mercury outboard . Measuring from the ventilation (cavitation) plate to the top of the transom with the motor vertical it measures 17" ? I thought that standard shaft lengths were 15" , 20" , or 25" ? Is 17" an odd ball? My boat transom is only 15" ? Thanks Tom
