Where is the engine number on a Yamaha outboard? The hull identification number (HIN), which is a label permanently affixed to the boat, contains the information with the boats model year and includes a date assigned by the builder. Frequently, this plate is also marked with the engines year.įortunately, its fairly easy to determine your boats build date (see HINs By The Numbers below). Your serial number, also known as the model number, can be found on the engines midsection. L = 20, P = PT & E start Control, B = 2nd motor change, X = 25, E = Electric start, H = Tiller Handle, C = 3rd motor change, U = 30, M = Manual start, etc. What do the letters mean on Yamaha outboards? The last two digits of the year the outboard was manufactured are displayed as a 2-digit number in a box on the newest serial number labels, which are located in the labels lower right corner.
