The guide we have provided shows you where to find your boat engine serial number for Yamaha Outboards, Mercury Outboards, Volvo Penta SternDrive and MerCruiser SternDrive. For the exact appearance and location on your engine, please see the operators manual. It can be found on decals and product plates. If it was reported to Yam dealer they might know it.The engine serial number (ESN) is a unique identifier of your product and the key to efficient servicing and correct ordering of parts. Take the serial number to Yam dealer and see what they can tell you about the engine. That is if you are buying a boat that saves money on engines buying Yams NOS.(new old stock)īut what Chief said might be a shot.

This is you could be buying a 6yr old engine coming out the box that needs a water pump before its even started. The seller was the original owner and they were the engines that came on the boat new. Kind of confusing? Years back I surveyed an 08 28ft SeaFox with 01 225 Yams on it. But they still leave the date built sticker on them. Back in 05 or 06 Yam took the letter in the model number out that tells you what year the engine was built, but they sell them as new engines. Yam still has engines built 6-9yrs back sitting warehouses that they sell to boat manufactures as new engines. If the engine was stolen and reported to them as soon as someone using that serial number to buy the part for it they will know it's a hot engine. Merc constantly changes there engines throughout each year and to buy a part fro a Merc engine from a dealer you have to have the serial number. Now I know Merc has this in their system. Right and it should be the job of LEO's to report stolen outboard serial numbers to an dealer of that outboard. There is a 2014 70hp that has a very close KW power rating according to NADA that is also a 4 cylinder motor, but according to everything I have read, the manufacturer date now determines the model year.Ĭlick to expand.

The guy said it is a 80 HP, but yamaha does not make an 80HP.Ģ013 yamaha motors for the 60 and 70hp range are 3 cylinder motors but this is a 4 cylinder.Īnother plate says that it is a max power rating of 50KW. I also want to see exactly what motor it is. There are no signs of the plate being pryed off of the motor either. I don't have any reason to think it is but with the plate missing it makes me wonder.

My first and foremost is that I want to make sure that the motor is not stolen. The engine is clean, guy has the title for everything else but he is the second owner of the motor. The cowling does not have any horsepower numbers on it either. I am looking at a boat/motor and trailer but the motor does not have the identification label plate on it.
