This product data sheet is originally written in English. This motor leaned out in the bottom port cylinder. The top of the piston melted and deposited some aluminum splash in the combustion area. I checked and it comes right off with no penetration or degradation of the area. I left the remaining in interest of full disclosure. There is no damage to any of the adjacent mating surfaces. It’s presented just as removed from the donor engine. Suitable for 200 and 225 HP Optimax Motors. Donor Motor Serial Number 0T736180. Message with your Model number if you are unsure or have questions. NOTE: The Temperature Sensor is included as pictured but operation has not been verified.
