I lost 2 cylinders in my 150 Vmax due to water ingestion and had to have the motor rebuilt. Yamaha would not cover the engine and I had to go the insurance route. Just got the boat back last week after taking my boat to a 5 star rated Yamaha dealer in the local area. After running the motor a couple of times. I pulled the hood to adjust the shift linkage and found a power head that looks to be remanufactured. The paint on the block is a different color than the original but the motor runs fine. Is this something I should be alarmed about and is there any way to tell if the motor is a reman instead of new...or rebuilt. I would just like to get a few opinions from the experts on this board. Thanks....
