My boat has a Yamaha 150 V6 Salt Water Series outboard. It is not the original engine on the boat and the decal on the transom mount is curled up from a cable rubbing on it and is unreadable. I am not able contact the previous owner and can't remember if ever even told me the year of the engine. It is in almost perfect shape and I never had any problems with it. Now I need a starter and some other parts and need to know the year of the engine. The cowling only says Salt Water Series 150 V6. No model number. I have looked all over the power head and can't find any numbers except torque readings. It's like new so if it is more than a five years old I'd be surprised. It's not a salt water series II, It has carbs, not fuel injected. What years did they make Salt Water Series 150's? Any help would be greatly appreciated.
