Hi I am not sure of the year all these numbers are on the plate.Its a 3.5 HP Spirit<br /> 0351 and 004112<br />then on a sticker theres this number 35002.<br />I am pretty sure this motor doesn't cool the engine as it operates but does it have what they call a wet leg? That is is there a water pump in the lower unit area that cools the exhaust leg of the engine? If so does this operate when prop is turning or when the engine is running? And who has parts?<br />steve
