Hi, I'm new to this site. have lurked this site on and off for years though. Anyway, I have a 30 hp Tahatsu that I love. But I'm getting scared I'm not going to be able to find a lower unit or a CDI , waterpump when / if they break. I think the motor is an 1983 or so. I can't find a model number on it. All I can find on it are these numbers . On the lower cowl right under the spark plugs it says "Tahatsu Japan 346-67100- , Then on the Transom mount it says 346-62310-, Then there is a side ways number that says 16150. And also keep in mind this is a round prop shaft shear pin motor. Not a spline prop. I can't seem to find an " M 30" number anywhere ? Guru , You have any ideas ?
