How many cylinders is it? If it's a 6 Cylinder, then it's this one.<br /><br />1150 (115HP) 3270480 - 3525440 1972 6 cyl inline<br /><br />Or:<br /><br />1500 (150HP) 3502806 - 3752619 1973 6 cyl inline

Since it has the 150 and 1500 on it. I can only assume it's the 150 HP Model. It's sure not a "Model" 150 with an inline 6 cylinder. Best I can do for now.

Thanks Rick for your help, its more than i knew.<br />O the 150 is on the shaft as it starts down to lower unit.
