Range of years that would work for a parts engine

[IL Landowner]

Can anyone tell me what range of years, and/or horsepower engines would be good for a parts engine? I have a 1974 mercury 150 h.p. inline-6. my serial number is 3913808. I need distributor parts now, but if going to try to find a parts engine would like for the majority of parts to be interchangable.

73-78 is essentially the same motor. Either in 79 or 80 (forgot which) these switched to ADI boxes like the v-6's and carb's were changed around the same time too.<br />Pistons and block are different for the 1500's and '78 1400 in that they have a "power port" that he 1150 and 900 don't have. All other parts are the same or at least will work in the case of carbs.<br />Lower units from any year 73 and up will work (except XS). I dunno bout earlier.<br />Around here I've found some complete parts motor for $300 or less.

1979 is when they went to ADI. 78 was the last year for the distributer motors.<br /><br />Craig
