Stupid question?

[Gary Graycar]

I know the Merc 3.0 is a GM engine. But I cannot place what a 3.0 GM engine powered. We all know what the 5.0 and 5.7 is, but what is the 3.0? I see it is in the same family as the old 2.5. The only 2.5 I can remember was the old Pontiac Iron Duke. Thanks.

Re: Stupid question?

The engines were used in the Chevy II from inception around 1962 till early 70s.<br />There was a 151 CI and a 181 CI.<br />I had one in a 1972 boat, 19'. It did about 40 MPH WOT and pulled skiers at 3400 (28 MPH).<br />They are dependable. think about it, the engine was designed in '62 and still being used by mercruiser.<br />Over 40 years, they would have gotten it right by now.....<br />Captharv

These old iron 3.0 were more of a industrial use type motor, they could be found in tow motors and tractor type equipment also, due to there reliability and low end grunt.
