looking at putting air on my 51 merc. with the 351 engine in it I am challenged for space. I can only fit a 2 grove pulley on the crank and I will need to run the water pump, the power steering pump the alternator and the air conditioning compressor. thought about running the power steering and water pump on one belt the AC compressor on the other crank belt and adding and running the alternator off the water pump. am I crazy or would this work?
