Hello I am wondering if anyone can help me? I have an 82 wellcraft 23 nova with a mercruiser 260 or chev small block 350. The rubber around the harmonic balancer wore out and I need to replace the balancer. Mercruiser wants $221.00 for a new one, Autozone wants $49.00. Both have the same diameter 6.75" however the autozone one seems a little thicker and possibly heavier. The Autozone one fits without rubbing anything and they recommend it for the chev 350. My question is can you get away with replacing the mercruiser balancer with an automotive part and does anyone know if the 260 engine is internally balanced?
