Review on New Alternator for Mercruiser 260 MIE GM 5.7L 8Cyl 1987 - Part Numbers: 60050 12449 AC155603 AC155604 AR150 AR150AA AR150AR AR150BA A000B0331 AC155603 39200 3854182 3853853 by John Duffield

Pros: - Great product - Seems to be a solid assembly Cons: - No installation documentation; Lab test results only - the case was about 1/32 inch thick at the top, but could be adjusted with a hammer. Overall it is a great match for the Small Block Chevy 350ci Mercruiser 260 5.7L in the Sea Ray. Some knowledge of the mechanics may require patience and skills when searching the internet. Connect orange to outlet, black ground to "E" on hull, red/purple from your boat to purple, and red from your boat to red on generator.
