FAQ:
Q: Where is the power steering belt on a MerCruiser?
A: Drive belts on the MerCruiser engine run all of the components at the front of the engine, including the power steering pump, alternator, seawater pump pulley and circulating pump. The belt must be in pristine condition so that it does not slip or chatter.
Q: How do I know if my serpentine belt needs to be replaced?
A: Wipe the entire inner surface of the serpentine belt with a clean rag and examine it for cracks and frayed fiber. You may wish to replace if it looks badly worn or glazed. Loosen the 5/8-inch locking nut on the pulley adjustment stud with an end wrench.
Q: What kind of idler pulley does a Mercruiser have?
A: Some MerCruisers have dual idler pulleys. You will need the one with the 5/8-inch locking nut and the 5/16 adjusting stud. It should be the top idler pulley with a dual arrangement. Wipe the entire inner surface of the serpentine belt with a clean rag and examine it for cracks and frayed fiber.
Q: How do you adjust a belt tensioner?
A: Turn the 5/16 adjusting stud until the belt begins to tighten. Measure the deflection of the belt at its longest travel length between pulleys. Push your thumb lightly against the belt and measure the movement with a ruler. You should have no more than 1/4 inch, or 6 mm deflection. Take a more accurate reading with a belt tensioner gauge.
