Serpentine Belt Replacement

[mjr119]

Does anyone know the part number for the serpentine belt on a 2003 LSV with an Indmar Assault MPI? I want to swing by napa on the way home to get a new belt.

I noticed a slight squeal from the belt when I had the boat out yesterday. Is it difficult to swap? Or same as any other belt? Does it have a tensioner pulley?

I can't recal off hand but most Serpentine belts have a tensioner like cars. You can always remove the belt take it in, they can use a measuring device and match it up.

Odds are that it was you alternator belt which is separate. If the battery voltage was pretty low it was loading the alternator hard causing the belt to slip. Make sure that you get one of those too.

I bought a new battery last night. I was getting between 12 and 13 volts when running.

Should be a solid 13.5 to 14 when running. You can check voltage when revved up to 2K as this is when an Alternator puts out max voltage.

I think my alternator is on its way out. I'm getting 13 max.
