## Customer Reviews

### ⭐⭐⭐⭐⭐ it was easily replaced with hand tools on the boat
*by D***B on August 29, 2017*

Only even remotely tricky bit was pulling the old pulley off to put on the new alt... was an exact match for the one I replaced on my 01 Mastercraft Prostar 205, three wires, two bolts and a belt... other than the pulley, it was easily replaced with hand tools on the boat.

### ⭐⭐⭐⭐ OEM
*by R***M on June 10, 2021*

Always good to go with an OEM product.

### ⭐⭐⭐⭐⭐ Nice replacement for my boat
*by D***H on May 22, 2020*

I have a 1992 Mastercraft Maristar 240. I replaced the original alternator with this one. It appears to be working as a good replacement product.
