Best prices and fast delivery

Excellent price and excellent service. Unit arrived ahead of schedule. Much appreciated the excellent service.

It was a hard-to-find item that Boatplicity had in stock and at a decent price. I will be back for more stuff for my boat.

The only thing that didn't go very well was the time it took to receive the 2nd part of my order. I paid extra for 2 day shipping. It took closer to 6 days to receive my CDI switch box.

It was exactly what we wanted. Excellent product.

A+

Love it fast and easy.
