Our Clients

Aleix Font
Excellent service. I am very satisfied with the attention received from Milton and Alejandro, as well as from the official mechanics. Without a doubt, if you have a Mercury engine, this is the best place to take it. I was kept informed at all times about which parts should be replaced and how the repair was progressing. Most importantly, the final decision was always left to me, with no attempt to make me spend unnecessarily. Very professional, thorough and transparent.

Their comprehensive maintenance service is truly appreciated: mechanics, upholstery, electronics, stainless steel work and more. A single point of contact for everything your vessel needs. Thank you, Heavy Seas.
