Minor Marine Electrical
Routine electrical maintenance and the faults that come with it: corroded terminals and connections, batteries and charging systems, navigation and cabin lighting, blown fuses and tripped breakers, failed switches, and accessory circuits that work intermittently or not at all.

MerCruiser Diagnostics
Rough running, hard starting, overheating, or an alarm no one has traced yet. Precision Marine diagnoses MerCruiser systems and handles many repairs directly, and will tell you plainly when a job calls for someone else.

Volvo Penta Diagnostics
The same approach for Volvo Penta systems: work through the symptoms, test what's testable, and take on the repair when it's within scope.

Marine Upholstery
Cracked, faded, or torn seating and cushions. Repair and replacement using materials built for sun, water, and regular use.
Diagnostics
Not every problem announces itself. An alarm with no obvious cause, rough running that comes and goes, overheating that only shows up under load — these take working through rather than guessing at.
Precision Marine runs diagnostics on MerCruiser and Volvo Penta systems: work through the symptoms, test what can be tested, and narrow it down to an actual cause instead of a list of possibilities.
Many repairs get handled directly. When a job calls for someone else, you'll hear that plainly rather than after the fact.
