M&M Marine Pre-Sale Inspection & Reconditioning:
Mechanical Inspection:
• Each vessel undergoes a comprehensive inspection by a certified Yamaha or Mercury technician.
• All onboard systems (switches, lights, pumps, stereo, speakers, MFDs, and transducers) are tested and repaired, or replaced, as necessary.
• Engines receive full servicing in accordance with the latest manufacturer-recommended intervals.
• Customers receive engine diagnostic downloads and compression test results.
Cosmetic Reconditioning:
• Hull sides and topsides are compounded and polished to remove any gel coat scratches or blemishes.
• Bottoms are repainted with SeaHawk Monterey bottom paint.
• All through-hull and underwater hardware is cleaned and polished. Trim tabs are dropped from the actuators, cleaned, and reinstalled with new hardware.
• Interiors are deep-cleaned and polished.
• Each vessel undergoes a final, detailed cleaning before customer pickup or delivery.
• Some cosmetic wear is to be expected on the powder-coated feet of leaning posts and hardtops, as well as on stainless steel rub rail inserts.
• Our goal is to present vessels as close to "like-new" as possible, considering up to three seasons of use and as many as 800 engine hours.
