For outboard engine repair and re-powering in San Diego, San Diego Marine operating from 6996 Mission Gorge Road in Grantville, where owner Sydney runs a repair, replacement, and re-powering shop serving boat owners across the 92120 ZIP and greater San Diego County. The company brings 20 years of marine mechanical experience to outboard service, with core work focused on engine replacement and re-powering — swapping aging or underpowered outboards for new or remanufactured units from Honda, Mercury, and Evinrude E-TEC in configurations ranging from 15 horsepower to 250 horsepower. Fiberglass hull repair and Awlgrip refinishing share techniques with automotive body restoration, and collision repair shops in the same Grantville trade corridor handle comparable paint and body work — Smart Auto Sports - Collision Repair & Vinyl Wraps in Grantville runs spray booth and color-matching operations that parallel the marine finishing process. Annual service covers lower-unit gear oil changes, impeller replacement, spark plug and fuel filter swaps, anode inspection, and compression testing across all cylinder counts. Electronics installation includes GPS chartplotters, fishfinders, VHF radios, and trolling motor wiring — helm upgrades that require clean cable routing and NMEA 2000 network integration on modern outboard-powered boats. Pre-purchase inspections for used boat buyers cover compression checks, lower-unit backlash measurement, tilt-and-trim function testing, and visual assessment of transom integrity and rigging condition. The Mission Gorge Road shop sits within the auto and marine trade corridor that runs from the I-8 interchange toward Mission Trails Regional Park, and the facility accommodates trailered boats up to center-console and bay-boat sizes. Glass and windshield work on marine vessels coordinates with area glazing specialists, and AMB Auto Glass and Window Tint in Grantville handles the tempered and laminated glass fabrication that marine windshield replacement requires. Bottom paint application for anti-fouling protection rounds out the shop's service list for San Diego boat owners who keep vessels in saltwater slips at Mission Bay, Shelter Island, or the Chula Vista marina.
