Inboard & Outboard Engine Repair
At Alesta Marine, we provide high-precision inboard and outboard engine repair and diagnostic services for both gasoline and diesel-powered vessels throughout Greater Vancouver and the North Shore. Our approach is defined by engineering rigor, focusing on root-cause analysis and long-term mechanical reliability rather than temporary fixes.
Whether your vessel is powered by a high-torque marine diesel or a high-performance outboard, our mobile engineering unit brings shipyard-level diagnostic tools directly to your marina, minimizing downtime and ensuring your propulsion system meets OEM (Original Equipment Manufacturer) specifications.
Our Specialized Engine & Propulsion Expertise Includes:
Advanced Diagnostics & Troubleshooting: Expert analysis of complex performance issues, including intermittent loss of power, overheating circuits, hard starting, and abnormal harmonic vibrations.
Marine Diesel Specialists: Comprehensive service and top-end repairs for industry-leading brands such as Cummins (6BTA, QSB, QSC, QSM Series), Volvo Penta (TAMD, D-series), MAN, and CAT. We focus on fuel injection timing, cooling system descaling, and turbocharger integrity.
Gasoline Inboard & Sterndrive Excellence: Specialized maintenance for Mercruiser and Volvo Penta gas engines.
Outboard Performance Optimization: Full-spectrum service for Yamaha, Mercury, and Suzuki outboards, including computer-aided diagnostics, gearcase pressure testing, and periodic 100/300-hour maintenance.
Critical Systems Repair: Professional repair and replacement of seawater pumps, heat exchangers, high-pressure fuel lines, and charging systems (alternators/regulators) to ensure offshore reliability.
Why Vancouver Yacht Owners Trust Alesta Marine: Every repair is performed with a commitment to ABYC engineering standards. We don’t just replace parts; we inspect the entire ecosystem—from fuel quality to exhaust backpressure—to ensure your engine operates at peak efficiency in the demanding Pacific Northwest marine environment.
Frequently Asked Questions
Can engine repairs be performed at the marina or dock?
Many inboard and outboard engine repairs and diagnostic services can be completed on-site at marinas or docks, depending on access and the nature of the work. Mobile service helps minimize downtime and keeps your vessel in operation.
How often should marine engines be inspected or serviced?
Service intervals depend on usage, operating conditions, and manufacturer guidelines. Regular inspections and routine servicing help maintain engine reliability and reduce the likelihood of unexpected mechanical issues during the boating season.
What types of inboard and outboard engines do you service?
We service gasoline and diesel inboard and outboard engines used on recreational vessels. Our work focuses on mechanical diagnostics, maintenance, and engine-related drivetrain components such as shafts and propellers, within a defined service scope. For specific engine or drivetrain questions, we recommend contacting us to confirm suitability.
