Boat Technicians Santa Barbara — Mobile Marine Diesel Service You Can Trust
Keep your vessel running strong with 805 Marine Mechanic, your local team for mobile, dockside
marine diesel service across Santa Barbara, Ventura, and the Channel Islands. From proactive care to precision repairs, our technicians help you prevent downtime and protect your investment.
Preventative Maintenance That Pays Off
Preventative care catches small issues before they become big bills. Our mobile technicians perform
routine inspections, fluid and filter service, and system checks tailored to local conditions.
Supported brands include Cummins, Volvo Penta, Yanmar, Caterpillar, Beta Marine, Scania, FPT, MTU, Ford Lehman, Perkins and more.
- Engine Tune-Ups: Optimize starting, idle, and load performance. Tune-ups help spot developing problems and keep fuel burn in check.
- Hull Cleaning: Remove growth to restore speed and efficiency. Pair with
engine-room refinishing for better visibility and easier leak detection. - Propeller Care: Inspect for dings, bends, and pitting. Proper pitch and a clean edge maintain speed and steering authority.
Consider seasonal prop pulls and shaft alignment verification.

Smart Diesel Care: What Owners Should Watch
- Oil & Filters: Check level/condition and change by hours or annually per engine manual.
- Fuel Quality: Replace primary/secondary filters at interval or when contamination is noted.
- Belts & Hoses: Inspect tension, glazing, cracks, softness, and clamp security.
- Cleanliness: Keep machinery free of salt and oil film to avoid heat soak and corrosion.
- Temperature Monitoring: Rising temps may point to a bad thermostat, low coolant, or worn seawater impeller.
- Seasonal Care: In colder climates, winterize to prevent freeze damage; in SoCal, schedule “lay-up” checks for extended idle periods.
Don’t Ignore the Exhaust Mixing Elbow
The seawater/mixing elbow at the riser is a known choke point. Rust and scale reduce flow and can back-flood cylinders.
Many makers recommend seasonal inspection: remove the cooling hose at the elbow and assess for restriction.
If passage is narrowed, pull the riser for cleaning or replacement. Review your
maintenance schedule
and parts guidance.
