Marine Engine & Service Repair


Make an appointment for an MER tech to come to your vessel for a complete inspection of your power generation needs.

Oil Analysis & SCOR condition based maintenance

Oil analysis is a critical step in proactive engine maintenance and is overlooked far too often.

MER Equipment provides a comprehensive oil analysis service that allows you to see what contaminants are in your oil, identify issues before they happen, and track your progress along the way.

For more information on our oil analysis service, contact our service department today.

Torsional Vibration Analysis

Destructive torsional vibration occurs when different pieces of rotating equipment don’t get along.

When designing or building engine-driven equipment, it’s important to consider the torsional properties of the different components being joined. Failing to account for these internal forces can lead to excessive noise and vibration, poor performance and even catastrophic failure.

Fortunately, hazardous frequencies can be identified through a Torsional Vibration Analysis (TVA). TVA testing will help enhance equipment design and identify your optimal engine speeds, protecting engine & generator components from harmful frequencies and ensuring years of reliable performance.

MER Service Checklist

This is the checklist our Dealers & Mechanics use to ensure your equipment is ready for the season.

  • They check all fluid levels and record model and serial numbers for entry in the MER database, then completely survey your equipment as described.
  • The engine systems checklist includes visually checking the oil filters, finding which oil is used (fluid sampling is also available.) The equipment is checked for external leaks.
  • The exhaust system, including the flex and exhaust manifold, is checked. Bolt tightness is tested and the thermo blankets are examined.
  • Cooling system checks include the fresh and raw water pumps, sea strainer, coolant level, belt tension, and pulley condition.
  • Antifreeze protection is verified, hoses, clamps, zincs, and the pressure cap are thoroughly examined.
  • Next is the intake air system. Further checks include the engine mounts, a compression test, alignment check, alternator connections with grounding isolation or battery switch, wire harness & plugs, mag pickup, battery condition, battery terminals and cable connections.
  • If so equipped, they will also check starter relays, glow plugs, ignition switches, instruments/gauges and safety shutdown operation.
  • On generator sets, they check the switchgear, the rear bearing, the voltage regulator, and connection wiring.
