When is the time to request assistance with your marine diesel engine?

While a well-maintained marine diesel engine can deliver reliable performance for many years, neglecting periodic maintenance can lead to serious issues that compromise reliability. Here are some common warning signs to watch for:

  • White or gray exhaust smoke, which may indicate water contamination in the fuel or a head gasket issue
  • Lack of water from the exhaust, signaling a potential problem with the cooling system
  • Excessive black smoke, often caused by incomplete combustion
  • Lack of power, which could stem from fuel delivery issues
  • Power fluctuations, meaning inconsistent RPMs that suggest injector issues, fuel line blockages, or governor malfunctions
  • Slow idle speed, which may point to incorrect adjustments or wear in the fuel injection system

I just bought a 2005 Catalina 36 and needed some engine maintenance right away. I received both prompt and exceptional service from Lukas and his team. I was so impressed with everything, from timely communication, transparent pricing, and pictures and videos so I could see what needed to be done, as well as the completed work. My friend with a Hunter 36 recommended him to me, we both are very happy customers!!

Lukas and Royal Marine serviced my Yamaha outboards and various pumps and electrical systems on my boat. I found their communication and work to be excellent and I will continue to use them for all my maintenance needs going forward.

It was a pretty seamless experience. I had a lot of moving parts and pieces. Lucas and his team helped me accomplish my goals in a professional and timely matter. I would highly recommend them for any boat service. I had his team do an engine swap on the starboard engine, out drive service, replacing all 4 manifolds, and complete service to the port engine. His recommendations were very helpful as well. I will be using them for any future repairs and maintenance. I cant recommend them enough! 10/07/2024

Absolutely Outstanding! Honest, dependable and shows up on time ready to work. I have a 1988 Trojan 38’ Pleasure Cruiser with very hard to reach twin 350 V8s. Lukas and his team completed several repairs and general maintenance to keep my boat reliable. Equally important: every estimate was accurate in required parts, time and cost. ROYAL MARINE is competitively priced and certainly the best value. 🌴🦅

I’m giving Royal Marine a 5 star review ! To thank them for their awesome service they have been giving me on my Sea Ray Sedan. Every time I call them or send them a message I get a response right away. They have great communication and are very consistent with giving me updates while working on my Sea Ray. Definitely will be returning for their services with Lucas and his crew.
