Oil & Filter Changes for Engines & Generators

Changing the oil on your boat is essential to the life of your boat engine, keeping it clean and running smoothly. Iguana Marine Group’s Oil Service includes changing your oil and replacing your oil filter (as needed) on engines and generators.

For a new boat, most engine manufacturers recommend changing your oil after the first 20 hours. After that, Iguana recommends changing after every 50 hours or at least once-per-year, whichever comes first. You can find the exact requirements for your boat’s engine in your owner’s manual.

Moreover, they could eventually cause damage to your engine and/or transmission. Let our expert techs at Iguana repair those small bends and nicks and keep your boat running smoothly & efficiently out on the water.

A marine transmission is a hardworking, yet often ignored piece of equipment. Scheduling regular preventative maintenance appointments with Iguana Marine Group will help extend the life of your transmission and keep your boat running smoothly.

Water Pump Impellers

Impellers pump lake water into your boat’s engine or generator to keep it cool while in use. Impellers work best when run regularly, but can be damaged by the debris or chemicals that are sucked in. Correctly installed, and regularly maintained impellers will insure an enjoyable boating experience.


Let Iguana Marine Group get your boat “winter-ready”. Our experienced technicians will flush the engine, drain the engine block and protect it with antifreeze.


  • Draining water from the engine, generator systems, head systems, washer/dryer, dishwasher, seawater wash down, heat exchangers, shaft coolers, transmission oil coolers, sea strainers, and seacocks.
  • We use blue -100 degree non-toxic, environmentally safe antifreeze with corrosion inhibitors. The water dilution factor increases freeze protection drastically compared to the pink -50 degree antifreeze.
