Exhaust System Maintenance Tips For A Worry-Free Spring Launch

Exhaust Failure

Centek Industries offers the following pre-launch maintenance tips to help boat owners avoid problems with their exhaust systems during the boating season.

• Inspect and replace worn impellers
• Check water pump and replace or repair as needed
• All screens and traps should be free of debris
• Check all hoses and clamps for wear and make sure clamps are tight and secure
• Visually inspect the muffler for these signs of damage from excessive heat: bubbling or flaking paint; discolouration; melted stickers and/or salt deposits.
• Check external rubber flappers for cracks, dry rot or other damage
• Thru hulls should be free of obstruction. Check to make sure a critter hasn’t made a winter home in the exhaust tube or muffler.
• Make sure seacocks are open and functioning properly before startup

Spring is also a good time to consider improvements to your exhaust system.

If your boat’s muffler is made of plastic, consider upgrading to Centek components which are made from high–temperature, flame retardant resin and which are also Lloyd’s Register Type approved and meet or exceed the ABYC-P1 standards.

Sound attenuation. Options are available to make the system quieter or give it a more pleasant tone.

Install a check valve to help prevent water from flowing back into the engine or genset.

If you’re re-powering or upgrading your generator, make sure the exhaust system is properly sized – existing parts and components may not be compatible with your new engine(s) or genset.

Get rid of the splash and gurgle you hear when the generator is running. The Centek GEN-SEP™ is specially designed to reduce this common source of exhaust noise.

Get rid of the sheen. A Centek Gen-Kleen™ system eliminates the sheen around your boat when the generator is running and a Centek BilgeKleen™ filter system does the same thing when your bilge pump is running.

Centek’s engineering staff has more than 80 years of marine wet exhaust system design and innovation experience. The company has designed, engineered and built more than 15,000 custom marine exhaust systems for ski boats, yachts, workboats, military and law enforcement vessels and many of these designs are used continuously to build exhaust systems for thousands of new boats and refits annually.







Neptunus 650F Review

Neptunus 650F 400

By Andy Adams

Over the years Canadian Yachting has had the pleasure of doing several boat review articles on new Neptunus models and we are familiar with the qualities that Neptunus is famous for. They have all been exceptional yachts, but this is the one I would most want to own myself. It’s a personal choice and a matter of taste as to whether you would prefer to have a sedan express model or a flybridge but in my opinion, the flybridge layout offers some wonderful attributes.

We met with Neptunus Managing Director Jan Willem De Jong this past fall to take the new Neptunus 650F out in Lake Ontario.

The Other Virgin Islands

Sunset off St John

By Mark Stevens

I was first seduced by the United States Virgin Islands during a ferry ride from St. Thomas to Tortola to begin one of our earliest British Virgin Islands charters nearly twenty years ago.

A perfect sunset off St. John with St. Thomas views for backdrop.

Clearing Pillsbury Sound, surrounded by voluptuous emerald mountains as the ferry sliced through royal blue waters, I was struck by the unspoiled ambiance of St. John, the island gliding past our starboard beam and the irresistible charm of a village called Cruz Bay visible from our quarter stern.
