Be Sure the Exhaust System is on Your Spring Launch Checklist to Avoid Problems This Season

Spring Exhaust Maintenance

Apr 6, 2016

Salt deposits (left) and discoloration (right) are two signs of potential exhaust system problems that should be addressed before launching your boat this spring.

Most boat owners have a checklist of maintenance items to be performed before spring launch.

Leading exhaust systems manufacturer Centek Industries suggests the following items be included on checklists to avoid exhaust system problems during the boating season.

• Inspect your exhaust system for cracks or other signs of physical damage.
• If you see salt deposits, your muffler is leaking water. If you see any discolouration, your muffler has experienced overheating, damage has occurred and may potentially leak. Before considering a repair or replacement, determine why the leak occurred. Almost 100% of the time, this type of leak indicates that the muffler experienced overheating due to a loss of cooling water in the exhaust stream. If the cause of overheating is not corrected, any repair to your muffler will be a short term solution.
• Inspect and replace hoses that are worn, dry rotted, damaged or cracked.
• Tighten all hose connections. Ideally, hoses should be double-clamped.
• Add sound dampening material on the base of the muffler to reduce noise through the hull and on deck.
• To reduce noise from overboard cooling water discharge, consider adding a Gen-Sep to separate the cooling water from the exhaust gasses. The exhaust gas is then discharged to the atmosphere and the cooling water is discharged below the water line, which will eliminate the splash you hear when the gen-set is running.
• If you’ve repowered, you may also need to replace your exhaust system. To get the most from your new engine or gen-set, it is important to make sure that the exhaust system is properly sized. A properly sized exhaust system provides the best sound attenuation and stays within the backpressure limits set by the engine manufacturer.

While Canadians may have been slower to warm to pontoon boats than our southern neighbours, that’s definitely changed as we see more of them gracing our waters every year. The latest data shows pontoon boats now represent around 30% of all new boats sold in Canada and it’s easy to understand why – with their interior space and tremendous versatility, pontoons are near-perfect family runabouts.

Cruising Georgian Bay’s 30,000 Islands: Canada’s Freshwater Paradise for Boaters

The Plan

It’s a beautiful morning as we perform our pre-departure checklist, fire up the engines and prepare to release our lines. And if the long-range forecast of very low winds coupled with plenty of sunshine holds, that’s exactly what we need for the areas we plan to explore on this trip! 

We are departing Midland for a week of visiting some of the islands and anchorages within Georgian Bay’s “30,000 Islands” – specifically those along the western edge. These are the less protected islands which face toward wide-open Georgian Bay, where boaters often have to depart the small craft route and work a little harder at setting the hook but are then rewarded with magnificent western views, stunning sunsets, and so much to explore!
