Do you have abnormal engine vibration; rubber dust around engine mounts; telltale signs of possible engine mount wear or imminent failure?

It is always discomforting when you know, and actually feel, that something is not quite right.

For a little while now, while navigating under power, I felt some “new” vibrations that simply disturbed me. Putting the boat safely on auto pilot, I went down into the cabin, opened up the rear engine cowl and realized it was the propeller shaft that seemed to be the origin of the vibration. Either caused by poor shaft alignment (which I determined was not the case) or something else was causing this issue.

While inspecting the engine mounts, the most likely culprits, I noticed the rear port side engine mount was leaving a lot of rubber dust and residue around itself. With the engine stopped, I was able to move or twist the mount by hand. These are telltale signs of engine mount wear and, in the case of that particular mount, a possible and imminent mount failure - which is the last thing anyone of us would want! Consider other collateral damage that could possibly cause.

With the engine mount so worn, in addition to its proximity to the transmission and prop shaft link, this is what was causing the excess vibration while under load (forward or reverse). Plus, it means the starboard rear mount has been compensating by taking on extra stress, therefore also getting more wear and tear.

As the mounts are original (27 years old), it would make no sense to change just one. Is it more work? Yes of course, but if one is about to fail, the chances are, the others are not far behind. So, using my philosophy that “maintenance costs much less than repairs”, I ordered four new engine mounts. For our boat, the engine is a Perkins M20 diesel, so I ordered these from Part 4 Engines in the UK. I also ordered the matching hardware. If you’re going to change things like engine mounts, you might as well change the nuts and bolts too.

Another thing I consider important when changing engine mounts on a sailboat, is to make sure the mast is up and the rigging tension is properly set, as this will ensure proper prop shaft alignment. I also recommend having the boat in the water and not sitting on a cradle or trailer for the same reason. At least, plan the final engine to prop alignment when she’s in the drink and the rigging is properly tensioned.

In most cases, the tools needed are basic. Proper size wrenches, a ratchet, sockets and extensions and a sparkplug feeler gauge set. I also used the space saver scissor action jack from my car to hold the engine in place as a backup safety while I removed and replaced each mount one at a time.

Viko S35

By Katherine Stone

I am lucky to have the opportunity to helm many types of boats. I am even more lucky to sail boats on champagne fall days when many boats are either being hauled for the winter, or are already under shrink-wrap.

Not only are there great winds – usually offshore, but welcome sunshine and open waters with few boats out enjoying the last days of September. Joining me for the test sail of the Viko S35 was the former publisher of Canadian Yachting, Greg Nicoll, and the Canadian Viko Yachts representative, Eric Beauregard, who had driven down from Montreal.

Four Winns H4By Andy Adams

The well-known Four Winns brand is now a part of the international boatbuilder Groupe Beneteau and the new H4 is a great example of how the design and engineering resources of Beneteau can up the game even for a brand like Four Winns that has a long and distinguished history.

The Cadillac Michigan-built H4 is a brand-new design this year and we think it's especially handsome. The vertical stem bow is all new and innovative. It is a design feature that was chosen to give Four Winns and the H4 a sense of modern and contemporary look while the stern remains more traditional.

West Side Story

It was the last day of August and we were in Little Current heading south. Our Lasalle winter haul out was still over a month away. The question was: where to now? Friends in Meaford often suggested we sail in for a visit. We never had because we’d always moved north-south on the east side of Georgian Bay. This year we were up for something different. This was the perfect opportunity to cruise the west side of the bay.

We made the 10 a.m. bridge out of Little Current and motor-sailed east southeast in light northerlies. We’d often sailed past Snug Harbour, a nearly land-locked anchorage on the north side of Lansdowne Channel because the chart suggested we’d never make it in there with our six-foot draft.
