Boat Therapy: Giving Your Yamaha 150 Outboard a Spa Day (aka Flushing)

17 Sep 2024

Is your Yamaha 150 outboard feeling a little salty? Like it needs a good detox after a long day splashing around in the ocean? Well, darling, it probably does. Just like we need our green juice and face masks, our outboard motors crave a little TLC, too. And that, my friends, means flushing. Not the panicky kind, the engine kind. This isn't just some nautical chore; it's an act of self-care for your boat (and your wallet). So grab your metaphorical cucumber slices, and let's dive into the refreshing world of outboard motor flushing.

Flushing your Yamaha 150 outboard is basically giving it a deep cleanse, rinsing away all the corrosive saltwater and debris that can build up and cause problems down the line. Think of it as preventative maintenance, a little insurance policy against costly repairs and premature engine aging. It's the secret to keeping your outboard humming happily for years to come.

Historically, flushing outboards wasn't as big a deal. Older engines were often simpler and more robust. But as technology advanced and outboards became more complex, the need for regular flushing became increasingly important. Saltwater, especially, is notoriously harsh on engine components, leading to corrosion, clogged cooling passages, and decreased performance. Flushing with fresh water helps neutralize the salt and wash away any lingering particles, preventing these issues from taking hold.

The main issues surrounding flushing a Yamaha 150 outboard relate primarily to incorrect procedures. Using the wrong type of flushing device, not running the engine long enough during the flush, or forgetting to flush altogether can negate the benefits and even potentially cause harm. That's why understanding the correct flushing method is crucial.

Flushing your outboard involves connecting a flushing device, either earmuffs or a flushing bag, which supplies fresh water to the engine's cooling system. With the engine running, the fresh water circulates, displacing the saltwater and cleaning out the internal passages. This process removes salt crystals and debris, protecting vital components like the water pump impeller, thermostat, and cooling passages.

Benefit 1: Extended Engine Life: By removing corrosive saltwater and preventing buildup, flushing significantly extends the lifespan of your outboard.

Benefit 2: Improved Performance: A clean engine runs more efficiently, leading to better fuel economy and overall performance.

Benefit 3: Reduced Maintenance Costs: Regular flushing prevents costly repairs by addressing potential problems before they become major issues.

Action Plan: Gather your supplies: garden hose, flushing device (earmuffs or flushing bag), and a bucket (if using earmuffs). Connect the flushing device, turn on the water, start the engine, and let it run for 10-15 minutes. Turn off the engine, disconnect the flushing device, and you’re done.

Step-by-Step Guide: 1. Connect the flushing device. 2. Turn on the water supply. 3. Start the engine. 4. Let the engine run for 10-15 minutes. 5. Turn off the engine. 6. Disconnect the flushing device.
