As boating enthusiasts, we know that the best outboard engine repair is vital to ensure our time on the water is safe and enjoyable. Fortunately, there are some simple ways you can help make your outboard last longer and run more reliably.
The best way to keep up with your outboard’s maintenance needs is by following its recommended service schedule, which is usually based on hours of operation. Typically, you should change the oil and gearcase lubricant every 100 hours and replace the impeller and water pump at 200 hour intervals. You should also flush your outboard with fresh water after every use because heat and saltwater can leave stubborn deposits that can clog cooling passages and cause corrosion. You should also install and regularly replace sacrificial anodes to prevent damage from the interaction of dissimilar metals.

Another simple step you can take is to regularly lubricate the PT&T unit (Power Tilt and Trim) components, fittings and pivot points with marine-grade grease. This keeps everything from rusting and helps reduce friction that leads to squeaking noises. You should also make sure to re-engage the tilt lock mechanism built into your Yamaha engine support or use an external bracket to keep the rams fully retracted when not in use, as this will help keep them immersed in a bath of PT&T fluid and protected from corrosion.
Finally, it is important to periodically remove your propeller and check for fishing line around the shaft. Left unattended, fish line can melt the prop shaft seal and allow water to enter the gear case. This will quickly destroy bearings and gears, so it is critical to catch this problem early on.
