Whether you ride an upgraded, high-horsepower Yamaha or are just working with the stock builds, you have probably noticed that there can be some issues with managing the oil pressure on these models. It’s a pretty well-known fact that Yamaha engines can be quite inconsistent when it comes to oil management, and dropping to low pressure is more common than a lot of riders would like.
While this is true for most Yamaha jet skis, it is particularly noticeable in the high-horsepower engines, as that increased revving can cause a big drop in pressure.
Luckily, our friends over at FuelTech USA decided to tackle this problem themselves, engineering a pair of specially designed parts to ensure your Yamaha PWC maintains its oil pressure throughout even the most strenuous rides. The first of these products is the billet oil pan, which serves to increase the oil pan’s capacity by four quarts and incorporates a baffle solution that keeps the oil inside the suction tube. This works to ensure that the oil doesn’t escape, especially on those higher-powered engines.
Their second solution is the billet oil pump, a direct-fit unit engineered for the stock block on Yamaha 1.8L and 1.9L engines—including both supercharged and turbocharged jet ski models. This pump features an adjustable regulator that allows you to dial oil pressure above 100 PSI across the RPM range, offering robust protection for your engine.
As you surely know, having low oil pressure can result in some pretty nasty issues for your PWC. Without adequate oil circulation, critical engine components like bearings, pistons, and the crankshaft are left vulnerable to heat, friction, and premature wear. In the worst cases, it can lead to full engine seizure or catastrophic failure—so it’s definitely important to make sure you’re not putting your PWC at risk.
If you’ve got a Yamaha PWC and you’re looking to ensure that oil pressure doesn’t hurt your engine, be sure to check out the oil pump and pan from FuelTech USA now!
