Just purchased a 2001 Ranger with a 150 Yamaha vmax hpdi with 22 hours on it from a private party. We took the boat out to test drive and everything ran great, it did about 50mph, which we predicted it would. Still, we wanted to make sure it was okay, so we took it in to our local Yamaha dealer/shop to get the engine looked over to make sure everything was as it should be. Once we got it back, the motor lost its “edge”, it had no get up and go and we could only get it to go 38mph. We thought it might be the spark plugs, so we replaced all of them. Took it back out on the water and it ran awesome! Performed how t should and was back up to 50mph! We drove around a bit and opened it back up to get back to the trailer. Half way there the engine started to make a big clunking noise. We **** the motor off right away. We turned it back on and the noise was still there. Have read it could be the lower unit or possibly the power head?
