I just bought a brand Hydra Sport with an Evinrude 150 Ficht Ram injection. The boat is barely a month old. I have put quite a few hours on it though. Maybe in the 40-50 hour range. I heard knocking noises from the lower unit yesterday (our first day of vacation) and inspected the lower unit when I got home. I found metal shavings on the fill plug magnet! Lots of shavings. The dealer requested that I bring it in right away. This is a bummer for our vaction. The dealer told me he ordered two lower units for two other customers Friday too. Is this a Known problem for Evinrude? Heads up to all you new Evinrude owners out there. If you hear something like a knocking sound while running faster than 2K RPMs it could be the gears in the lower unit.<br />If anyone has any insight on this please respond. The good thing for me, it'll be covered under my 2yr warranty and I'll be getting a new replacement unit instead of a repair.
