Hey all, wondering if you can help me,? I have a Yamaha 225 HPDI series 2 2009 with 2013 Powerhead. It makes a clanking noise from the lower unit, only when in gear , both forward and reverse, It goes away with any throttle applied, I have seen on you tube and searchs that it may be normal,?, Just changed Oil and it was clean as it can be with a tiny bit metal particles & prop is tight 25 T1 (1 Piece Brass Thrust Washer) . My 05 200 HPDI never did this and I just bough this boat 1.5 months ago and its been out 3 times.
Idles @ 500 RPM and is smooth but in gear it rattles / ratchets badly until over 700 RPM then goes away...
