I have a 1998 TR-20 single console. I just replaced my outboard with a 2011, Mercury Optimax Pro XS, 200 3.0 L. I have a 6" hydraulic jack plate and hydraulic steering. I tried a Fury, 3 blades, 25 pitch and after the break-in period, I could not get past 5200 ffice:smarttags" />RPM. The boat would start to violently chime walking. That’s something I’m not wishing to live with or learn how to overcome. fficeffice" />>>

I replace the Fury with a Tempest plus, 3 blades, 23 pitch prop. On a full tank (56gal) of gas, two persons in the boat and equipment I was able to get up to about 5000 RPM, 60MPH and steady. However, at about 5400-5500 RPM, 65MPH the boat would begin to once again violently chime walk and had to back off. >>

Any advise on how I can run at the WOT 5800RPM or between 5600 5750 RPM and keep the boat from entering into a violent chime walk. I was thinking of going to a 21 or 23 pitch Trophy 4 blade. >>
