Twin 200's, turning stiff while running

Hello,<br /><br />I've researched all the twin setup posts, but really didn't find what I was looking for.<br /><br />I just purchased a Grady White that has twin 200 Yamahas on it. In the down position, they turn smoothly to port and starboard, while not running. Under power, it can become fairly stiff to turn. As I increase power, somtimes it will come into a range that it doesn't bind ***as much**. <br /><br />The engines are slightly toed out from one another. The other thing I have noticed is that the alignment tab under the cavitation plate on the port motor is angled out about 3 notches. The tab on the Stb. motor is dead straight.<br /><br />I noticed a new set of Twin Optimax's in San Diego that had no alignment tabs at all under the cavitation plate, simply a flat plate instead. <br /><br />I've read that one engine should be disconnected and allowed to track the other engine, then set, but I'm not willing to try that with this much power. I've also read they should be toed in, toed out, and parallel. So which is it? What about the tabs?<br /><br />My basic assumption would be to line up the engines parallel and set the alignment tabs parallel too. It seems that perhaps one engine is torquing the other, and that is why it makes it difficult to turn.<br /><br />Thanks for the help. I appreciate all responses!<br /><br />Mike

Sounds to me like you really should start with making sure you find all the grease fittings and useing them liberaly, and repeatedly till it loosens up.

Yepblaze-<br /><br />Sorry if I didn't make myself clear. The engines turn smoothly while NOT under power. I indeed have lubed all zirk fittings.<br /><br />Only while UNDER POWER does the steering start to stiffen. This seems to indicate to me that the engines are creating torque that the steering system must overcome. Since the stiff turning will disappear at certain RPM's, it leads me to believe that they are not adjusted correctly.<br /><br />Being unfamiliar with how to correctly set up counter rotating twins, I hope that someone may be able to enlighten me.<br /><br />Thanks!<br /><br />Mike

What kind of steering do you have ,and is it appropriate for this kind of power?You should be using the best hydraulic steering you can get ,or a specialized dual cable,or power steering.Trim tabs are not a factor in this equation.
