I have a 1977 Cat 27 with the Atomic 4. Original Morse dual engine controls are side mounted in the cockpit. The throtle control was getting hard to move when I put her away last fall and now it won't budge. I have taken the controlls out and confirmed both the throtle cable and gear shift cable are free and clear. After many sprayings of WD-40 the throttle shifter will not turn inside the main control. Catalina Direct wants $550 for the replacement kit...I don't need the mounting brackets...any ideas where I may be able to find a used or more affordable replacement....or free mine up? I'm in Boston. Thanks
