I have the same FourWinns and just had the shift cable replaced because it took brute force to shift -- My mechanic used the factory parts and it is now finger tip once again -- He says the corrosion just gets to it, so you can get used to about three years of use until next time -- Happy boating --
The volvo exact cables will last much longer than the factory supplied teleflex cables. The cable itself "inside the jacket " on a teleflex is a s.s. core where a exact cable is a cable type core with a coating for imporoved throttle and shift feel and also provides longer cable life
