I have a similar cable problem (I think)- I also have Tracker 17 TX-- My problem is that I am not able to engage throttle to forward and reverse.-- The cable throttles seem to move when I move the throttle shift forward (to engage) as well as reverse??

the motor fires up good-- but I don't know if this is cable issue (where it's not making the motor engage--or if it is something different)

any ideas-- Hate to bring it in the shop-- $$$, or I may simply need to get off the dime and do it anyway??
