Not sure if this is the right section or not, but I need to know what length shift cable i need for a sunsation aggressor 25'.
Any help is appreciated.

transom shift cable or control cable. If transom cable and you have a bravo drive, there is only 1 to chose from, if its a alpha, your choices are 2, if its a control, it depends on the length from the control back to the shift adapter.

thinkin about changing both, because I dont know which one is messed up. Its a bravo drive.

whats it doing,

Hard to shift into forward, and somewhat hard to shift into reverse. I think im gonna take off the cover and test them one at a time. Hopefully I can figure it out.

undo the 2 cables at the converter box in the engine compartment and shift them independently, you should be able to find the bad one, more than likely transom shift cable.
