Have a 1995 Wellcraft Coastal 23 and 1995 Johnson OceanRunner. Boats past due for shift and throttle cable replacement. I am not sure how long the replacement cables should be and really want to be certain of required length before ordering them in spring. Is there a way to determine required cable length without removing existing cables? Want to account for bends and such which can ultimately mean the difference between a foot or two. Oh and thanks for the great advice found on the site.
