Does anyone have a drawing with dimensions for pn.91-818836A-1 drill guide for installing new lower shift cable in older style bell housing? Or does anyone know if the new teflon coated inner cable can be installed in the old style outer housing?? Ken

i have never used the drill guide and have installed a lot of these cables (work on boats for a living 37+ years Mercury Master Mechinic and Mercruiser Certified) just drill one size bit larger at a time until you get to the right size and yes the new cable will work just fine.

thanks,,,,Ken
