Does anyone know if you can swap booms from a 1085 manual to a 1099 electric? Are there any modifications needed ? I'm cosidering buying a 1099 but need the extra length, I already have a 1085 thought about the swap if possible.
Even though the boom diameters are different between the 1099 and 1085 (post-2000) model Scotty's, the plastic/nylon male end on both booms are symetrically identical. Just remove the set-screw, swap, and install the set screw back. You could even put the telescoping booms from an 1106 on your 1099 if you wanted. Again, assuming your swap is between post-2000 Scotty's. Some Scotty dealers sell the telescoping boom assembly loose for about 90 bucks to upgrade fixed-boom downriggers.
I have just replaced a 24'' boom on my Scotty electric with a telescopic one, bought at Outdoor Emporium, about $84. Diameters are different, but each boom comes with a plastic adapter which fits all Scotty electrics.
