I've started producing an upgrade kit for 36 Volt 45" and 52" Ultrex Trolling motors as an alternative solution to the factory complete base replacement. If you have Mega 360 and Mega Live Target lock you'll really enjoy not having to brace to pull all of that additional weight up out of the water multiple times a day while you're out fishing. To install the kit you have to remove the stock spring, drill 3 holes (template provided) to relocate the upper attachment point upward in the top of the base to accommodate the larger spring, and install the replacement spring. The entire process is easily done with basic hand tools and should take about 20 minutes.
We've had multiple threads going in the Trolling Motors subforum so you could look there for more information.
Kit price is $125 + shipping and I take care of the PayPal fees. I'll be making another batch of kits this week.......Anyone interested?
Thanks,
Ron
