Bump. So i had some interest in the trolling motor but if anyone else is interested I reached out to Minn Kota for info about this exact model. Here is what Minn Kota said:
That is a 42" shaft on that motor when it was made. The brushes are a 188-094 for $5.14 per brush. You would need to order 2 brushes as they don't come as a set. Plus you would have replace all seals and orings in the lower unit. Now that seal kit is a 2889460 for $6.17.
Thank you,
Jennifer
