One used for parts or repair is a Motor Guide trolling motor bottom housing part number 2J45494V. Last two pictures show a piece is broken off. 

We are located in Wisconsin so motors are used in fresh water not salt water.

Item is sold as is. Watch my other listings for more Outboard motor and parts, trolling motors parts and Boating items both new, used and vintage items. Shipping cost applies to the lower 48 states. Please ask questions thru ebay before bidding and good luck.  (loc White)
