Getting ready to mount a new MK Terrova on my 2005 189 Sport. Anyone had any experience with this aluminum plate? I can remove it but underneath are 2 round pucks keeping me from getting any kind of flat surface to mount to. If I keep the long metal plate I need it to extend to accommodate the new TM plus trying to deal with the height of the tension springs. I guess fabrication and welding is in order. Anyone have any ideas?

I have a 2002 188 Sport with a similar plate. I mounted directly to that plate. I wanted to adjust the position of the trolling motor when loading and unloading from trailer, so I bought the sliding TM mount from Minn Kota and mounted that to the plate on nitro. You can also completely removed the TM with this plate as well.

Thanks Jeff!
Glad you replied because I was awake at about 3am in my garage wondering if the MKA-16 (I think that is the mount you have) would fit over top of the tension spring block with the springs removed - from the pictures it looks like it fits perfectly. Only question I have is with the tension springs removed and now that block is flat on the aluminum plate, what holds that plate snug to the boat? Did you drill through the tension spring block, through the plate and all the way into the fiberglass and lock it down with a flush mounted screw and nut under the deck?

On mine, it locks in with a small pin through a shaft. I could actually remove the entire aluminum plate by loosening the back fastener and turning the entire thing and it will pull out. So I didn't put any screws into the fiberglass, just mounted the minn kota bracket to the aluminum bracket and left the aluminum plate the way it was secured to the boat originally.

Jeff, my two metal pucks are loose. Do you happen to know what fastener is on the other side of the screws that hold the pucks down? I reached under there but didn't feel anything that felt like the shape of a nut. I need to tighten mine down because when I use the trolling motor, the force of the motor tilts the pucks and pulls up on them.

Loagz Dad My pucks are held in place by 4 nylock nuts. But I had a similar problem as you since they are stainless 1 of my four was galled and thus was not on tight and gave a little "play" I had to cut it off and reinstall a new one with hand tools. Also the underside of the fiberglass is not flat it so it makes those nuts really hard to get to and get a box wrench on

Good to know! When I try to tighten mine they just spin. I'm going to try to stick my camera in there and snap a picture to at least give me some bearings about what's what. My arm barely fits into the trolling motor plug cutout, so it's tricky to even reach the damn things.

If I remember, mine are also held on with nuts. I did tighten my back one which was loose before I mounted my TM. I think I laid in the front compartment and could reach them with a wrench to hold them as they were tightened.

I did this on my 2001 Nitro. I had a 1/2 inch plate fabricated. Then, drilled holes and used longer screws thru the mounting pucks. There is a previous thread on here where i posted pics.
Luckily I have a 14 yr old neighbor who helped me with the underside nuts.

Jeff Brekke I have been following your lead on mounting my new Terrova. Where did you put the Heading sensor puck and how did you power it? I did not want to run the leads straight back to the cranking battery since in theory it will be on and draining the battery all the time. Bow mount Fishfinder is tied to bow lights for power, any suggestions?
