Super User tcbass Posted August 4, 2016 Super User Posted August 4, 2016 So I'm attempting to replace the current Minn Kota Fortrex on my Stratos bass boat to a Minn Kota Terrova. I spoke with Minn Kota (they have a chat feature, which I like much better than talking on the phone) and they said that the mounting holes for the Terrova and Ulterra are the same (same footprint I guess) while they are different for the Fortrex. The Minn Kota employee said I'd have to drill new holes or I could use a Minn Kota MKA-47 universal quick release bracket and would not have to drill new holes. The bracket costs $149. I would like to switch the Terrova to an Ulterra this winter when I can find it on sale and I thought that using the bracket might make it easier, but if I go the drill hole route rather than the bracket the holes are already drilled so it wouldn't be too much work changing the two out, not like it was when I went from the Fortrex to the Terrova. The Terrova seems to have a bigger footprint so it could potentially cover the old holes. But if not, I am worried that I'll have 4 big, uncovered, and unsightly holes at the front of my boat though. I don't need a quick release bracket for any other reason, I don't ever take my TM off my boat. I also hate the Fortrex so u don't plan on switching back and forth, the Terrova or Ulterra will be permanent. What would you do, just drill new holes or use the bracket? Quote
Super User J Francho Posted August 4, 2016 Super User Posted August 4, 2016 With the bracket, you could switch between the two - an assumption on my part. I would prefer that setup, since there are times when I'd want a cable steer, and others when I'd want a electric steer. I'm not sure there any issues with the bracket, so hopefully someone can comment on that. Quote
Super User Scott F Posted August 4, 2016 Super User Posted August 4, 2016 I've never had a problem with drilling new holes in my boat. If the old holes will be covered with the new trolling motor, I fill them with silicone. If they will be exposed, I put in a stainless screw with a grommet, washer and nut, adding silicone to the hole as I put in the screw. My boat is 28 years old and has had 3 different trolling motors, downriggers, and 6 or 8 different depth finders with transducers. I have a bunch of old mounting holes! Quote

Does it have to be marine grade silicone? Quote
Super User Scott F Posted August 4, 2016 Super User Posted August 4, 2016 I've never used marine grade silicone before. I don't keep my boat outdoors and don't use it in saltwater. The regular RTV silicone I've been using for years has always held up. Quote
"hamma" Posted August 4, 2016 Posted August 4, 2016 Id get the bracket, and hold onto the fortrex as a backup in case you ever come to a point you "need" it,...it would be an easy swap as well Quote

Super User fishnkamp Posted August 4, 2016 Super User Posted August 4, 2016 If you want an Ulterra why are you not going for that first? Now I would use 5200 Marine Tex to fill in the holes. It can be lightly sanded and painted to closely match you boat's color then I would drill and mount my new trolling motor. Anything that makes it easier for you to remove it makes it easier for someone else to remove it! Quote
S. Sass Posted August 4, 2016 Posted August 4, 2016 Just my opinion use the Minn Kota MKA-47 universal quick release bracket. I prefer as few marks scratches and holes as possible for equipment attached to my boat. Once you cut into it you can't undo it. Quote

Super User Further North Posted August 5, 2016 Super User Posted August 5, 2016 Quick release, every time. Only a little more expensive, and it gives you the best of both worlds. Quote
Super User A-Jay Posted August 5, 2016 Super User Posted August 5, 2016 I went with the bracket system. Makes motor switch out & removal (if & when TM repair is required) very easy. Once it's on - there's no issues. A-Jay Quote
Super User tcbass Posted August 5, 2016 Author Super User Posted August 5, 2016 Well, since I just spent a ton on this boat I decided I should save some money and went with just mounting it regular. It worked out well. Thx for the help! Quote

Terrova is still going strong, no damage. I hit plenty of rocks with my Terrova. Most with no effect. I did manage to bend the motor shaft once though. Turned it into a little water pump that squirted water into the armature until the whole works shorted out. Check the prop to make sure it's not wobbling. Quote

Could this happen with the MK quick detach mount? Because if that's the case I'd rather mount it directly to the boat. If not, I can see how a quick release mount would be nice if I had to take it off for repair. Quote

The MK mount is secured to the deck the same as the TM would be. Then the TM slides onto the metal mount A FULL 24 Inches. Anything is possible but unless the mount is somehow attached incorrectly, it's not going anywhere - That's a 112 Fortrex picture below (62" shaft") It''s a Beast of a motor & It's rock solid on a MK quick release mount..
