Power to new 24 vt motor

14 posts in this topic

Finally took the plunge and got a new 24 vt Minnkota. Couple questions...the plug in the bow is only 2 prong, dealer doesn't have a matching male end for the motor; can i just eliminate the plug and wire it directly, or should I buy both ends from the dealer and try to install the new female end in the boat (doesn't look like it will fit right off)? I've read I need a fuse in the line...the manual says "a 60 amp manual reset circuit breaker". I guess I have to do it like the manual says, but, again, dealer doesn't have one, and I haven't seen anyone on here mention it in tons of discussion. At least the mounting of the motor look straightforward...thanks

You will enjoy your new motor. Don't wire it directly. You want to be able to unplug the trolling motor when charging the batteries. If you can, try and find the matching male end. Maybe try another marine store or a Fleet Farm type of store. There are only a few manufacturers. If you can't find it, then by a new pair. Go with a resettable breaker mounted at the battery. The 60 amp ones are hard to find exept for the MinnKota brand which are very expensive compared to the 50 amp ones. I've been using a 50 amp one with an 80# thrust motor and it has never tripped even when running close to max power.

What kind of Minnkota motor is it and how many wires "prongs"

Your going to want to slow way down here if you hook up the 12 volt feed "if there is one" incorrectly you will FRY your board.

The correct plug should used.

Thanks hookmaster, I'll see if I can find a 60 amp first... the motor is an 80 lb, 24 vt., Riptide ST, copilot, autopilot...I spent $$$, so I'll go reeeeely slow:) The 2 wires coming off the motor are simple red/black with pigtail ends that will of course need to be removed. The boat is a 2000 Champion Bay boat; the female plug in the boat currently is 2 prong, which seems like all the motor needs as it only has 2 wires. However, the couple plugs I looked at at the local marine dealer had 3 prongs, why, I don't know. The only bigger/more complex motor out there would be this same type, only 36 vt/101 lb thrust. There is also a seperate wire with what looks like a transducer plug end...don't know why it's even there, as I didn't buy one with universal sonar.??

How many wires go to the female plug from the batteries. If it is more than 2 the female is probably a 12/24 connection. Then I think you need the 12/24 male counterpart. If it is only 2, then you can use one that has 2 prongs/wires.

I would be careful about just throwing a 60A circuit breaker or fuse on the system. If the wire isn't sized to handle this current load you may find yourself testing your fire extinguisher.

From what I've seen, a 50A breaker is the max for 8ga wire, 80A is the max for 6ga wire.

Of course, using a smaller breaker on larger wire is OK - just not the other way around.

Besides fuse/breaker sizing, choosing the proper gauge wire is important to minimize voltage drop since voltage drop just wastes power as heat.

For instance, say that you need a 50A circuit. Well, strictly by ampacity, 8ga wire is OK.

However, assuming a 16ft boat and a a few extra feet for routing, the voltage drop is over 6%. That's too much, IMO. Stepping up to 6ga cuts the voltage drop to about 4%. Going one more step to 4ga cuts the voltage drop to about 2.5% Generally, for non-critical circuits, I've seen recommendations of 5% or less voltage drop.

60 amp is straight out of the manual so it should be good. I'll have to see what size wire runs back to the panel from the plug. I talked to MinnKota today and they said with the 24 vt motor the 2 wire plug is fine. Thanks for the responses guys.

Sure, I believe you that 60A is straight out of the trolling motor book.

However, I assume the wire is already in the boat and that is what dictates the maximum size circuit breaker you should use - not what the trolling motor book says.

I see what you're saying. Now how do I determine what gauge wire is in the boat?

It should say right on the insulation covering the wire. It should be really thick and stiff. The thicker the wire, the better gauge the wire is.

Perhaps you'll get a break and it'll be on the wire but, IMO, that's 50/50 chance.

You could look up "wire gauge table" on the Internet and you should get information listing the diameters. The numbers listed will be diameter of the bare conductor, not the insulation.

Another option would be to contact the boat manufacturer and ask them.

My wires actually say "6-gauge" right on them, so who knows, I guess I'm wrong. ha ha.

Well, actually, I still say 50/50 chance. My wires say nothing on them. smile.gif

I've found mine to be 8ga using measurement and comparison to other wire samples.

      Crawlers work great for a mixed bag of fish.  Fresh cut bait like suckers or shad work great for channel cats.  I've never fished North Lake in Red Wing. Have fun!

      Have you or anyone tried North Lake in Red Wing by Treasure Island?? Just curious if anything have been biting there?

      I seen this I seen that.....   I go and correct it once in a while... LOL  somebody has to help you peasants

      Thanks a lot phishnerd! I will give it a shot and let ya know how I do! I am hoping to get out tomorrow if not hopefully this weekend! Thanks for the tips on baiting also! What would you use for live baits?

      I would think so.  You still need a passport too.  Seems like the only change is loosening up on the mandatory check in.  You only have to if they ask you too.   I never took an RABC to exempt me from the check in requirement before this change.

      The Minnesota Department of Natural Resources has released a draft operational plan for management of the Sand Dunes State Forest, located in central Sherburne County, about 3 miles west of Zimmerman. The draft operational plan will undergo a 45-day public review from June 21 to August 4. Members of the public are invited to read the draft plan on the DNR’s website and provide comments through an online form; both are located at www.mndnr.gov/forestry/sand-dunes. The DNR will hold a public meeting to discuss the plan on July 10, 6 p.m. to 9 p.m., at the Big Lake High School cafeteria; 501 Minnesota Ave., in Big Lake. Members of the public will be invited to interact with DNR staff and learn more about the draft plan. The meeting will begin with an open house, followed by a brief DNR presentation about the plan and, conclude with an open microphone session. Last summer, the DNR organized a group of local residents, government leaders and other interested people to provide perspective and advice on management issues in the Sand Dunes State Forest. The group held six open meetings, and there were often additional people in the audience who joined in the discussion. These citizen-centered discussions helped shape the new draft plan released this week. Sand Dunes State Forest, established by the Minnesota Legislature in 1945, includes about 6,000 acres of land owned and managed by the state. It features pine plantations, rare sand dunes, wetlands, woodlands, oak savanna and prairie and is home to more than two dozen rare plants and animals. The forest is a popular recreation destination for hikers, horseback riders, hunters, campers and others. For ongoing news regarding Sand Dunes State Forest and future meetings of the advisory group, sign up for email updates . Enter an email address and then select Sand Dunes State Forest from the drop down list.  Visit www.mndnr.gov/forestry/sand-dunes for notes and resources related to the meetings.

      Welcome FM Chevy!  There's lots of fish to be caught in the Mighty Mississippi.  Plenty of spots to fish from shore right in or near Hastings as well as a little up river by the Wakota Bridge.  The great thing about the river is you never know what you are going catch. Carp, Suckers, Catfish, Walleye, Sauger, Bass, Gar, Big Ol' Snapper, Leather Necks etc..Cats are just starting to spawn so they might be a little challenging and inconsistent right now.  Try some live bait straight line rigs or cranks and keep moving.  I usually don't spend more then 20-30 mins in an area before I move on.  Good luck and let us know how you do!
