Trolling motor ??? for OBJ

[Darrendude]

I just got a used omc corba trolling motor. It has a switch on the foot pedal for 12volts/24volts. I have it hooked up for 12volts. Will it run faster, have more power with 24volts ??? Also how many rpm's (in general) does a trolling motor (approx. 50 lbs thrust) turn in high speed out of the water???<br /><br />OBJ can you give me any specs on this , thrust, how old ,ect <br />mdl# OBF4A<br />ser#H2623183<br /><br /><br /> Thanks so much<br />Great website!

anyone?

Re: Trolling motor ??? for OBJ

don'y know about the rpm's but a 24 volt set up will deffinately make it stronger/faster. Why do you want the rpm's?

Re: Trolling motor ??? for OBJ

Darren, It won't necessarily be any faster, but it will definitely have more thrust i.e. it will get you up to full speed quicker. The RPM will be about the same either way. Other advantages of 24V setup is less amp draw which equates to longer run time, increased battery life. Don't expect any increase in speed however.

Re: Trolling motor ??? for OBJ

you also shouldnt run troller out of water....dry<br />24 volt setup will run longer than 2 12volt par.

Re: Trolling motor ??? for OBJ

Why drowned? When I hook up 12 it is a lot slower and less powerfull than using my 24. Is it my set up or what?

Re: Trolling motor ??? for OBJ

Ya' caught me off guard Darren.... <br /><br />Yeah I'll get ya' the info no problem. Don't have my book close right now. When you go 24V, the rpms speed up. rpms = thrust. Not sure of the ratio or stuff like that. That's why you can pull yourself in the wind on 24 and not 12. My OMC is a straight 24 5 speed. Won't trade it for nuthin'. <br /><br />And ya' don't want to run her long outta the water as Bass T. said. They do generate some heat in the speed resistors and the heat is disappated through the motor housing metal. Water helps keep things cool.<br /><br />I've also noticed that guys with 12/24 motors tend to use the 12V a lot and have one battery go low. That's something to watch for.

Re: Trolling motor ??? for OBJ

Thanks guys<br /><br />I bought this motor off ebay last week and already regret it. It hardly moves my little boat and there was no wind at all. The foot switch started not working too, unless I stomped on it. The seller claimed 50-60 lb thrust. But I find out today that the higher thrust Cobra has the 12" prop and mine does not. So I am guessing its the 42 thrust mdl. 12v/24v. <br /><br />The seller also said he was getting water in the motor housing and he replaced the seal. What happens to the motor if water gets in the housing? Can't be good, but is it fatal? I will get another battery tomarrow and try the 24vt set up. I wanted to send it back , but the seller aint going to take it. Said it ran great for him. <br /><br />Where can I get parts for this motor? Or should I save my money and buy a new minn kota at WallyWorld for $419 for a 55lbs bow setup? Have also seen remanufactored minn kotas in the low to mid $300. I paid $110 for the one I got on ebay<br /><br />Again<br />Thanks all, this site is a fantastic source of knowledge and is truely appreciated

Darren....parts for your trolling motor are still available at any John/Rude Dealer.<br /><br />Water in the motor housing is not good but not fatal unless it's not taken care of.<br /><br />I think once you get the kinks outta the motor, you will like it.

Thank OBJ, did you have a chance to run my mdl # to see what exactly I got?<br />mdl# OBF4A<br />ser#H2623183<br /><br />Thanks again

Re: Trolling motor ??? for OBJ

Not yet Darren....I'm at work.... They frown on outboard books here. See what I can dig up when I get home.<br /><br />EDIT: OK Darren....year is 89-90. Thrust is in the 42 to 45lb range.

Re: Trolling motor ??? for OBJ

Hi there fatpratt. I've seen these switchable motors that allow different voltage inputs but top RPM was the same, they just give more thrust in 24V mode. Top speed remained nearly the same.<br />How much additional speed do you get with yours?

 

[Darrendude]

Re: Trolling motor ??? for OBJ

"they just give more thrust in 24V mode. Top speed remained nearly the same."<br /><br />I hope i get more speed with 24 volts. This motor barely moves my boat on 12 volts. Can some point me to a diagram of how to wire my motor and batteries to operate in 24 volts? And whats the easiest way to charge the 24 volt system. I would hate to have to disconect the batteries to charge them. They are under the bow deck I built, hard to get to.

Darren – you are in California. Ebay sellers are not exempted form California retail/seller laws. Ebay is in California, too. Their policies adhere to California’s consumer protection laws.<br /><br />Did you by any chance pay with a credit card via PayPal? If so, pack it up and send it back with a tracking number. Write your credit card company a quick note disputing your purchase of faulty merchandise, include the tracking notice, and I guarantee you will receive a full refund. Even is the seller said “as is” and had some other info like “runs great”, or even just “runs” you can have the charges reversed. You have 60-days to ‘dispute’ the purchase. This is a federal law.<br /><br />NEVER attempt to reverse a credit card payment thru PayPal, tho they are going to want to handle the dispute and will send you email saying so. Ignore it! PayPal recently settled a class-action lawsuit over their practice of refunding your money as required by federal law, then taking their handling fee percentage out of that refund when it was collected from PayPal. PayPal claims to be exempted from the fed law; the suit settle out of court so no precedence was set. Also, it is possible during the time you are trying to deal with PayPal the 60-day clock may run out on your right to challenge the purchase with your credit card company.<br /><br />If you paid with an atm card, check with the card’s sponsor. Many of them have a free benefit that warranties anything you buy for a limited time; often 30-days or 60-days. They usually exempt consumable stuff or stuff with a published ‘life’ … like batteries. If your atm card is a visa, you are in luck. Visa was pressured into expending many of the same benefits for challenging cc purchases to their atm cards. Some other sponsors followed suit. Again, check with your card’s sponsor.

Re: Trolling motor ??? for OBJ

18rabbit,<br /><br />Yes I did pay for it thru paypal via a credit card. Thanks for that info, I will keep it in mind. I am going to try the 24 volts first and see what happens.<br /><br />Thanks for your input

Re: Trolling motor ??? for OBJ

Darren...to connect batteries for 24V..connect them in series. Run a jumper from the negative terminal of one battery to the positive terminal of the other. Use the remaining negative and positive terminals to run to the trolling motor. That's 24Volt....

Re: Trolling motor ??? for OBJ

OBJ <br /><br />Thanks, I know that much but how do I wire the motor? It has 3 wires coming out red, black, and white. Also, is there an easy way to charge these batteries after they are wired in series? Or do I need to diconnect them to charge? I only have a 12 volt charger.<br /><br />Thanks

 

[OBJ]

Re: Trolling motor ??? for OBJ

Tell ya' what Darren, drop me an email and I'll get a diagram off to ya'. Keep forgettin' yours has a 12/24 switch on it. Basically, you have three wires coming from the motor head. Probably red, orange and black. Black is common ground to both batteries. Connection wise, red wire goes to one battery positive post and the orange to the other battery positive post.<br /><br />Some chargers out there will charge batteries connected in series with no problem. You can get a look at these on iboats mega mall. Just do a search for battery chargers.<br /><br />If you still need the diagram....just email me.<br /><br />outboardjim@comcast.net <br /><br />Be glad to help.

Re: Trolling motor ??? for OBJ

I just got another new battery and will try the 24 volts tomarrow, if I can wire it ok.<br /><br />I assume I can charge (2) 12 volt batteries hooked in paralel?? I will wire them in the morning in series and hope the motor has more ummmmff.

 

[Darrendude]

Re: Trolling motor ??? for OBJ

Well, I wired up the 24 volt sys ok went out on the lake and it worked much better, for about 5 mins then quit. I opened it up when I got home and one of the brushes broke off, that explains why it died. POSAnyone know where to get parts on the central coast?
