Will a 2 stroke 70hp Yamaha outboard provide enough power to support the charging of 2 batteries simultaneously?

The way the relay works is that it senses the voltage of your starting battery and when it reaches a certain level it switches over to charge your house battery. That way only one battery is being charged at any given time unless you have the switch in the combine position. I would not recommend operating in combine mode as it is intended to assist with starting should your starting battery die. Doing so may damage your stator. If your outboard is equipped with a charging circuit this should work just fine. Being a 70hp I'm sure it is.

Yes this will work. You will need a solar panel that will recharge the battery draw (you can calculate this from the watt output of different panels) and a battery large enough to provide the current draw without getting below 10.5 before it gets recharged by the panel. You also would want a marine style deep cycle or at least a start/deep cycle combo battery. Remember that solar panels and batteries are not 100% efficient so calculate the load accordingly. All that said I do just this on my boat along with running additional DC loads and don't need to run my aux engine to recharge the hose bank while at anchor. Yes this will work.

Hi, I'm sure you can but, it has to be plugged into a 120Volt supply when charging the batteries. When the boat is on a trailer parked somewhere it would work great.

This is not a deep cycle battery. It runs my lawn equipment with no problem but I seriously doubt if you could run an outboard motor with it. it would start it but that's about it. Good luck.

I am sure it would. I bought it for an electric trolling motor because it is designed to be recharged frequently without harming the integrity of the battery. My Son and his girl friend used it on our canoe last weekend and went for some distance solely on the motor. No paddling. It will certainly turn over an outboard.

I use this solar panel to charge two 12V batteries connected in series to produce 24V. my boat has two 12V batteries, but they are connected in parallel which is likely the case for your boat. Also, I believe that you should be looking for a 12V Solar panel, not 24V. Hope this helps.

I agree with Hugh & Dean. This Charger charges and monitors each of two batteries independently, so yes, one could be your starting battery and the other battery could be for accessories or trolling motor.

Yes. I have this mounted on my boat dock to charge a 12 v Battery for my boat lift. Working perfectly.

Hi ThereI run the inverter off of a 27D size 12 volt battery on my boat that is charged from a 120 amp alternator off of the motor.

I'm just an end user but I don't think it would put out enough juice for two amps. Worked great on my factory Harley stereo. The case was too big so I just used the board and wires (oversized case).

Yes, I have mine attached to my battery in my boat 24/7 (at least in the summer) and use the boat at the same time. Don't expect this charger to come anywhere close to charging your battery while using the trolling motor tho. Connect it and forget it.

The boat I use has a 12 volt battery, the outboard motor has an alternator that keeps it charged.

Yes. This charger works 3 batteries. For my setup, I have for my boat a marine cranking battery. Then I have 2 full deep cycle batteries for a 24 volt trolling motor system. I used to charge them one at a time which was a major pain. Plus I never realized that with the primary cranking battery, running the battery off the alternator once running will not fully charge the battery. It will only get to about 70 percent full. However with this battery charger, it has an internal computer which will properly charge and maintain the battery. The other good thing about this charger is that if you only have 2 batteries, you can still use it. Just pair the other free connections to one of the batteries. I contacted ProMariner customer support directly and they confirmed this is possible and safe. Overall happy with the product!

I use mine with a Marine deep cycle car battery to power lights and a tablet as a portfolio at an art fair, so yes it'll do the trick.

I have used this battery to power a similar trolling motor on a Native Watercraft Ultimate 16 with 2 adults for 2 consecutive days. I do not know how much power was left so I recharged before the third day. This was not constant use, but it was a significant amount of time running on speed levels 3 and 4 of a 5 speed motor. I have done this several times in both river and bay applications. Hope this helps.

I have 2 sets on my pontoon and am adding 2 more I will definetly run a secon battery, but if you put a switch on them and use them for 2 or 3 hours, you could probably get by with one battery, hope this didn't muddy the issue to much . It's always nice to have a extra battery on board, in case your starter battery decides to belly up. Good luck and enjoy !
