im planning on buying an electric trolling motor and i have heard it is possible to charge that battery as well as my out board battery while running the outboard with an isolater. what im wondering is how long would the outboard have to run to charge it? the outboard is a 85 hp force. also does any body have a better idea on how to keep your trolling motor battery charged while your camping away from power source?

Solar charging or as I do . I use a good set of jumper cables and charge it off my truck. I found out it is quicker that way.

Re: charging two batterys off outboard

I was going to just post same topic. I use an outboard with 11 amp max charging system, But!! I have found so far even leaving it idling while drifting and my normal use will not keep my battery charged enough to use electric trolling motor( to my liking). Am using a 1 battery system for everything. So everything ends up dead, even fish locator goes out till restart 40 horse with pull start. I do not want more batteries, extra kicker motor, all adds weight and more things to trip over.<br /> I invested inna a adjustable drift sock. My back trolling is 1.5 mph at idle but want about .5 mph for trolling. <br /> I considered calling nissan outboard to inquire about a high output charging system. Possible cheap resolution instead of adding more batteries/weight/ things to trip over.<br /> I understand the desire to have a self contained boat not needing plug in's. My boat sits in storage or several days out an about where cords carring batteries seems counter productive to relaxing.

Re: charging two batterys off outboard

My estimates for my setup is about 2 hours run time on outboard gives me 20 minutes electric trolling motor time. Yours maybe better as to larger motor and larger charging capacities (didnt wanna discourage you) Will check back hoping to learn more on this topic, I'm hoping to accomplish same objective as you!! I posted a few days back about solar panels. Not a realistic option to real power.
