Hi all,<br />I'm planning to attach an Endura 36 transom mount trolling motor on my searay 180. I plan to attached it to the boat's main battery. I'm just curious if that's OK and how often I have to start the boat motor to charge the battery if I plan to run the trolling more for say five or six hours. I'm just concern that the main battery might die on me. Also, are there any concerns with the trolling motor disrupting the electrical system in the boat. Any advice would be greatly appreciated.<br /><br />Thanks.
<br /><br />But really I don't know of anybody that does that - most everbody gets a separate deep-cycle for the T/M. I just started using two 12v in parallel to get enough power for all day. You'd want to monitor it closely until you get accustomed to how fast it drains. My guess is, not more than an hour, hour and a half between high-speed runs with the main engine (depends on your alternator characteristics, and how much juice it takes to crank the motor - small outboard takes way less than a big inboard). But bring a voltmeter & check it more frequently 1st time out; probably need to keep it up around 12+ volts for cranking. Might want to practice pull-starting your big motor just in case.
