     30 foot party hut, fishing off the back, which is a raised deck about 5 feet off the water. No back door access to water. I have no front deck to fish off of. Here's the rub.
      Not really wanting to spend the money for a kicker motor and steering rod that runs off the out-drive,,,pricey. Don't mind a kicker off the back but can't figure a way to steer it or work the throttle from up on the deck.
     Thought about a electric trolling motor off the bow, would need to modify the front gate and then I am limiting my time to the size batteries I run. With a 30 foot boat that acts like a huge wind-sail, I'm thinking at least a 75 lb thrust motor is minimum,,, and two or three big batteries. That's allot of weight to carry on the bow. Not sure if it's smart to run long/big battery cables to the rear to re-locate the batteries? What say you?
      Then there are the electric motors you mount on the outdrive. Good but the weight of the batteries comes up again.
     So I been thinking of just getting a "Happy Troller" plate and using the main motor to troll. But this sounds like a waist of gas and allot of wear and tear on the main engine. Is that silly??
     Too many options and looking for advice from you guys,,,,, thanks, sorry it's a bit long winded!!!

Well, one of the beauties of your rig is that it's an I/O.. and that basically means that you have a car/truck engine in the thing.  It will happily and smoothly run at near-idle speeds all day without a whimper, and is pretty reasonable on gas when it is doing so.  So I personally think that the trolling plate is probably the way to go.

If you really have your heart set on a trolling motor, the PH can handle the extra battery weight no problem, but I agree that you'd probably want to locate them toward the stern.  If the trolling motor is mounted on the bow (you might want to consider adding an anchor platform like I have on mine)... then you'd have to run some decent sized copper to the front.  But, a 24V 75lb thrust trolling motor isn't really a current hog and the wire gauge wouldn't be outrageous (unlike a 12V setup).  I'd have to pencil whip the numbers to get the actual gauge value though.  Then, of course, you'll need to add a charger for the deep cycle batteries.. and then figure out how you're going to get power to that charger.  Shore power?  Or are you going to trailer the boat every time you use it and charge the batteries when you get home?

Will be taking it home to charge it. I'm only 8 miles from the ramp Big smile. The new i-pilot ( I think that's what it's called) from Minn-kota would be nice. Holds you in one spot for rock fishing and can repeat the same run if you like or set a course and stay on it ,,,, all by gps. My wife like the idea of no noise from the main engine. But I agree with you. That motor should last my lifetime and the cost of the other alternatives would buy allot of gas !!! Thanks for the info. I had not thought of the higher voltage systems using smaller wire. I could even put the batteries mid ship and be pretty balanced.

One other comment:  as you have already noted, the PH is a big sail (not as bad as my PC, but still pretty bad).  A 75lb trolling motor isn't going to stand a chance if you are dealing with any kind of wind at all.  I use 80lb units for my bow and stern thrusters.  Yeah, they'll move it, but not really fast and only when they are running full-tilt, balls-to-the-wall.

I have a 74 lb thrust trolling motor on my boat. At wide open it will pull my 24 ft around at about 2.5 mph (GPS) 

I bought mine used and need to get a part so I can use the speed control on mine but it does pretty good. 

The newer ones go over 100 lbs. I think the bigger the better on these if you can afford to do so. 


36v is how some are setup now too I believe
