which kicker for my Newtauk?

I've narrowed it down between a Merc 4-stroke 4 hp or a 2-stroke 5 hp engine. The main differences, with the exception of the obvious, is the fuel tanks. The 4-stroke has an interal while the 2 stroke has an external. Since it looks like I'll be using a seperate fuel tank for either engine, which one is the better engine? I plan on using it for trolling and a back up just in case my main engine decides to crap out on me. I like the idea of the 4-stroke but I wonder if I'd rather have the extra push when if things get rough, but the 4-stroke is also about 12 pounds heavier. Any comments? These engines were about the same in price and I'm looking for other points of view.
I've read the post concerning the 3.3hp. I'll assuming the performance would be similar for either engine.
Thanks for the comments.

I would probably go with the 4hp 4-stroke for a couple of different reasons:
1) The difference of 1hp is very minimal with a boat of your size. The 5hp will not really produce noticable difference over the 4hp, maybe 1/2 knot difference.
2) The internal tank is a very nice feature because it removes the feed line and the tank (a extra spare tank can be stored just about anywhere).
3) The 4-stroke will be more efficient and run much cleaner for long periods of trolling and be quieter.
4) The 4-stroke will probably be more reliable over its life.
Personally I would prefer a Yamaha 4hp, 6hp, 8hp or 9.9hp. But to each their own...

Thanks for the input and food for thought. I did decide to go with the 4-stroke but will be getting the 5hp. With the 5hp, I can tap into the main tank without a problem, weighs the same as the 4, and will have a little extra power if I ever decide to pick up a small john boat along the way.

Why not go up to the merc 4 stoke 6 hp, it the same motor only about $200 bucks more and you can get that back in resale. Plus it never hurts to have extra power in reserve for those windy days, my .02cents

I'm using a Yamaha T8 hi-thrust 8hp 4 stroke and love it. Went 4 stroke for kicker for reasons already mentioned. Long trolling with no smoke, fouling etc. T8 is 2 cylinder & VERY smooth at any RPM.
Other reason I went for 4S was fuel delivery. I've rigged it to feed from the same tank as main Yamaha 90 engine thru a fuel/water seperator filter. Each engine has its own primer bulb, fuel shut off valve and removable fuel line so both can be fed from a second spare fuel tank if needed.
