I've made a simple stand out of timber for storing and flushing the motor in a large bucket/rubbish bin, something that you could easily take away with you. 

If water is limited you can always remove the prop and flush in a smaller bucket to save on water (and mess) just may need to use a new split pin when reinstalling the prop.

 

I'm playing with the various Viking Kayaks (I work for them so I get to call this Research and Development  )

We are probably going to stock them - if you are interested I can email you some info when I know more.

The Honda is a little heavier than the little Yamaha, but there are a number of features that make it appealing:

1. no flushing

2. twist throttle rather than a sliding throttle on the front

3. tiller arm swings over top of the motor for reverse and you still have throttle control

4. no flushing

5. at idle the prop doesn't turn (the Yammy prop continues to turn slowly so the kayak never stops unless you hit the kill switch)

6. no flushing

7. no oily smoke when idling along trolling live baits

Oh, and did I mention no flushing or water pump to maintain 

That was one of my decisions to go 2 stroke...weight, portability and cost...    

And no cheek from some of the watchers out there - I may be getting old but I'm still a paddler. It's just that motors are cool too, especially when it means spray in yer face  

Just thought id throw my 2 cents worth in FT.  I agree with Dan and wouldn't class them as a kayak especially not being able to paddle them properly. I fitted a 2hp outboard to my kayak with the help of a outrigger setup a few years now ago so its probably something in between a kayak and what you are looking at. 

I did this because we fish some spots further out and with limited time instead of being knackered at the end of the day from paddling I can still do other things.

The biggest advantage I've found that it gives you scope to cover more ground quickly so you can access more fishing spots in the same amount of time, so in effect more time fishing and less time paddling.

You can tow someone out or in your case take an extra person with you.

It maintains good speed into wind and current compared to the kayak but i do get very wet when there's a bit of chop. the inflatable is probably better for this.

Set up time for me is only a few extra minutes fitting the outrigger and outboard. but it does add up when you are trying to get out quickly in the morning.

The biggest disadvantage I've found is the maintenance of the motor. Having to flush it out after each trip and and keeping it in good running order. I have been caught out a couple of times earlier on and now I am pretty particular with everything about it (keeping the carb clean from salt deposits and checking the plugs) This does take away a lot from the simplicity of kayak fishing.

I agree with Limitless see how they paddle in the case where your motor packs up especially when you are a long way from your launch spot. 

Lastly is the exercise/fitness aspect or lack of when you use a motor, something I regret a bit now. 

Hope this helps...
