The LT-2 is a great boat for kids. I've had one for 20 years and it is still in pretty good shape. I keep it in a cockpit
locker so it doesn't get UV.
We have a larger RIB
that we tow but my four kids all learned to row on the LT-2 tethered with long line that gave them confidence. The kids are probably more emotionally attached to the LT-2 than any of the boats we've had.
The Honda is pretty heavy for the LT-2. I've had one but never tried it on the LT-2. I used the smallest Tanaka (1.5 hp?) for years and it still runs okay too. I also have a very small Seagull that fits the boat well. You'll want the lightest motor
you can find and horsepower is not a factor since there's no way the boat can absorb enough power to plane. When young the kids were a bit scared of the motor
so rowing is totally acceptable.
My now-14 year old daughter still loves to row the LT-2 around. Since it's always in the locker it is always available even when we don't bring the larger RIB along. I'd definately replace it if it reached the end of it's life but that doesn't seem imminent at this point.
