I have this motor in one of my boats, its a echo motor from a Mantis tiller

the motor runs smooth and seems like with the quality of the motor is should be a faster than it is.
just wondering if it was factory toned down for emission reasons and if any one had some tips for it.

thanks

I have a Tiller with a Hommie motor and it seems to be tuned to work the best on the tiller not needing the rpm of a trimmer so I don't think it would work in a boat very well.

All weedy engines are somewhat detuned for what we want to use them for, you will be surprised at the performance difference between a stock weedy motor and a properly modified one.
Theres always power there waiting to be released.

That is why I was looking for some tips. it look like it has some potential and I got it for free so I am not afraid to tear into it. just dont know where to start

Have never played with the Echo motor myself, Im sure some of the older racers would have run them at some time.
Hopefully someone will chime in.
First thing would be to get it breathing better (bigger carby/free flowing muffler or tuned pipe)
Next step will be changing the port timing.

thanks I will do some searches on that
