I have a
Simrad WP30 that is 5 or 6 years old, and it is not quite up to handling my 21,000lb
boat. I'm not certain if the strain of trying to do so has done any damage to the unit - it still seems to operate/react, but my boat is just too much for it I think. (This is contrary to what I was told by the guy who
sold it to me!) It is designed for your size boat, for sure. I paid about $2000 for it, but you can have it on an "as is" basis for $500 because for sure I can't use it.
Email me back if you are interested.
