Sorry for the delay in getting you this info. We just moved and things have been hectic.
Here is a link for the winch Llowell used.
http://www.dutton-lainson.com/mfg/electricwinchespage.htmlIt is the SA model and he took the fiberglass housing off so that it would fit under the step. He also mentioned that he felt that the pulley for the cable needed to be beefed up. On his boat he had noticed that the fiberglass underneath flexed and added an aluminum plate underneath for extra support. I have not found this to be an issue on my boat. I also know that he marked his cable so that he did not snap the cable by raising it beyond it's capacity. Llowell is and engineer and seems to have done an excellent job with his installation.
I also need to replace my winch, not sure if I will go electric or not. Let us know how things work out.
