Got one on my 2011 36. Don't use it much, but its useful if its a bit blowy and you have a tight, slow to get into berth. Go for plenty of power, so if you do need it and you are having to push the bow against a current or something, you have sufficient drive. I had a boat once with an undersized one and it was rubbish because the few times you did need it, it could not cope! As has been said, go for short power cables from a dedicated batt. Make sure batt is sealed type and properly vented. Put control on the binic if you can.
