Mates: Lets keep sight of the original thread question being asked by a potential buyer, which was, is the 11HP engine adequate for a C30.Here's a hypothetical question you have to ask yourself - if you had a engine less catalina 30 weighting well over 10,000 lbs fully loaded and you were considering repowering with an OB, would you consider an 11 HP OB as your choice of power? The question answers itself. So if your choice is between and 11 HP and a 23HP only a fool would buy or even suggest you buy the 11HP. Additionally, your resale value on the 11 HP takes a dump as soon as you sign the papers and when you go to sell the boat your stuck with something a well informed future buyer doesn't want, unless he just got into sailing yesterday or last night. Catalina quickly realized their mistake and stopped installing that engine. Why would you want to compound their mistake?To answer Larry W question about how often my boat goes out - when your working 6 days a week, racing Wed night and Saturday, conducting sail trim seminars, have a motor home and property in AZ, sadly it doesn't leave a lot of time for sailing my C30. I wish I could find more time to sail my own boat but so many other things seem to get in the way - one of which is trying to make a few bucks to survive. Not having enough time to use my boat is one of the reasons my boat is now FOR SALE. On the other hand, if I was sitting on my rear end and unemployed, I'd have a lot of time to devote to sailing.
