50hp+
To amplify another post, yes sailing venue should be your first consideration, you don't need a lot of horsepower on a small lake.Now, on the other hand, if you are on a huge lake as in the Great Lakes or coastal sailing in the ocean then don't stop at 50hp, the Evinrude E-tec 50hp and 60 hp are the same engine, just that the 50 is de-tuned to put out less hp, go with the 60hp E-tec and you won't regret it. Recent rumors indicate that the factory recommended engine will in fact be the E-tec 50-60 engine. So there you have it. Now if you have some extra cash, consider the Etec 90hp, and you will definitely experience the true duality of the Macgregor powersailer and enjoy planing in the true sense of the word. I have 50HP Honda on mine and that poor engine screams its' guts out at WOT without quite making it up out of the hole and planing on its' bow wave. The Etec-60 might be the ticket to planing and if I was buying my first engine I would settle for nothing less. I sail in the PNW and regularly challenge tidal currents, sure the Honda works but it really struggles under load. My next engine will be an E-tec 90hp, just have to save up some cash. I know of several Mac owners who have upgraded to 75hp, 90hp and beyond with no regrets, the more hp the merrier. Also consider more hp extends the reach of your sailing grounds and on extended trips you can cover more miles per day. Advantages of more hp far outweigh the added weight especially with the better hp to weight ratio of the E-tec series. As for a 40hp, a great big mistake, don't do it, you will live to regret it.
