Welcome to the 23 club
May I suggest a excellent book for the small boat owner. "Sailing Big on a Small Boat" by Jerry Cardwell. I have read and reviewed this book so much, that it is now held together with scotch tape. plus some duct tape too. Get it!If your boat is a 23, you can run up to a 15HP two stroke engine. Older Johnson or Evinrude 9.9s are actually 15 HP engines with smaller carbs created to be used on lakes that had an under 10HP restriction. You can run your boat at hull speed at half throttle. If you need more power, and you will, you will have it. Another tip from the book, was cushion replacement, 4 inch minimum thickness. Foam also comes in differnt densities. You will notice a big diffence within a few months of use. I had the new foam cut using the old cushions as a pattern. Then, as suggested by Mike, went to a auto upholstery shop to aquire the material plus sewing. I saved over 50% on my orginal quote. Happy Boat Ownership! Jack
