I recently purchased a 1999 24' Harris Kayot Legend deck boat with a 1987 Evinrude 200. The boat needs a lot of work, but I've decided to make it my fall/winter project. The boat starts right up, and sounds good, but has no power at all. (There is no tach...its on the project list.). I did a compression test, and all cylinders are right around 105 psi. I also spark tested it, and they all show good fire. I have a few different questions. From reading, my next step is to pull and rebuild the carbs. (The boat sat up for over a year.) I find 2 different carb kits (398558 & 398557) depending on model (200 or 200 XP). That's the first problem. The motor has been painted, and I can't find a serial number anywhere on the mount. The number on the freeze plug (398-530) seems to suggest the power head has been replaced and doesn't give any information regarding model. (There is no model listed on the title.) Are there other indicators that will help me figure out the exact model? What is the difference between the carb kits? Will kit #18-7248 work on either model? I'm also wondering if I have power pack issues, but haven't found a good way to troubleshoot them. Everything I've read, suggests replacing them, and see if that solves the problem. I'd rather not throw parts at it, without knowing the problem. Is there a good way to troubleshoot power packs? If the power packs are bad, should I also replace the stator? Is there a good way to test a stator. Sorry for dragging this out...it's my first post. Thanks in advance.
