I have a 1992 Evinrude 200xp model e200stlens and would like to find out what year model powerhead will interchange with it? I was told by one powerhead exchange company that it is a one year only block. I have seen numerous 25” shaft motors for sale at reasonable prices and curious if any of them will bolt on to my midsection or if I should just part mine out and start over. I bought this boat several months ago and have yet to get it running right. It cranks up and idles great and when I finally get it to plane out it will run great but getting it up on plane is a bear. I’ve tried different props, new plugs,tested the coils, tried different height setups, cleaned the carbs, and fresh fuel. The boat I have is a 1992 Stratos 201 pro xl. It’s been well cared for and it shows by the condition it’s in. I forgot to mention the compression is almost identical in all cylinders. The way the motor sounds when trying to come out of the hole is an erratic misfire or “flutter” is the only way I can describe it. I can keep fighting with it and sometimes it go ahead and torque up and go. I’ve had several boats over the years and this is a first for me. Any input on this would be much appreciated. I purchased an evenrude service Manuel for this motor but there is little information about this issue.
