I have what i think is a early 90s mercury 50hp 3cylinder 2 stroke. Idles perfect and runs great to probably half throttle then thats all it has. It wont go past half throttle. I cleaned the carbs, the oil injection isnt working properly. so ive been mixing the fuel 50:1 the oil injection isnt bypassed yet because i havent been able to find the correct kit. The spark plugs look oil fouled even though it doesnt really smoke running. It free revs in netrual to full rpm but all the threads i read just didnt seem to fit my exact problem. If anyone could give me some ideas on what to check it would be greatly appreciated im tired of being stuck going 8mph makes for a long trip lol. Im leaning towards the oil injection and mixed fuel causing my problems but im unsure since i cant find the block off kit. (Will get model number and compression numbers after work) thanks you in advance any help would be greatly appreciated!
