I have what appears to be a early 90s Mercury 25hp long shaft tiller. I am selling it as a parts motor as it currently does not run. A quick diagnostics has found it doesn't have spark. I disconnected both stop switches in the hopes one was bad and that did not fix it. Both cylinders have 120psi compression. There is no water in the gearcase. It is missing some carburetor linkage, and the shallow water drive parts on the midsection are missing. I quickly went through the carburetor and it was clean. I do have the cowling. I don't have time for it. Come and get it!!!
