So after continual problems with my 1976 25 hp johnson.. We rebuilt the carb, new plugs, new tank and lines... It will run good, but once it warms up the plugs foul and it will not start.. I decided to upgrade.. I found a nice 2010 model short shaft 15hp for sale for $1400. Hmm.. Tohatsu?? I had never heard of them.. So I did a little research,, turns out they make the Nissan and the mercury in the smaller 4 stroke models and are the biggest outboard manufacturers in the world. Not to mention I could hardly find a bad review, so I bought it. This motor actually weighs 30 lbs more than my old 25 horse! So we beefed up my transom, using some 1/2" threaded rod and steel plates, set up a Transom Saver attached to my trailer for stable travel and let me tell you this motor is a thing of beauty. My boat plains out so nice and fast..It runs so quiet and smooth, the top speed is up to 21 mph, 1 mph more than my 25, but where it really shines is torque and fuel efficiency. Fully Loaded with 3 anglers and gear I still did 13 mph and I think I gets twice to 3 times the fuel mileage as my old 2 stroke and no mixing oil every fill up either! Other great features of this motor are an easily visible water fountain so you know the lower unit is working, and an oil light and a steering tension control and a shallow water run mode.
