I have a 90 hp 2 stroke Tohatsu on my 17 Hourston and love it. Bought it new about 7 years ago. It has been an excellent motor for us. Lots of power and has been very reliable. I suspect the corrosion resistance on some of the external components will prove to be perhaps not as good as others over time, but I’m very happy with it. Japanese engineering and manufacturing at a significantly lower cost.
The only issue now, for me, is that Otter Marine (from whom I bought it and who did my initial warranty service) is now closed. I don’t know who would provide service in the lower mainland if/when I have a problem I can’t deal with myself.
