Above was in reference to the the question some time ago about the zinc. In a more general review of the Tohatsu/Nissan/Merc 6 HP I will say that they seem to have really small jets and I am having trouble keeping the motor running more than 4 weeks. I started the season with new gas after having had the engine serviced for trouble last season. I treated with Stabil Marine and within 4 weeks the carb was clogged with white mush. I cleaned it a few times and used Sea Foam. It started running again but 4 weeks later it was so clogged that I took it to a marina along with the line and the tank. They pronounced my gas fine, cleaned the carb and now 4 weeks later the carb bowl has white mush in it again and the motor wan't run. The marina talked me out of using aviation 100 low lead saying it would clog the rings but if I get that thing going I'm switching to ave gas and if that fails I'll sell that and move on. Which which other motors fit because I've had enough of this one? I didn't have much time to use it so basically this ruined the season. I've had guests waiting on board the last few times which we aborted when the motor wouldn't run. Basically we can't make a motor on its third season run more than occasionally. I'm going to take the carb off the old tohatsu with the ruined lower unit and try to make it to the marina to pull out for the season. AAAGH!
