Mercunissahatsu?
Wow, that's a mouthful... I agree with Justin (and everyone else) that these are great little engines, though- I have 2 that have served me very well after MUCH hard use and abuse. One is a Nissan 5HP long shaft, circa 1986, and it still starts on the second or third pull... I've had a LOT of work done to it in the last year, but the previous 12 years saw LOTS of neglect for that motor- from me and the previous owners. I was amazed it ran when I bought it (came with my 23), but it has been a real champ right up 'til this season. Last season saw a water pump failure, which led to other problems... This season it's carburetor problems (only runs right with the choke half out!) but for a 14-year-old outboard that has been verily abused, I'm quite happy! I also have a Tohatsu 3.5 (Similar to the one that was 'dropped to the bottom of the bay' in a previous post), about 6 years old. VERY reliable motor, as long as it gets Premium Grade fuel (92 octane or better) from a good source. Mine seems a little over-sensitive to dirty fuel, but if that's the worst of its demands, I'll gladly pay for good gas! My only gripe with the Mercunissahatsu series is finding a mechanic- There's exactly one mechanic in Key West who is certified for them, and can get OEM parts, and he doesn't come cheap...--Jon BastienH23/H25
