Tohatsu Reviews?

I tried searching, if there are reviews on Tohatsu outboards, please share a link.

What do Tohatsu owners think about their engines? How long have you owned them? Anyone have experience with a 6hp single cylinder extra long shaft? They can be had online for $1500, this is considerably cheaper than a 20" 5hp merc from my local dealer.

So what do you think?

Re: Tohatsu Reviews?

I owned an 18hp tohatsu, electric start, for about 6 or 7 years, which made it about 10 years old, when I traded it in. Started every time. Ran very quiet. I changed the oil twice per year and the plugs about every other year. Never had any major maintenance failure. I ran it dry and stored it outdoors each winter (which is not ideal).

The shop told me that one of the cylinders was losing compression, but you would have never known.

Anecdotally, I see a ton of tohatsu OBs on charter boats, which would suggest they are a good value and reliable. They are not top of the market, which I think is reserved for Yamaha.

As for buying a used OB, it can be a real crap shoot. You can't know how it was cared for, let alone broken in. Many don't realize they really need to full full power for the first hour or so, to set the rings. If that wasn't done properly, you can never recover.

Re: Tohatsu Reviews?

I have a Nissan 6, which is the same motor as the Tohatsu. The fuel economy is amazing. It uses about 1/3 gal hr., maybe a little less. It's a single cylinder, so it's not as smooth sounding as a 2 cylinder, but it starts and runs reliably, usually one pull. I got it used, and thought about replacing it, but had a couple minor adjustments made, and everything's fine now. I love it!

Re: Tohatsu Reviews?

Tohatsu makes a number of the various 'brands' in the 4-8 HP range, IIRC.

Re: Tohatsu Reviews?

I have seen many reports online that Tohatsu manufactures Mercury's small engines, up to 6 hp. The people who said it sounded like they knew what they were talking about.

Re: Tohatsu Reviews?

Mercury, Nissan, Tohatsu and possibly others are all from the Tohatsu plant.. in the smaller HP ranges. Interestingly Nissan offered double the warranty than the others.

Re: Tohatsu Reviews?

Tohatsu's are VERY reliable, especially if you use only 'fresh' gasoline, ethanol free gasoline; or if not, then 'religiously' used with a stabilizer formulated for ethanolated gasoline. Otherwise drain/discard the fuel after 60 days. This will insure quite trouble free operation.

The downside to most all recent small HP Outboards is the inability to adjust the air/fuel mixture in order to compensate for gum/varnish formation in the 'fixed' carburetors. There is a 'fix' for this but not appropriate for discussion within the USA.
Clean fresh fuel is a 'must'.
Consider to run the carb 'dry' before moderate term storage (a few weeks), also drain the carburetor bowl for long term (winter) storage and then flushing (then immediately draining) the carburetor bowl with isopropyl alcohol - IPA.
Replacement of the cooling water impeller is a real complicated PITA - typical of Japanese engineering; but, you'll quickly learn 'the trick' to realign the 'linkage' inside the shaft housing after a few times of changeout.
This engine will instantaneously destroy its impeller if run 'dry' for only a 'few seconds'.

With the 6HP, a standard 9-10 ft. inflatable dinghy with a 200lb. single passenger will easily plane with the standard pitch prop. If you need to carry more load or another passenger, consider reducing the prop pitch; but, then be VERY careful of not exceeding max. rpm when 'single handing'.

Indeed Tohatsu is the manufacture of the 'power heads' for many outboard brands. Some other brands are simply 'full' Tohatsu OBs with different 'cosmetics' and private label brand names, etc.

Good and quite reliable outboard engines; but, 'heavy' ... at about 57 lbs.

I just re-read his post out loud using 'air-quotes' with my fingers where appropriate.

Re: Tohatsu Reviews?

I have a 6 hp Tohatsu extra long. I've not had it long and only used it last season. I only use ethanol free gas in it along with a double dose of Blue Marine Stabil. Lots of power. pushed my little 1500 lb sail boat pulling a 10 ft beamy dinghy through chop and 15 mph wind AND AGAINST THE TIDE at 4.2 knots using only 1/3 throttle. nOT AN ISSUE. Great little engine.

Sat on the mooring for two weeks, and a tropical storm. Started right up.
