I have read all of the posts here regarding Tohatsu motors and am about to purchase a Tohatsu 40 two-stroke to repower my 1983 Sport 13. Has anyone repowered with this motor, specifically jshell? Any thoughts? Thanks.

I still haven't heard one. The dealer seemed to think I was a pain for asking to hear one run before I walked away.

I had excellent results with a 70 Tohatsu, a 1993 model, which I sold when I replaced my Tashmoo with a Montauk. Seven seasons without a hiccup.

There are four small boats at my dock and two of the boats,including an ancient 17 are powered with Tohatsus. The latter has a TLDI 90 and the owner is very pleased. This is hardly scientific feedback, but I hope it helps you decide.

I had a 1995 40hp 3 cylinder on my 1962 13'. Ran like a top. Very smooth idle and always cranked right up. I don't think it is as powerfull/fast as a merc or rude...but 40mph in a 13' was plenty for me. I wouldn't hesitate having another on the transom.

Sport 13,

I actually ended up selling my '78 13 and bought a barely touched 2001 13 Sport w/ a 40 Mercury. It ended up costing me only $500 more to buy the 2001 than to restore the 1978 and put a new motor on it.

I am very happy with my purchase, but there is a good bit of me that wishes I had restored the classic. I am sure I will end up buying another one to restore.

Anyway, I talked to a lot of folks about the Tohatsu 40 and never heard a negative thing about them. No, they do not have the high end speed that the Mercury has, but I gathered that they would crank up everytime you turn the key. Getting home every time is more important to me than going 40 mph. My buddy has a smaller one on his duck boat. We have run that engine through the weeds and mud of the Mobile delta for five years now and it has never hesitated to crank.

If I hadn't bought the new 13', I would have bought the Tohatsu 40. Plus, my Merc idles doesn't idle well. I know that some of these Mercs are known to idle rough, but it is still gets to me. Other than that it runs great.

I have never had one, but, for what its worth, I would have bought the Tohatsu.

Good luck,


P.S. I also heard that Tohatsu makes most all of the small and mid-range outboards sold in the US for Merc, Yamaha and others. Something to consider.

In practical terms all will come down to how good and personalized is the Tohatsu service and parts in your area and how soon could you have the motor maintained, prepared for storage and then re-commisioned when time comes.

Not long ago I read that a Yamaha two stroke could last 500 hours at wide open throttle, under load, non-stop between engine rebuild. These was state of the art circa 1990's and was included in the motor brochures given to service managers. Will other manufacturers such as Tohatsu publish such figures? This is a real consideration for me, but I do take care of my outboard.

Another consideration I would take into consideration is engine displacement. To me this is crucial if performance and long term reliability are high in your priority list.

I have a nissan 70, tohatsu in disguise, on my 16'7" nauset. Was purchased in 1998 in weesiana. I have owned it for two years and am very pleased with it. There are many service centers around and parts seem to be readily available even though I haven't needed anything more than a water pump impeller as Preventive maintenance. Engine looks and runs like new. If I had to repower I would strongly consider another Nissan along with Yamaha and Suzuki.

jshell, just a correction, Tohatsu does not make any engines for Yamaha, Merc, Evinrude, Johnson. They do make all of Nissons.

I had a 40 hp nissan on a 1965-13ft Whaler.
Other than being a little hard to start,
we never had a problem with it.

Backfire, take another look at the Merc 2.5, 3.5 2-strokes, and 4-6 hp 4-strokes. You are technically right though, they are not made by Tohatsu, as a matter of fact neither are Nissans. Tohatsu and Nissan are only brand names. All of the above mentioned engines are actually built by Marubeni Engine Corp. in Japan.
