2000 Tohatsu 5hp — design & reliability comparison?

[Cruisin97]

Any guidance on design & reliability of a 2000 model year Tohatsu 5hp 2-stroke vs comparable 2-strokes of the era?
Looking at one that is branded as a Johnson, but am unfamiliar with that vintage , power rating of Tohatsu.

All the stone age technology 1-cylinder 2-strokes will be similar. The government rates the HP, so no worries there.

If being a Tohatsu M5B in excellent shape go for it, it's a very nice one cylinder 2 stroke little motor used as a kicker or small main for certain boating applications along spare parts availability...

I have a 2001 5 hp Nissan that I had out yesterday and it's a great little engine. I like that the engine turns 180 degrees. Makes the boat very maneuverable and it's fun to make the boat spin inside its own length. Mine has the integral tank and just got a new tank because some gorilla overtightened the cap and tore the threads off the tank.

These motors were good enough that ( like their 3.5 hp little cousins) Tohastu made them for Mercury, Nissan and Mariner. ( Same basic motor, different paint). I've owned 4-5 of them over the years and still keep one . ( All 98' or lower though) IMHO, nothing (even today) beats them for power to weight ratio. 44#, F_N_R gear shift, internal tank option, easy starting and 2 stroke reliability. LOTS of torque too, ( My 5 hp Tohatsu 2 stroke, pushes my 14' pond skiff to the same 16 mph as my 2015 Tohatsu 6 hp 3 stroke) . BTW, Mine is never going to be for sale! p.s. If there is a down side to these motors it is that their little one lung power heads can idle a little rough.

Those small portables doesn't count with lower leg's double water intakes as found in larger HP models, just a small water strainer right under the AV plate, so will need to be fluhed ON with fresh water in a large bucket soon after returning to terra firme or...

order a flush adapter code # 336600070, remove the lower flush bolt located under the pan, install the adapter with hose and flush the motor ON or OFF for as long as you want. As this little motor doesn't count with a thermostat on the head will be able to flush all water passages nicely and if counting with high water pressure much better...

I took a dremel and took off all the rough edges I could get to in the manifold and intake port, she runs much smoother now. That little motor pushes my old 17' Grumman transom canoe up on plane. I'll never sell either one.
