In my case it left a lot of what looked like salt& pepper colored sand like debris with a white corrosion like dry scum on the bottom & sides of the bowl. Took a long time to get the carb cleaned out.

Later, I did a test on an old carb I had, filling the bowl with gas treated with Berrymans B-12 fuel additive. Took it apart about a month or so later and the inside of the bowl was perfectly clean. No sign there was ever any gas in it at all.

It may depend on different “ batches of gas? In any event, the minute or two spent on draining the carb is a whole lot less than 2 hours, or so, removing & cleaning a dirty carb.

“Reflective tape”, good idea.

When you remove and clean your carb?

1. Are you talking about a 4 stroke carb?
2. Besides a can of carb cleaner and a screwdriver what do you need?
3. Are any parts automatically damaged by taking it apart, like gaskets for example.
4. What parts may be reused sometimes but should be replaced.

Yes, although I have also done many 2 stroke & automotive carbs

I have an air compressor which I use before the spray cleaner. A large, clean towel to put the parts on, lined up in sequential order, with "Up " sides "Up". Screwdrivers that "fit" are helpful, as is thin wire, like trolling wire.

I have been lucky in re-using what was there, by being very careful in dis-assembly. However, that being said, I think that buying a carb "repair" kit:

Tohatsu Repair Kits

would be best. IIRC, some automotive carbs have "check" valves which are spring loaded small steel balls, which can fall out in dis-assembly. A good parts diagram would be helpful. I think they can be down loaded?

Overall, suggest you go slowly,& very carefully. Pictures along the way may be helpful. As mentioned, line up parts from left to right in order of dis-assembly, with the "up side" up. Re-assemble in reverse order.

Cleaning may not always work. I loaned my 2HP Honda to my son in law. He didn't drain the carb. I attempted to clean the carb twice but could never get the motor to run spot on again. One new $100 carb did the job, it ran perfectly.

Re: Maintaining an outboard

The following is my final inventory so far.

Two bottles of stabil
bottle of seafoam
two bottles of motor oil
one tube of lower unit oil.
One tube of grease
Fogging Oil
Impeller
Spark plug (came with boat)
Emergency starting cord (came with boat)
Wax
Zinc
Fuel filter
Manual
Carburetor

The only thing I can think of left would be:
Propeller
Carburetor repair kit


Other than rags, screwdrivers that I should have anyway is their anything else?

I donít know how much time you plan on putting on the motor or where? However, unless you are going to be running it long & hard your list of things should be good for a long time. Based on my own experience, feed it a plug once a year, change the oil when it gets dirty or dark, change the gear oil every couple of years and donít run it in the sand or out of the water & the impeller should last for many years

I had an Evinrude 35 HP on my fishing boat, used heavily & often in salt water for well over 20 years. It finally would not cool properly at very slow trolling speeds. A new impeller fixed the problem. Starting it dry occasionally to make sure it would fire probably didnít help. That was the only impeller in the 10 outboards I have owned to need the impeller changed. Donít run it out of the water.

Anyway, looks like you have it covered & then some. If you drain the carb & use a good fuel additive, based on my experience, you should not have any fuel related problems.

Spray degreaser, perhaps a spare fuel line squeeze bulb, certainly a handful of small hose clamps for the fuel line.

If you have a propeller with a rubber hub carry a spare. If your prop uses a key carry a couple of those.

Re: Maintaining an outboard

Not sure how much work you plan on doing "in the field", or "on the beach", but changing the impeller can be a bit of a chore. If I ever have to change another one, I plan on turning the motor upside down so I can better see what I am doing. As well, taking the carb apart in the cockpit would not be my favorite thing to do. If you are going to be in a remote area, the spare prop, which does have a rubber core, is a good idea. Carry a socket to fit the nut, & stout long nose pliers or diagonal cutters to get the old cotter pin out, & new cotter pin(s) for re-assembly.

Sounds like you like to be prepared, which is a good thing, especially if you are going to be "way out there".

Thanks for the ideas.

At this time my idea of way out their is a 15 minute drive to West Marine.

But even so if I'm depending on something and I know I will need a part eventually and their is no guarantee their will not be some one-in-an-era shortage when I need to get a part I figure I might as well buy it and have it on the shelf.

Well, I think Tohatsu has been around for a long time & being a major supplier of small & large outboards, parts should probably not be a problem. We have had our 6HP 4 stroke Tohatsu for two years, use it a lot, with no problems. The only thing is it is a bit fussy about how I start it. The starting instructions have to be followed to a "T". Perhaps being at 6,000 feet elevation with no jetting changes makes it a bit fussy. Otherwise, it runs perfectly, hope you enjoy yours.

I am a huge Honda fan but their 5 HP weighed a bit more than the Tohatsu 6HP.

The parts for my 1982 tohasu 8 hp 2 stroke are no longer available have to go to a bearing and seal shop with mikes to find replacements
