Mercury/Tohatsu 6HP 4 Stroke Range and MPG Test

Testing a Mercury/Tohatsu (same motor) 6HP 4 stroke outboard Jon Boat motor on a Coleman Crawdad 12’ flat bottom Jon Boat. Can a Jon Boat go farther on a gallon of gas than a Nissan pickup?

I strive to make high quality jon boat, small outboard, and small stream fishing vids.

We will do a gas mileage and range test on Mercury/Tohatsu 6HP outboard jon boat motor to see how far we can go on a tank of gas and get this Mercury outboard’s MPG.

Will it be better than my Frontier Pickup Truck? Can a Jon Boat go farther on a gallon of gas than a Nissan pickup? Watch to see!

Fun fact: all Mercury/Tohatsu/Nissan outboards under 25HP are the same motor manufactured by Tohatsu Japan! Only under different branding!

Coleman Crawdad Jon Boat weight as loaded in the video: 379 lb. Length 12’

I got the external tank for my Tohatsu and I went camping at Shell Key on January, spent the entire day in the water and only used about 3 liters of gas. The tank is 3 gallons and came back with most it left over. Super efficient little motors

[SombraEnMovimiento]

I have two of these motors and i always run them dry after use. Sometimes i forget to pull the fuel connector off before i reach my destination. I then let them run dry on idle. I timed that, and it takes over 6 minutes! And then there is not much fuel in there. Only in the hoses, the fuel filter, the fuel pump and the carb bowl. It can idle on that little fuel for over 6 minutes!

Just bought a used boat with a 2006 Merc 6HP with no internal tank but a 6 gallon external. No wonder it had bad gas.

Just discovered your channel and so glad I did. I really enjoyed watching this video, you’re great on camera and have a great demeanor/ overall comfort in your vids with great info as well. Subbed!

Thanks for sharing / doing this test. I’m getting ready to do the same test this week with my 6 Hp and randomly was thinking…. Surely someone has done this before! I’ve owned several of these 6hp motors through the years and really must say they are worth their weight in gold. I have a Suzuki 6hp now and while it’s great, it doesn’t really compare to the Merc / Tohatsu. Cheers from Florida!

Dude sick video! I just recently bought a crawdad cheap and did a rehab similar to you! Send me your email and I’ll send pics I think you would be able to get some nice ideas from my mods! Thanks bro subbed!

What size boat is that? I’m wanting to put a 6hp on my 16 ft heavy boat (440lbs dry) just need to put put around faster than a trolling motor without dealing with batteries. Just setting and checking jug lines and limb lines not breaking any speed records. It’d be so much simpler to just put gas in the top and bring the whole motor in in winter. I wish I could buy a 9.9hp with self contained fuel tank. Thanks

[lancet.]

Thank you for this video! I am in the process of choosing a motor for my solo skiff and this was the motor I was leaning toward. I appreciate you making my research that much easier. Have a good one!

[Outdoors-pbsc]

What RPM were you running cause that plays a big factor in fuel efficiency.

[aarohivijh]

If you could post what throttle setting you used, and how long it ran for, that would help people with boats other than yours. Thank you.

[FishingwithGabriel]

How stable is that Jon boat? Can you stand up while on it? And do you know the weight capacity?

[timhudson]

I am so impressed with you'r videos.
We've talked about this 6hp you have
Im wanting to buy a tohatsu 6 for my alweld jon boat 14/36..

Bro I’m returning the 3 gallon external tank and fuel line I just bought. Fuck that lol

[cmatiazzoify]

I was watching all your videos and I am a proud owner of a Brand New 2022 Tohatsu 6 HP MFS6DWDS Outboard with the internal tank as well and I went ahead and bought a 3 Gal external as well, but just now I realized something, last time I watched this video I was under the impression that the internal tank had a 1 gal capacity and that with that, you could go 9 miles, so I was like, man If I buy a 3 gal external tank, I will be able to go 27 miles, but now watching your new video, I went to check the manual and realized it is a .3 Gallon tank and you can go 9 Miles??? LOL

[craigweis]

The 9.9 Merc 4 cycles have an accelerator pump, and each twist of the throttle floods the engine with a shot of gasoline. Don't flood the engine, with or without the engine running.

[bringonthesnow]

I have the same boat and tohatsu 4 to 6 hp conversion…. Only go 10 mph but have wood decking throughout and a 53lb trolling motor battery….. great setup…. Love my Coleman crawdad!

[prynceal]

Glad I discovered your content ...I think I am sold on then 6hp Mercury...I think it will be perfect for Native Titan 13.5.

[FishHeadsIV]

Where do I get the app for speed and distance?

[oneida]

Thanks for a fuel efficiency video. Nicely done.

[eddieknox]

try that on a metal jon boat, vs your plastic crawdad boat

[fleetwin]

Would have bet on the Frontier, pretty impressive
