20hp Mercury vs 25hp Yamaha: An ENTIRELY NEW LEVEL of Portable Outboard Motors.

[@kustero]

Yamaha F25 EFI is still the best choice, if you are looking for reliability and a long lasting motor. My friends Yamaha F25 has over 5'000 HRS on it and runs perfectly. I am happy with mine too!

[@SkypowerwithKarl]

The only problem with the Yamaha is you may think the fuel gauge stoped working lol.

[@DCFloridasport]

Precisely, the mercs will always start having problems around 800-1000 hours and it goes downhill from there

[@kevincullinane2423]

Great input. I love Merc's. But I always have turned towards Yamaha. There quality, and reliability has always held up every time throughout the years.

[@cornbread6158]

A $3 billion division of Brunswick Corporation (NYSE: BC), Mercury provides engines, (who makes merc) Tohatsu Marine Corporation was set up in 1988 as joint venture with Brunswick Corporation, USA. Mercury Marine is a division of Brunswick Corporation and many of the smaller Mercury Outboards are just rebranded Tohatsu Engines. In addition, the entire line of Nissan outboards are rebranded Tohatsus.(who makes Tohatsus)

[@gunsandrotors8704]

Merc/tohatsu 20 hp 333cc block yamaha 25 hp 432cc i think and gears not the same merc 2.15. . yamaha is 2.00 or 2.08 gears merc 25 is 3 cyl. and 1.98 tohatsu 25 is a 3cyl. also same block as merc but 2.17 gears.

[@Trellah1]

Tohatsu and Merc 20s and 15s are both made by tohatsu. Same displacement (333cc), if you look at the side by side the power heads are the same as well as the lower unit. Absolutely nothing wrong with that, Tohatsus are some great little engines. Yamahas are a unique in-house design. Pretty much all engines out there 9.9 and under are all made by Tohatsu.

[@montyspearo]

Most of Mercury small motors are rebadged Tohatsu, sometimes Mercury change things eg tiller. Which you buy will depend on price, warranty, features and aftermarket support not that you will needed except for odd service.

[@johannwilder1437]

I can attest to the rattling sound. Just bought a 2021 Mercury 20 hp and it sounds identical. No other issues. Overall I love the motor but the rattle is annoying.

[@dustinpeak3884]

i have a 2001 15 hp 4 stroke and just found that the cover is what was vibrating. it had an adjustable bracket on it and took care of the noise. not sure if the new ones are the same ??

[@joewoodard2513]

I'm no professional but it sounds like you might need to push some of the weight towards the bow to get on plane easier. Love the content keep up the good work.

[@2631Fred]

Hi, according to my research on the topic of Mercury. Tohatsu manufactures Mercury motors from 40HP down to 2.2hp. up to 180 000 units for Mercury/year. The early Mercury FourStroke engines were originally manufactured jointly with Yamaha ; Mercury provided the block, crankcase, crankshaft and connecting rods, while Yamaha produced the cylinder heads for the 50hp. ... Both models were completed with mid-sections and gearcases. Mercury's agreement with Yamaha ended in March 2006.

[@richardcranium5839]

i have a 9.9 merc and a 9.9 tohatsu. tohatsu makes the base power heads. (block crank rods pistons cam head intake manifold) and there are variations from year to year and model to model. from there everthing else is just enough different you cant swap parts. i suspect many parts are made to different specs by tohatsu for mercury. and mercury makes some of their own. the ignition system carb and charging systems are completely different.

[@surjracer56]

I’ve got the 2020 merc 20hp on a 16.5 sylvan sea snapper. I’ve gotten 27mph with 2people and diy bass boat kit. Just installed an “on the fly jack plate” at the end of the summer only got to do one run with the jack plate on. Looking forward to next season nothing but snow now. Keep up the great vids.

How much you want for it

[@Fronk11]

I think you just convinced me to buy a CNC power tilt setup. I have a 2013 Merc 20hp on my 16ft SpringBok fishing boat. Would be nice to be able to tilt up for shallow weed beds/docks and to pull up the motor over night on the dock. I can obviously pull it up at the dock by hand, but its just a pain in the ass and I always imagine the motor cowell flying off one time as you need to use the handle on it to help pull up the motor.

[@stevesdaysoff2759]

Good video and very interesting. I have just go the Tohatsu 20hp 4 stroke outboard after a lot of research. The reason I chose the Tohatsu was it's reliability and weight of just 43kg compared to the yamaha 20hp at 56kg. Really enjoyed watching and subbed you. Atb Steve 👍

[@TinyBoatNation]

Thanks!

[@TTM-GEB]

Suzuki has a 20hp long shaft electric start and electric tilt that is 120 lbs.

[@storyman34]

I know you can't get them but I feel my 1996 Merc Sea Pro 30hp 2 stroke has so much torque. No problem getting up on plane without full throttle, almost feels like I could pull a skier up.

[@DCFloridasport]

On smaller engines always go Yamaha, Mercury has the high performance market sewn up of course from 450 and up but if I had to choose one brand it would always be Yamaha based on my decades of wrenching and boat ownership experience.

[@country_collector5209]

30 and under are made by tahotsu. Merc has props from 8-13 pitch a 9.5 p spitfire prop from Mercury probably work good for you

[@Dobe_Ninja39]

You should make kits on your website of all the electrical stuff ( like bus bars, fuse boxes, wires, battery charger)

[@klaymann888]

i bought a Yamaha 20hp 4 stroke on a 3.7 mtr tinnie off a mate , engines still brand new and not run in yet ... cant wait to test her out aye .

[@wojciechsmolarski6710]

Nice video. Thumbs up. My boat will be fiberglass 13,5 ft with a casting deck and trolling motor in the front. I really wanted that Yamaha, but finally I ordered Merc 20. Still Yamaha is heavier by around 10kg, so you can feel that already. So that was the main reason. Second thing, that in Poland there's over 1 thousand$ price difference between these 2 models. I agree 100% with that statement regarding weight to power ratio. If my boat would be 1 ft longer I would go with Yamaha.

[@robertbuffone5207]

I compared a 2 stroke 18 tohatsu to a 4 stroke 18 tohatsu on the same boat ,and got 1.5 mph faster with the 2 stroke, so I bought a 25 2 stroke Yamaha that pushed my 17 ft lowe bass boat with 2 guys, and all my equipment at 22.5 mph. I am happy, but the carbs have to be in sync, or it will pop and idle bad. It is a 2007 100 to 1 mix. Just changed oil seals on the bottom unit that were leaking. Over all it is a good motor.

[@Rlip]

Don’t run 100:1

[@roncolpo3731]

I would rum 50 to 1....your gonna burn that thing up

[@FlatlanderGear]

Going lower pitch and going faster isn’t weird at all. You bring the engine rpms up closer to where it makes it maximum power provided you aren’t past the WOT rom range.

[@montyspearo]

If considering changing to heavier motor, place few kgs in stern equivalent to weight difference and see how boat handles. Most importantly try it in moderate to heavy sea.

[@jjohnston6645]

Watch out for the new Tohatsu 25/30 coming out in August 22, 30 lbs lighter

[@MyersJ2Original]

Any chance youll be able to do the "same boat" compairison? I'm a bit less concerned with raw speed but more about fuel range. An extra $1 a day in gas is no biggie, but covering a large distance can be importan.

What's the TLDR for this video, which motor do you think is better if you had to pick between a Merc 20 and a Yamaha 20?

[@johnfrancis7176]

Thanks for the review. I am making plans to get a new fishing boat in the near future and I cant imagine needing a boat over 16'. My last boat was a 14' river jon, I feel the need to go up in size to fish two folks comfortably.

[@airlesscanvas2887]

my dad and I are both 5'10 (I'm 14 though) and we're pretty light I'm around 125 lbs and my dad is 140 lbs so a 12 ft Jon boat does the trick. my dad's 15 ft skiff can allow my dad and his 2 big friends (250 lbs and 350 lbs) pretty comfortably. just my dad and I is a joke lol

[@rbruce63]

How would any these motosr run on my 11' Boston Whaler Sport 11 short shaft with 4 people. My 1969 Chrysler 20HP seems taxed out with four people and cannot put the boat on plane with the 8-1/2" X 8-1/2" prop. However, It does well yet with two adults!

[@joshuawilliams194]

25hp Suzuki might be little heavier but it lot stronger than both of them. Its 3 cylinder instead of 2.

[@gjhtheunissen]

Take a 25 merc its also a 3cyl

[@noahjohns7954]

Suzuki is the best in my opinion before and especially after evinrude went out of business. Yamaha has the lightest 25 hp though, I’ll give them that. A 2 stroke 25 or 15 Yamaha is a workhorse though

[@countryfriedent]

Suzuki also has 4 valves per cylinder.. and battery-less EFI.

[@sethpurvis8680]

Tohatsu does make the small Mercury’s 30 hp and below compared my 2014 20 hp tohatsu to my uncles 2014 20 hp mercury they are the same motor with the exception of the gear shift in the tiller. I now have a 30 hp efi mercury and anytime I order parts I order tohatsu parts cuz they are cheaper than mercury parts most of the time. Saying that my old 20 hp tohatsu was tough as an anvil.

[@vivimu]

They used to...now merc 30 below are made in china not tohatsu japan

[@joej.4170]

Question: I am looking a the 20hp with electric start and power tilt (not power trim). My understanding is that it cannot be adjusted when your going full speed (the cylinder isn't strong enough). So its not really considered power trim. But you can adjust the angle of the motor at idle or low speeds. Is this correct?

[@stevenkunka8961]

The power tilt will not work while underway. If you try to ‘trim’ it at speed, the cylinder makes an awful noise. It’s nice to be able to tilt it to the ideal angle when desired and when at the sandbar.

[@FilipinoBMW]

Have you tried any of the 4 blades props.

Not on smaller motors, no

[@mriphone1000]

Anyone who wants a general idea on what prop to use for thier application. Can use this equation. It's basically the rpm ÷ gear ratio x pitch, and ÷ then divide by 1056. So if I know a 9 pitch is 6000 rpm on my engine and I want more speed, I reduce my rpm 200 rpm because for every pitch up you reduce it that amount to 5800 ÷ 2.08 x 10 pitch for speed ÷ 1056 = I get 26.40 mph. My engine gets full power at 5500 rpm so know I don't want anything higher than a 10 pitch or it probably will bog under heavy load and probably won't plane.

Brain tickler; I have a 2002 Alumacraft Trophy 185, while it is not a tiny boat, I’m still trying to figure out what kicker I want to run. With me living in PA, 90% of the bodies of water I fish are 20hp max restricted. While my boat has a Yamaha F115 on it, I need a kicker to fish these lakes. I toss the idea around a 15hp or 20hp Mercury EFI, but in reality, what speed am I looking to get out of it? I know I probably won’t plane my boat with a 20hp, but compared to my old man’s 2020 Trophy 185 with a Yamaha 9.9HT, he’s getting 6mph tops… I’d like to get more than 6-7 mph. Maybe around 10-12mph with a 20hp? I’m using this motor strictly for point A to point B travel, I’m not looking to troll with this motor, so I don’t have to get sub 1mph idle for trolling.

[@peterolesens]

Thank you for another cool vid. I think the stuttering with the 9" pitch is because of the rev limiter(?)

[@btv1676]

Agree. Running a smaller pitch will increase rpm at less throttle. So you may be hitting the Rev limit. for break in they may say 'half throttle' but what they want is not exceeding some rpm under load, at half throttle with the stock prop. You're adding a variable and then half throttle is not the same. I'd be careful with the rpm during break in.

[@brandonmclean58]

only half throttle for 20 hours?? Is that right? That must be hard to have to wait so long. I just bought a 2022 20 hp merc and it says half speed for one hour only and then 3/4 speed between 1 and 2 hours with occasionally giving it full speed for 1 minute at a time. Why would there be so much difference?

[@stevenkunka8961]

Tolerances might be tighter on the Yamaha and takes longer to ‘break in’. Mercs have slightly wider tolerances and allow the rings to get seated faster

[@boydlittou9446]

I'd stick with the 25 johnson.

Good morning I would like to know how much a 40hp and 25hp 4tienpos long leg yamaha costs me

[@ep4082]

What do you think about a mercury 25hp four stroke Big foot 03

[@richardcranium5839]

the big foot gives you power trim and tilt with a different gear ratio. i have heard but cant confirm a non bigfoot lower will bolt right on. so if thats the case and you want the power trim and the price is right............

[@ep4082]

@@richardcranium5839 The one I got doesn’t offer tilt and trim not even electric start

[@paullam007]

Just wanted to clarify what you said about the propeller pitch. A small pitch helps with holeshot and acceleration while sacrificing top speed and vice versa as you go up in pitch. Did you say that for your application, the opposite is the case?

[@GYPSY400]

Yes a small pitch helps with holeshot, and a large pitch helps top speed. But In some cases, to high a pitch keeps a motor from reaching its power band... if you can't rev up to the recommended rpm, the motor won't put out the advertised horsepower.

Why not compare the Mercury. 20 with a Yamaha F20?

[@TinyBoatNation]

The merc would beat it
