Before You Buy: 2023 Mercury 15 HP Outboard Motor

[@The_Mechanic_Dad]

Just got a 2021 15hp for my Jon, and after 8 hours of being on the water, I'm nothing but pleased with it. Quiet, super fuel efficient, and good power delivery.

[@mattwaters6987]

Great video bro! Luv my 9.9hp 2018 Merc. Was contemplating the 15hp but hey, I'm good. Happy fishing! 👍😊

[@keenexplorerTV]

Great motor, I have the 15 HP 2015 model

[@stevencamara2778]

I got the 2021 20hp four stroke with the electric start it’s on my 14 1/2 Grumman aluminum awesome motor fast quiet sips fuel very very happy with it I have not heard any rattling but coming from a 1986 two stroke 20 hp it’s a big difference in sound levels

[@msanchez415]

Me too! Just got my Twinkee! She's awesome . On a 12 foot zodiac going around Alcatraz and mcovey cove S.F C.a

[@BackOutside]

excellent video man, wow

[@InlineOutdoors]

Thanks man! I appreciate that!

[@jamesthomas7928]

The bulb does get hard - maybe the gas tank air tap is closed. I've got one on a 12ft RIB and it is fierce if you don't take it easy on the throttle

[@kajmolin297]

Good motor. I a 15 hp 4stroke 2008.

[@jeremiahblack3775]

Nice video 👍

[@InlineOutdoors]

Thank you! I hope to use this motor a lot more during hunting season this year!

[@makinawake9178]

Thanks for the info on the 15 considering it if I can find one around (weird time to shop for some things these days)

[@InlineOutdoors]

I got this one from Cabelas and they had a couple on hand at the time, it may be worth checking out!

[@makinawake9178]

@@InlineOutdoors had to google the store name, and we actually do have one in this province (Canada BC) but the website isn't showing me anything... Outboards pretty thinly spread around from what I see lately appreciate it I'll keep my eyes open

Hi, what is the maximum transom thickness for this outboard? My transom is 63mm.

[@kajmolin297]

I have electric start, and it run good.

[@markcollins5026]

Man, I just got a new 2022 Mercury 15 hp EFI, it takes 4 or more pull's to start hot or cold, the fuel hose that comes with it has a kink in it, will not come out so I just ordered a good quality fuel hose assembly with bulb, I'll see if that helps !

[@InlineOutdoors]

I would tell the place you got it from and maybe they can look at it for you. If it takes more than 2 pulls, 3 at the most there could be something wrong with it. Sometimes mine starts a little hard when it’s extremely cold. Good Luck!

[@markcollins5026]

@@InlineOutdoors man, it runs fine once started, the fuel hose was folded in half and the kink won't come out, so that and that big emissions valve they have in the fuel line is not helping, I haven't had the motor at the lake yet so not broke in, I'll see if the new good quality hose assembly with no big valve on it helps, maybe I'm just weak !

[@johnbultemq8026]

I just bought the same 15 Hp motor for my 14 foot jon boat. My question is when installing it should I mount it on with 2 lower bolts? Should I drill 2 holes and bolt it on the transom ?

[@InlineOutdoors]

Yeah I mounted it with bolts so it can’t fall off

[@johnbultemq8026]

@@InlineOutdoors so you have 2 bolts on top (twist) and 2 drilled bolts on the bottom. ? Total of 4 bolts?

[@InlineOutdoors]

@@johnbultemq8026 yes 2 twist and 2 drilled so 4 total!

[@jimking2299]

I just ordered that exact motor yesterday, for the same reason: just didn't feel comfortable with the clunky old motor we had been using. $800 repair bill on a 25-year-old engine seemed like a poor investment.

[@InlineOutdoors]

You will love it! I hated the uncertainty of whether or not my old engine was going to get me to where I needed to go! The new motor is a huge confidence boost for this!

[@Kana0211]

I have 100% trust with my 97 merc to go wherever I want to. Just went 12 miles full throttle for 95% of the journey with no issues. Although it's my first time doing that.

[@inflatableboatadventures5030]

I bought one Before I watched this

[@98red300]

Does your motor have a rattle sound when running? Tiny boat nation has mentioned that the 15 and 20 hp Mercs have a weird rattle sound. He said that it's completely normal and most of them do it. I'm looking to buy a 20hp merc in the next couple of weeks. I was just wondering if your motor made that sound? Thanks

[@InlineOutdoors]

I don’t recall ever hearing a rattle sound and I’ve ran this motor a few times now, I could be wrong but I think I would have been alarmed if I heard a rattle out of a brand new motor. Do you know what causes it?

[@98red300]

@@InlineOutdoors Thanks. I'm not certain what the cause is. Another you tuber called Tiny Boat nation just mentioned it. Someone also mentioned they heard the same noise in the comments.

[@98red300]

@@InlineOutdoors kzbin.info/www/bejne/omibo4icjdmJaaM here is the video where he mentions it and if you scroll down just a little you will see the comment the person leaves about hearing it too.

[@InlineOutdoors]

@@98red300 I probably wouldn’t worry about it? These motors run awesome. They are quiet and have lots of power. I am very pleased with my purchase! If buying brand new, I’m certain there is some kind of limited warranty as well.

My 2019 does but only while taking off

[@davorfsunjich5209]

is your caVITATION PLATE ON SAME LEVEL AS BUTTON OF BOAT. TO ME IT LOOKS TOO DEEP

Hey buddy I have an idea older 18’ flat bottom boat that a guy baught brand new back in the 70s and used it a couple times and then put it in a shed and never used it again!! I got it from a buddy of mine witch he had put a big 110hp motor on it but never got time to try it out!! When I got it I took the 110hp off and got a Johnson 35hp and used it for a couple years but have been having issues with it ever since!!! It starts but when putting it in forward mode and gassing it up it wants to die and I have not been able to figure it out!! I’ve been thinking of getting a new motor one that is much more reliable!!! I was also able to build a steering council so I don’t have to use a tiller handle!!! The Johnson 35hp came with a tiller handle but I could take the tiller handle off and set it up for a steering council set up so that was what I did!! I would like to no your thoughts on what size motor would be best for my 18’ wide body flat bottom boat?? It is an older boat so it is built pretty tough and not like today’s flimsy metal is!! But it is pretty light in weight!! I also have a 24v trolling motor on it that is like 65lbs or 85lbs thrust and it works great all day long trolling around the lake and using the spot lock on it!!! Well thanks in advance for any help buddy!! Oh I also live in southern Iowa Osceola Iowa!! Thought you might no were that is at?? Well buddy remember keep up all the hard work buddy!!!!

[@InlineOutdoors]

I would highly recommend getting a new motor! While yes they are a bit of an investment, they are so much more reliable than the old stuff out there. As far as size goes for your 18 foot boat, I would say that a 20-25 HP motor (should) be enough to get your boat on plane. With that being said, if your want to go fast I would say maybe go up to a 30 or 35. Does the 35 Johnson feel like enough power when it does work? It sounds to me like you’re not getting enough gas through your gas line. Have you tried new gas line and ball? Sometimes when that stuff gets old those ball pumps tend to crack and not work. Just a thought, but maybe you’ve tried that already! Also, I know exactly where Osceola is, I work in the Des Moines area and sometime go down that direction for work!

[@j.j.clingman4083]

@@InlineOutdoors awesome buddy!! There is a lake there by Osceola that has a couple duck blinds on it!! I never see anyone ever using them though!! If you ever want to check it out let me no and I can show you and see if you might want to hunt it sometime???

[@InlineOutdoors]

@@j.j.clingman4083 That sounds cool! We will have to go hunting together next season for sure!

[@rstgyro]

I’ve got the same motor and I’m very unhappy with mine. Sometimes it takes 20 pulls to start.

[@InlineOutdoors]

That doesn’t sound right. It should start in 2 pulls every time. Something must not be working properly

[@garycotz563]

How much does the 15hp weigh?

[@InlineOutdoors]

Hi Gary! If I remember correctly, it is just shy of 100 pounds. Just based on lifting it, it is manageable by yourself but is much easier with two people. I bolted mine to the boat so it’s not going anywhere now!

[@teeanahera8949]

You don’t add oil because it is EFI, you don’t add oil because it is a four stroke.

[@Kana0211]

77 pounds for my 2 smoke heehee

[@kerryprance3767]

Tohatsu's are a bitch to work on. I could do 4 yamaha impellers to 1 Tohatsu.

You guys do realise that all Mercury outboards 20hp and under are rebranded Tohatsu outboards. Blind leading the blind
