Mercury outboard

Recommended Posts

Hey everyone, I am trying to see some opinions about a 2014 Mercury 25 hp 4 stroke outboard motor...the owner says it has around 400 hours of operation.  But runs good...to me it sounds like high hours...what you guys think?

Thanks!

400 hours is not high for 4 stokes.

We used 30 hp 4 stoke Mercs up at the lodge I worked at and they probably had 2000 hours or more when they were replaced.

I believe once you get over 1200 hours they are starting to get up there.

Thanks Dave, now the question is ...should I replaced my 2003 Yamaha 15 hp, 4 stroke with this 25 hp Merc? My boat is rated for 30 hp max. I might looking to get some more speed when loaded.  Yamaha is just perfect, can't complain...just looking for some more speed.

Thanks!

That would be a major downgrade imo. 

 

Mercs don't hold a candle to yammies.

You should gain some top end as well as better performance when loaded.

As far as Sinkers claim of Yammies being that much better than Mercs I don't believe it. 

Sorry Sinker

We had Mercs and Yammies and they were equal in performance and reliability.

I would not recommend Honda's though as we tried a batch out at one of the lodges and the lower units were much less robust than the Yammies and Mercs. The lower units would blow apart itf you hit rocks while the others would hold up well under most impacts.

I was told Yamaha make the bottom ends for Merc.

You will get noticeable performance with 10 extra HP Gino. A 25 HP is 64% more than the 15. Think of it that way. Check my arithmetic I just woke up. Put in a shift at the Niagara Casino last night. I should have stayed home. 

I'll look for a pic without my shades and hat on Gino pisano mio.

Doesn't Tohatsu / Nissan make just about everything under 30 horse for everybody now ?

Tohatsu makes/made small Evinrudes, Mercury, Nissan (I'm not sure they're still available), as well as their own brand.  I believe that Honda, Yamaha, & Suzuki make their own.

No need to apologize. I just haven't had good experiences with Mercs. All Brands are good, and they all have lemons. I had no trouble with my 1993 40hp yamaha built Mariner, and just repowered with a 2019 40hp Yamaha. The old one is still running like a top, and hanging in my garage. I just can't bring myself to sell it lol 

I really like the suzukis too.

It seems like it's shrouded in secrecy who tohatsu makes engines for, you can do all the googling you want and never figure it out, you've gotta have the engines side by side and pull the cowls off and take a look to figure it out

any brand can be great or be a lemon, but I've had good luck with Yamaha over the last 40 years, I just had a brand new merc cause us grief at a remote outpost last week, that seems pretty typical from what I've experienced with merc over the years

10+ addition in horsepower is a big increase in smaller motors, you would be 5hp from doubling your hp. Prices and resale value for what you have and want to get?  On a bigger motor I wouldn't go crazy spending for 10 more hp.

I have found that sometimes an increase in HP when both engines are built on the same block is marginal in reality compared to the same increase if there is a corresponding increase in displacement.

that's interesting and makes sense

the same block could have a bigger pistons and bigger displacement

kinda interesting too, the new Suzukis the 9.9, 15 and 20 are all the same block, same bore and stroke, 327cc, and they all weigh the same

My 15 HP Mariner kicker weights the exact same as my buddies Merc 9.9 does, 100 lbs. Size matters but there are 500HP V 4's out there, or even higher. In cars, maybe boats too. 

400 hrs. for a Merc is just breaking in. If I was to upgrade HP I would go max for the boat. There will be a line up of boaters looking for your 15 HP Yammy. Sell it and get yourself a 30HP fill in the blank _______.

Often if you look a little closer at the specs you will see the higher horsepower comes at a higher rpm when they are the same displacement, they tune them to run a bit faster for the increase in HP.  which does very little for acceleration and time to get up on plane.
