Mercury 90hp. Or Yamaha 90hp. 2-Stroke ? Pros / Cons

**Cougarman46** · 04-02-2017, 02:49 PM

Looking to upgrade to a 90hp.

Looking at:

1987-1997
Mercury 90hp.
Weight 265 Lbs.?

1984-1995
Yamaha 90hp.
Weight 223 Lbs.?

Both are Re-man's, currently rigged with Yamaha
Which has been great and I have nothing against
It or know much about. (Came with boat)

Just always been a Mercury fan.
So if I were to upgrade in power now
Would also be the time to re-brand.

So for the big picture, I would like to know

The pros and cons of both.
Parts availability of both long term.
Etc.etc. etc.

Look forward to your thoughts

Y... I've seen the same motor since it was new and it's still showing off.

Hard to beat a 3cyl Yamaha.

If you are going to run it standard then the Merc, but must be the later style with the drop on cowl.
Lots of low down grunt, great economy, hold its head against the Yamaha in just about all conditions
If you are going to run it hard or fast or want to do modifications then go for the Yamaha

Any particular year you like for the ( Yamaha 90 hp. 2 Stroke )?
Any mods you like for a nice warm up, not a maintenance nightmare?

One item I would like to do right away is have the midsection
modified to a 15"

I am a Yamaha man 100%,

But, If the hull is heavy and or will be loaded most times, one thing to consider is the Merc has quite a few more cubes and a lower gear.

If that's not the case, medium to light hull, not carrying a huge load. The Yammi is flawless. If you have any intention of tinkering, only Yamaha. To shorten the mid is no biggie.

My hull is 940 Lbs. As is, Rigged with fuel.
with the current 70 hp. It does 40 mph with
my wife and I.

Thoughts were, 90hp. 15" mid.
Low water pickup if possible and
Set a better (x) dimension.

Possibly warm it up, but still a daily
Little hot rod, not a maintenance nightmare.
