I'll switch boat brands but my motors are still Mercury!!

"Making Oil", when you check your oil level and it is higher than the last time you checked. Usually from bad rings, leaky injector, etc., basically fuel getting into the crankcase on a 4-stroke.

I owned a 2-stroke 50 HP Mercury and never had an issue in 18 years. Bought a new Lund last year with a 90 HP 4-Stoke, so far so good, love how quiet the 4-stroke is.

I see there is a comment about "making oil"  I am not familiar with that term.  Could someone fill me in.  

I had an evinrude etech for 20 years ran like a champ.  Bought a new boat and it came with a Mercury 115 pro xs four stroke.  Love it so far.

Thanks Capt. Eye Catcher

 Only knock on Suzuki is service availability in your area but now Evinrude dealers are scooping up Suzuki so you may be good.  Yamaha everything are great.  Honda are great motors.  EVERY dealer in WI push Merc.  It's how it is here.  I've had my Merc's...there is a reason I have a Yamaha now and Yamaha everything else. 

You always have a choice when you are buying a motor from somewhere.  Some places just sell packages,  some will sell just the boat.  I bought a new boat a few years back,  Merc dealer.  I said no way,  bought just the boat and put a Yamaha on at a different dealer.

I got a 2003 or 2004, 115 Merc Optimax.  24 trips to Canada, 5 trips to Devils Lake ND, 3 other trips to NDand I have a place on Gogebic.  No issues.  Bought it new.  Save 1500-2000 ish back then vs a Yamaha 115 4 stroke.  If it dies I will buy a Yamaha.

I currently have 4 Yamaha four-strokes...... Three F225's and a T-8. 

The only one that ever made oil was the T-8 on the Walleye boat when the thermostat failed open. 

The twin F225's on the Salmon boats have 1450 hours and still troll awesome everytime out.

I am switching from 15 year old Yamaha 4 strokes on the boat I just sold to two Suzuki 4 strokes on the Alumacraft I have on order. Overall, the Yamaha's were good, but I have been increasingly annoyed by the "making oil" condition. Was wondering how many other 4 stroke owners have been dealing with this, as I don't think I am alone?

I also had a shift rod break on the 115 that required a weld repair, and now the 8 HP kicker seems to be making oil that was not doing this the first 13 years I had it.

I don't think there is much difference in reliability between Yamaha and Suzuki, but thought I would try something different. Not sure if my Yamaha's were properly broken in as I bought the boat about a year old.

The new Suzuki 175 does take a lot of oil though. I think about 2 gallons compared to 5 quarts for the Yamaha 115. New Suzuki's have a 6 year warranty and I believe Yamaha is 5. And I think Suzuki's are a little less $$.

There's no such thing as a bad 150 today. Merc, Yamaha, Suzuki, Honda are all just about bulletproof. Make your decision based on the dealer, and who's going to give you the best service if you have a problem or hit a rock.

Yamahas have been my favorite for awhile now too. Awesome motor.

Had lots of outboards over the years.

The two most reliable for me have been Yamaha, and Etec.  

Etecs are done, so if I had to repower, it would be a Yami.

I have a Yami on my small fishing boat and pontoon, and an Etec on my fish and ski. The Yami’s have performed well. Honda makes a great outboard, but tend to run a heavier than a Yami in some classes.

Suzuki’s are nice too, but there are not too many dealers around if you have trouble.
