I need to know the pro's and/or con's of the Mercury 6hp 4-stroke outboard.
And let's be honest :smile: :smile:

Well lessee ....... It weighs more, has less torque, costs a whole lot more and is less convenient than its 2-stroke brother. Lots of advantages!

10-30-2002, 07:43 PM

It gets beter fuel economy and doesn't dump oil into the water. Why would anyone get a 2 stroke. Less convenient? Thumper are you pushing my leg here? You don''t have to deal with 2 cycle oil. I will never buy another two stroke outboard!

four stroke, cleaner all around! merc 6hp, single cylinder that is the only draw back I see. :shocked: weight shouldn't be a big factor with a 6hp.

If you're talking about a kicker motor, 4 stroke is the only way to go.
Normally, I tell people if you want neck-snapping, white-knuckle power, get a 2 stroke.
If you want clean, quiet and economical, get a 4 stroke.
But 6 HP? You ain't gonna get any power out of a 6 HP anything. A 4 stroke is heavier, a tad slower, a little more maintenance and might not last as long as a 2 stroke. And a few more $$ if you gotta rebuild it if you have it a long time. But that's all offset by no more premix, no more smoke, no more fouled plugs and it'll troll for a week on a 6 gal. tank.
I've never owned a Merc 4 stroke, but if it's half as good as their 2 strokes you'll be happy.
Black in back, baby!

A Mercury 6 HP 4 stroke weighs 55 pounds. The only problem is that it has only a single cylinder, which means vibration. The 9.9 4 stroke weighs 110 lbs, but has 2 cylinders.

Keta,if the thing is going on a boat that has 2 motors,then the big engine is the deciding factor.If we assume that they both run off of the same fuel tank,then why have a 4 stroke and a 2 stroke?Now we have to get seperate fuel tanks.Remember which is which(this is either simple or hard,depends on how big the fuel tank for the big engine is).Of course you already know this so I will stop now.
Anybody wanna race a 240 sport jet against any big block with any pump you choose?I have ridden in a 20'NR with a 502 Chev(I think it was a 502)the engine put out over 500 horse according to it's operator.I beleive him.A 20' sport jet 240 was faster out of the hole,faster to accelerate,and had enouth top speed to make my eves water(50 mph plus).Hmmm I womder why i would want to hang a 2 stroke on the back of my boat.

I have that motor on my boat. I have a 17' aluminum, the 6 hp is the kicker motor and it is great. Dependable, quiet, and as said earlier, no smoke, and it has plenty of power to push the boat when trolling or just holding in current. I wouldn't want to try to motor against the current in the Columbia, but it would at least get me back to shore in an emergency. My big motor is not a four stroke but this is not a problem because it is oil injected, so both motors run off of the same tank. No complaints from me. Hope that helps.

flatfish, do you mean you run your 2 stroke kicker off of your sportjet tank? i have a 175 sportjet that i run my 4 stroke off of the main gas only tank. i did not know one could run a 2 stroke kicker off of the mixed gas of a sporjet.

Flatfish · 10-31-2002, 08:50 AM

FIL
I do not have a sport jet on the back of my boat.I have a drifter.Good idea though

! What I was trying to say is 2 things:
1-If your main tank that runs the big motor is premix,then run a 2 stroke kicker.I would hate to try and remember if I put oil in that tank but don't put it in that on there!

Particularly if you are running multiple 6 gallon tanks.Sorry charlie,too easy to mess up.
2-Four stroke performance has not caught up to 2 stroke.That simple.Some folks don't like the idea of an engine that spits oil into the water.Well that is the price of performance.The new 2 strokes are much better about this than the older units.But bottom line is not HP in a jet but how fast the engine gains RPMs.The 2 cycle is in another league in when compared to the 4 cycle engine.
There is nothing wrong with a 4 stroke.Great motors.There is nothing wrong with a 2 stroke.Great motors too.Let the gas tank decide.

Flatfish,
Ok I'll race you, but it will have to be a long distance race with equal amounts of fuel. :grin:
You can't use your drift boat, :shocked: rowing is not fair :shocked: !

My main motor is a 30hp Honda so fuel incompatability is not a problem.

I haven't noticed any differance in top speed, just how fast it gets there. I am not in that big of hurry anyway, I am more concerned with getting there and back with the limited fuel capacity that I have. That and I don't like putting oil into the water.

The extra weight of a 4 stroke is a concern in a drift boat.

Keta,
my rule of thumb for big motors is this
If it has a prop(not kickers here)then 4 stroke(see tuna fishing).If it has a pump, 2 stroke for reasons listed above.Jets are a lot of things but efficient aint one of them.
Row Row Row your boat...

Hay "fishingfirst" do you have any vibration poblem's W/your 6hp. 4-stroke? I will running it with other 4-stroke :smile: :smile: "No Mo Smoke"

fishingfirst · 10-31-2002, 02:26 PM

I don't have any vibration problems with it that I have noticed, my boat is heavy enough to absorb any of that. I have had older two strokes that were much worse.

This is my first experience with a four and am pretty impressed. I would recommend them to anyone. One of my fishing partners has a Honda on his boat, I think it is better but also alot more expensive. His has about the same vibration as mine, it is just quieter.

I'm gonna miss 2-strokes when they're gone. :depressed: First it was dirt bikes, then outboards, now PWC's, next will probably be snowmobiles. When I was shopping for a weedeater a while back, Ryobi even had a 4-stroke weedeater :shocked: Can't wait to see a 4-stroke chain saw.
You can't dispute the performance of 2-strokes. Anybody who's ridden an old Kawasaki H2 triple cylinder death machine will tell you that. So will anybody who's shot across a frozen lake at 130mph on a stock Polaris Storm. Remember the old in-line 6-cyl 90 and 115 Mercs that were on every other boat 15-20 years ago? Best freakin' motors to hit the water........now I'm getting nostalgic.....sniff sniff.......I think I'm gonna cry!
I'll have to eat a half-gallon of Double Chocolate Chunk before I feel better.........

Fishing is life,
I have one of the 175 Sport jets and run my kicker right off the main fuel tank. I am not understanding your question. My SportJet is oil injected which means that the fuel coming out of the main tank is not mixed untill it gets to the engine.

"i did not know one could run a 2 stroke kicker off of the mixed gas of a sporjet".

Do you have an older one that you have to actually mix the fuel and oil in the main tank?

As to running a 2 cycle off of mixed gas unless I am way off base 2 cycles need to be premixed. My kicker is a 2 cycle but also is oil injected with an oil tank on the motor. Problem solved.

lpump : I owned a 500 Kaw . Jist sold it 2 year's ago for more than i payed for in it 73' new. :smile: :smile: so i know what you mean. :smile: :smile:

ReelMcCoy, i was confused by another post. my sportjet is like yours. it mixes the oil into the engine. i run a four stroke kicker off of the main tank. i like the idea using your 2 stroke with oil injected in the engine. the reason i use a 4 stroke is to avoid the extra tank of mixed gas.

Red · 11-01-2002, 09:27 AM

Fishdog,

I have run honda 4 strokes since 1984. I can tell you the advantage of a 4 over 2 stroke, but I don't know about the HP size and vibration. 4 stroke = quiet. You don't have to yell at your fishing partner. 4 stroke = no emissions. You don't go home with a sore throat after 8 hours of trolling. The only disadvantage I have found with my 4 stroke is less ability to troll down slow. I fixed that with a sea anchor hanging out the side. Then got a trolling plate. Finally fixed the speed problem by buying a big heavy boat. :grin: :grin: Oh joy. :smile:
