Yeah, I know, not green. But the 2.3 Honda was shaking us to bits.

I'm hoping this will be quieter and less of a bone shaker.

4Hp Mercury for what I considered a snip. Good 2006 model it appears. One thing, what the devil is Mercury on, they say for storing (in my case in a small next to engine cavity) it has to go on it's end!! Can I not put it on it's side?

Any views?

Regards,
T
 
sure, one of the benefits of 2 stroke. let the engine run after disconnecting from petrol tank to run fuel out of carb. Then can lay on side opposite gear shift.

Yep,run it dry but with a Merc 4Hp, you can lay it either side... If it's a 2 stroke. /forums/images/graemlins/cool.gif

But I think you'll find it's a 4 stroke! /forums/images/graemlins/shocked.gif

If it is a 4 stroker they don't like to be stored other than upright as the engine oil runs to all the wrong places. If it was a 2 stroke, I would expect it to be older and also a 5Hp not a 4Hp both single cylinder. :confused

Let us know when you've checked.
 
HI there,
Ive got a 4hp merc long shaft 2 stroke.

Not been used for 3 years, i cant remember the fuel ratio.

HELP. someone must know. 50:1 rings a bell but could be 100:1 HELP HELP

thanks guys.

kind regards,
Les.
 
Almost certainly 50:1

Id use 50:1 even if it is supposed to be 100:1

The owners manual will tell you

If you have mislaid your copy you can down load one from the "Download Center" at http://www.brunswickmarineemea.com/

If you have forgotten the year of manufacture then there's a year identifier there too

PS Got a question, better to start a new thread rather than hijack someone elses. Some forums would just ignore you /forums/images/graemlins/shocked.gif

PPS I checked the manual it is 50:1.

But that's for long term storage to ensure all water is drained from the cooling system.

Normal carrying position is on its back using the carrying handle.

Once drained you can lay a 2 stroke down any way, unlike a 4 stroke, but it is better to ensure that the prop end is always lower than the engine end just so no residual water can get into the engine.

The 4 strokes must be stored either upright or lying on their tiller side due, as you are aware, to the oil filled crankcase.
 
It's definately a 2 stroke. Very pleased with it although it's bigger than I expected! My little 2.3 Honda is a gnats tadger alongside it.

Ah, thanks the on it's nose orientation is for long term storage. I was worried about that! So will I be able to get my flat bottom tender up on the plane with this? /forums/images/graemlins/laugh.gif It's a short shaft. We live in an old mill house so will try it on the river boat tomorrow! Can't wait to go to the pub in it, the 2.3 shook us to bits.

Les, it's 50:1 unless you running in then it's 25:1 for a few hours I think.

I can get my slatted floor Quicksilver 240 to plane with the 5hp version of the same engine and I weigh 16.5 st /forums/images/graemlins/blush.gif

I had so much fun jumping waves, I broke most of the slats /forums/images/graemlins/shocked.gif. Anyway, bought new slats: well worth the money for the grin factor.
 
Running it on 50:1 if it is 100:1 won't do any harm; the opposite probably will.

I remember a few years ago when small outboards were coming out at 100:1, the engineer who worked on mine said to run them on 50:1 anyway. He reckoned it would make them last longer.
 
I'm really picky about what goes into the "big" engine.

As for the little engine, if it's "in the garage, looks roughly the right colour, and doesn't have too many spiders in", it will do...
 
You should use Outboard engine 2 stroke oil to the current TCW-3 specification. RTFM!

Oil for other two strokes is formulated for air cooled, not water cooled, engines which runner hotter. The viscosity is different for a start! TCW3 is also biodegradable.

You may find you have a choice between mineral and synthetic or semi-synthetic varieties.

Having said that almost any oil is better than no oil!
 
Bear in mind that I been in the motor trade for 25 years, been a competition motorcyclist for 30 years and a motorcycle techie for 10 years before you poo poo this post.

It is imperative that if you double the amount of lubricating oil in your petrol that you check the plug colour very carefully at all rpm ranges.

You may find it is running lean and could overheat.

You may have to increase the size of the main jet to compensate for the lean condition.
 
Hi there VicS,
Thankyou. you are a star.

I know ive got a manual somewhere?????? *%*%

Thats a great help.

kind regards,
Les.
 
On my classic speedboat I run a 2-stroke Merc 80hp Blue band. You won't get me putting anything but Quicksilver 2-Stroke Outboard Oil TC-W3 in the fuel for that. Do be aware, mixed fuel goes off after around 3 months.

Also I do measure it out Very accurately which I strongly recommend, not something that should be guess...IMO! /forums/images/graemlins/ooo.gif

[/ QUOTE ] I use a laboratory conical measure. A bit OTT perhaps but it will measure small volumes with reasonable accuracy when mixing a litre for the mower or the Seagull but will also measure 100cm³ when mixing 5 litres of 50:1.
One lives in the garden shed another, larger one, on the boat.

Must confess to storing 2 stroke mix from one year to the next. Only in full metal cans though, always filtered and mixed 50/50 with fresh before use.

Oh really ?

Fuel 'goes off' if vapours and light ends are allowed to vent of. Second that light has an effect on anti-oxidants and Octane enhancers used in gasoline. Third storage in warm conditions will exaggerate both above conditions. So store in air-tight containers, in cool dark place and it will last years.
If 2T is already mixed in it - degradation of the mix will not occur for some time - but mixing (good shake !) is advised before putting to a tank to ensure that you have 2T in all the gasoline. Storing mixed 2T and gasoline is feasible from one season to another and I for one do this regularly. In fact I proved to all at last PBO Meet I did that my Mariner 2 started quite happily and ran without trouble on 3 yr old gasoline mix that had been left in a can in my transom locker.

Accurate mixing - as long as you do not go LESS than required there should be no problem. And if you are running a 100-1 on 50-1 which is a good idea BTW ... then don't overdo the oil mix. Keep to 50-1. Me ? I use the scale on side of the 2T bottle. Why have more smelly, oily, petrolly items around when the bottle gives adequate scale to use.

OK - if you are racing, running Blue Band engines etc. - I accept you are going to be fussy and keep strict regime - understandable. But the average bod with his outboard and tender ??
 
Maybe performance motorbikes, but we are talking small marine outboards - old design and old technology. Also water cooled and probably seldom get up to full operating temperature. I wouldn't worry too much and wouldn't bother with regular plug checking.
