Hunter 701 fitting an inboard.

[langstonelayabout]

You make these sweeping statements but to put the matter in perspective:

My 2 stroke 6hp Evinrude "Yachtwin" weighs 27.4 kg

If I was thinking of replacing it the modern 4 stroke with the same basic features, ie long shaft, high thrust prop and battery charging, that would be an obvious choice is the Tohatsu 6hp "SailPro"

The 4 stroke 6 hp Tohatsu "SailPro" weighs 26.1 kg

The arithmetic I use makes that lighter not heavier at all and IMHO it would make an excellent lightweight propulsion unit for a Hunter 701 for not much more than £1000

My last two outboards were 4hp sailpower types (big, slow prop, charging, etc).

The 4 stroke Mercury was about 26kg. The 2 stroke Mercury about 18kg. (both single cylinder)

Whilst there is 8kg difference between them, that is 8kg less in the third worst part of the boat (aside from the bow and masthead).
I'll be pleased to go with the principle of I'd prefer the lighter outboard to the heavier one. If I needed a new one, I'd go sailing to Guernsey and pick up a nice new one at a reasonable duty free price.

And don't get emotional with me for liking what I like! lol

 

[langstonelayabout]

All this is irrelevant bullshit!

You were trying to make out that 4 stroke outboards are so heavy that its impossible to lift them off the floor.

My point is that this is not necessarily so.

They're not difficult to lift them off the floor. The difficult bit is lifting the flippin' things over the stern. They all weigh at least 150kg as you try to position the clamps over the outboard bracket...

 

[langstonelayabout]

Some fair points in there, but doing much motoring with a 1GM installed as an afterthought in a small boat is still unlikely to be an experience I'd invest £4k or whatever in. Better to spend the money in the cafe waiting for a breeze IMHO. Or sell the kids and trade up to a boat with a 3cylinder motor.
Just my opinion of course!

Yes, have just changed from a 25' boat with a 1GM10 to a 27' boat with a Beta 20.

I can confirm there is a huge difference! I still wouldn't want to sleep next to either when they are running though...

How Sad you are to have to revert to swearing.

I'm guessing you never sailed dinghies and learned the value of trim - a big engine hung off the back of a Seawych would make any proper sailors' toes curl.

Hey guys! Cut the animosity.

I motor sailed a 27ft with a 1GM for 5hrs a few days ago. While I would rather have turned it off, it was not too intrusive. No sound proofing. If I was trying to kip next to it. I would need to be pretty tired to sleep. But no worse than an OB in a well. (when I was younger, that was what we used and I managed to sleep in the quarter berth)

I also sorted a 6hp 4T long shaft engine for a friend. It was quite heavy, way more than our 5hp two cyl 2T from 40yrs ago. But there are good reasons for that and I would prefer the new one to the nice, but tricky old one.

YMMV

.

Guess as much as you like but you are wrong,

I fail to see where the sailing performance of a Sea Wych ( two words by the way) or its keel configuration has any relevance to an argument about the relative weights of two stroke or four stroke outboards.

You claim that four stroke are so heavy that they seem to be bolted to the ground I quoted figures to show that they are not necessarily heavier than the two strokes they might replace

Thise weights are still the same whatever type of keel my boat, your boat or anybody elses boat has,

The weights are also still the same regardless or of my dinghy sailing experience.

What are you preparing for in your next life ? Politician ?

 

[fredrussell]

Also to be factored in the comparison of 2-stroke and 4-stroke outboards is the fact that a 2-stroke is a good deal thirstier than a 4-stroke so if you are planning a longer cruise you may well end up having to carry an extra 5 or 10kg of fuel.

I hadn't realised how much difference there was in efficiency between 2T and 4T motors until recently. After running my new 4 stroke 2.3hp in the tank at home I switched the fuel off to drain the carb whilst running. It took so long to run dry compared to my 2T motor (same HP) that I was convinced the fuel stop lever was buggered. I then assumed that the float bowl on my 4T carb must be much bigger - nope, on inspection they're very similar in size.

Well I think the OP should stick with an outboard. The only reason for modifying to an inboard is an obsession with inboards and motoring. In which case he should sell it and buy a boat with an inboard.
regarding the outboard hung on the transom I have the 6HP Johnson Vic refers to. It hangs on the transom of a light weight 6.5 m lift keel TS. The bracket is adjustable in height so that even in a big swell it can be lowed to give drive at all times without cavitating. I lift it up one stage for smooth water operation for less drag. The weight can be largely offset by moving gear forward inside. Or best get crew up on the side or front.
Having said all that it much depends on the type of sailing and conditions you sail in. I used the motor so little that I stowed it up in the forward cabin. Then finally decided to leave it home. So I just sail and paddle. That is is because conditions here are much more benign and predictable. (Regular wind and little tide).
So at least OP should give the o/b a try. olewill

Classic diversion tactics.

You claimed that 4 strokes are heavier than 2 strokes. VicS came armed with facts rather than the pub nonsense you seem to favour, and instead your try and change the conversation to his boat, which as you no perfectly well has zero relevance to the weight difference of a 2T and 4T outboard.

Be man enough to admit that you're wrong.

Try actually SAILING THESE BOATS AND USING THESE ENGINES !

Then you will understand my comment ' What joker bolted this to the floor ?! '

Saying otherwise just displays ignorance of real life or sailing experience and actually trying it rather than relying on brochure figures.

VicS our boats are not too far apart, you're welcome to a try lifting my engine - and the sailing performance - compared to yours....PM me for a meet please - Andy.

You're delusional.
So your saying that despite the 4T engine weighing less, on the scale, when you pick it up 'IN REAL LIFE' it weights more?

My father used to own a 701 so I know how they sail, but its somewhat irrelevant. We're talking about engine weight, and the boat can't tell the difference between a 27kg engine that's 2T and a 27 kg engine that's 4T. To suggest otherwise is to suggest that somehow the laws of physics don't apply to your own boat.

FWIW I have owned boats with 2T and 4T outboards, and weight was the same for both of them. The 4T was better in practically every way, noise, economy, starting, apart from storage where the 2T could be chucked in any old way.

Thanks very much, I've been called a lot of things - most of them unreapeatable on here - but ' Delusional ' is a first which I shall treasure.

I'd like to see your experiment with 2-stroke and 4-stroke engines of the same horsepower weighing the same.

Why are you continuing with this nonsense - particularly has he has just explained that he has done exactly what you are suggesting.

i thought you claimed to have some engineering knowledge which might lead you to appreciate that both he and Vic have proved that there is minimal difference in weight between the two engines in question.

Does not mean that they are easy to handle, just that they are BOTH equally difficult.

You are suggesting that the brochure figures for my Evinrude and the website figure for the Tohatsu are wrong?

I doubt it !

Try lugging about the engines mentinioned here then report back, heros !

I've been "lugging" , as you put it, the Evinrude about for the past 32 years..

Every year I lift it off the boat , stick it in the back of the car and bring it home for its routine service.

Then it spends the winter in the corner of the workshop

At the start of each new season it gets another quick run in the test tank before going back to the boat.

Here it is on the back of the boat

Here it is getting its annual pampering

and here is in the corner of the workshop

Well don't blame me for the heavy engine hung off the end ( worst place ) of a boat which already has inbuilt design drag then

And please don't use my website- that was a particularly shitty thing to do and speaks volumes about you.

 

[TSB240]

I have a practical solution to the Op's quandary. I suggest that whilst you are waiting for that bargain lightweight second hand diesel engine to become available you invest in a lightweight 2 cylinder 2 stroke engine a Johnson or Evinrude 4 HP. I believe it still can't be bettered for its power to weight ratio. 2 cylinders give a smoother performance than the big single cylinder thumpers. (2T or 4T). It is easier to start with a virtual guarantee that if one cylinder fires the other comes to life. It is easy to handle on and off and stow away and can also be used as an outboard on your inflatable or tender.

I speak from experience as a recent owner of largish 24 foot dinghy with a lid!

Try it on the stern but I reckon you will soon get fed up with the difficulty of operation and removal at sea.

Have you thought of cutting a hole for a well? :encouragement:

We used to have a 20 foot day boat of which a number threw away their impractical side mounted outboard brackets. They cut holes and built up wells internally. This generally gave much easier use and guaranteed drive in wind against tide conditions that would challenge any transom mounted auxiliary. Faired off by a plug engine removed guaranteed as good sailing perfomance as original designer envisaged.

Oh but by the time you have done that you will have a mini A22 but probably quicker!:disgust:

Nobody was blaming you for anything. I am reasonably certain you had no hand in fitting it .


And i have not knowingly used your website. I have no intention of using your web site. Why would I want to? I expect that it is full of the same garbage that you post on here but I suggest if you don't want people to use it take it down .

I dont think Id know how to find your website ...... Google would though i suppose
