Murphys Law

This evening I gave my ancient Suzuki D2 outboard a static run in a barrel of water (its back from being borrowed for about 12 months) after cleaning the plug it fired and went well...........this motor will go in my Hudini.
after idling a bit rough it settled down and I ran it for about 10mins all good.I decided to drain 98% of the fuel and let it run dry so I could clean it and generaly give it sime TLC.
started it again and let it run at a fast idle all good contemplated grabbing a beer while it ran dry when it let out a sound like a cat got caught in the prop........shut it down immedietly.
Kinda glad it happened in backyard and not on boat something has gone in drive train as power is not coming to prop feels like its at the top end of drive shaft.
So now its in for a teardown which probaly is a good idea found a manual on Ebay and thats on its way now. at least it will be easy to clean and paint in pieces.
Hopefully its no more complicated than my mower or chainsaw a nice break from sanding.

Cheers Paul

I am curious about two things: was it in gear when it failed? and was a good flow of water obseved coming from the tell tale?

I've had two of these and found them to be very useful little engines ( sorry Thomas the tank engine) . If its the same model as mine the engine is air cooled, the exhaust in the leg is water cooled from a little pump at the lower end of the leg, and there is no gearbox. They are indeed very simple engines and easy to work on as long as you can unstick the screws and bolts. The best unsticker I know is not WD40 which is in my experience no better than kerosene mixed with engine oil, its Inox or CRC Marine.
I'd suggest that you go and get some, and give it a good spray every day until the day you are going to tear it apart.
I'd suggest that you look at the lower end of the leg where the bevel gears are, there are several things can go wrong there and which will produce those symptoms.

Good luck, do keep us posted.

Motor has no gears as such its direct drive

Its an early eighties model I bought with an old GRP dinghy from an old lady who had both from new. She used to leave the dinghy tied up in the bush at the river and carry motor to it.

One day the dinghy went missing and Betty was not impressed Bemm River was not the sort of place where things got stolen.

About 6 months later the dinghy was spotted some distance upstream recognised and returned to its owner.

It would seem it had been borrowed by a druggy(Bettys words) to get across the river to tend his pot plants, When it came into my possesion it still had remains of the black paint that had been sprayed all over it to help it blend into the bush.

A friend and myself gave it a full restore job and called it B.O.B. (Bettys old boat)

Water was coming out of exhaust up leg ,there is an impeller to pump water I didn't know it was air cooled as John suggested........ will know more when manual arrives.

I did not recognize the D2 prefix so I assumed it was a water cooled model with gears. Johns recommendations are good and I agree with his comments re WD 40, we have something called GT 85 over here and it is quite good, or even a bucket of diesel fuel and a long soak. My dad used to find a dry thread was an open invitation to apply some copper bearing grease and I never had to struggle to release anything that he had done up even after years of exposure to salt water. It was a godsend in shipyards where releasing a Kenter shackle in an anchor chain used to involve lighting a fire under the bloody thing! Good luck refirbishing your engine.

Finally found an hour or two to spend on the engine.........bottom end is OK the problem appears to be at top end of drive shaft.
Shaft to prop has a female splined collar that must slot over lower end of crank shaft........ female end appears OK but there is evidence of metal dust and I can't see male end of crank. My J&J parts list seems to indicate that this male part is replaceable so I guess I'll have to remove power head when I have time for a better look.........so far the motor is comming apart easily and is in good nick under the grime........cant think why splines would strip though.

Cheers Paul

......cant think why splines would strip though.Paul

I know nothing at all about the motor you speak of but it seems to me that a well designed motor would have something protecting it in the event of a seizure - anywhere along the drive train. Usually there is a shear bolt or an easily strippable thread, whatever, to afford such protection. And that sacrificial part is invariably replaceable.

Any number of things may have caused the splines to strip but look for the easily replaceable, and affordable, parts and replace 'em. It may be that the male part you've already identified is the one you need but you would be best to find someone who knows the motor and can tell you more.

Hopefully, someone here on BBJW will be able to give you some better guidance than I can.

Good luck with it, mate. Me, I wouldn't even try to do what you're doing. I would hand the motor to a specialist and give him enough cash to fix it. I never mess with engines, even when restoring old cars. It's an area where I just know I will take it all to pieces and put it back together to find some parts still sitting in a box where I put 'em during disassembly. :Christo_pull_hair:

[Mike]

Any news yet, Paul, on what this problem was? Have you resolved it and got out on the water yet?

Curiosity is scatching away at me. :waving:

[George Waite]

Mike
Your comments re a "shear point" somewhere in the drive train are correct until someone gets fed up with replacing it and PUTS A BIGGER ONE IN. Then the next most vulnerable (and probably very expensive component, will fail). If the crank end splines are gone it is usually a new crank unless it is of a material amenable to weld or spray build up.

[Mike]

Yes, George, and that's probably why this thread has its most appropriate title. You can never quite avoid Murphy when it comes to some people, which is why I tend towards buying things like engines new rather than second hand - unless someone like you can vouch for it as a sound donk. :D

[bemm52]

Mike and George I missed your entries yesterday..........I'm afraid not much has happened on the motor front,for a couple of reasons
1 Ive been turned my Houdini upsidedown to kevlar (bastard of a stuff to work with in my opinion) bottom and glass the sides.
2 I kinda don't like working on oily things when I,m trying to do clean things....ie wood and fiberglass.
may get into it on weekend if time permits.

The child out of wedlock word not allowed :embarassed: opps???? HaHa
Ha ha. Enjoyed those two posts, cobber. :rofl:

The b word is banned because here in England people take offence at it. They don't use it like a term of endearment as some do elsewhere, which is something I learned the hard way. Likewise the word 'spunky', which I always thought meant gorgeous and desirable in a woman. I had a pint of beer tipped over my head by a barmaid I described using that word - and made 'persona non grata' by the landlord. I had to ask what that meant, by the way.

I am inclined to delete all the banned words bar just one or two and may just go and do that. I kinda like using the odd swear word myself. Lends emphasis when used properly, don't you think?

Later Addition: I have now done what I threatened and removed most banned words from the censorship function. I reckon our membership is mature enough to know when and when not to use the odd expletive. And I've edited your post above, Paul, to include the word you typed. Your use of it was entirely appropriate, in my view.

I'm with you on the kevlar thing. I reckon it's overkill. Just glassing ought to do the trick I reckon. And that can be a bastard to work with too, at times. ;)

I am up here in Kent staying with my in-laws at a very nice house which has to be locked up like a prison every time you go to the garden shed! Went down to Faversham yesterday to see if I could find any relatives of some of the lads that trained me 50 years ago. They were from this little creekside haven (they were re-directed by the war to Bristol) which had a ship/barge yard on its banks which had of course closed by 1970. I found some of the ex-employees running a little workshop on the quay making Wooden rigging blocks etc for traditional craft and carrying out repairs on some of the old Thames barges. The workshops however are to go because the land has been bought by guess what? a developer, and twee houses at £250,000 each are much nicer than a dusty old workshop! Anyway after much shared nostalgia (and mugs of tea) I went on my way out in to the gleaming sunlight of Mrs Thatchers brave new Britain. If you look up U-Tube Pollocks yard Faversham :tea:"sideways launch" a short but interesting film re the old trade.

I forgot to add that two of the ex-employees now (since 82) have a business manufacturing traditional craft fittings that are long gone from chandlery shelves, they can be found under "Colin Frake. Blockmaker" on the net. I am going to use one of their stemhead rollers.

If you look up U-Tube Pollocks yard Faversham :tea:"sideways launch" a short but interesting film re the old trade.Marvellous film which I thoroughly enjoyed. Wish there was more of it.

What a terrific range of products they are making. Not cheap but absolutely superb quality. I think I will have to buy some of that kit from them in the near future. We should support guys like these who are trying hard to maintain some valuable skills relevant to the kind of boats we all love.

Thanks, George. I have their website (http://www.colinfrake-classicyachtfittings.co.uk/index.html) saved in my favourites. :approval:
