Lister vibration
Arthur Marshall
having a leak sorted... but apart from that, what I've got is a lot of
vibration at slow revs (Lister SR2, aircooled). It's fine on tickover
and fine at about 3 mph but anywhere in the middle and the whole boat
vibrates which I suspect is not doing anything much cop.
I know the fuel filter needs changing, but I can't see that would
explain it, so any other possibilities leap to mind? It's got a
flexible coupling and a new propshaft.
After about 3mph, it doesn't speed up much however far forward you whack
the control lever, just adds more black smoke to the exhaust. If it was
a car I'd suspect the clutch as slipping - could this be it? And if so
what do I do about it?
The whole engine got a major overhaul about ten years ago so I should
have thought it should be OK for a few years yet. Oil gets changed twice
a year...

An obvious one, Arthur, but are the engine mountings OK? Sometimes a
broken bolt is not obvious when the engine is stationary.

Bolts are OK but the vibration is taking its toll! I broke three last
year. Mind you, i suspect they had ben there for about forty years, so
it's reasonable they should all go at about the same time. New ones are
fine.
Nothing round the prop.
Mind you, the leak I've got is at the point where the propshaft comes
through the hull. I have no real idea what goes on round that bit of the
boat, so I suppose if whatever it's stuck to is coming loose the prop
could be flailing round a bit.

Can you check the prop for security, or a broken or bent blade, or
even a slightly bent shaft just in front of the prop? Any of these
would make leakage through the rear gland seal worse.
I once had a motorcycle head gasket firmly wedged around one of my
blades. How it got there I have no idea, but that caused considerable
vibration and rear gland leakage, very noisy cavitation too.

This weeks prize appears to go to Tony - according to boat doctor who
was stuffing weld down the rust holes in the back of the boat, the prop
was a bit loose. He said it was something to do with the
forward/reverse gizmo - does this make sense to anyone out there?
Anyway, he's tightened it all up and reckons it should be better... I've
had the thing blacked while it was out of the water so I'll know
tomorrow.
Glad I'm not picking it up today - weather's horrible.

Hope it's OK. Is it still PC to say 'blacking'?

It's still floating and no drops, apart from the steerer.
Not sure about blacking, though. Colouring would be worse.
PC has it's points, but until they make pink bitumen...

I'm sure Brian Holmes would be interested when they do :-)

That would be an interesting pole. If there was an alternative colour
to black for blacking the hull, what would we prefer?

Don't be silly, you can't black the hull with anything except black
because then you wouldn't be blacking it. Purpling it would be
ridiculous.
Anyway, black's a REAL man's colour, even if it isn't really a colour anyway.

Black *is* a colour - so are pink, blue, brown, green and yellow.
Red is not a colour.

My indecision is final.
krystyna@googlemail.com Mike & Krystyna Wooding
Disagree here John, Black is the absence of colour. Black can be referred to
as an achromatic 'colour', but is essentially the 'colour' of objects than
do neither emit, nor reflect light in the visible spectrum, but absorb all
visible light frequencies.
As for red, if it is at a wavelength that is visible to the eye, then it is
a colour.

I was about to point out that black is "no colour as in no reflected light"
when I read your comment again John. I'm now forced to agree with you that
black is a colour :-)}
However white is all colours!
