Morning all

Thanks for your input on this topic, the engine was re-built 3years ago and I don`t like

tempting fate but its a happy little thing. I don`t think the last owner took her out

very much, just liked to work on her and sit on board her relaxing.

When I put it into reverse I thought the noise could be dinner plates or cutlery

vibrating, so I moored up, moved all the plates and cutlery away from the dinette

storage area and tried again with reverse gear and low and behold it was`nt the plates and

cutlery vibrating . The noises are comming from the gearbox area or so my dodgy ears tell me.

I don`t know if I have posted this in the right section, new to this site but here goes.

I have recently bought a ormelite cruiser ( built in 1968 ) and it has a wortham blake engine

and gearbox fitted. I have checked before and after trips the gearbox oil level and there seems to be

plenty of oil in the box, BUT it sounds very un healthy , ticking and clicking at low revs and sounds REALLY bad in

reverse.

Is there any one out there who can give me tips, info into sorting this problem ( if it is a problem, maybe it should sound this way )

Any help please, as I don`t want to set off on a trip and find I have to break out the oars to get home

Does your gearbox have a reduction box fitted to it ? If so, a badly worn chain and sprockets could be the source of the noises. I think that some Wortham Blake (although it might have been 'Watermota' - it was a long time ago!) reverse gears were supplied with duplex or triplex chain reduction boxes instead of the more usual pinion and reduction wheel set-up. It is easy enough to establish whether it is a chain or a gear equipped box - just check the rotation of the reduction box output shaft/half coupling - if it is rotating in the same hand as the engine crankshaft in ahead gear, then you have got a chain equipped reduction gear.

Thanks for the advice, I`ll have a look at that when I get to the boat this weekend

During my youth, the recommended way of curing gearbox noise (immediately prior to selling a car) was to add sawdust to the gearbox oil. If that didn't work the chopped banana skins were reputed to work. 

Not sure if this will help the OP though.

As promised , here are some photos of the noisy gear box

Sorry if the photos are not up to scratch, but it was cold. I was shivering and I was being pushed around by an irate dog !

Hope you can find something in the photos to point me in some sort of direction
