Victoria 34 prop/shaft mounting arrangement?

Does anyone know what kind of cutless setup a Victoria 34 uses? Blue Opal has an arrangement that I don't know the name of, and thus can't search for:

I'm starting to hear a noise when the engine is under load (and only under load) that varies with RPM, and sounds a bit like a thrum/rumble/knock. An uninformed guess is that it's the cutless bearing, but I need to know what kind of fitting I have so I can do more research smile

Duncan,
I am just in the process of having my cutlass bearing replaced, on my Frances 34, and I can get the details from Vortec Marine, Universal Marina on the Hamble, who are undertaking the work.
Removing the old one was something of a trial but managed in the end. 
Jon.

Re: Victoria 34 prop/shaft mounting arrangement?

That would be much appreciated Jon, especially if yours looks like mine! I suspect if I want to remove mine, I'm going to need to drop the rudder - was that true with yours?

Hi guys,
As I have my propeller removed pending the delivery of my new one, I intend removing my cutlass bearing for inspection too.
The setup looks almost identical to yours Duncan.
I wouldn't have though that you need to remove the rudder as there should be enough space between the end of the shaft and the forward face of the rudder.
I'll provide an update within the next few days all being well.

Kind regards,

Charlie.

Re: Victoria 34 prop/shaft mounting arrangement?

A bit later than planned and perhaps you have already had your cutlass bearing sorted Duncan?

Paul will attach some relevant photos, but between times, both my and William McCauland's V34's have identical cutlass bearing hardware. Both boats were built in 1990, so that will obviously carry some weight to them both being the same I guess.

Based on some info from Darglow Engineering, several V34 and Francis 34's have slightly different arrangements which include longer shafts to accommodate rope cutters.

In our cases, the cutlass bearing assemblies can be removed off the end of the prop shaft without needing to remove the rudder (or engine if you prefer to withdraw the shaft internally).

Anyway, the prop shaft on my V34 is 25mm in diameter. The cutlass bearing has an inner diameter suited to the 25mm shaft and an outer bearing shell diameter of 40mm. The bearing when housed in the bronze casting is only 50mm. The standard bearing length is 100mm.

I had to cut through the bearing using a large hacksaw as there isn't an internal lip available to press or drive the old bearing out, i.e. it is flush internally with the wall of the bronze cutlass housing (I hope this makes sense??).

I greased and pushed the new bearing into the bronze housing and then tightened the 2 grub screws. I then used the large hacksaw with some 'Rocol' cutting fluid to remove the protruding 50mm worth of bearing.

The pictures should help.

I should have said the two bolts that secure the cutlass bearing are easily removed, however, a large stilson spanner will be needed to remove the cutlass housing (rotates anti-clockwise when looking end of from the propeller or stern) from the end of the stern tube.

I hope that this info is of some use. :-)

Kind regards,

Charlie.

Re: Victoria 34 prop/shaft mounting arrangement?

Thank you Charles, that's very helpful, and I can pass it on to the local yard. I've had the rough estimate from them, and they've not met this bearing assembly before, so being able to give them some info will help.

Re: Victoria 34 prop/shaft mounting arrangement?

Looking at your first picture and last picture, I take it that's the "forward" part of the assembly that's bonded to the hull with bolts and sealant? I'd be a bit worried about putting a hacksaw into it to get some grip, solely because it weakens the bearing a bit (not that there should be lateral load on it).

I'm also curious what change you were making to your propeller smile

Re: Victoria 34 prop/shaft mounting arrangement?

The two cutlass holders above do not look the same.   Charles's looks the same as the one on my boat, but Duncan's looks as though it is split half way along - undo the two machine screws (should be bronze bolts) and half of the holder comes away.   The Cutlass is held by a grub screw or bolt either from above or below, and can then be pulled out - ie the holder does not need to be detached from the stern tube in the same way.

Re: Victoria 34 prop/shaft mounting arrangement?

Good point Jonathan. I think the prudent course of action is going to be to lift the boat out for the scrub and anti-foul, and disassemble the stern gear at that point, measure everything, and order the replacement bits. It'll mean a hard-standing charge, but it's probably better than ordering a bit that doesn't fit right. I'm fairly confident that the shaft diameter and bearing diameter are not different, but there could have been changes in equipment depending on what was available at the time. Either way, it'll get documented, and posted here/on my blog.

Re: Victoria 34 prop/shaft mounting arrangement?

The stern gear on my V800 was identical and the shaft was 25mm dia. It had Vetus stamp on it. I took it to the Vetus stand at Southampton boat show but none of their reps recognised the design. It was removed because I had a serious leak from a cracked stern tube. When I pulled the sterntube it was made of thin wall tube and as fragile as an easter egg shell.  It was easily pulled apart without tools! The cutless bearing had to be cut out of the fitting (1" /25mm mismatch).
I have replaced stern gear and tube with far more robust made-to-measure gunmetal fittings from Sillette-Sonic Ltd [Type 1]. On the inboard end the fitting was sized and machined to take a Volvo shaft seal. Now I just have to trace a deck leak and I should have a dry bilge!
