Radice Seal

[masterman ready]

I have just replaced my stern seal which was a deep sea seal which was leaking quite badly when the engine was in use. the boat is out of the water and I have fitted a Radice seal. Installation has gone fairly smoothly, measure the shaft and ordered the appropriate seal. used fairy liquid to aid installation, I did find it quite difficult to remove the seal protector and had to redo it as I couldn't get it out the first time.
I find that turning the shaft by hand from the outside of the boat that it is quite stiff, I gauged this against other yachts at the club. Wondered if this is normal to start with or cause for concern, I have greased it with the supplied grease.
thanks in advance for any views.

Are you certain that you measured the shaft size correctly and did not confuse metric with imperial sizes?

I certainly found it hard to get the protector out when I fitted mine, but did not find it stiff to turn. Is it definitely resistance from the gland or could it be the cutless? Is the alignment good - especially centred in the stern tube?

I’m pretty sure I got it right but am going to double check it.

Thanks, I think I am going to have to remove and have a look

What size is your shaft?

Tightness may indicate a 25mm seal on a 1" (25.4mm) shaft for example. If it is the correct size greased it should not be difficult to turn the shaft.

I've had a Volvo seal for 12 years 1500 hours. It's quite stiff to turn the prop out of the water. . The Volvo seal has a cutlass type bearing in it. Not sure what stern tube bearing you have but if you also have a cutlass in the stern tube like mine it will seem quite stiff out of the water. I wouldn't take it apart again.

On the back of your post, I fitted a Radice seal last winter, I moved the shaft today. It was stiffer than when I had the other seal.

Thanks for all your posts, I remeasured the shaft again today and it seems I have installed a 25 mm seal on a 1’’ shaft, so have ordered a new seal. Muppetry by me !
