Any Blue Star owners out there ? I was sailing mine last week and it sounded a bit noisier than usual which I think is due to lack of lubrication. I think the jet drive unit is actually a Kehrer KMB Jet 28 - can anyone confirm this please ? If so the KMB 28 instructions say the impeller shaft can be lubricated through hole A where it says there is a grease nipple which I cannot detect . I do not want to have to disassemble the drive system if I can avoid it. I will be very pleased to have  any advice and / or experienced comment.

Can you post some photos of the drive unit?

mine did this. found out the one of the bearing had rusted up and worn out. replace and ran a dream again.

Martin a photo wouldn't show the detail. I've attached a diagram of the unit.
Thanks

I've had to compress this photo to get it onto the site

The bit labelled 'Schmernippel' is through where you apply grease to the prop shaft.

Thanks for your reply, how did you go about it ? . Did you access the bearing by removing components from the stern end or take the motor out? I fitted a new motor in 2010 and I remember it as a very difficult job.

Hi Sonparc,

I had to remove the motor (which took forever due to one of the bolts).

After removing the prop I knocked the bearing out. when putting it back together I put a tube where the small hole is on the outer casing for oiling.

I have a spare prop i think if needed.

Just a thought, I found Kehrer very good at supplying spares ordered from their web-site.
