I think I need to do a cutlass bearing, port engine stalled a couple of times going into gear, shaft seems tight to turn by hand, I haven't slackened off the coupling yet to check, but I suspect the cutlass bearing needs replacing, no idea when I last did them. I found invoices for 2 over the last 12 years.

Brass or phenolic resdin body, what are the pro's and con's?

Can I put a phenolic one in a bronze P bracket? Any benefit in doing so?
 
Welcome to my world ! Phenolic can swell in the housing making future removal difficult, but apart from that not a lot of difference in functionality. A good local supplier is CC Marine at Universal, Sarisbury Green, or Aquafax in Ensign Way. Measure accurately to determine if imperial or metric, although for your Fairey I would expect imperial.

Your puller was great at pushing mine out when I borrowed it after it had got the prop off. Let me know if you need a hand.
 
Thank Trev.

I bought them through Hamble Props last time, Aquafax do have them, I'll call them in the morning, they are imperial, 1.25 by 1.75 by 5" long.

I might ask if HYS can leave her in the slings one evening and see if I can do it.
 
Shell material does not matter if going in a bronze housing. Brass shell, however not sensible in steel or GRP tube.
 
Measure twice and check again.

I fitted a new set last week and only found after going back in the water they are the wrong size. Measured the outside as 2 3/8" so assumed the inside would also be imperial so went with 1 3/4". Now find that the outside is right (or they would not have fitted in) but the inside should be metric - 45mm.

Boat coming back out again today for the right ones to go in.

An expensive mistake :disgust:
 
Just to save confusion you are talking about rubber bearings in different sleeves, you can also buy phenolic composite bearings. These are solid composite, the bearing surface is composite a blend of fibre resin and lubricants. They look like this...

The sleeve as others have said makes very little difference but it is very important you get the right size, we insist on knowing the ID of the bearing carrier as we work on clearance fit so we can finish the ID accurately to suit the shaft. A press fit can be an easy press or a tight press and this will squeeze the ID of the bearing thereby changing the running clearance.
