Hi, The cutlass bearing on my 1999 SO 34.2 only lasts 1-2 seasons so I am planning to use a different type of bearing. Could anyone please assist with the exact outside dimension of the standard bearing i.e. the bore of the P bracket?
Thanks to all
Makemyday

Hi Makemyday,
A likely cause of cutlass bearing short life is engine misalignment. When you get the boat back in the water, and after any rigging tension adjustments, get your mechanic to carefully check engine alignment. An indication of bad alignment is a tingling feeling under your feet when at the wheel, but this depends on your having experienced how smoothe a boat under engine engine feels with good alignment.

Hi, thanks for the input, but alignment is good. I run a Seahawk Autostream s/s self feathering prop that is heavier than standard prop and maybe 25mm prop shaft is on the light side, plus a cutlass bearing that I feel could be improved on. Therefore I need the outside diameter of cutless bearing to source a new type to have ready to install when I haul out the Boat,
Cheers,

I don't have the info to hand, but if you contact Pauline at www.sea-ventures.co.uk/ they will be able to supply the details as that is where I got a replacement at a good price (£20) three or four years ago. Repeating the above comments, for it to last only one or two seasons, there is something wrong. |

Some manufacturers bearing dimensions are based on the inside diameter of the bearing carrier, this should be measured after cleaning and the new bearing will be supplied as either a clearance or interference fit to suit the carrier.

Hi, thanks for the many replies. Following up on the comment by ianqv I think that the weight of the Autostream prop accelerates the wear on the Jeanneau rubber cutlass bearing and a composite type bearing will give longer life. Therefore I still need the bore size of the P bracket (bearing carrier) so I can have the cutlass bearing pre machined to size ready for haul out.
Cheers makemyday

I too have a 3 bladed feathering (v heavy) prop. I was interested to see how the bearing was doing.... So I dived under the boat the other weekend. I'm pleased to say that I have no play in the bearing!!!! Also.... my ultrasonic antifouling is working v v v well indeed!!! Makemyday - speak to the guys at H4. They are very helpful and will sort you out a bearing to fit. Top tip - take time after fitting the bearing to align your engine so that your prop is central. Then once you have launched... align it again. Putting the extra effort in now means you can fit and forget about cutlass bearings!!  If you need more info drop me a pm with your phone number Regards Ian |

Hi all, thanks for the replies. Contacted sea ventures who sent my inquiry to Jeanneau. Jeanneau just sent back the part number and cost for cutlass bearing, Sea ventures then sent an email asking for the bore size of the P bracket. Return email gave the part number and price for P bracket. Jeanneau do not seem as though they are interested in helping owners, just selling spare parts. I guess customer service or tech help are not in the French language. Will just have to wait till I haul out and measure it myself at the cost of a longer haulout and added cost. Thanks Jeanneau!

Hi, slipped the boat yesterday and pulled out the cutlass bearing. The bore of the P bracket measured 1.437 inches (1+7/16th of an inch) or 36.49 mm. Well done Jeanneau to combine metric and Imperial measurements to make things more confusing. Now have to wait a day or two to get cutlass bearing machined at $70 a day because Jeanneau were not prepared to supply the information. Many thanks to all on the forum who tried to assist.
Cheers magnum
