A couple of weeks ago I have the boat out for usual servicing and a few mechanical tweeks and upgrades.
In the process and because the rubbers looked "pinched" and a little distorted, decided to change the cutlass bearings. So all the ancilliary stuff was removed the shafts slipped and the old bearings removed.
Now the boat needs imperial bearings so these were ordered from (*******) and sent in sealed boxes. New bearings fitted, shaftes, props/rudders replaced.
Lovely so boat goes back in the water...
First trip out, as I get out throught the lock at PS, noticed rather more vibration than I thought I remembered, but put it down to the usual "whats that noise/sound/feeling" when something is fixed... trip continues boat seems ok tracks through water ok... just my imagination..
Slowly get on to plane 18,20,25, seems ok but definately something amiss.. can feel vibration through floor..... throttle back and check shafts/ gearbox couplings etc but all ok.... off again 25knts, by 30 the vibration is very noticable... so throttle back to 22 knts and go look at the engines... port engine bouncing around on its mounts rather more than I think it should.
Get back to P.S. and have diver and engineer check the installation and props/rudder etc..all seem ok.
Only solution..... boat has to come out of the water..again.
Engineer working on it today and reports...
erm..... the port side has METRIC bearings fitted!!!! apparently the supplier has a batch of metric bearings that have been packed into imperial marked boxes... its happend before apparently! Incredible!!!!!
So who should pay for the lift/block/launch and labour?
Me, the engineer, or the supplier of parts?
