Shaft maintenance

[njrickard]

Hello all , I have just received the quote in for works on my Princess 470 and would appreciate your feed back on the price, i feel it is reasonable ? or is that just me owning boats for too long !!!

Purchase : Four (4) elastic bearings Φ 44.45 m (1" /4), 73.00 X 4 = 292.00 Euro

Propeller Work: extraction, pitch control, electronic alignment, polishing = 250.00 Euro

Other Work: Shaft extraction, check on lathe and alignment / gaskets extraction & replacement / bearings (4) extraction & replacement / rudders (2) extraction & replacement = 1.400 Euro

Total = 1.942,00 Euro

Regard Nige

Its not a million miles away.

Add lift out and re launch and yard rent.

Removal and refit is a two man job.

I know what polishing is,

Pitch control not easy for anyone other than a professional prop shop/ prop manufacturer.

Electronic alignment, I assume is engine alignment, not strictly necessary unless there is a problem.

Thank you Bandit for your input, she is out for a couple of months for anti fouling , polishing etc so thought as there is no history of this being done i would do it, so just ticks a box in my (ocd) head

regards Nige

Electronic propeller alignment involves taking lots of measurements across all the blades of the prop. Can't remember the name of the tool, but seen one at Boeing used during aircraft production. It's like a robot arm and moves around the faces of the blades recording all the coordinates (x, y, z) in predetermined places along and across the face of the blade. Any difference between the pitch / profile of each blade is balanced.
