So we are having the boat anti fouled by a yard in which they have quoted, now today they have emailed asking if i want the thruster blades taking off cleaned sprayed 3 times with af , then refitted, all for £70 each thruster are they taking the P.

Since you are short of constructive replies I will add my thoughts. I have a Sepner thruster. Amazingly the blades are plastic and are really not very fouled. Partly perhaps because of the material and perhaps because they are in the tunnel, so dark. I gave mine a quick wipe...job done. £70 is ridiculous to my mind! Keep an eye on the anode.

You can’t really af the blades without removing them , here lies the problem, if they have not been off for number of years they can be a complete pain in the arse to remove , we had side power bow thruster and that had 2 blades, and ive spent well over an hour getting the blades off , then they need cleaning and new anode s fitting so I would say £70 is fair price considering the price of yard Labour

I recently did my own bow thruster changed anodes and painted the prop. Taking everything apart, painting and putting all back, side power with two propellers took just short of an hour. Also depending on how stuck on your anodes are they can be a PITA to get off sometimes so I think £70 is reasonable considering labour and material charges.

Agree.
Is that bow or bow and stern?
One thruster should be hr max. Anode around 13£ each.

Bow only. 2 props, Agree anodes + AF + labour. This time anodes came of really easily but previously have spent a good 20-30 minutes trying to pry off.

Yep, I bought a long pry rod with a hook end to lever the anode off (side power). Although the blades are usually pretty clean I take them off so I can af the tunnel. They are composite and get a couple of spray coats of trilux and a new anode

Get some boat handling tuition and you can throw the blades away
Such nonsense. You can’t make a boat go sideways without a bow thruster.

Anyway to the OP, the antifouling costs about £25 a tin and they can sometimes be difficult to remove.

So they are not offering a bargain but not really talking the P.

Take off the blades ?????
Load up the roller and wiggle it about a bit in the tunnel, certainly smothered the tunnel and everything inside with a thick coat of bog standard A/F in our case, then changed anode.

It’s a twin prop unit with minimal clearance between blade edge and tunnel, there’s no way I’d get paint in there

Sorry but would have to disagree with that. Using steering and port and starboard with in and out of reverse and forward does do it. A bit of a faf but could get you out of trouble if thruster packs in. Have practiced this myself in the event I needed to do it without thruster.

Perhaps Elessar only has one engine/drive. I would be interested to see you do that in a breeze. The video doesn't show it.

Yes I agree you can get a little sideways movement with the use of the wheel on shafts.
Eg rudder full right, right engine forward and left engine astern with a few more revs than the right and you will move sideways to the left.

Good luck getting that right when it’s windy and close quarters because it’s difficult to get right. Practicing is a good idea though so I’ll give you that one.

With outdrives you can move diagonally by using the engine the same side as the way the wheel turned about 20 degrees. Eg wheel right and right engine. (The exact opposite of what you do when making a turn)
Which is why in an outdrive boat you use the engine nearest the pontoon and steer towards the pontoon to pull out forwards and move sideways away from the pontoon without rolling the fenders out.

This is easy just a matter of learning the amount of wheel your boat needs. But the sideways component is limited and so call it a draw - you won’t get that to move sideways in any sort of a breeze.

Agree with you both. Sooner or later I may have the loss of a bow thruster for whatever reason and sods law it will be when it's blowing. It was blowing when I practiced, it was not easy but manageable and did get some control moving sideways albeit slow but it's not something I would want to do or look forward to doing in close quarters but at least I know that it can be done and hopefully get me out of jail if needed.
