Fairline Squadron 55 MK 2 2009 MY – Advice wanted please

I guess this could go back to your comments in response to my earlier posting, if the hull extended further back as in the 58 MK2 that might solve the problem, interestingly she doesn't look so bad in this vid

but maybe she had full trim on then. Also until I can test at full RPM I wont know just how much more natural lift will be produced by the increased speed
 
Thanks jrudge clearly there is an issue with the CAN bus system I thought it was just the Pilot system. Located in the lazarette this boat has 2 x 370 ah batteries attached to a big tin box on the port side to which is also attached the aftermarket Victron charger, on the centreline there are 2 x 270 ah batteries, I couldn't see a third battery. Do you have any knowledge of a fix/upgrade for the Energy Solutions setup or does the whole lot have to come out and start again?
Other points noted particularly the last one!

If it is the touch screen system then I think it is terminal. Most were replaced by Fairline. It was clever but so unreliable and they ( energy solutions) could not fix it. Other may know different

Re the can bus system in general I can be fixed cohere are two parts the master module at the lower helm ( also called the timing module) and if that goes all systems can only be turned on by pushing a small button on each distributed unit which then turns each item on

Each distributed / local module controls circa 4 circuits. If one of those goes faulty then you buy a new one from energy solutions. Each is coded by them to its position in the boat so it takes a bit of time for them to arrive

The oem batteries are in the base of the lazarette ( or were in the 65) the big tin box is usually the 24v high power switching gearc
 
Thanks for the P46 accolade I totally agree and wonder why I'm upgrading. The SQ55 had an engine less small RIB I guess about 75 kg.

I think comfort and space wise it is another ball game with the 55 versus the 46. Normal weight, so that boat should be able to do 30 knots WoT, taking away the engine problem.
I think the aft lift is normal in a boat of this size and type, and in the MBY video it looks worse cause they are filming from a low platform or a smaller boat.
The second video from the broker looks her running nice and not very fast, about four degrees bow is pretty good at what looks 22 knots cruise.
 
That rpm issue could be a huge expense I am a Volvo mechanic. Avoid unless it’s an absolute steal. Do you mean the flex plate has been changed? It’s quite common they need changing. It’s not that difficult if the engine room is ok.
 
Good to know that there is a fail safe option on the CAN bus system, I am getting a full survey carried out on all the electrical systems as clearly I am ignorant to this boats complexities.
I thought the tin box and its batteries was a 240 v invertor to deal with refrigeration and other AC systems except the aircon didn't realise they used local invertors.

Thanks again for your help can I pm you if I need more please?
 
As I've said I had a delightful trip on her for six hours 1700 rpm 19 kts full trim but smooth pity I couldn't check the fuel flow, log was u/s!
 
Thanks vptech the engine would rev beyond 1800 but we didn't maintain it as the 'Air Temperature' warning came up on the display suggesting an air intake issue the surveyor checked the temp (I don't know where) with his gauge thr bad engine was 10 degrees higher at 56. I'll find out more after an OEM survey.

Point taken about the flex plate no signs of a problem on the other engine, will keep an eye on it.

Feel free, do however bear in mind my direct experience is based on a S65 which whilst it will bear many similarities will be different.

Re inverter etc ask the vendor. Fridges are usually 240/24v so no inverter required.

If it has the touch screen system I wold confer with others and contact Energy Solutions to confirm they will support it before buying.
 
The rubber drive couplings between the engines and gearboxes do fail, we’ve replaced about 6 on different boats now.

On a D12-800 engine high air inlet temp is normally caused by the coolant system being topped up with the wrong coolant. Inspect the plastic cover over the charge air cooler to see if it is deformed. The D12-800 uses Volvo’s yellow oat coolant and cannot be mixed with anything else (especially Mallorca tap water). The coolant system needs to be drained and flushed with oxalis acid.
