Hey does anyone know if the bow thruster on a 2008 B40 is a  Max Power CT60 or CT 80.????

We had to change out the macerator's Marelon seacock/thruhull in the forward head in 2013. Like yours, our's started leaking constantly. No issues with salon macerator thru hull. I've read where others having gotten 25 years of usage with the Marelon so I was really surprised our's failed after only 5 years.

James, I too have a 2008 B43, with Lifeline AGM's since new. So far they are performing fine.

Agree totally on AIS usefulness. We spend much time transiting major shipping lanes with commercial tows. It is great to be able to specifically call them and agree on ,meeting and passing intentions.

I just changed out the forward head thru-hulls and valves to address a slow and insidious water intrusion issue. I was finding water under the fwd head pan (not from shower, fresh water tanks, etc.). Seems to have addressed. All else seems to be holding up well at 7 years.

Pretty quiet out there!

Just replaced 7 year old agm batteries in our 08 B43. No complaints. The solar panels kept the batteries peaked. One of the 4d"s began to overheat as the charger tried to raise voltage to 14.3. Internal resistance due to sulfation I guess. Replaced all batteries with new agm's. Stevens Battery Wharehouse in Pasadena Md has great pricing on batteries Dekka 4d $339.95 vs WM $699 for same battery.

Installed AIS receiver last year, love it! Overnight passages in Bay and Ocean much easier now that we know who to call and identify ourselves to.

08 B43 is holding up pretty well, no real issues with boat.

Hi Everyone,

Just grabbed a mooring at Man-O-War in the Abaco.  Great sail in 30knt winds the boat stands up well.  I did notice when I went below that there is a foam backed plastic apron in the forward cabin that covers the screw nails of the hull deck joint.  It had fallen down and when I tried to push it back up the foam backing fell off in patches and it wouldn't stay.  Has anyone had this problem and more importantly, does anyone have  solution.  I tried double faced tape but it will not stick to the vinyl and is really not the answer.  It seems that Beneteau just pushed the vinyl up and hoped it would stay there.

Any suggestions welcomed,

I could not find the original ones. I bougth a pair of Navsound Speakers that could fit in the 11,5cm hole cutout but they started to "distort" just after 1 year of operation. Also they were not "loud" as the originals. So the first thing I have done as the season closed was to look for another pair. I was not able to get replaceable speakers since all that I founf needed a larger hole cutout. So I made a 12,5 cm hole and then I got a pair of 5 inches Boss Marine, They are not very expensive and sound good!

Regards, Luis

Has anyone found a replacement externat speaker for an Oceanis 40?  Ours has fallen to bits!

Hello Frank &Donna,

Happy New Year and fair winds.

Winter is a good time to install some in cabin items.Did you fit a Seagull fresh water filter from General Ecology ?

I have a hard time finding the best spot to have the filter exchange easy.

Any suggestions would be welcome;

Thank you

I have no idea!

Maybe you can call Beneteau with your manufacture's Identification Number and Beneteau can give you the hull number.

battery life

I installed Lifeline AGM batteries upon commissioning the boat when new. I used GPL 27T's on the engine start and bow thruster service. I used the 6 volt GPL 4ct's in the house bank ( total of six, 660 amp hour capacity)I just had to replace both of the GPL27T's. Boat was commissioned in July of 2008, so a bit over 7 years life obtained from those two. Hope to get at least a year or more from the house side, as they have been managed carefully.Just data for those interested,Sams/v LONGHAWKI B43…See More
