I doubt it's the amperage, if anything it's more likely to be the voltage. They use Optimas in Europe attached to inboards with 180A alternators.

Hmmm! who told you that one? Mine are fine after 5 years. The battery will only take the current it needs. The blue tops are deep cycle so are able to handle deep discharge & repeated charging.
Glad you bottomed out the oil problem, care to elaborate?

Wait 'till you see inside the console

Well it was told to me by our dealer friend who is doing the work. We had suggested to him the Optimas decided on using this thread and whilst researching them and whether they would be suitable he spoke to his mate somewhere who said he had had three etec powered boats fry optimas within three years but that they were ok for verados due to the lower output may be cobblers.

Well... Because the auxilliary power cable is being fitted we took the opportunity to swap the horrible grey sewage pipe out for a proper etec cable duct...whilst doing this swap it was discovered that the big pipe was full of oil...upon further inspection a big patch of gaffer tape was discovered wrapped around the oil pipe which (dun dun duhhhh) was unravelled to reveal a little plastic connector to join the oil pipe...basically...the oil cable was too short so it was extended using a tiny dia bit of pipe without adequate joining so it had leaked everywhere! No wonder there was no pressure in the system... so the front of the engine is in pieces as a proper length oil pipe is being fitted... Roy did cut some fantastic corners when fitting out our Into the Red..

The fuel cable also had the same kind of join to a small dia pipe, so out that goes too...

I have no desire to look inside your console ever again. Fixing your BNC was enough

Mmmm porkies being told by someone. Verado has a 70A alternator !!!

But how much of that is dedicated for charging the batteries? Etec has a 140 amp alternator but only 55 is used for charging batteries.

It is all set to change don't you worry

[Erin]

So where's the other 85A going then?

All etecs come with a length of oil pipe coming out of the engine with a plastic joiner fitted. They use a metal clamp (oetiker type) and a small plastic joiner to connect to the oil line from the oil tank. Same goes for fuel line.

Sounds like the clamp was not fitted correctly if there was a leak.

No, it was worse than that. This was an intermediate extension piece before it reached the engine apparently. He seemed to give the impression it was basically the gaffa holding all the pressure in...

If Osprey want to start selling a few more boats then the standard of factory fit out needs to be improved significantly, which I think is in the process of being worked on

The trouble is, most manufacturers seem to suffer with 'can't be arsed' syndrome on the part of the people fitting the hulls out.
You can build the best hull in the world and ruin it with 5 minutes of laziness or 5 quids worth of pennypinching.

To go back to the original point of this thread, since the Optimas have been ruled out (rightly or wrongly), need to find some batteries. This one: Numax CXV24MF Heavy Duty Maintenance Free Leisure Marine Battery 86 Ah 900 CCA | eBay that DHD recommended on another thread looks good and fits in the red box which is what I want. Perfect for the starter battery, but what about the house...is that not sacrificing Ah for CCAs? Can anyone recommend a 110ah that fits in a red battery box?

[Downhilldai]

I doubt you'd get a 110Ah battery to fit in a red box. You could run 2 of the CXV24MF batteries, in which case you'd have a decent starter back-up, should your main one fail. Nice bit of insurance. Do you anticipate much deep cycling of the aux battery, eg running an anchor light overnight, or lazing around at anchor with a cool box running off 12v? (don't ask how I know about the latter.......)

Not really..but it will be used for powering the bilge pump on the mooring

is there a link between cca and ah?

Yes. Generally the plates are larger and thicker to cope with high CCA which reduces their surface area and therefore Ah.

IIRC I have a basic leisure battery (squadron SFL) in my console which sits happily in a red box. Pretty sure it's 100 or 110Ah. Never been a problem yet with it sitting on the mooring operating the bilge pump and also starting the engine.

Finito!

It has been very well done except the batterys are mounted to port thanks to a loss in translation

Will be interesting to see if it will be worth the hassle of moving them during a sea trial tomorrow.

"Batterys"? People in glass houses. Here's me thinking that you're effluent in several langue
