The only reference I can find to limiting the revs, if the EDC finds a fault, will limit the engine to 1000rpm. This will also show as a diagnostic error on your display with the wee buttons. However, depending on which system you've got, if you switch off the ignition the error code will be erased from the EDC memory. It's worth noting this for future because should you get an error while under way, it's all too easy to switch off the engine and accidentally cancel the code. It seems a daft feature to me.

I would be surprised though if there wasn't a maximum rev limiter built into the EDC system.

In my opinion all this 'fiddling' about with second hand info gleaned from Ribnet is costing you time and money. If I were you, I'd get the thing to a Volvo Penta agent, get it diagnosed and sorted. You could mess about with this, that and the other for weeks and then pay more money to have the 'fiddling' put right.

Morning guys, fingers crossed it's the wrong setting, i'm off to give it a try. How the heck do I know if the engine is picking up the RPM from inductive or from the alternator?! I guess i'll just try every setting and see what happens. Watch this space!

KAD 32 is not EDC, as far as i know - mine was'nt.

I had a prob, when new, that after a while the revs started to drop, and went through all the panic things - turned out the cable to the throttle nut was loose, and was working is way 'out' - so was not getting full revs - easy as that.
Way to check is get someone else to steer, open the engine box up, and give the throttle linkage a tug -
Is the compressor going off when motoring?
Any black - unburnt diesel in the wake, as you are going along?
if you have a pre filter - racor, whatever - did you change that?
Did you ask the prev owner what his cruising revs were, and make sure he has not sold it with the wrong props on ? if he had dinged the originals, there is nothing to say he did not pick up the 1st cheapest set to bung on to sell it, and might be the wrong ones ?

Problem Solved!

I am so relieved! Went to the boat there, and she was idling at 400RPM as is

I changed from setting 17 (Inductive) to setting 8 (Alternator), fired her up and she was idling at 725RPM. I let the engine warm up for a few minutes, varying the Revs. Just to check, when she was warm I opened to WOT in neutral. Straight up to 4100RPM!

Guys, I owe ye all, ye are total lifesavers. I was worrying about turbo's, fuel pumps etc. when it was such a simple thing as pressing a friggin button!

jwalker & rickuk3 - If I was a girl i'd kiss ye... Now where who should I send the keg of Guiness to?!

Moral of the story - When there is a problem, check the basic stuff before worrying about the expensive stuff!!

In fairness the boat hadn't been out of the water in over 12 months (He had nowhere to dry dock her, and no trailer). I now think that the propellers on her are the proper ones, and we have a written aggreement that both him and I will pay 50% each for new props (He keeps emailing me asking which ones to order - so im guessing he's genuine!)

Well done Alt.
Apology from me though. When you mentioned the tacho a few days ago it just didn't come to mind about having to set it initially. So Richard can have my kiss for his suggestion.

In fairness Mollers, had I of gone with your advise above:

1) I'd have had to pay someone
2) There are no Volvo mechanic's in my area
3) I wouldn't have learned anything

I feel good being able to fix a problem myself and I have learned something. Big up to the RIB.net guys!

In fairness Alt you were lurching about from one ridiculous theory to another. You were lucky that it turned out to be something trivial.If it had been something more serious, a relatively cheap professional diagnosis may have stopped you from changing practically every ancillary component on the thing. If you employ the services of a professional and listen to what he has to say, you learn from someone that knows what they're talking about. Let's hope that you don't get a serious problem with the boat, as your not having a VP agent in the area and your lack of knowledge are going to combine to leave you up a creek sunshine. And, if someone in the future offers you friendly advice, take it in the manner in which it was given.
