Joking aside, it could be one of several things. I'd be inclined to think not filters but, by giving it a service that's due anyway, you'll hopefully get there by a process of elimination.

Could valve timing have anything to do with it? Nearly 400 hours on the engine and I can't see 'valve timing' on any of the service receipts?

Alt, valve timing is not a service procedure. It is set as the engine is built and it is usually non-adjustable anyway. However, setting the rocker clearances is a service prodedure and it effects the valve timing. This is also commonly known as setting the tappets. This title is a hangover from the days of sidevalve engines. The topic was covered in your other thread. If it hasn't been done, it's well overdue and it is important.

j - Half asleep here sorry. I meant valve clearance. Another thing to get checked out on the weekend. Not going to try it myself - it's times like this that mechanic friends become useful

Hi guys,
Serviced the engine today. Engine oil, oil filter, crank breather, air filter, coolant, fuel filter, bled the injectors etc (Yet to do gearoil/anodes) and unfortunately, no change in RPM.

She stops at 3000RPM. I tried WOT in neutral, she storms to 3000RPM and then just stops dead. Same when under load, on the plane in less than 3-5seconds, and just stops at 3000RPM.

Before thinking that the turbo has gone, could the engine possibly be limited? The reason I ask is because, as I said before the engine storms to 3000RPM and then just stops, doesn't even try to go further. I would think that even if the turbo WAS gone, the rev's would try and rise (When not under load - in neutral)

Another thing that got me thinking, could the tachometer be lying to me? I'm no diesel expert but when I open to WOT, the engine sounds like it's roaring away. Roaring to the extent that thinking of adding another 900RPM to that roar i'd be expecting a cylinder to pop out of the block.

Suggestions people!

Check the back of the tacho and see if it has either a rotary switch or dip switches, if it has make a note of the present setting, then with the engine ticking over change the settings to get the tacho giving a higher reading.
Open the engine up and check that the tacho goes to more than 3000rpm if it stops at 3K then the tacho is sticking. If it goes above then it should be ok.
Also it is worth checking that the rotary switch or dip switches are set correctly for your engine.
Richard

Is it an EDC engine, my first thought was blocked fuel filter (does it have a pre filter, Racor) if not, the engine, if EDC has various limiters affecting revs if something goes tits up.

Incedently,if your boat is getting on the plane with enthusiasim shall we say, the prop pitch is, fine look elsewhere.

Alt, that's kinda good and bad news. Here is the setting procedure for your tacho. In the code table, you can see that on some 32s there must be an alternator driven sensor and on other 32s its inductive. You will need to find out which yours is. Depending on this, your code will be either 8 or 17.

In the setting procedure, you can see that at stage 3 you will be able to read the previously set code. Hope that it's incorrect.

Apologies for the elongated stage one, it skidded in the scanner each time I tried it.

Edit; I see the text is not very clear for stage one. It says,"Disconnect from system voltage, press in pin B."
