Ok

So i will keep it short, but i have got a Bayliner 288 with a 2005 4.2 D-Tronic 250hp lump, runs fine, but seems to be limited to 3000rpm, even in neutral.

From research it sounds like an electronic limiter when it has a fault with the No.1 Injectors Need lift sensor.

So great, just went to go buy one and then saw the price tag of $1400!!!!!! for 1 injector, $1400!?!?!

what planet are Mercruiser on, its a dam injector, i really cant see how they can justify the cost for just 1 injector, really pissed me off as I feel like I am actually being ripped off, $320 for a standard injector or $1400 for a sensor version.

I need to go get a drink!
 
Lots of things on that engine invoke a rev limit, you need a Rinda tool to find out what one. The number 1 injector has the timing sensor built in, I would say it's unlikely that's the problem. Try the MAF sensor first and also check the oil level in the drive, there s a float sensor in the drive oil tank, if that's low or stuck it limits the engine power. You can get injectors from any Bosch dealer, just that you have to take the old ones in so they can cross reference the part number, they will not list Mercruiser, best bet is take them all in for a service they will tell you if the sensor one is OK or not

I'm getting quite uneasy about owning a VP D4, Great economy fuel wise compared to the previous two 5.7 litre injected petrols I had, Basically they were a USA car engine with cheap part prices. The part costs for the D4 in comparison are eye watering
 
The, Bosch system with needle lift sensor on #1 injector was a quasi electronic system only sold in small volumes and Bosch ditched it a while back, hence loony prices even from Bosch.

No clue about the rest of the engine however the D4 uses Bosch common rail system has seen prices tumbling, Bosch dealers are not even bothering to repair common rail pumps, dirt ingress can cause the little quill shaft which drives the lift pump to fail, new shaft is £250 however dealers a getting NEW CP3 pumps complete for £350 and competition has driven injectors down to £125 each.

The prices are good news as I've viewed a boat today that means a may have to move to the dark side of D6 power.
 
Well i thought i would update, tested the injector today and its working fine apparently, it was also easy to get a replacement via a normal car diesel specialist. Could pick one up for £325, which although expensive, i could live if i did have to change.

So looks like i have to shell out £400 for a Rinda tool from the states, or they do an LED dongle which will blink the codes for £150.

Does anyone know how to get the fault codes from the engine without buying an expensive tool, i have seen people doing the LED trick, by bridging connectors to dump the codes in flashes, but cant find anything on how to do it on this engine.
 
You can do the LED trick, you need to search it out on the web, the basic engine is a VM, as used in the early Jeeps and others, you will find a small plug on the electronics bow where you plug the Rinda tool in, I think this is also where you can attach an LED for a basic test. When I had my one many years ago there were 2 things that used to drop the engine to limp home mode, the MAF sensor ( on the inter cooler on the top, held with 2 cap screws I seem to remember) and the drive lube sensor. The MAF usually just needed cleaning and very carefully putting back in, and the drive lube used to sort itself out after a bit of topping up. Always had that problem after a leg service, I think it was air getting urged out of the leg.

Let us know how you get on
 
Hi John

Yes I have read that you can get the codes via an LED, problem is that this engine they use a 4 pin DIN port for the diagnostic cable, so none of the guides for bridging the diagnostic port are relevant as they use an adapter cable to go down from the usual cable to 4 pin.

It obvious it can be done as the manual even says so, but I have no idea which pins to bridge out of those 4. In fact the manual says it only uses 3 out of the 4 wires on that plug. Seems to be nothing out there at all for this engine how to do it.

Does anyone know who can help, save me spending money on a tool, I just need to know what fault codes my engine has :)
 
I may still have some info at home and will check tonight, I am sure the small 4 pin connector on the electronics box only has 3 of the pins connected, I think I may have a circuit diagram somewhere, will check out tonight
 
Mctaggart would you be kind enough to send me the details of how you can source this injector from your diesel specialist .I don't need one but as I have the same engine as you it would be good to have on record.TIA

Hi

Its basically just a Bosch injector, so you can get it in any diesel automotive specialist.

Just give them the serial number on the injector which is 0432193698

I paid £325 which was a dam site cheaper than mercruiser quoted price of £1070!

Fitting it tomorrow so will let you know if it's fixed or not.

Yes but after viewing it was a no go.
Just amazes me how owners think there boat is worth top dollar and present it in a state where you just sat on it and made a list of what was wrong with it, scruffy tatty boats don't sell, no wonder it had been for sale a year with no offers made.
 
Just to update this thread, when they say its normally the simplest of things you check first this is the case here. The reason my revs were so low was nothing to do with the injector in limp mode (even though i bought one and then they wouldnt let me return it!) so i fitted the new injector regardless.

Some clown had changed the pulse settings on the back of BOTH RPM clocks, so they were setup for an 8 cylinder engine not 6, so was the reason the revs were way off. Was SO HAPPY to find that, but also completely miffed that someone has changed them, oh well!!!
