Volvo D6-330 Boost Pressure Sensor - where is it?

[SC35]

Boat next door has issues with one engine low rpm.
D6-330’s.

Where exactly is the boost pressure sensor on these?
Diagrams are hopeless.
Actual photo much appreciated.
Part No 9, I think.

Part nr 9. Remove the black top cover and you will see it about halfway back to one side on the inlet manifold.

Do you have a picture?

Mechanic swapped over the sensors - the problem didn’t follow the sensor :-(

Don’t buy them from Volvo.
Go to a good motor factor like Euro Car Parts. They are a standard Bosch sensor at a third of Volvo prices.
Mine seem to fail every 5/6 years. D6 350hp.

What’s the engine speed for the other engine?

We did think that, but it has the newer SS props and it can plane - 22kts or so with the other engine not getting past 2600rpm. Normal top speed would be 35kts+
When I had a slipping prop, it was 12kts and a funny smell.
Fuel filters were checked and replaced. Very small amount of black stuff found, but nothing abnormal.
Current plan is that they will limp back to home port at displacement speed and get Vodia hooked up for a proper diagnosis.

The limit of 2600 sounds like a seized or damaged turbo as it's nearly out the range of the super charger .

Mechanic (not a Volvo specialist) did say something about duff turbo. But the strange thing was, all was working fine until they pulled back to idle for a break. Then this …

It’s a D6-330, I didn’t see a supercharger on it.
