Prestige 32 - Fuel Tank query

[Timmy92]

I have one fuel tank using more fuel than the other & wondering what the issue could be?
Both Valves under the rear seating outside are "pointing vertical"

All information greatly appreciated

Hi they aren't valves they are pull stops for the fuel shut off.

Theres no balance pipes on a 32 between the tanks so one engine must be using more!

Are you on the TAMD or D4 engines?

It's a 2001 boat with KAD300 engines.

It's quite possible then you have slightly more load on one engine which explains the difference

EVC 1?

 

[Timmy92]

Yes - I believe so. We've only had the boat a few months so .. Trying to grasp the essentials.

 

[Timmy92]

Silly question maybe but what do you mean by "load"

Are you running a genset or heating? Just a thought.

Have an Eberspacher heating system but rarely use it.

One engine is working harder than the other and thus consumes more fuel. Don't remember how but I think you can sync the rpm's on these engines which might help. If the rpm's differ between the engines while cruising the one with the highest rpm will be working harder and consume more fuel.

Thanks for the info guys - the EVC controls have an equal sign so the revs can stay the same i'll try that & see how it goes.

I have the same EVC1 and Kad300 on a 2003 P32.Yes that equals sign will sync above a certain rpm, not very low speeds; then only use one throttle control to control power to both engines.It will drop out at lower revs. I am just getting Yacht Devices engine gateway to N2K to display engine data on my Raymarine MFD Axiom9. Then I can monitor fuel flow and also temp on flybridge. See https://www.amazon.co.uk/dp/B07GNL1WPZ/ref=pe_27063361_485629781_TE_item
Two versions for N2K or Raymarine style N2K plugs. In EVC1 engines it connects to the white 2 wire connector on top of the engine block, inside the relay box, then to your N2K. Set up can be made for 2 engines and 2 tanks.
