My 2016 505 #123 experienced an MDI failure offshore last week. Engine shutting down intermittently. Hour meter stopped working. We eventually disconnected the shut off solenoid, and aside from the alarm which went off every time the MDI tried to shut down the engine, it was an effective work around. 550 hours on the engine. Will install an emergency start button. I don’t trust these MDIs.

Hi Rod
I have only just seen your message, we installed he emergency start button ourselves as per Roger's suggestion, the only tweak being that I installed it low down in the second cabin so that the engine can be started without taking off the side panel to the engine 'room'. The other thing to remember is that the MDI controls the engine room fan, so we have installed a second switched power supply directly to the fan.

Hi Paul
Can I ask the purpose of the extra switch for the engine room fan? Is it so that the fan can still be switched on even if the MDI fails? If so, I think that is a 'nice to have' rather than an essential safety feature (which I consider the start button to be). I ran High Time for 4 years without the engine room fan working. The fuse for it (the 10A one on the top right hand side of the main distribution/fuse panel) was missing from first commissioning and I didn't realise until I started investigating my MDI problem 18 months ago. My previous boat, with a 50hp engine never had an engine room fan and operated for 15 years without problem. I think it is a recent Recreational Craft Directive requirement but I'm not really sure what function it is suppose to provide.

Hi Roger, we currently have two broken MDI units both of which are less than a year old and being stubborn I refuse to pay for another one, so until Volvo replace these under warranty we are using the 'emergency' start button in normal use and felt it better to be able to switch on the fan as well, especially as we are in the tropics.

Hi Paul
Understood, thanks. I guess the blower makes sense in the tropics and similarly the separate switch if you are permanently without the MDI.

My understanding was that replacement MDI’s with a “P” in the serial number have been engineered to address this issue. This per Superior Deisel in Charleston SC.
Anyone have an MDI failure with one of these “P” identified units? |

Thanks for the info Kipwrite. I am going to call the Volvo centre tomorrow so I will ask if they are aware of that. I’ll let you all know.

Here’s my replacement MDI with the “P” designation. So far so good.
