The internet is full of negative reviews and issues with the EDC on these Volvo engines! Never had Volvos before and have a few questions. I'm considering purchasing a boat with twin TAMD75 with 550hrs. Upon the last ride of the season the following occurred as described by the owner which I will paste below. The boat is discounted heavily and even if this repair was 15K I'd still be ahead of the game. But, should I be nervous of Volvo engines and search for a boat with different engines? Here are his comments and so far he has been very forthcoming with any issues with the boat, etc.

A few weeks ago I took the boat out and the starboard EDC (Volvo’s electronic transmission control) started to act up. Boat ran up to almost on plane, then went into neutral. Turned around and went back in. Starboard forward was disengaged. I only had reverse. This may be anything from a loose connection to possible needing a trans overhaul. I am almost certain it’s something electronic. I’ve dropped the prices considerably to move the boat on.

Thanks for the advice everyone.
 
Could be so many things,

but since it just the one direction can’t be a loss of clutch pressure.

could be the control leaver itself... if there a second station has this been tried??

The gear is actuated by an electro magnet these can fail, and are cheap to replace. I’d swap them over forward to reverse and see if the problem travels.

tamd75 is a fine engine btw
 
If it was running fine before and this is a new thing.....I’d say buy it.....£15k is a lot of budget to spend on Volvopaul to probably have it fixed in an afternoon ?

you can put them into forward manually at the gearbox - this will tell you if its mechanical failure. Get the manual. Swap actuators to see if the fault swaps sides. Loose connections or actuators my guess. You'd get 2 replacement gearboxes for not much over £15k.
Volvo no worse than the others and has the advantage of ubiquity - like buying a Ford back in the day.
 
The snag is that should it be an ECU fault ( and given the owner has decided not to mind it this is possible) as you will see form the other running thread there are no ECU available from Volvo.

Before committing I would employ someone to truly find out the problem and also discuss with the vendors engineer.

Normally money will solve a problem, but if it is the ECU then currently this is not the case.

Sounds like it’s gone into limp mode , fast idle still in gear to get you home .

Now if owner or skipper not clued up on edc and just returned to base you all know nothing about the fault .
Best course of action is to plug diagnostic key in and read the stored faults even if placing the key in stop position has erased the fault code in question . So did the skipper act with the correct protocol or just panic and give up ?
Problem could be anything from bad fuel supply to rope around prop , over boost due to sticking wastegate , all this can happen especially of late as so many boats sat idle doing nothing .

Is it UK based , what model of boat etc etc .
Give us more info . Back in due course .

Dont suppose it’s Phantom 46 by any chance .
 
Boat is in NJ, USA. Spoke to local Volvo place and they kind of said the same things as the various forums. Could be about 10 different things with the most catastrophic being a ECM failure needing replacement with a guesstimate of the part being about $7500. He was also aware of the backorder issue during the summer and is not sure if it has been resolved.

So best case is it's something relatively easy, corrosion, connection, etc., with worst being a needed ECM replacement which is not available. Nothing worse than buying a boat for the family to use and have it inoperable due to a part that is not available. I'd feel like an idiot, wife would kill me and kids would be disappointed. LOL

Price is extremely attractive and the boat is nice which is why this is so tempting. Going to look at the boat in person on Saturday.

Volvo service place recommended unwinterizing the engines, putting boat in the water and giving them a few hours to check it out. Seems reasonable to me but have to see if the seller would agree. My gut is if the boat goes in the water and the issue is simple and inexpensive to fix he will want more money for the boat....
 
Just found out a few more details....

Ran the serial numbers and found the 06/04 TAMD74/75 gear shift (including: 4380-2125,-2132, 4877-1676) recall/service was not performed.

Could this be the resolution for the issue??
 
If you was the seller , you would have volvo engineer fix problem say exsteem $5000 , boat fine sell it to you for 15 k extra . No one can give that money away.

I completely agree, unless he has fallen on unforeseen hardships, etc. I know he bought the boat in 2017 for 99k and started this process in October asking 125, then 119 and now is at 109. Probably bought the boat and is looking to use it with no real expenses and now looking to sell. Can't blame him for his philosophy as I have done the same many times over with boats. Just need to make sure I'm not buying a total lemon and headache.

Well surely if he paid 99k 3 years ago , and i take it was running fine then now i would want to a lot less than 99k . The maths dont add up. ps where in the states are you based.
 
Boat is located in New Jersey.
Seller is also completely unaware that I did some extensive research to find the boat listing prior to his purchase. All he knows is I am interested in his boat which was advertised at 119k and now at $109,000. NADA/BUC value for this is 140k and he is asking 109k with this known shifting issue.

Definitely a gamble on my end but so far it seems like the fix is relative easy and inexpensive with a qualified Volvo tech familiar with the recall and proper troubleshooting know how.

in 2017 prior they did about $9000 worth of work, new belts, exhaust elbows, oil changes, removed and cleaned heat exchangers, etc.
 
He has not got the liquidity to get it fixed .
What else has been skipped ?
Find another because there no guarantee within a short while of your ownership that a elusive ECU will be needed and your summer is spent sat on a static floating caravan .
In the states aren’t CAT , Cummins and DD s part of motor boaters DNA ? Every part on almost every street corner for a few cents :)

I know and agree but if a boat worth 155k can be had for 100-109 and it needs 5k in repairs it could be a good purchase. The comparable ones for sale online are asking 150-169k.

This is probably a boat we would use for 2-3 years and put about 30-70hrs on each year.

If it starts and runs the ecu is fine , my hunch is overboost , there was also a wiring loom modification in early years that are now corroding away due to poor joints , this causes limp mode to happen. As I said we need to see the codes .
I know of some used 74 edc ECU , they are out there .

I feel good that both engines start up and run fine (according to the owner) but the issue arose when trying to get up on plane.

Called the marina today and the boat is blocked in and probably cant get it in the water till mid March. That doesnt help!
