Good work. Note that the ignition barrels will fail soon if they're the originals (I've had to replace both of mine on my 2003 T34). Allow £250 per side!

I plan on replaced this soon as it feels terrible, did the port last year so was in my “to do” list

Hi All, I have an update. Over the weekend I replaced both port and Starboard Pots. Not too challenging. Recalibrated and so far the system is behaving as expected so fingers crossed! As promised the pot replacement method: -
1, Label up control pot starboard front and back to be sure it all plugs in the same way it was.
2, remove control from helm mount
3, disconnect port and starboard pot plugs, (label port and starboard)
4, remove micro switch brackets (not used on outdrive model)
Unscrew 2 x 8mm nuts from screws holding pots in
5, remove starboard pot first, be carful to maintain gear cam relationship.
6, remove screws from port pot and housing. This is a tease as you need the hold the screws up and thread out. They will come out but be carful,
7, remove port pot. Again be carful to maintain gear cam relationship.
8, the old pots will have a dust boot on them, you will need to take these of and put them on the news pots.
9, place new port pot on “D” lug on the gear cam, hold in place while threading the 2x screws back in housing.
10, place Starboard pot on as port pot.
11, refit 2x 8mm nuts and nip tight.
12, refit micro switches
13, refit cables and replace control
14, calibrate both port and starboard throttles!
Hope this help!

Peter, thanks for coming back and this. As you say, hopefully it will solve your issue.

Hi All, just on the boat. Running both engines, thankfully no gear change problems. However, when I put the port engine (the same engine I had the gear Change problem ) In to forward gear the Revs pick up to 1000rpm. The only difference from when this worked fine before is I turned off the battery switches before leaving the boat. I have recalibrate the throttle and it is now working perfectly. Can turning the battery switch off cause the ECU to loose memory? What else could cause this? Thank you

On a 44 yes as it has a separate feed from the battery to the ecu .

Paul, I don't understand your reply. Surely
Isn't Peter asking if the ECU loses it's setting when he switches off his battery master switch? That can't be right as it means that he'd have to re-calibrate his throttles every time he uses his boat (unless he keeps the batteries on permanently).

calibration is not too much of a task, I would rather do this every time I visit, as I would prefer to turn off my batteries. Is this right?

It's not right. I turn my batteries off every time I leave my boat and I don't need to recalibrate.

Yes you are right, is it likely that the old drifting pot issue has returned?
I think I will fit the SPM module Paul mentioned. Is this an easy job?

VolvoPaul has fitted loads so he'll know how easy it is.
I believe the hard part is finding the two spare connectors that you can see in this diagram...
Volvo Penta Exploded view / schematic Control System for Twin Engines and Single Station.: B KAD44P-C, KAMD44P-C, KAD300-A, KAMD300-A - MarinePartsEurope.com
Somebody on a T34 or T37 (I can't remember which) recently said they were hiding above the ceiling in the aft cabin!
Could revving to 1000 revs be a different issue (stiff or poorly adjusted cable / worn clutch / contaminated gear oil)?

Thanks Pete
I have seen a picture online of the SPM, am I right in saying it connects between the Pot plug and the socket into the loom?
Do I need 2 SPMs one for port and one for starboard?
As you say finding this may be tricky but there’s quite a lot access points and space on the T37. Thanks again

I've never fitted one myself so all I can repeat is what I've read elsewhere.
Your understanding of how it connects is correct.
You only need one unit for two engines.

Sorry I missed replying to your last point. I don’t thinks so, problem was solved as soon as I calibrated. I fitted new cables last year, changed oil in leg and check oil for contamination, all clear.

Brilliant looks like I’m on the hunt for a SPM this winter. Thanks Pete

You can get them from Volvo or Coastal Rides often have a used one.

Hi guys, I am trying to see if my local Volvo dealerships will supply the SPM module we have been discussing to stop the Rev drift. Is there a reference number for this as the dealership dose not recognise the modified for the Kadf44s ?
volvopaul

The SPM doesn’t stop rev drift as you describe it, it stop the edc selecting gears .
Peterclayton68

Oh my misunderstanding, what could cause the Rev drift?
It clears when I calibrate but returns a couple of days later. It also does the same when I press the neutral button too with no gear engaged.
