Well that took way too long to sort out.
From what looked to be a small fault, it proved to be a much larger and more expensive one.
Initially the engine would not start, I checked some connectors and it started.
Tested it several times and went to an anchorage in the harbour, went swimming and cleaned the hull and sterndrive.
A few days later went onboard to give the clean boat a test run, as on the previous fishing trip it seemed to have lost speed compared to the engine RPM. When I got onboard the engine failed to start.
Fiddled with all of the same connections again, but this time it would not start. read out said , engine in gear will not start.
Initially I kept checking things online and Chat GBT which gave a variety of possible causes.
I made a list of them and over a few days in really hot weather, worked through the list.
No change
I was being helped by Richard from Pinnicle Marine, but eventually we ran out of things to try. I had to book another engineer to bring his Volvo Vodia diagnostic system onboard to fault find my Volvo Penta D4.
[Richard did spot a cracked bracket on one of the pump mounts, I ordered parts and fitted while waiting for parts to arrive.]
This system indicated that one of the EVC units was showing fault, not only would I need to buy a replacement PCU, but then I would have to have it programmed to communicate with the other parts of the system by Volvo.
This part is not refundable due to programming, we were only 99% sure Vodia had this right, but it had to be changed.
To be honest the engineer was as worried about this as I was, so with permission of another boat owner at the yacht Club, he fitted my PCU to another vessel and its system immediately came up with the same fault code.
This is where time started go wrong.
The engineer went on holiday.
Volvo Penta messed up the order.
Engineer returns to be told part not ordered. But worse than that Volvo Europe were now on shut down.
Part arrived back in UK about a week earlier than anticipated after programming. engineer fitted it and all system start communicating with each other, great news, but engine would not start [*^*^*^] A bit more auto configuration and calibration bought up the same message that we started with, "engine in gear will not start."
During the initial fault finding Richard and I had tested the throttle lever, to find that its microswitch closes a circuit when in Neutral. I had made up a small lead to insert in the circuit to trick the system. It had not helped at the start , but was still onboard, so we used it again.
I was very pleased when Sam turned the key and the engine started for the first time in over a month.
Three faults all at the same time. who would believe it
When I get back to the office, I contacted Volvo to just pay them for fast delivery of a part. Once again they were useless [Its obsolete, no alternative]
Back to the boat to get the control lever, then a few hours trying to chase up the part required. I could not find the complete part ,but did source two options for microswitches, sod it I ordered one of each.
After a few more days parts arrived and one of them was a good match, so was fitted.
I took the lever back onboard, wired it up and all was good again, engine runs, gear change works.
I only had time to properly fit the various parts back on the boat and engine, before Wendy and I flew off to the sunshine of Madeira for a week, [The holiday was cheaper than the parts]
When we came back, I still had the original fault to sort out. That of slow boat speed for engine RPM.
After getting hold of, and cleaning up a second hand set of G5 props, I changed them from my dinghy last Friday.
Out past the chain ferry, throttle up and back to the usual boat speed at 2500RPM. At last I have my boat back.
Sorry for the long ramble, but I wanted to give other Members an idea of what I have learned from this experience, apart from how frustration it is to have a broken boat in a long hot summer.
1. If you fiddle with what may be loose connections, do it one at a time, so you know which one fixes the issue, should the fault return.
2. Volvo Penta parts departments are useless, chase them up for spares and ask for confirmation of orders
3. Volvo parts are expensive and not always available.
4. Find yourself a good engineer with knowledge and contacts for your boats engine.
5. Have a very understanding wife.
Lastly have some very good friends at your fishing Club, that will listen to you banging on about bloody boats, engines and particularly Volvo F*****G Penta. But offer you the use of their boats or take you out fishing.
Thanks guys, you have helped keep me sane since July.
I hope that the fish are biting now Alfresco is up and running.
