Knock knock knockin' on heaven's door...


After Marelle was moved to Premier Swanwick Marina, we needed to charge up her batteries (and hope that they held their charge after having gone flat while she was on the mid-river mooring at Deacons). Martin spoke to Barden UK and they recommended the CTEK MXS10 8 stage charger. We connected the charger up, and were relieved to see that on both batteries it passed the stage that tests to see if the battery could hold a charge, and left each one on charge overnight.

Now the moment of truth, will the engine start. We dutifully followed the cold start procedure – Marelle has a Volvo Penta 2003 fitted, and has had numerous starting problems over the years according to the paperwork and bills we got with the boat. This involves putting the throttle in neutral and furthest forward, then operating the stop handle 5 or 6 times. A silent prayer, and then – click. Nothing else. Batteries read 12.8V, but no sign of the starter even trying to turn. We took the engine cover off, and peered at the engine while trying again. The click was definitely coming from the engine area, but still only a single click each time the ignition button was pressed. Same result with both batteries linked up to the ignition circuit.

Ben had left on board a boat manual he had made up, a mixture of excerpts from magazines and hand-written instructions. Looking in this, at the engine trouble section, the advice was that the solenoid could be the problem, and to check this by shorting it (connecting a screwdriver across the ports). This carried a warning that sparks might be generated(!) but unfortunately no hint as to the location of the solenoid or information or detail of how to do it. Martin phoned our friend Roy who has a motorboat, and he had the same advice, but we didn't try it as we still weren't sure exactly what to connect.

Dejected, we went home, and I spent some time trawling through internet forums to see if I could find any hints or tips, while Martin phoned round a few Volvo marine engineers.

Sometimes the power of the internet is truly brilliant.

In amongst all the shorting advice, and scary prices for starter motors, was a genius tip that the first thing you should try is hitting the solenoid with a hammer. To be honest, I thought it was bizarre advice and only read it out to Martin because I thought it was funny. We found some pictures of how to connect to the ports on the solenoid, charged up our portable battery jumpstarter (less worrying to use than holding a metal screwdriver!) and the next day Martin went back to the boat to try again.

He tapped the solenoid, lightly, a few times. Then tried the engine, and it started straight away!!! He hadn't even followed the cold start procedure, yet he said it started really well, better than it ever has! Maybe some of the previous starting problems were down to less than optimal batteries.

Just to be sure, Martin has started the engine a few times since, and had no more trouble. We were amazed that it worked, but quite relieved too – and it just goes to show that you can find some superb advice buried on internet forums.
