How To Service your engine in 12 simple steps

Ali Wood gets some expert advice from Stu and Laura Davies on Maximus’s engine, fuel system and Volvo Penta saildrive

As Andrew Simpson says in the RYA Diesel Engine Handbook, ‘A wise skipper will maintain their engine properly and know exactly where to turn if it develops problems’. Knowing how to diagnose and fix faults is a useful skill for any boat owner, but of course, prevention is even better.

Now that Maximus’s hull was painted, topsides polished and seacocks replaced, our Maxi 84 was looking good. The mast was wired, leaks fixed and thru-hulls fitted. It was nearly time for launch… but the one job left was giving me sleepless nights.

For two years, the 43-year-old cruiser had been languishing in a Chichester boatyard and it was anyone’s guess what shape the engine was in.

There was, however, a glimmer of hope. The day following the survey we’d asked Dell Quay Marine to jump-start the engine (the batteries having been flat when we viewed her). It started first time. Also, the previous owner, Daniel Kirtley, who kindly donated the boat, had been meticulous with servicing. Any faults with the engine wouldn’t be through neglect, but just time spent inactive during lockdown.

I called PBO’s engine expert, Stu Davies, and asked him if he wanted to do the service. He didn’t hesitate, and drove five hours from North Wales with his wife, Laura. By the time we’d finished, Maximus’s Volvo Penta MD2020 engine was in tip top condition. I never realised engine servicing could be so much fun!
