Spring recommissioning

Recommissioning your motor boat in spring for the coming season should be straightforward if you’ve winterised it properly

Here’s a useful checklist for two key areas:


  • Reconnect the fresh water pipes in the bilge
  • Reconnect the pipes to pumps and calorifier
  • Fill the fresh water tanks and check for leaks
  • Connect the fresh water plumbing systems and check the flow of water to all outlets, then check the toilets work

  • Unseal and reconnect the exhaust system
  • Unseal the air inlet and refit the air filter
  • Fit a fresh seawater impellor and gasket
  • Reconnect all sea water hoses
  • Check the engine and gearbox oil level
  • Check the antifreeze level and strength
  • Check the stern gland and vent
  • Open the raw water inlet seacock and check for leaks
  • Test run the engine while alongside and check instrument readings
  • Check throttle and gear controls then shut down the engine

Top tips:

  • Give everywhere a good clean – this allows for better visual inspections and potential issues can be resolved before escalating
  • When winterising, make a check list of every step taken, then when the time comes to recommission, work your way back through the list to ensure you haven’t missed anything
  • Don’t forget your tender’s outboard. Get an engineer to service this to ensure it starts when you need it to
