A Leaky KM2P Gearbox And A Yanmar 3YM20 Engine Losing Coolant

Double bubble visit to Kent, for Ross this week.

His first visit, was to a Jeanneau Sun Odyssey 349 with a leaky KM2P-1 gearbox on it’s Yanmar 2YM15 engine.

He removed the gearbox, changing the output seal, Ross also pressure and vacuum tested the gearbox before reinstalling it.

He then trundled off in his van, and travelled to the opposite end of Kent for job number two.

This time he was attending to a Hallberg Rassy 310, with a Yanmar 3YM20 engine.

The customer reported loss of coolant, and was keen to isolate the engine cooling system from the calorifier, to help track down the leak. Ross suggested that he fit one of our calorifier kits, which include handy isolation valves.The customer was over the moon with his suggestion and the kit was fitted successfully. Ross left him to carefully monitor the coolant levels.
