Engines in the first generation of Trintella yachts have often been hard at work for many years, which gives rise to the question if the diesel engine should be replaced or overhauled. After a short introduction discussing the causes of procedures, this TIB delves into the considerations. Attached are stories of four Trintella la and lll owners who share their experience in this process. An English translation is in progress. Please use Google translate for this Dutch version.
