"Berwick’s guide is a huge asset for those wishing to get a little more hands on in the engine room due to its simple, visual directions...it is essential material for anybody just starting out on diesel engines due to its clear illustrations. It would have saved me hundreds of hours of researching and watching long-winded YouTube videos when I began tackling our own power plant. Even after 5 years of full-time cruising and engine maintenance I discovered a number of new tips and tricks in this guide. I highly recommend it."
"Mwongozo wa Berwick ni rasilimali kubwa kwa wale wanaotaka kupata mkono zaidi katika chumba cha injini kutokana na maelekezo yake rahisi, ya kuona ... ni nyenzo muhimu kwa mtu yeyote anayeanza kutumia injini za dizeli kutokana na vielelezo vyake wazi. ingeniokoa mamia ya saa za kutafiti na kutazama video za YouTube za muda mrefu nilipoanza kushughulikia mtambo wetu wa kuzalisha umeme.Hata baada ya miaka 5 ya kusafiri kwa muda wote na matengenezo ya injini niligundua idadi ya vidokezo na mbinu mpya katika mwongozo huu. Ninaipendekeza sana."
