M.V.Diveworks (10.1 meters, 4 tonnes) was fitted with a  new Yamaha ME420 sti Trp diesel sterndrive unit in December 1997. I opted for a Yamaha at this time rather than the more popular New Zealand option of a Volvo penta or Mercruiser due to Yamaha's reputation. (Unfortunately though, unlike Volvo, Yamaha offer no warranties for Commercial use)

 With trouble free operation for the first 1500 hours my first ever breakdown was due to a failed outdrive. Replacement with a new outdrive gave me an opportunity to disect and become familiar with the old drive. Since that date I have done all repairs and maintenace myself. Im often asked why I dont operate lower maintenance shaft drive or jet due to the considerable time I spend on the water but I think the advantages of being able to maintain and repair myself, plus being easily surveyable, with excellent manouverability, shallow water operation, trailerability and a minimal boat downtime by having a spare drives and engine ready to go,  outweighs most of the dissadvantages for me.
As at May  2009 and 6000 hours mostly high speed use, I have completed 4 engine rebuilds, 3 intermediate housing rebuilds and countless stern drive rebuilds for myself and others.
