Lots of people say the the DV10 are underpowered, I do not think so.
it comes down to a worn
engine.mine is being totally rebuilt after 45 years as it started to get sluggish but still did the job.
There is no way a yacht manufacturer would put an underpowered engine in their vessel and then go on to sell over 400 of them (
compass 29)
Such a great simple engine.
