cruising speed beneteau 40
Hi I am going to buy a Beneteau 40 from 1996 with a Yanmar engine.
The boat has been in the water for more then a year.It has a lot of Barnacles
also on the prop.While sailing it got to 3000 rpm and a speed of 5.5 knots to 6 knots.
What should be my maximum speed and my cruising speed?
Should a 12 year old engine perform like a new one and what is the life expectancy of this sort of engine?
All advice is appreciated.
