Has it a sail drive or gear box and prop shaft looks like a straight motor and gear box which is better In my thinking
Bukh 36 should be ok
On the back of the head there's a replaceable anode which should be changed regularly that's on the DV 20 and DV24 I'm not sure where the DV36 anode is fitted but it will be in the manual. If its been serviced regularly should be OK maybe a top end over haul at some stage just to freshen it up

While on the subject has anyone repowered their boat recently and give me some idea of what it has cost. Older Volvo Penta diesels can be repowered with a later mode with a kit so I am planning to do that. But getting anyone to give me a price has proved fruitless. Forums on the topic generally just return waffle with no-one saying it has cost me $x. So has anyone actually repowered a boat and what did it cost?

Hi Karmarules,

regarding the Bukh, the service history will be the most important factor, it should be OK if servicing has been correctly carried out.

I have owned a 89 Cavalier for around 5 years. I love the boat. I sail mostly with two on the boat, used for anything from day sails to a couple of weeks away. The rig is fairly simple, but she still has a reasonable level of performance. Onthe other hand, if the family want to head out for a day sail the cockpit fits 6 adults And a couple of kids in comfort.

The hull is solid glass. Mine has needed treatment for osmosis, but that is not unusual fora boat of this age. repair cost woukd depend on extent and how the repair is carried out.

The real concern as boats age is not the hull, but the bits that are bolted to the hull, engine, rig, anything electrical etc. If you do not feel competent to assess then get a survey. For any boat this age talk to the surveyor about osmosis, and how they will check for that. After my experience. I would insist on moisture testing for any boat of that age.

My boat is on Lake Macquarie if you would like a look, and a run through on what I would look at.

My boat was repowered with a Volvo md7b the week before I bought it. Fully reconditioned unit, better than new real marine Volvo. $2250. They used to be advertised in the back of the "Afloat" magazine. Smooth and quiet, should last 20 to 30 years will average abuse.
