Hi all, I have a Volvo MD7A in my Sabre 28 that is giving some grief. For the last year it has been blowing white smoke out the exhaust which indicated to me water in the fuel. However, after running it with clean diesel on an external tank the problem persisted - not good.
Now I have a cooling problem so I can't even move the boat. I changed the pump, impellar, thermostat, cleaned out all the lines (found some old impellar pieces) but it still will not pump water. I checked to see how fast the impellar was spinning and it was not very fast (only my opinion could be wrong).
Looking for some guidance, maybe time for a new motor or rebuild?
