Any common problems ?
Only 3 hours on it

Only recurring problem I have seen on these engines is the small pressure pipe from the inlet manfold to wastegate fractures, easy to replace.

If its stood for 20 yrs then I’d check all perishables like hoses, belts, exhaust rubber on exhaust. If its a stern drive then replace drive shaft and gear cable bellows and exhaust bellows as these will have hardened and will split. Also empty fuel system and fill with fresh and replace coolant.

Check the front pully see if it is loose, they had a habit of loosening.

Under load or in neutral?

Is the turbo spinning, easy to check with the engine off by removing the air filter..

Turbo is stuck !!! Where will I get 1 ?

Its probably rust on the exhaust side, if you take off the exhaust bend which you will have to anyway you might be able to carefully scrape away the rust from the housing where its jamming the exhaust turbine, its worth a shot before buying a bew turbo.
