water cooled fitted in a Bateman RB25. Is there anything to watch out for in high houred models? I’ve been offered a very tidy RB25 but it’s done 12,000 hours. Two owners and I’d be buying it privately so no come back. In general it’s extremely tidy machine and I’m not to bothered if I need to replace the pump or spray lines but replacing an engine is a different matter. Realistically how long can this engine go for? Asking price is £20,000.
