Hello everyone, we are new to this forum and are hoping that someone out there with knowledge of Lister engines will be able to assist us. We have a Twin cylinder air cooled diesel 17.5HP engine in our 50 foot narrowboat, which I am told it is an ST2? At one time, in the engine compartment it had some sort of canvas tube attached to a frame which linked the air intakes to the engine to assist in cooling it. This frame isn't there any more and so the engine runs hot all the time. We have taken to lifting the engine cover to allow more air in whilst we are travelling but this is far from ideal due to the smoke and noise from the engine. The engine runs ok but does tend to cut out at really unfortunate times, like as you enter locks etc. we are told this is because of her running hot? Anyone out there with a knowledge of this air cooling system that could point us in the direction of plans, photo's of someone who could help us make one?
In addition, I'm told my prop isn't suitable and is a sea going prop with much smaller blades than a still water prop? Is there a prop that matches my engine? Someone mentioned a company called Crowthers, anyone know them and what they do?
Thank you.
Pete
