Slightly off topic but I thaught people with aluminium based engine block experience might have an answer to this:
20 ish year old 2 hp Suzuki not much used outboard engine still works well but is overheating enough to start to sieze after a few minutes, apart from checking the impeller, I think it has been left long periods without being washed through with freshwater prior. Is there a liquid mix I can run through the waterways (preferably running the engine in a tub of the mix - which might defurr the waterways without pulling the engine apart? This probably wouldnt' be worth the trouble as the spares could be difficult, breaking studs etc. in this old engine which has never been stripped. Charlie+- posted
