I have 2 suzuki 6hp 4 strokes both now 18 months old, 1 has 1 hr on it and is long shaft (used as reserve on boat) but never actually used in anger so need to finish run in etc. manuals and tools unmarked and in bag
also a standard shaft suzuki 6hp used for 3 hours as tender engine never pushed and ditto manuals and run in etc.
