I was thinking the same about the mower box. Would I open it open it or not? Would I try to open it from underneath so it still looks unmolestered? I reckon that outboard looks rebuildable if you were up for it, It'd probably be easier and more fun to splice another powerhead onto it though. A bloke at work was telling me about some nut jobs on a BMX forum getting all excited over bikes like you just scored and they were selling (yes some nut job handing over hard earned cash) tuffs for $1000. You never know, one might have grandads first model Pace he wants to off load on a deal for "some really cool bike parts"
