i have a 1972 9.8 hp merc. serial # 3267352. my question is this. my carb is seaping fuel. i'm sure the gaskets are all original and need to be replaced. my local boat shop seems pretty crappy seeing how i've taken it there for other issues before and they never fail to mess something up. so, is rebuilding a carb something that the average joe could handle? i've worked on cars quite a bit, but never on a boat motor. i was thinking of getting a repair manual and a gaskit kit and trying this one myself, but thought i'd get some opinions first. also, which repair manuals are best? thanks.
