What's in a good tune-up?

I have a mid-80s vintage 70 VRO which has been pretty low maintenance in the 6 years I have owned it. I change the lower unit lube and fog the engine every year before putting it away but have not done anything else.

This year I started to encounter some problems and have put a new set of plugs in but that is it. I think it may need a carb rebuild.

My question is this: if I took this motor to a reputable marine mechanic and asked for a 'tune-up' or 'regular maintenance', what should I get for that? I think a carb rebuild may be in order, and I am tempted to try that myself but I don't know what else should be done on a regular basis (a related question is how often should the carbs need rebuilding...I know this one was done just before I got it). I'm not sure I would want to mess with any of the ignition stuff.

Re: What's in a good tune-up?

I would recommend:


-compression test
-inspect water pump, regrease driveshaft splines
-check alarm operation
-decarbonize
-carb rebuild and fuel filter change
-link'n sync
-check for fuel/oil/VRO leaks and replace fuel lines if not done before....
-proper spark plugs
-inspect and service thermostat
-check leg oil for water and metal flakes
-visual check on prop shaft for bends
-regrease prop shaft splines and all zerks
-clear drain holes in leg
-inspect zinc's
-test and service charging system and battery

Other may add :)

I going with, it falls under tune-up....
What im wondering is how many outboards have Power Steering?

I can't see how it falls under tune-up, because tune-up falls under "as needed".

That would mean you don't check your water pump until you have performance issues "as needed" ?
