based upon my experience,which is pretty vast.... stern drives - they get a bad rap from owners who do not believe in upkeep/maintenance.drives need to be pulled yearly - lots of people skip this,which leads to problems. bellows require replacement,5yrs is normal,exhaust systems - these require replacement as well,5 yrs is the norm. starters,oil pans,gimbal bearings - these failures are caused,not happened.water in bellows,from leaking bellows that should've been replaced years ago,this ruins gimbal bearings,u joints and input shaft seals/shafts,and it brings water into the boat,via the "weep hole",which causes excessive water in the bilge - due to most owners not having a back up auto pump,under the motor,as far aft as possible,this keeps water off everything,avoiding water intrusion into the flywheel housing,causing starter failure...it's called "preventative maintenance",a very important thing...see how one thing leads to another ?? one of the biggest old wives tale is the - if the bellow leaks,the boat sinks - not true input shafts are "o" ringed around the gimbal bearing - it's sealed - water will trickle out the weep hole.shift cable bellows - these will trickle as well.the boat sinks due to the bilge cycling,and running the battery down - boats docked with shore power,most people will never know there's a problem,with out inspecting... I had over 20 customers with stern drives - Volvos and mercs - never did ANY of my customers have problems like that - reason being,"preventative maintenance" in 20 + years,NEVER had to pull a motor,to replace a starter there is no answer to what's better - outboard or stern drive,it's what works for you
