The high rate of shop labor cost makes these things a replacement item.----But if you have the tools and search for repair kits it can be done I think.
The price of a new factory VRO is scary.-----A convention pump is an easy decision for me.----Instead of near $1000 ca for a new VRO pump , I repair the old style pump with a new $10 diaphragm.
Where is " up here " ?-----I have used a milling machine with boring head to do these motors.-----Friend ( now deceased ) let me use his equipment.----Cost me $25 / hole.----Carefully honed cylinders at home myself.----Done many of them.
Good used outboards with warranty are few and far between.-----Many 2 strokes are ruined by folks who do not know how they work.-----Folks invent new ways to destroy them on a regular basis.-----Learn to rebuild it properly and you will have affordable boating for a long time.
These are excellent motors..-----Rebuild it with 3 new pistons in there.-----But you must determine the cause of the damage.----Run it for another 20 years.
