Evinrude Rebuild

I have an Evinrude 1988 88hp spl.  Itís on an 88 Sunbird the motor would jump when we would run in forward at any pace we checked timing ..OK so we thought prop..got rebuilt.. still prob. so must be lower end. Yup I am planning on rebuilding it cause the clutch dog and forward gear are slipping you said that it would cost more to rebuild than to get a rebuilt on from that certain place you had recommended in another answer. I found everything to rebuild it for around 300-400 do they sell the rebuilt one for less than that? 

Also one cylinder was not igniting and had silver dust from the head and piston collecting on the spark plug Iíve cleaned the carbs to make sure it's getting fuel but the paint was bubbled so we knew it had been overheated before I got it. The cylinder wall also has some light scratches and piston has rounded off some compared to the others which have sharp edges on the raised part. Would you go ahead and bore out all four and put new pistons and rings in or if it isn't to bad just hone out the scratches and get one new piston and rings? I will be doing everything w/ a friend who works as a mechanic for a boat shop around me so labor will be nil. Wondering what I should expect to pay for piston / s and rings? 

Thanks for your time

Bob, 

    Sounds like you have a real can of worms. Definitely rebuild all the cylinders with fresh pistons, rings & bearings. New pistons and rings are usually less than $125 each. The gearcase parts are reasonable and a rebuilt case will run over $900. Take your time and inspect all the parts and replace worn items. Now is the time as it is easier to replace when apart than later. Break it in nice and you should have a good rig.
