"Hey everyone,

I was just given a boat and motor ....90 hp johnson model number 7988787.

I am not sure what year this is but in the 80's I'm sure.

I would like to remove the injection from it and just run it as pre-mix. Can anyone give me a step by step in doing this please?

Thanks"
 
So I found the vro removal ins

So I found the vro removal instructions and followed them.

I plugged the oil line just outside of the lowe cowling just to make it easier on myslef is this OK?

A friend came over ( a boat mechanic) and said that I had to "loop" the oil and fuel lines on these ? Is this true?

Thanks
 
Must of been a Merc mechanic -

Must of been a Merc mechanic - you loop the oil line on certain mercs which saves you removing the oil pump and paying merc for a plate to cover the hole if the pump is removed..
