engine rebuild???

[REEL-BREAK]

What are some of the areas of concern when doing a rebuild? This guy said if only 1 cylinder needs a piston put only 1 or if 1 needs bore .020 do the 1 is this right.Id think doem all bearings to but Seems as more poeple I speek to this is not the case with outboards.Hey Ive got a 130 yamaha Im wanting to rebuild could this be a do it yourself project given mech.inclined and using manual or no way. My engine has low compression on 2 cyl.If bearings check out and cylinder not wore would it be possible to only do rings. Give me 02 worth Thanks

Re: engine rebuild???

You can replace one as long as the others are in spec. There have been many many long posts about that.<br /><br />The number one thing is to fix the cause of the current problem. A damaged piston is NOT the cause but rather the effect of something else gone wrong. <br /><br />You cannot believe how many times a powerhead gets rebuilt / replaced and the exact same thing happens again.<br /><br />Fix the cause - not just the effect!
