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??

Sounds crazy but this is common practice on outboards. Some people increase the jet size on the holes with bigger pistons in them. You might want to ask this question on the outboard forum.
