can you resleeve a 1998 base 150 merc??

[TThornhill]

hello, first time here. been searching around for some answers, and figured i would give this a try. recently ran into a issue with my boat motor, found it to be getting horrible gas milege and figured it would be good to do a compression check. all cylinders was decent, but one was a 0! crap. took the head off and preignition had occured. i understand that you can just repair the one cylinder only. my questions is that instead of boring out and using a different size pistion. is this type of motor one that can be resleeved so that it stays at factory bore? the cylinder walls took a little beating and will require bore or resleeving. i would feel more comfortable having the sleeve replace, but thats just my thoughts. any one have any suggestions as to what would be a good idea to do? good place to buy sleeves (if it applies)? i will be performing the repairs myself (besides any machining that might be needed) as i cant afford the $2500 + that it would cost have someone do it. just a little info on the motor, its a 1998 mercury 150. carbed.2 stroke. believe its a base model, no xr or anything like that, v cylinder. its on a same year hurricane deck boat. if any one can help please feel free to reply.

If it's a steel bore, you can bore it and put in an oversize piston. You can put in just one, and you won't notice the difference.

If it's a plated bore, you can clean it with acid. Unless there's been a broken ring dragging on it, or it's otherwise had the plating trashed, it'll clean up like magic.

Boring is cheaper than sleeving and you can bore up to .040 oversize to clean it up.
