Head gasket replacement interval?

[nburford]

I have a '95 Johnson 200 hp Ocean Runner that is used in salt water, and was wondering what the consensus is about replacing head gaskets?<br />Thanks,<br />-Nick

Replace when there is a diagnosed need, not a PM thing.

I have to say go ahead and bite the bullet every 4 to 5 yrs.If for no other reasons than taking a good look at cylinders,changing tstats,checking water passages and getting a coat of antiseize on those bolts.Then even though you should'nt need to get back in for awhile,you know you can without thinking about broke bolts,drilling,ez outs or retapping.
