Re: 69 merc 800 ignition maintenance
thanks guys I kinda figured that was the case I was just wondering because I was going to do a full tune up figuring that it was like a car engine till I saw those prices. I hadn't run it for about 6 months because had to get some new controls and replace the impeller and just didn't have the time or cash so when I finally did get it fixed and started it was running a little rough but i think it was just old gas and it needed to be run wot for a little while. took it out the other day and ran great and when I was flushing it after I noticed it was idling a lot better. so I guess these parts do last a while considering these are the originals
