I have a 2001 Johnson 70 HP motor on a 2001 19' Lowe roughneck boat. I purchased the unit last fall from a couple getting a divorce. They had used it only once the previous year and 4 times the year before. We had a real hard time starting it when I went to look at it origionally. I checked the compression and it was fine. I brought it home, ran sea foam through it and had no problems. The other day I was out and it ran great then for no apparent reason it just seemed to bog down. I got it back and checked the plugs for spark and/or fouling. They were all fine. We drained the bowls thinking maybe something was in the gas. The next day we checked compression again (all 3 cylinders were good thankfully), put the muffs on it and started it up. It ran fine. I decided to take it out again yesterday and it ran great for about 15 minutes. Then it started to run slow again. If I would keep choking it, it would run full speed. My ball does seem 1/4 to 1/2 flat (definately not tight) but it doesn't help to keep pumping it up. It just seems to be not getting enough fuel. My assumptions are the filter may have junk in it or the fuel line or tank may be sucking air. What do you guys think. Should I try replacing those items or just bring it in to get serviced. My thinking is since it sat over night and then ran good agin it may be just not getting enough fuel for some reason. It does start fine and idles fine, it just doesn't have any top end power. I have no problem just motoring around at the low speeds.<br />Thanks!<br />Brent
