Maybe that's my problem, I aint never felt one of them there silicone boobs. I've always been preffered ole natural myself.

You ain't missed much my friend, best au natural:beer:

Well, after going over the fuel lines, filters, bulbs, vent etc everything had run fine for a couple of trips but then yesterday I had the problem again. Engine starts and runs fine for about 15-20 minutes at cruising speed then bogged down and got worse and worse. We limped to the fishing grounds and drifted a while. After that it ran fine again on the short repositioning moves between drifts and ran fine all the way home. I am starting to think it may be an electrical issue????

I would rebuild the carbs, probably some junk floating around in the bowls. You probably have some junk in your carbs from the old tank. That 115 is easy to work on and rebuilding carbs is a easy as pie. I had the issue with my Dad's Evinrude 120 and my Johnson 150. When you have junk in the carb the motor will run great until a piece of crud keeps the float needle from seating or a piece clogs your high speed jet then it will bogg down till it clears. Sometimes the debris will float around in there and the problem only occurs intermitently.

What Mulv said....my recent problem was trash in the carbs. Like you I saw just a few little bits of stuff in the filter on the motor. Didn't look like much to me but I know now that it was enough to wreak havoc on the carbs.

OK, after long last I have an update. Due to vacations and company etc I did not have much opportunity to use the boat in August.

Well, a few weeks back I had bought carb kits and took my trailer down to the marina to pull the boat and take it home to work on it. Well, a buddy of mine suggested I talk to the old guy who lives next to the marina. He used to own it and he was a Johnson mechanic for many years. So, he introduced me and we talked a bit and he said "let's go for a ride". Well, my intermittent problem of bogging and lunging was happening most times out to the point that I had stopped trying. I took him (Charlie) for a ride and as soon as we hit deep water and tried to plane out it started surging etc. Right away he said it was not the carbs. His initial instinct was ignition. We went back and forth a few times and pulled the cowel. He messed with a few things and in the end thought (without any electrical testing) that it was likely the power pack. Well, I thought the gut instinct of a 75 year old Johnson mechanic was probably good. I bought a power pack and installed it myself with the boat in the water last week. I test ran for 45 minutes with no issues. Today we went fishing and ran for 2-3 hours and again no problems. Fingers crossed it seems like the power pack was the culprit. Back in business with time to spare before blackfish season!

tough to beat those tough old birds, good call Kev:clap:

Way to go whale...all the power pack probs I had sounded same, but never up and down...all down...glad ya got to the bottom and glad to learn power pack can be on/off issue...
