Posted on here a while back. Been trying to find how water was getting into my Champ for a month or so. Everyone had some good advice for locating it and I tried all of them. Never saw anything coming in but every now and then I would turn pump on and get up to 5 gallons out. Took it fishing yesterday and laid across rear deck and watched for around 15 -30 minutes twice. Nothing. Finally I got to noticing it happened each time I moved from one spot to the other. My biggest concern was a crack in the hull that I could not find. Finally it occurred to me. I wonder if it could be coming from the speedometer line. It has never worked. Long story but I caused it myself. When running new transducer cables through the loom coming from boat to engine I must have pinched the water line. When I checked by blowing air through water pickup on lower unit water would drip from the loom mount to the inside of the storage area and straight down to the bilge.
Well, I got everything resealed and checked out very well!
