Reminds me of when I was a Johnson outboard dealer. A guy brought a whaler in
with a 40 Johnson, for a tune up, saying it lacked power. I tuned it up and
ran it in the tank & it was fine. He brought it back saying it still wouldn't
plane the boat. You guessed it. The foam was totally full of water. Had to
remove the floor and tear it all out. A good indication of this problem )
also when your trailer tires are flat & still have plenty of pressure.g
