I bought the new prop (14.5x19) directly from Volvo Penta. The boat is pretty much empty right now as we had planned on selling it before realizing something seemed to be wrong with speed and power. Can you tell me more about the foam being waterlogged? How do I check this? This is my first boat, and although we have used it a lot, all I have done is the routine upkeep, etc. I am learning, but some of this stuff is beyond me right now... Thanks for any and all help!!
