    I have Fundeck 187 with Yamaha 115 and have similar issues with planing. Boat ran great in Florida (salt water ; no bottom paint) but when we moved to Montana, performance dropped significantly to the point it will not plane with 6 adults.

    Installed trim tabs but no real noticeable difference. 

    Would any of the following make a difference? 
     - change from salt water to fresh water
     - increase in altitude from sea level to 3000 feet

    Currently running Yamaha prop with 16 K marked on it. I assume this is their K series prop at 16 pitch. I believe size is 13-1/3". Would a different prop help?

    Thanks in advance for any suggestions.
