    9.9 eptul

    Just bought a brand new pair, still in the box. Beginner question: should these EFI models be run dry of fuel each day or does it make a difference? Also, having a time finding a flush attachment. I'd like to permanently rig something that would be easy to use each day without worrying about...

    Questions on re-powering from 9.8 to 9.9 or 15hp

I am in the process of making some changes to the boat that will make her heavier a bit, and more windage... meaning I could use a bit more power.

    I have a 9.8 EPUL bought new in 2014, actually bought two, to power a 36 sailing catamaran. The motors have been very reliable. They now have about 300 hours on them.
