    No problem.. On all new fourstroke outboards ive been noticing they trap air pockets and if you pull the dipstick without cleaning it first and putting it back in then pullin it back out to get your reading you will get a false reading.

    Depends on, hull design, horse power, weight, and rpm at wide open.. To accurately fix your situation a tiny tach is going to be needed to find rpms

    The suzuki V-twin is a different animal then most other 25hp motors, it has alot more lower end torque and will need a larger prop then most because it also has a slightly lower redline. Definately get a tach and see what it is at full throttle. Are you running the stock prop?

    What did your dealer say? 12 hours, can't be out of warranty yet.
