    Default "Justin, what do you have it h

    "Justin, what do you have it hangin' on. A 9.9 will push a 14 foot aluminum (200 lb boat) at maybe 15-20 mph, that's if it's loaded light.

    Your prop may be a low pitch, your carb may be a little clogged, your compression could be shot and any number of 1000 other things.

    If you have it on the back of an 800 pound fiberglass boat and your buddy's 8 is on the back of a 12 foot aluminum, I would expect him to blow your doors off....

    Maybe it's working exactly as it should.

    Test the compression as a starting point - should be near 100 at both cylinders - that's your starting point...."

    A "professional" is someone who gets paid for their work - it doesn't necessarily mean they are good at it :)
