    v6 fuel pump vs v8 fuel pump

    I recently did a v6 to v8 swap in my regal 2100. At about half throttle I'm up to about 4000 rpm and when I give it more the engine starts to bog down until I back the throttle off leading me to believe it's a fuel delivery issue. Checked the filter, looks fine and I replaced anyways. Tried two...

    wrong prop? cavitation?

    I swapped out the 4.3 from my 97 regal 2100 (fastrac hull) for a mid 90s auto vortec 350. It used to have a 17" 3 blade prop in it with its second gen alpha leg. The gear ratio is 1.84 so i reproped to a 21" 4 blade SS. The prop has four holes around the diameter. Itll run up ok at slow sleeps...

    Bought my first boat

    I just got a 1997 regal lsr 2100 with a 4.3 L mercruiser. I know nothing about boats but am mechanically inclined. It hasn't run in 2 years. But everything should work. Where should I start to get it water ready? Oil change, hydraulic fluid change, drain gas, spark plugs? What else?
