    Trying to reprop, but how can I tell if my engine gets to WOT?

    if you went from a 1.62:1 drive behind your 250 cubic inch motor to a 2:1 drive, and you were turning 4500 RPM before, you would be turning about 5200 RPM which is grenade the engine territory either you messed up the throttle or you have a different drive ratio than you thought

    Filling coolant reservoir 3.0 TKS?

    if your coolant is green, you add green to it if you coolant is orange, you add orange to it if you cant figure out the color, you change it and follow the manual if you just need to top it off a bit, simply add a few ounces of water.

    Chevrolet Demon 5,7 l marine engine

    without a year, cant help with the model. however I am speculating...... if its an AQ271, or an AQ290 or AQ311, it would have a holley 715 CFM 4150 carburetor that the prior owner could either have swapped out the bowls for Demon Carburetor bowls. hence the confusion. Again, I am speculating...
