    Could a 4 blade actually be faster?

    put a certified laser tach on that motor to verify your RPM's. you may want to do some reading on the GM inliners over at http://inliners.org/ if you want to understand why these motors dont go above 5k without serious valve/lifter/cam/head/intake work

    3.0's wont spin a prop above 21p just not enough motor there for the 1.98:1 so the 23p is not going to happen the stingray 185x weighs 2200# which is a lot of boat for that little motor.

    Gauges

    test the gauges and the sender. gauges like fuel gauge and temp sender read 240 ohms at bottom of scale and 33 ohms at top of scale agreed, a bad ground will cause issues gauges can be repaired, however cost to repair gauges is about 5X the cost of replacing.
