Question about Boating
2 strokes have oil in the cylinder so a compression test may not show bad rings. But, having said that, it should have at least 100-125 psi. Most will be higher. Look for a weak cylinder. i.e.: one at 120, all the rest at 150.

I run a 175 Evinrude set up similar to this one.
If there are no warning lights or warning beeps you will have a restricted fuel filter or fuel line.
The reason you can throttle up slowly is because it takes less fuel flow to get to that point that way.
And at full throttle it takes more fuel flow to maintain speed.
If there are warnings you will need to get it scanned to find out the cause and have it repaired. Warnings can slow down the engine to help prevent engine damage.
