5.7 mercruiser alpha one with full throttle today only got to 2200 rpm or 23 mph. Noise from lower unit louder than normal. Boat ran ok but no speed at full throttle.
I have a 5.7 mercruiser alpha 1. Today with full throttle down the boat didn t go more than 2200 rpm, approx 24 mph. Its gone over 45 mph last year. The sound in lower unit is louder than normal too. What could possibly be wrong?
