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?
I assume normal rpm would be about 4800? <br />Could be throttle cable needs adjustment or is going bad. Did mechanic possibly disturb this while servicing unit?<br />lower unit needs inspection for sure.
I'm not sure that "hope will float"...<br /><br />My OMC Cobra was "serviced" by a "professional" twice.<br /><br />1st time they didn't bother to put oil in it at all. worked for about 10 min.(they replaced the drive of course)<br /><br />2nd time serviced by a Four Winns Dealer "professional". They filled it improperly. Went for about the same ....10 min.(they replaced it also).<br /><br /><br />Third (and subsequent)time? ME.<br /><br />I'm slow but I eventually learn.<br /><br />Regards, <br /><br />Rick<br /><br /><br />
