I have 1994 Mercury 90HP, mainly used in saltwater. 2 weeks ago head back in felt like my engine was going to die at full throttle. So, I had to down throttle to stay under 2000 rpm. Another day, turn the outboard on land motor sounded louder than it ever sounded before and water pumping faster than usual.

If anyone can give me any ideas on what the problem is or how to fix this problem very much appreciated.

Help me save a few bucks.

Thanks

Mine sounds like crap on the muffs, but sounds great when she's in the lake.

I think it's just the open exhaust echo that makes it sound so bad on land.

Before it was loud, but its abnormally louder than before.

May I add to my original post that the outboard also vibrate hard.
