Late last season my 21ec develped a serious stuffing box leak putting 5 in. of water in the cabin while sitting on the mooring. This came on suddenly. I repacked the stuffing box during the winter.
Come Spring launch time, I started the engine wiht the boat on its trailer in front of my house. The engine acted very strangely. It would run perfectly smoothly above about 1500 rpm, but shake violently at lower speeds, I loosened each injector nut to isolate a dead cylinder - all OK.
I called a local engine service place and they sent a guy to have a look. Turns out the motor mounts have collapsed. The engine sits low enough so that if it shakes a little it hits the injection pump throttle arm on a mount, giving the engine a jolt of more throttle; engine smooths out, falls back down, process repeats. Reallsy strange. Getting new mounts. Accounts for last seasn's stuffing box leark also.
