HELP! I have a '99 Centurion V-Drive & can't locate all the blue plugs on the engine
 

I can only locate three blue plugs to empty the water out! Last year when I winterized it, I could have swore there were at least four. I found two on the passenger side and only one on the driver's side.

Is there any more, or have I just gone mental?

If its mercruiser ski... Mine has 6. Starting from the bottom- 1 for fuel pump cooler, 1 on each side of block, 1 on each manifold, 1 just past the recirculating water pump/thermostat. Get a flashlight and stick your head down in there

Found them all! Thanks :) I could only find the ones towards the bottom by moving the wall over that lies between the motor and storage locker. It's winterized now and put away :(

4 or 6? Just out of curiosity
