Blue plugs

[bg75flh]

Can any one tell me how many of the blue drain plugs I need to find. So far I have removed 5. 1 on each side of the block, 1 on each of the elbows going to the exhaust rizer, and 1 on the bottom of the water pump. Im surprized the mercruizer manual didnt even mention them. I have a 2000 with the 5.7L and open raw water system.

5's it....did you mean the ones under the risers at the bottom of the exhaust manifold??should be one each there....if you have an electric pump...probably one or two there also...

Thanks for the reply, And yes I ment the ones on the elbows going to the exhaust. No elect pump on mine, Just the belt drive one. I think I will go put the plugs back in and fill witth RV antifreeze for extra insurance.
