I purchased a boat with 500efi's a month ago and all off the drain plugs were out of it for the winter months. My dumb questions is how many blue plugs are there per motor and where are they located? I just want to make sure I dont miss any of them.

1 on each side of the block, 1 in the fuel cooler,
( bottom r/h side of the cooler) 1 in the elbow of the
hose going to the recirculating water pump

item # 11 in this pic is it on the fuel cooler

Thanks JT! You going to make it to rathbun this year? Hope to see you there!

happen.

Right now, I got enough stuff cooking, mine probably
wont hit the water til sometime in may.
