HELP NEEDED! Unwinterizing my boat and can’t remeber where this last plug goes!

[Gwojcik7]

2007 SANTE. PCM 330. I’ve got the two exhaust manifold screws back in, both knock sensors back in (one of each side), the transmission drain back in, the 9/16 circulating pump screw back in, but have a 7/16 plug left and can’t for the life of me remember where I pulled it! And yes I know I should have just put it back in when winterizing after water was drained. I’m 3 hours in and out of ideas. Please help!

Sounds like the Transmission cooler plug.

When you say transmission drain are you talking about the v-drive. It should have a plug but mine’s a male square drive sort of thing.

There is a spare plug!

It does sound like the tranny cooler as mentioned before. It should be a black cylindrical piece. Did you use the manual as a checklist?

One way to ultimately find out is to check for water once you've started the boat, which is good practice anyway.

Not sure about yours, but like Greg said my 2017 450 has a spare plug as well, screws into a spot on the top left side of the motor.

You should be able to use manual to check what is missing....worst case, start her up for 30 seconds and see where the water comes out

Transmission cooling plug it was! Hiding on the starboard side under the exhaust manifold. You guys rock thank you!!
