Cheap man's vacuum pump - lower unit check on a budget

[bben76]

Well, after an extensive search online for a lower unit vacuum pump, I couldn't find anything.

Didn't want to spend a lot of money, but needed to check my lower unit as I just replaced the seals.

All I had was a vacuum/pressure gauge used for testing automobile vacuum pressure and fuel pressure.

Took me a while, but after sopme experimentation I found the best plunger mechanism is a caulk tube.

Worked great! So thought I would share.

Here are some photos.

Thanks for sharing Ben. Always good to see American ingenuity at work...d

I'm going to move your thread over into the "Outboard Discussion" forum so that more folks can have a look at your handy work.
