lady mechanics

I love boat engines but dont know enough to not break them even more by fiddling and find myself at the mercy of some testosterone male saying "hey little lady, dont you worry none, I'll fix it". Part of you wants to brain him with the spanner you're wielding, but you know to get it fixed will take knowledge and money unless you comply and hope its unconditional.

Calling capable women  with engine skills! Whether self or course taught, it would be good to start a network or pool to share knowledge and ask questions. My first question is what course would anyone recomend for basic engine maintenance?
