1972 V4 100HP Evinrude woes (Did I just kill the powerpack?)

[ILLaViTaR]

Hey guys!!

Well after years and years of wanting one I've finally bought my first boat, cleaned the boat up a bit but the motor still needs some work.

It's a 1972 100hp Hydro-electric shift Evinrude that is currently missing a starter motor, tried hand starting it with no luck (grounded the spark plug on the head/tried leaving a slight gap and found no spark).

Well anyway after been constantly interupted while trying to start it I accidentally mixed the battery terminals up and put the positive on the neg and vice versa. This ended up with a decent amount of smoke coming from the power pack (towards the back left I think). What have I done here?? Melted a wire/blown a fuse?? Can I repair it or will I need a new power pack?

Any help will be greatly appreciated I'm itching to get out on the water!!! Cheers.

Can't find anything in search besides it possibly being a rectifier?

Took off the plastic cover and found a bar terminal with a line of wires screwed to it. found a red wire out of it's casing however it didn't look as though it has burned, and there was a lot of smoke too. Anyway the red wire led to a tiny cylinder thing directly under the terminal bar. Is this the rectifier?? hmmmm

A rectifier is about the diameter of a quarter, and has a red and two yellow wires.

If you connected the battery backwards, it is guaranteed you cooked the rectifier. Possibly other things too.

Thanks for the reply, do you know what other things I may have possibly cooked/should test? It's definitely the rectifier then as it also has 2 yellow wires, it gave off a lot of smoke for such a tiny thing!!
