1. The leads come out of the exhaust housing through the hole where you would normally access the shift rod coupling. Then up along the backside of the exh housing (inside the lower cover) and clamp at the cylinder head. There are rubber sleeves covering the disconnects

2.Yes, you can check the resistance between each lead and ground. I’d have to get the book out to see what it is supposed to be (4 Ohms???)

3. Yes, continuous power is required to hold it in gear

4. Yes, you can apply 12V to each lead and ground. If running, clutch will engage and prop will turn. If on a stand, clutch will engage and lock the prop in one direction only. You will be able to turn prop in other direction with some drag felt.. WARNING–never apply power to both leads at the same time while running. Something will bust if you do.

5. WRONG. The Hydro=Electric shift defaults to forward. Yours defaults to neutral

6. They actually are pretty reliable. Killers are water in gearcase (rust) and poor electrical connections (rotted wires). Shift switches in the control are hard to get and $$$$
