Howdy, I'm new to the forum, so here we go.... I have a 1976 Invader 19ft with the 190HP Ford 302 and the 800 Electric Shift outdrive. Last summer reverse quit working all together. Prior to that it would work as it pleased. When it went out last year, it sounded like a clunk from the outdrive, and it stopped and stalled. After that if you put it into reverse it would go forwards, fun fun. I plan on working on it over spring break. Here's what I know right now. Last week I pulled the shift wires to see if they were getting voltage, both of them were. I then checked the resistance on both coils. The reverse coil is reading 6.7ohms and the forward coil is reading 6.8ohms. I put 12 volts to the forwards coil and the prop wouldn't turn counter clockwise, which let me know it was working, I then applied 12 volts to the reverse coil and the propeller would spin freely in both directions...... I'm thinking it's the reverse spring... I could be wrong though. I plan on pulling the lower unit apart next week to see what's inside, and I was wondering if anyone has done it without special tools, or if it is absolutely necessary. Any help is appreciated, thanks.
