OMC Electric Shift Won't go into reverse gear

I have a 21' Apollo with a OMC outdrive that shifts into forward with no problem but doesn't even try to go into reverse . I have checked the ohm readings to the solenoids and they appear to be fine. I have also checked the readings from the shift box and it is sending the correct voltage back as well . <br />Is it possible that the drive has to be all the way down in order for the unit to engage into reverse or is it just a case of a bad reverse solenoid ?<br />Any help or similar experience with such problems would be muchly appreciated .<br />Thanks

You do have the correct oil in the lower unit? Those units used a different oil in the lower.

I have the correct fluid in the lower unit as per spec. in the manual that I have . Thank you for the reply though .

Bigmarkor,<br /><br />I had a similar problem that turned out to be a broken spring. Here's how my mechanic had me diagnose it:<br /><br />1. I connected a volt meter between the shift coil wires (behind the engine port side) and the block, one at a time, then shifted into forward and reverse to verify the shifter was sending 12V. If I'd gotten no voltage from one or both wires, I'd have had a wiring problem from the shifter. Since I got 12V with the shift lever in both positions, I continued to step 2.<br /><br />2. I checked the coil by connecting an ohm meter between the reverse coil wire going into the upper drive unit and the engine block. No continuity would have suggested a bad coil or lead. I got continuity, so I checked for a broken spring.<br /><br />3. I reconnected the shift coil wires and, WITH THE ENGINE OFF, I manually rotated the prop clockwise, while an assistant shifted into reverse. The prop should have stopped completely, but it didn't, so I had a broken spring.<br /><br />Reverse problems are a pain because you have to dismantle everything to get to them. But, with that said, my mechanic had it repaired in a couple hours.<br /><br />BlackSmoke
