the 1.65 ratios came with the lower hp engines,,like the 5.7/6.2's small block chevys and the 7.4 mpi 310 hp big block chevy engines..

Serial number OK092486 is going to be a 1997 MERCRUISER BI-ROTATION BRAVO 1 1.50:1 Model Number 5120150KS.

This was a standard drive unit when it was new.

Bad solenoid?

Ok, I finally had a chance to get under there and play with the drives. When I try to put them down, port side goes down, but the starboard just clicks and doesnt move. If I put my finger on the upper solenoid (starboard side), I can feel it clicking. When I go to put the drives up, they both move and seem to work fine. Got fluid in both sides, and pressure in all the lines. Both pumps run (pretty loud).

Sounds like I just need to change the upper solenoid (which controls the UP motion) and leave the lower solenoid (which I assume controls the DOWN motion). Please let me know if I am on the right track.

This is what I think I need to buy: http://cgi.ebay.com/ebaymotors/18-58...ssoriesQ5fGear

Swap the wires on the solenoids to isolate exactly which component is bad.

Just changed the solenoid and everything is working just great. All the help is much appreciated.

These drives have hinge pins instead of trim senders. That makes them HP units. I could be wrong but from the picture it loks like it.

it should be an xr. it has hinge pins. that means it is an hp unit

Vinzi,

I am pretty sure that you can bolt any Bravo onto an HP transom, including a Blackhawk (that one I know for sure). So the serial number tells all.

Really? Regular Bravo 1's don't have hinge pins?
