1978 OMC 225 V8 to 1978 235?

[Cuyose]

I have an opportunity to pick up a spare drive for an electric shift 1978 OMC. I have a high profile 1978 OMC electric shift 225 OMC. The drive supposedly has 235 stamped on it. These sound like a straight swap. Are they?

I used to be a regular member and am always impressed with the knowledge out on this forum. it helped me get my siezed 74 Cobalt up and running like a champ. But at the price I found this complete freshwater outdrive, prop included, it is WAY cheaper than replacing seals, gears etc! I am just hoping its a pretty stright bolt up. I am fairly confident it will e. Same year and everything

See if you can track down Boomyal, he is a member who knows a whole bunch about the Stringer drives. <br />I am a Cobra guy so I couldn't say.

The gearing in the V-8 upper drives are all the same. The difference might be attributed to the motor/carb package that originally went with the drive.

There is no such thing as a 1978 Electric Shift. 1977 was the last year for Electrics at OMC.<br /><br />If the drive is 1978 it's hydromechanical shift or has been converted since to full mech.<br /><br />If they're both pre-1978 units, as long as they're both High Profile, they should be the same drive.<br /><br />1976 was the last year for a "225" which was a 305 Chev.<br />In 1976 and 77, OMC offered the 235, which was a Ford V8<br /><br />both used 1.16 ratio drives as Kieth was saying, compatible there.
