    Thanks, I was trying to figure out the best place to start a new thread, I’m still trying to figure exactly what she is, 300 dB of some sort I think.

    After some looking on eBay and other places I guess I don’t have a sedan bridge but a 300 sport bridge. Any way I got the tranny’s off the old engines one seems to work as it should when I tested it with a drill motor, the other one the input shaft is locked by somthing, the shift selector is stuck as well. Both have the same input rotation so I guess one runs in reveres for the counter rotating prop? Is that pretty common?

    After seeing your pictures and your mention of visible rot, I strongly urge you to get the rest of the boat inspected for rot particularly in the stringers, transom and foredeck. Theses models were prone to stringer rot and it has been exposed to the weather for the past ten years. Plus it's 40 years old. You don't want to start your restoration only to find out down the road that engines have to come back out to repair rotten stringers....or worse yet, discover the boat is not restorable.

    I truly hope all is well and I don't want to dampen your spirit and enthusiasm, but you really should find out now. I just spent 3 years restoring/refurbishing a 1985, 23' Cobalt cuddy cabin so I have a bit of an understanding what you are about to tackle. My early estimates were about $5-6,000....I spent $19,000 doing most of the work myself.

    Get it inspected before you spend another dime. Best of luck....I hope it all works out.

    Thanks for the advise, I have no intentions of redoing a rotted out boat. The boat is out of weather now while I’m building up the running gear which is the main reason of the purchase, the boat was free with the crate engines basically. My Initial intentions was to put the engines in a Bertram, but this boat actually fits the needs I’m looking for which is fishing. The rotted part I mentioned seems to be from the theaft of the genset. I believe they ripped it out of the boat leaving exposed wood. Time will tell, I hope she turns out to be as good a shape as it now appears but if not I’ll go to a plan B

    Well I answered my own question about the trans. The reduction gear on the back of one reverses the input direction, which also the one that seemed to have got some water in it at some point in time. But it’s quite repairable

    Second look, both transmission are the same and turn the same direction, both props look the same and was already removed from the boat. Maybe it didn’t have opposing props?

    Some of the early Sea Ray's had GM engines where one turned in the opposite direction (reverse) of the other engine to achieve counter rotating props. If you can crank the motors over you can see direction from the flywheel or removing the distributor cab. If you have counter propellers it may be from the engines. Also, you can look at the props and observe the blade direction. If the trannies are the same counter-rotation will come from the motors.

    The motors are gm 6.2 diesels, the pumps on the velvet drives are oriented for the same input direction. The props was already off and honestly they look as they could put on in either direction. I’ll get some pictures of the props. They look as they could go either way.

    Both props are counter rotated so I guess that’s what it is, for now any way. I got the the transmission cleaned up and ready for reassemble once the parts arrive, it wasn’t bad at all, really all it needed was a gasket set, all the cluches and plates look unworn.
