I believe the F28 has Paragon V drives. The transmissions are all the same with the V drives. The drive ratio (1:1, 1:1.5, etc.) is determined by the V drive. Port side should be left hand rotation. Plan on rebuilding since Paragon transmissions haven't been manufactured since the 1980s. If you find you need parts during the rebuild let me know. I have a few spare parts laying around.

Thanks Dog House.the tranny seems fine looks like I lost a bearing in the v drive half. Was hoping to find used one. That's why I need to know ratio
called tyranny shop they want 4,000.00 to rebuild tyranny and drive.can I turn the input shift and see how much the out put shift turns to get ratio on v drive half

Have fun about 300 lbs of onery meaness, been there done that. Have a spare set of trannies and one good reverse rotation 318 for the starboard side. Give you a tip, once you get the tranny out take off the flywheel and have the flywheel welded in six places from the engine side of flywheel near each bolt hole.

Here is why; in cars the starter is underneath the v of the engine gear facing to rear. In marine use they mount the starter with the gear facing toward what we would call the engine front and readily visible and accessible from the tranny bell housing area. The problem arises in that the starter jams into the ring gear and causes it to move toward the engine front and eventually the starter will not engage, ergo out comes the tranny again and pain.

In the auto world the ring gear cannot come off or move as it is up against a steel shoulder. While you got it out make this fix. Just sayin!

That is why I had to pull the port v drive due to starter ring gear slipping.

If the transmission is good I would recommend just rebuilding the V drive portion. Since the engine mounts are on the transmission, it is much easier to just remove the V drive. Just make sure the transmission drive shaft doesn't pull back when you pull the V drive off the transmission. Get a flat head screw driver in there to keep the transmission drive shaft in place when you pull off the V drive and you should be fine. If the transmission drive shaft pulls back you will need to rebuild the transmission. Rebuilding the V drive should cost less than $2,000.

Is the V drive housing ruined or can it be rebuilt? V drive housings can be hard to find. I believe a 1977 used the oil cooled version of the V drive. These are some of the used ones I found on Craigslist using Searchtempest.

Not sure where you live but you might be able to find one used. Good luck.

I have a 77 and 78 f28, 78 is running and operation in water and has my 77s v drives. the 78s are setting on the back of engines beside my shop. One is LH and one RH. I do not need them, the gearing is fine, but I would install new clutches to be sure. I have checked with Bob at beacon and if you want to deal PM me.

Bot 77 and 78 are Oil cooled through a water over oil heat exchanger.
