So, it probably qualifies as a SHT, but I will post here anyway because i need some info.

Coming back from a successful ocean fishing trip today, and almost back to the ramp, I hit an unknown submerged object and just trashed my outdrive. I had cut the end of a jetty kind of close, but had made it all the way past the jetty, and was in 48 feet of water when there was this horrible noise and all forward motion stopped. I went back to see the top gimbal pin sheared off and the drive sort of hanging at a funny angle. (funny, ha, ha...) Anyway, I dropped the kicker into place and started heading in without even a thought to the fact that I might be sinking. Well, a few moments later, I realized I was standing in several inches of water that was rapidly getting deeper. Ack!

Long story short, I mayday'ed the coast guard and they sent a tow boat out to help. (Not before several different idiots walked all over my radio transmission asking the CG for a bar report on channel 16!) I got towed back and bailed/pumped out and the CG helped get the boat onto the trailer. Many, many thanks to them! Had I sunk, I could have swam to the jetty, but they saved my boat from a certain watery grave! I still don't know what I hit. I looked at my GPS track later, and I was 150-200' past the jetty and should have been in open and deep water according to the charts and the depth sounder.

However, now I need a new outdrive in a bad and urgent kind of way. The boat is a 72, so it is a pre alpha. Most of what I see for sale is alpha of one kind or another. Can the alpha be put in in place of the old style? What would be involved in making that swap? Any advantages to that over the old style? Anyone in the PNW have an old style 1.98R pre alpha drive (complete with gimbal!) that they want to sell ?

Re: need new merc drive

You better take a closer look at the back of your boat. You need more than a drive.
My guess is the drive has the least amount of damage. But you still have the gimbal ring, the bellhousing (pivot housing), and the transom shield that are probably broken.

Yes the leg itself is the least trashed. The gimbal housing is toast. The plate on the inside of the transom looks undamaged at first inpsection, but everything that was outside the transom is wasted. Well, the lift cylinders look OK, and miraculously, the hydraulic lines are intact. The skeg is chewed up as is the prop, but the prop still turns quietly anyway. I still think I should replace the leg though, if for no other reason than to get an intact skeg again.

But that gimbal stuff is in many pieces, some of which are not present...

You can use the Alpha but not the Alpha gen II. It's (Alpha) a direct replacement. It's a slightly better drive. I believe there was some bearing, gear, and shaft changes.

Re: need new merc drive

:% I would start looking on ebay, that is where I picked up two of them last year.....
I used one for the new bell housing, the rest was not usable because of degradation @ the pin between the steering arm & the gimbal ring itself....
The other is in such good shape that I cannot part with it as I will use it to repower, sorry....
Anyway, my point is that you need to ask if the steering arm is tight before you bid.....
Any transom assy from an 888 will work as a direct bolt on replacement.....
In fact any transom assy with the non threaded hinge pins should do....
See if they have a s/n before bidding
Good luck with your search.......JK
Glad you didn't sink!d:)

Re: need new merc drive

You Could swap in an Alpha Outdrive to the Pre-alpha transom assembley,.... As long as you use the Shorter Input Shaft that's on the Pre-alpha........

Swapping an Alpha Transom assembley onto the Pre-alpha transom assembley that's still Inside the boat will present Several Fitment Issues..........As will swapping in a Complete Alpha transom assembley,.... Then you'd need to change the Flywheel Cover,+ the Exhaust manifold.......

I'm pretty Sure that I have some of the Pre-alpha transom assemblies laying around somewhere,.....
Drop a line to bond1o at godotcom...... put "Boat" into the subject line or it'll be deleted........
Maybe I can help you out.......

Re: need new merc drive

Thanks for the help. I am going to look at a transom assembly later this week that I think is the same as mine. If it is too new, I will be emailing you, Bond-o. Is there a way to tell the difference between alpha and pre alpha without the numbers being present? Mine and the sellers have no numbers in the correct place on the gimbal housing, and the seller doesn't have the leg that goes with his transom assy so I coudl get the number off of that.
