1900 sr2??? or so thats what ive been told.. - Maxum Boat Owners Club

snowridr63 · 07-03-2018, 01:36 AM

Hey guys i'm new to the forum, i could really use some correct info on my boat. Long story short, I picked it up what I was told is 1994 maxum 1900 sr2. Its in rough shape (scored a running boat for 300$). Has a 5.0lx that ran mint in the fall. it needs a full interior and a floor. Okay short story over. Its almost a year later... the floor is about done and i'm working on reconstructing the rear bench seat frame. Amongst that i'm also working on the engine and outdrive and what not. I pulled the HIN number turns out the boat is a 93' but heres the kicker, it has a first gen alpha one drive on it? Hmmm somethings not right with that picture. I'm also dealing with a **** show of wiring mess thanks to the po being a shitty home electrician. the issue Im running into is that I legitimately cant find any information on this boat model let alone picture of the damn thing on google (looking for a good interior pic) i can give to my upholstery buddy.
Also the HIN: USPA40MYA393
And this is the number i found on the outdrive 0C38079

What makes you think the drive is a gen 1 Alpha?

My 00 Gen 2 has studs where the drive mates.

So all studs between upper and lower sections of the drive?

Raw water inlet has the two piece screw in inserts?

Smaller raw water pump?

From what I recall they can be swapped but the bellhousing would need to be swapped as well. My guess is the original drive went up and the OP got the old drive cheap.

Yes all studs between upper and lower sections, im not sure about the sea pump... I ordered a gen 2 sea pump kit, ill find out if it fits when I pull it apart. That was my guess as well too mike. I am curious about the too bolts that appear to be JB welded into the transom (see pics). is there a big size difference between generations or is there a bigger issue going on?

mmwjr · 07-03-2018, 02:16 PM

Not sure why the P.O. would need to JB these. They connect the inner and outer transom assembly halves. He would not have needed to change the entire assembly just the bellhousing to install the A1G1 drive. If he did change the entire assembly he would have had to pull the engine.

Looks like the gimbal ring is the newer A1G2 so I don’t think he changed the entire assembly.

snowridr63 · 07-03-2018, 03:38 PM

If you look closely at the pictures of the inside and outside of the transom you’ll see that there are bolt holes on the I believe is the bell housing; inside pic (I’m a automotive tech, still learning all this boat terminology) but there is not bolt holes on the outside of the gimbal assembly. Which is leading me to believe that someone half assed the **** out of this and only changed the outside portion of the stern drive to make the gen 1 unit work?

mmwjr · 07-03-2018, 03:57 PM

The bellhousing is the part that the upper drive attaches and pivots up and down, the gimbal ring turns side to side and attaches to the outer trans assembly.

The outer transom assembly has only studs or bottom tapped threads for bolts, no through holes as that would provide a place for water to leak.

snowridr63 · 07-03-2018, 04:11 PM

after looking closer at pictures online I believe this si what they did. they changed the entire outter portion of the transom to make a gen 1 fit and probably cut the top studs off so it would fit in. the reason I think this is because from pictures it looks like the top studs are wider on the gen 2 vs the gen 1. also there are no top studs or bolts holding the outter to the inner

He must have gotten these parts for free to go through all the effort.

LOL. I see that for a well now. But why don't ask the question on that way then?

sorry that was my bad, I just wanted to make sure that my suspicion and research is right about the stern drive before I went and dropped an ass ton of money on the correct stern drive. Also is the 1.47 gear ratio correct for the 5.0lx mated with a gen 2. again just want to make sure what im reading online is correct
