Other 1995 750 Stupid Chicken

[mrfist9]

So despite having (uh let me count) skis in the stable, only keeper couch is the triple B1. Lady asked WHAT DO I RIDE. I dumped her 97 GTI end of last season. I was just tired of moving it around frankly.

I was between 3 options;
1997 Seadoo GSI (low key miss my Kawi 1100SPX ironically bought one to flip after buying this chicken)
A buddy had a teal B2
....superchicken??

Saw one reposted from a guy I vaguely knew, shot him a message he came back with a price I COULD not refuse... or so I thought.
$500

Expectations weren't high for the cost, but knew it was on water last year. He was super transparent about it needing love to his knowledge not a ding on him and it was complete. Stated it needed some hull repairs, exhaust outlet & Bendix.

Alrighty got it home!



Spent some time doing as you do playing with sitting on it with buddies envisioning summer.

Various crap paint repair and glass work in spots.... More to come.

We did a tuning session with a buddies 550SX we had just finished a full rebuild and refresh on and ripped this 650 out.

Bendix & flywheel are gross, motor was seized, easily broke free. Sure it runs great maybe for another project. Also has the late 650 goodies.




Gave a few spots the classic quick polish job to see what we're working with. Came out good.



Next day:
Clean this cow.



Got this disgusting exhaust goop out

Removed all the clapped turf and mat thing




Flooded the hull, wanted to find all the leaks.
This is where we find out what $500 gets you



Found basically 6-7 devastating cracks, 3 of which were splits though the hull and either weeping or maximum drainage. However Very faint drips out of the driveshaft tube despite there probably being 30 gallons+ in the hull. Banking on doghouse is okay, just needs new DS seal (which is pretty ugly)

Sanded them all up

Whelp so here goes my first ever fiberglass job. No idea what I'm doing but I think it all came out decent. Overkill fixed all the cracks... I hope. And did 4 single layer reinforcements. That split down the side of the nose was genuinely one of the most arduous things I've done yet in watercraft.

Used TotalBoat Epoxy Resin Medium, 1708 Cloth






Painted a few sections on the exterior swiftly. Not chasing perfection here maybe one day if we love the thing. Just wanna ride!

Just a stack of Rust-Oleum rattle cans, should probably use a 2K clear but meh.







Nothing crazy but I'm proud of it!

Hope it holds up. Definitely not planning any crazy jumps.


Gonna put 440SX on hold....AGAIN
utilizing that couch 750, gonna do single 44, unsure on pipe at the moment, seadoo waterbox for sure.

Great thread man. It's a valiant effort saving these vintage 2 strokers. Nice job on the fiberglass patches - perfectly functional. Did you use Rustoleum appliance epoxy for rattle can?

I SURE did.

I used the standard white primer
Then the appliance epoxy to match. Then some random duplicolor clear I had laying around



Ripped the ugly turf off the hood lid, gave it a polish. finally got to see it all together get a good luck of it cleaned up.

Nice work !

 

[mrfist9]

Installed rad dudes exhaust outlet.
Kind annoying straight up isn't straight up but whatever nobody but me will notice.




Prepped the motor. Really wanna plop it in... But want the hull to cure a little longer and hose it all out. Maybe flood it again.. kinda scared to find out.



Just a couch small pin 750, stock bore
R&d manifold
Single SBN44 off my 701

Should hopefully be good for my purposes here.
Lady and cooler hauler.

CDI has no revlimiter, there's a timing advance in there. I probably should care but really don't for whatever reason.

You might want to consider reinforcing those stringers before you drop that engine in there, most of them are cracked , I know both of mine were .

curious if u ever had an issue with your engine hoist chain spark plug configuration stripping the threads .. ?? I really like the idea for mounting the chain , can u do tripples too ??

I did a layer over the front ones, patched a crack in the rear, and some overlap on both of them with the layer I did back there. I will definitely monitor. Definitely not planning on airing the thing out or riding it too hard, hoping it'll be fine.

I've never had an issue, that hoyer lift has yoinked just about everything that way, kawi triples, yam triples, seadoo 787/951, the smaller 2cyls are a walk in the park. I'd reckon if you had an issue that head is trash anyways.

Straight out of the Seadoo manual

Yes it will easily do triples, matter of fact that is mostly what I use them on , but I usually use two of them on a triple with a chain in between , it makes it easier to get the engine angle just right .

I probably went overboard on mine but I made a mold out of plywood and plastic sheeting and made stringer covers or caps if you will , then I glued them down to the stringers with epoxy and cabosil.
