    1996 SL780 restore from dead, junk pile freebee

    Hello all
    My friend had gotten a 96 sl780 given to him in a barter trade. It is complete junk and I couldn't stop messing with. Now its in my yard! LOL

    Here's the story as I imagine it:

    The jet pump locked up on the previous owner. He probably didn't know what was wrong and thought the motor was blown. Someone then started taking the heads off and every bolt within reach was either loosened or removed. Gas tank was taken out and even the sending unit bolts were removed. All hose clamps were removed.
    They must've stood it up on end and broke the turn cup and trim cup. The jet pump was then ripped off the back and hull damage was done.
    It then sat for years (last registered in 2005) with no hope.

    A few days ago, I was at my friend's house and decided to mess with this thing. I asked that he grab his jumper box and maybe some oil. He came back with a quart of quaker state trans fluid. Since the heads were off, we poured 1/2 a quart down the cylinders.
    Hooked up the jumper box and hit the starter. It clicked and the crank moved about 1/2 a degree each time. I thought all hope was gone, but after about 100 clicks of the starter button, damned if it didn't turn a full revolution, and then turn over better and better until it was sounding perfect!
    I grabbed the heads and bolted them on. We were missing 2 head bolts and 1 head gasket, but capped it up anyways. Poured the other 1/2 quart down the cylinders and went inside for a beer break.
    Came back out and she was cranking over great. Put a spark plug in each plug wire to check for spark and sure enough, there was spark.
    Few more beers later...
    Poured some gas down its throat and she fired right off! Smoke was everywhere!

    So now I'm the owner of this thing and its in MY yard! LOL

    I worked on it about 5 hours yesterday just cleaning it up and removing the wasps and wasp nests. Got her running on gas being drawn out of a 1 gallon evenrude oil container and connected to a car battery with jumper cables.
    Taken the thermostat out, Oil tank too.
    The gauges weren't working and neither was the kill switch.
    I took the kill switch apart and traced the wires back to the electrical box. I opened it up and traced the ground then I traced the black/yel wire from the kill switch back to the box. Somebody had put the black/yel wire on the wrong connection! Doh!!! I found where it was supposed to be and bang! My kill switch works now!
    Looked at the electrical box closer and there's a glass 1/4 amp fuse. Of course its blown. Quick run to napa and I get a 1amp fuse for 88 cents. BOOM! My gauges light up and everything is working! Even says its charging! LOL

    I plan on keeping the oil injection 'bolted up' but the lines will be connected to themselves and I'll just fill the lines with oil and it will just circulate oil and not inject any. This way, the pump can remain bolted up and not burn itself up from running dry.

    The rear fiberglass should be easy to repair. I'll post pics when done.

    I just got done taking the jet pump apart and all bearings are out.
    Shouldn't be too hard to order these things online.

    It needs new steering cup and trim cup. Everything else I have.

    More to come....

    Could someone please tell me where to get the jet pump bearings and seals?
    All the kits I find are like 50 bucks.
    Isn't there a place that sells the bearings for like 8 bucks a piece?

    $50 seems about the market value. The seals are important to replace as well, and are somewhat pricey.

    Bearings shouldn't cost that much.
    The problem is, these companies tape two bearings together and add a couple seals, put it in a box and charge ten times what the parts are worth.

    For example: http://www.globalindustrial.com/p/mo...FZA7MgodekIAKA

    I bought good FAG bearings for mine and they were around 11 bucks a piece. I could have gotten cheaper bearings if I wanted to. I think the seals I get are 4 or 5 bucks and the o rings are less than a buck a piece.

    I just found them. LOL
    Someone had posted a Daemar seal number of 30557. That translates to 30x55x7. Pretty sneaky! hahaha
    Its type A and I doubt the double seal is necessary.
