    1992 Sl 650

    Hey guys, First off just let me say thank you GH for this wonderful forum. I've already got a lot of good information out of it so far. I just picked this thing up a couple weeks ago. The guy had never had it running since he owned it. I got it home and messed with it for a while and got all the electrical components hooked up and tested and finally got it to crank yesterday. I don't have any pics yet but I should by tonight. As of right now I don't think I'm getting any fuel delivery so that's my next thing on the list right now. Also if anyone has a throttle lever for sale lmk. Thanks guys.

    Welcome to the Hulk

    The 1992 SL 650 was the very first year for Polaris PWC.

    The early PWC model years 1992-1993-1994 were a learning curve for Polaris, so there will be some things that are different on your 1992 compared to the later model year SL 650.

    Your jet pump is the non-modular 146mm type (1992-1993 only).

    If it is original, your engine crank case has water cooling. If it was not winterized properly, the crank case is prone to cracking from water freezing inside. Later version Fuji crank cases without the water jacket can be used instead, if yours is damaged.

    I think the routing of the cooling hoses was also revised by Polaris in a service bulletin.

    The fuel tank venting was also changed in later model years.

    Original fuel tank filler necks and gas caps can crack and leak. You can upgrade to a newer Polaris version, or even a Sea-Doo part.

    I just bought a Polaris PWC - what should I do?
    What to do to get it running, keep it running, and avoid potential damage

    Thanks man. Yea I'm still trying to adjust my learning curve to the older version. It's going well so far, I just finished getting the carbs off for a rebuild. I've messed a lot with jet boats, but this is the first ski that I've really messed with so it should be interesting!

    The carb rebuild kits have the parts for one single carb, so you'll need to buy three of them. Also note that the carb kits have all the parts to cover multiple configurations that were available for the Mikuni carbs. So, when you get done rebuilding them you will certainly have parts left over.

    HELLPPPPPPP! Alright I got the ski running good finally and went to do a first water test and I found a crack in my block. It appears that it doesn't go all the way through though. Is there any way to fix this without taking the entire motor out. I'm thinking JB Weld? Any advice?

    Where exactly is it cracked?

    Photos?

    How much water was leaking out when the engine was running?

    Did you water test the engine on the garden hose before taking it to the launch?
    Did you run it on the trailer at the launch?

    On the exhaust side of the block, I'll try to take a pic. I did water hose it before and just did not notice the leak and yea I was on the trailer and saw it.. Its not to big of a leak when it runs, but the leak doesn't change either running or not.
