Hi I found you guys while trying to get some information on a ski I recently inherited. It is a 97 Seadoo GTI. My dad had some work done (the common hole in the exhaust problem from what I can tell) and never got it back onto the water before he passsed away in November.
I took it out last weekend and it fired right up but then when I started trying to run it it would start breaking up and surging in power over half throttle. I took it back home and tried troubleshooting while flushing it out. Over half throttle it seems to be backfiring out the carb, I get pops and quick puffs of smoke. I was trying to feel around for leaks (both exhaust and water) and discovered a slight leak that seemed to be coming from the exhaust manifold right under the rear cylinder. Since the manifold bolts were such a joy to try to remove we decided to pull the engine out of the ski to remove and inspect.
After pulling out the engine I noticed the spring on the oil injection lever was not engaged properly and so the lever was not retuning all the way back (we may or may not have caused that trying to remove the carb. We could not quite locate any leak other than we saw small drips coming from the manifold where it connects to the rear jug but no break in the gasket.
Can anyone tell me what the minimum compression is for these engines. I did a compression test and get 130psi on each and was wondering since I now have the engine out I just go ahead try to improve compression before putting the engine back in. What would be my best option? I am guessing full top end rebuild kit.
Also after doing some research here and other places on the internet I have realized I have the old grey fuel lines (which I might as well replace at this point) and will be ordering a carb rebuild kit.
Are there any other things I should look into while I have the engine out?

) just curious on the compression and anything else that would be more beneficial to check while the engine is out of the ski.
