First I want to thank everyone on this forum for the great information. It has helped me fix many things already on this new to me 2004 SX230. I love the boat and it is a lot of fun even after 1 time on the lake. It has a stainless scupper with replaceable flap. I am in the Dover, TN area and go out on Lake Barkley or the Cumberland River most days. Occasionally I venture over to Kentucky Lake. So here is a list of the problems I have noticed and things I have fixed already. Any advice on the things I can't figure out would be appreciated.
1. Oil in Port side airbox. This is obviously the most concerning problem. Motor seems to run fine still but obviously if I have an ECM or injector problem, that won't last long. I initially thought it was just overfilled by the previous owners marina, who had decent service records for the boat. I did a complete oil drain with the bottom plug. After pumping out oil, pulling filter and bottom plug, I turned engine over for about 5-6 seconds and more oil came out both the bottom drain and filter hole. I let this drain for about 15 minutes on each motor and then tilted front of the boat up as far as I could to drain any last oil I could. I have to assume I got it all out. I then proceeded to put the new K&N on and drain plugs with new crush washers. Put 4 quarts in each engine, which I regret. I meant to put 3.5 and then take it to the lake but somehow me and my brother both dumped to the 4 mark. After taking it out, there was more oil in the port airbox again. Starboard has none. Out on the water cold before starting it was barely on the stick, then after running 7 minutes at 7k it was above full. I then let it cool off for an hour or so and it was still above full. Later once at home on flat ground and a few hours later it is like the oil had settled somewhere and it was on the low mark again. Am I overfilled or do I have a more serious ECM or injector problem. I saw these and was wondering if anyone had tried this route, FLOW MATCHED Yamaha FX140 SX230 AR230 SR230 Waverunner Fuel Injector Set (4) | eBay I have received my YDS and will check that tonight hopefully depending on weather. I also am looking to check resistance on the injectors if I can figure out how to get to them. I have searched and found several pictures of them apart, but I can't seem to find a disassembly guide or video.

2. Port Gate cable hard to push. I read some threads on this and disassembled the throttle assembly. I removed the gate cable and the throttle freely works so the throttle cable is fine and it appears the throttle is mechanically sound. I believe the correct cable for this is Teleflex CCX63317. But I seen mention the the 18 foot for some models. Any advice before I order? While I was in there I did the electrical tape mod to keep the throttles from lowering RPM when you release. This seems to have worked great. I also made sure it was lubed good.
3. Steering. When turning starboard/right, there was a vibration in the floor. It also didn't turn near as far right it seemed. When at idle, a left turn would turn boat fairly quickly but a right turn would take over a minute to do anything really. I know this is just an adjustment issue, but they appeared lined up fairly well. Any way to measure the nozzles? Also there is 2 different nozzles, could this be the problem? I wouldn't mind going ahead and swapping the steering cables if I need to but I can't find a thread that lists the exact cables from Teleflex. The original cables from the parts book is F1C-U1470-10-00 and F0R-U1470-10-00 but I cannot verify this is correct and I can't find a length for them online.

4. Starboard RPM are lower than Port. The higher the RPM, the more difference there is. Is this the adjustment where they attach to the motor in the airbox or an adjustment on the throttle handles ? I watched a video on one of the cruise control videos about adjusting it, but it was a different model that had the throttles attached to the sidewall of the engine compartment. Mine looks completely different and am not sure which ones to adjust.
5. Drain Plug. This just doesn't look or feel right to me. It is hard to see it all in this picture but I am at work and will try to get a better picture later. The drain plug assembly appears to be installed with 4200 or 5200. I doesn't appear to have fiberglass behind it. If you grab the plug or the hole you can move the large round thing the plug goes in. I am scared to remove it to check because it isn't currently leaking. I am assuming I will have to pull it out, sand off all the silicone type stuff, use waterweld, marine tek, or something to rebuild the hull there and leave a 1/2 hole in the middle to allow a plug to go after I drill new holes for the fitting. I figure if I do this I will go ahead an put one of the aftermarket plugs that stay in when you unscrew them so I don't lose it.

There is lots more to do, but those are the most crucial at the moment to be able to enjoy some time on the water here in 3 weeks when I have a trip planned. Thanks for any advice.
Cheers!
