Hello fellow water bike owners,
I recently came into an issue(s) on my 1995 sea doo spx with the 657x engine.
I acquired this ski in no-start condition. I did a full fuel system rebuild(carb rebuild, fuel line replacement, fuel baffle replacement) since it had a fuel issue, and it started and I took it out.
While on the water I noticed it had trouble accelerating. Eventually I had to bail off it bc I was riding too hard, and my safety switch killed it. It didn't start(and I noticed it was having trouble starting the previous times I killed it. I brought the battery home and brought it to the local auto parts store, and the tester said good, needs charging.
I replaced the 15amp fuse, but it blew again, and the battery charging coil had the correct resistance and was putting out plenty(110v+) of AC voltage and on the DC side I was only getting battery voltage(and when I accelerated it blew the fuse again, so I am replacing the rectifier. I was wondering if there is a such thing as too much ac voltage, possibly caused by the fact that there's oil in the mag housing- I will address the oil issue later in this post because I need advice on that too. Was I was right in diagnosing it as a rectifier/regulator issue?
When diagnosing the charging issue, I tested the resistance on the The battery charging coil. I removed the spark plug wire holder so i can have easier access to the mag wiring harness. When unbolting it, I broke the top left(when viewed from the front of the ski). I removed the mag cover in an attempt to try to grab that with a vise grip. in doing so, I broke the bottom bolt. I then broke the top bolt flush with the mag housing. I wanted some advise on removing these bolts. I bought a bolt extractor set, but there's no room to put a drill. I am thinking of removing the mag housing to remove these, and have access to my mag crank seal, or remove my fuel tank to have room for a drill.
I have an oil issue too as mentioned before. When I removed my mag cover there was a lot of oil. I was wondering if this would be my mag oil seal, and what would I have to do to replace that. can I do it without splitting the case, and what special tools(besides a normal seal puller) would I need?
tl;dr: oil in mag housing, mag cover bolts broke. I need help. How can I remove the bolts, and how difficult is it to remove the oil seal?
Pics attached, thanks for the advice in advance
