'99 GTX Won't Crank

I'm trying to stay optimistic about the pump, but I'm not liking the look of that one piston, and the cylinder wall in the cyl1stern video doesn't look quite right. Drop that pump, it should take you about 15 minutes.



Disconnect #20

Remove the 4 nuts that hold the pump to the pump support plate #46. Then pull back. and watch for part# 26 to possibly hit the floor and roll around.

Opps, forgot you have reverse. Disconnect #49. On the pic with the nozzle you will probably have to pull the 4 bolts tha thold the reverse bucket bracket to the exit nozzle #20

Ok, so I have GREAT news! I just removed the pump and spun the PTO round and round and round with 2 fingers, no hesitation at all! Tried to spin the impeller and it is frozen solid!!

So being new to this game, my next obvious question is what do I do next since I have taken a fair amount out to get to the starter, see pic.

1) Starter - rebuild it since it's out?
2) Pump - rebuild or buy a new one?
3)?
4)?
etc. etc.

I assume there are some requisite automatics to be done, so what would you guys do?

Incidentally, this is not the original engine. The meter does actually show 104.7 hours and this engine was put in in 2009 according to prior owner. As you can see the block is black and the head cover, fly, etc is silver. He did not know where the engine was from as he had a local marina do it. I called them but it's under new ownership since then so they had no idea. Any thoughts? I suppose it doesn't really matter, just thought it was interesting.

Thanks.

You lucky SOB, LOL. Well, bench test the starter, if it works put it back in for now and do a compression test. Fullboreonline.com paints their engines black. At the same time Seadoo painted RFI 787 black in later years it could be a seadoo engine, but there is no serial tag which I would assume means it's not factory----possibly. Sorry to make you pull the starter, but I was getting crazy with the work not happening fast enough and since you couldn't turn it by hand there really was no need to dive into the electrical. Should have pulled the pump first (although I did mention to do either), and saved all the extra work.
 
I agree. Got lucky. We all wished it was the pump, but fully expected it to be the engine.

Hey thanks for all the help! LOL, I Know, a little luck every now and then is helpful and appreciated. Was not as lucky with the 2000 GSX RFI I picked up first. It was a Sandy victim so I knew going in it was a long shot and sure enough, Fullbore is now working on that one. I pretty much got that rig for free so I'm still happy. This one though felt different and I felt sure it wasn't a Sandy ski. And I really liked the guy I got it from, a good dude; just had a good vibe, not sure why; and I definitely got a bargain.

I think pulling the starter was a good move. It was sticky and intermittent anyway, so as long as it's out, I will rebuild. All in all, even the steps of removing the exhaust, throttle body, etc was all good experience for me since I'm so new to this. Learned new and interesting ways to contort my arms!

What else should I do while it's semi apart?

You mentioned doing a compression test - can I do that with all the exhaust parts, throttle body off? Again, new and so have never done a compression test before. I guess the idea is to see if a top end rebuild might be in order?

Thanks again man! And to everyone for that matter who contributed. My tool collection is expanding at an alarming rate!
 
Ok, so I need to:

1) rebuild the starter - so I ordered an OEM brush kit
2) rebuild the pump - so I ordered a pump rebuild kit complete with bearings/seals, OEM wear ring, etc.
3) test compression - can't do until I have the starter done and put all the exhaust parts back on

Question: do I really need an arbor press or hydraulic press to do the pump? they can be a little pricey but I really want to do this myself and not send it out or take it to a dealer, even if it costs me bit more.
