Motor Replacement 96 GTX 787

I am getting ready to pull the motor out of my 96 GTX (787). I bought it cheap from a buddy of mine, motor was locked up, it sat for two years, we got the motor loose but it had water in the crank shaft housing and one of the pistons scrub at one point. Also runs at low compression and only if I hold the start button down. I am going to send the motor to the Seadoo Engine Shop in Horsham PA, since I only live about 2 hours from there. ( Does anyone have reviews on this place ? I spoke with the guy and he seems very knowledgeable ) Is there anything I should know about pulling the motor out ? The motor is only about 5 years old and only had about 6 hours on it. The guy did not use it or take care of it very much.

Also I have done research on putting it back in, is the alignment tool necessary ? It sounds like it is, and I have no problem getting the tool. Also I plan on flushing all the lines and replacing all of the filters on the ski, is there anything else I should clean or re-build while I have it all apart ? I already plan on flushing all the lines and tanks for fuel and oil and my buddy said about cleaning or rebuilding the carbs.

Is there any process for checking the oil pump ? Should I just replace it anyways to be on the safe side ? I want to put this ski in the water and not really worry about it. I will replace what it may need. I got the ski cheap and do not mind putting the money into it as long as it doesn't cost more than a new ski.

Me and my buddy are very mechanically inclined and we should have no problem doing this as long as well have all the info we need. I have the shop manuals and have been doing as much research as necessary but its always good to hear from experienced people, you get better info that way sometimes.
 
The reviews on SES, SeaDoo Engine Shop have been generally favorable, the negative that I've heard is they have a very long turn around time.

Here's a thread you might want to take a look at.

check your motor mounts while engine is out, get a good look at your magneto, make sure it looks good, i'd also check all the exhaust hoses, thru hull fittings, etc, make sure no issues are there, easy to replace when engine is in the shop. maybe pull the ebox and inspect the inside, inspect and repair vts if needed, consider cleaning all connectors and adding the dialectic grease but don't go overboard. maybe replace your exhaust coupler (pipe to waterbox, get from napa) inspect the pipe VERY carefully for pinholes, even consider blasting it clean then inspecting. of course, pull carbs, inspect/rebuild/replace as needed. see if the waterbox is rusty inside (pull it, shake it, see what comes out) pull pump and at bare minimum replace oil, but i'd like to see you inspect bearings/prop, check for other obvious stuff, straight driveline, good bearing seal...

drain the gas tank and give it a good cleaning, no better time than now to pull that, empty, rinse it real good and get any gunk out.

and re: SES,, yes, as far as workmanship, the reviews seem to say they do quality work, as far as turn around and shipping issues. well, that's another story, they seem to be working on improving that :)
 
Thanks for the info,

@ Tater salad - Who is Doc Honda ? Never heard of it ? If I have not under that name.
 
Being that you are local to SES and he knows you are close...I would think he will be your best bet. I dont think Tony does engine rebuilds but I could be wrong.

SES has quite a checkered past but none of it was really questioning his work. Mostly looseing motors in shipping and taking forever.
 
SES has a guaranteed ship date or free, so there should be no issues there. I just got my motor back from SES and installed in a 96 GTX as well. This is the link to the build it will show most of the steps I went through with the same ski. http://www.seadooforum.com/showthread.php?59056-96-GTX-Rescue&highlight=

Here is the link to how it went with SES http://www.seadooforum.com/showthread.php?59242-SES-Rebuild-Status&highlight=

If your not to fussy with how it is painted get him to paint it for you, if you want to do a quality job yourself then ask him to just make it paint ready for you and paint it yourself.

When the motor is out, re-tap all the mounts so they can be torqued down properly, also I re-tapped all exhaust and mounting threads on the motor when it came back cause they were full of paint.

Get the alignment tool, mine was way off, 3/8"

The oil pump should be fine, they rarely fail. Usually it is a plugged filter or broken/cracked oil lines that breakdown in the oil injection system.

If the gas gauge is not working, it would be a good time to fix that while the tank is out.

Pull Rave valves and clean/replace parts as needed.

you being in pittsburgh, i would just let ole cousin doc honda overhaul it


Dr Honda sure he would do the job, except it would cost you more, but what i was talkin about, you 2 live in same county, he has a business there, http://www.a-lmotorsports.com/ and he could put your new motor in, align it properly, overhaul your carbs, check, service, and/or rebuild you jet pump assy, replace wear ring if needed, set it all up (PROPERLY) but, it will cost ya !!! but, it would be safe to say, it would be done properly ....
