Where to buy engine parts?

[deanler]

Well I'm a serious n00b to the sea-doo world, I just baught a 93 650xp 2 days ago with low compression in one cylinder (50psi) for 500 bucks with a trailer so I'm looking for a little advice on where to buy the best and cheapest engine parts.

Also if theres anything I should be checking or replacing while the motors out? I have sleds atvs and bikes but I had never even seen under the hood of a seadoo until I baught this thing so It's going to be a learning curve

I notice this sbt place has a whole engine for like 650 bucks but I've also already read some questionable reviews about them. Just need to know where I can get some good pistons at a good price and if theres any I should steer clear from.


Thanks In Advance

i'd pull the cylinder, and re-ring it, if sleeve and piston are good. Maybe need new piston, but having 50psi, think you can save it.

Thanks for the link, that is a good deal but I'm going to need cylinders and a bunch of sh*t went through the rotary valve so im pretty sure those faces will need machined..

If I buy that kit for 429 have the jugs bored for 50 each Im at 550 already and then I need to figure out what to do with the rotary valves..

SBT motor is looking pretty good right now but still a little on the fence with there reputation

 

[seadooya]

whats up with the rotory valve? That can be replaced, or is it the surfacer on the motor? If surface on the cover, that can be replaced as weel, for 25 buks.

 

[deanler]

The surface on the crank cases is badly pitted aswell as the intake side of the cover.. Im under the impression the cases would need to be machined to clean up with scoring?

Thanks again for your help

 

[seadooya]

pitted is ok, just gives more surface for oil to pocket up in. If the "cover" is damaged, meaning scar marks going from port to port, then that needs replaced.

SBT has a very good reputation. In the past 5 years of buying their motors and other parts, I've never blown one. I've had a bad RAVE valve.

There is a trick to buying their motors that is also the cause of why they get the bad rap from people. I can't tell you how many times I've heard/seen someone buy one of SBT's engines and install it, only to have it blow up on them. The reason? When they blew their first engine, they only replaced it. They did not take the time to find the "Root Cause" of why the first one blew. The only thing SBT gives you is the motor, your carbs, oil injection, rotary plate, pickup/magneto are all the parts (amongst a few more) that can be the root cause of why the first motor bit the bullet.

It's so easy to see the "results" of what happened, but so hard to find out "why"... It's really pointless to put together a new motor, not knowing why the other blew.

The other reason I've seen SBT get bashed, is other mechanics. It seems SBT's prices are so low, that all the mechanics shops that do this regularly are starting to see their profits fade. SBT is like the Walmart of motors.

If you read their home page, you'll come across a sectiont that states all the tests they put these engines through. These tests are designed to test the integrity of the motor. If they sell you a motor that doesn't meet OEM specs, then they know they could be sued. Of course, they make that kind of hard when you have to agree to mediation before your allowed to purchase one of their motors.....

Anything you buy has a chance of error. One in 100 motors can have a defective part that got by, they are only human.

So, as you can see, I'm a supporter of the SBT engines. I've had great luck and many of my customers are happy. It's a good substitute for a quick, low cost motor if you don't have the funds to rebuild your own.....:cheers:

Thanks seadoosnipe, thats re-assuring since I ordered a top-end kit from sbt along with carb rebuild kits and some other misc. gaskets this morning. I'm in complete aggreeance with you that if your not going to find the cause of the problem there's no point in even rebuilding it. With this one im not 100% sure what the cause would of been since I am new to sea-doos but I'm guessing with the bearings toasted right out of the rods it was an oil problem and the previous owner did admit to using cheap walmart oil in it. I'll be going through the carbs and testing the oil system to make sure everything is up to spec along with changing out all the lines filters ect.
