650/X-2 Help!!!!!salt water ski moter

[JETSKIHORDER18]

whats the best way to get a salt water ski motor apart? All the head bolts and jug bolts are corroded in place with salt!!!!!!!

Someone correct if this wrong.l freed up an old 400 one time with a half and half mix of kerosene and diesel fuel.Soaked it for about a week.lt worked......

Spray it down and let it sit for a while. Wipe clean and use heat.

 

[ntrsspray]

diesel alone will work just fine

I was told by Art that he uses a impact wrench set VERY VERY lite . He says to just let it tap lightly a few seconds .... let it rest and tap on it some more . He said he has had good success with this method . Good luck be patient don't break any bolts .

50/50 ATF(auto trans fluid) and acetone supposedly works, set the engine upside down in a tray, fill to coat bolts and seal from air with saran wrap so the acetone does not evaporate away. Should work.... Diesel would be cheaper tho

Bump

use a torch

Thanks for all of the idea's i tried most of them, they didn't work though. So i took the bottom half of the motor apart and pulled the crank out with the pistons attached. So i guess i'll save on a gasket kit.


Thanks again

p.s. Don't buy salt water ski'sssss (fresh water only)

I like ATF (get it for free) and stir every so often.

I fabricated two 1/2" steel plates - one bolts to where the bedplate goes, and the other slides over the head studs. After the two plates are attached to the engine, I use two small bottle jacks and simply force the cylinder off of the crankcase. Works every time.

Marvel mystery oil Kicks a$$ but costs $

 

[jhall752]

soak with WD40

 

[tor*p*do]

but if i can't get the head off then what can i do?

loosen the head bolts and bump the starter with plugs in
the compression will pop off the head

To add to what another member had said.

I have had great luck using a 1/4" battery powered impact. For the most part its not strong enough to break bolts, but is enough to break them loose.

Another guy that deals with saltwater motors ALOT told me he had the best luck using a Butterfly air impact set pretty low.

It can be time consuming but surprisingly it worked very well. Much easier to just sit there and let the impact do its job than to break the bolt off and have to extract it.

30 year old liquid wrench works great hahha that is what i had to use for my head bolts

 

[extreemthrottle]

the head bolts should come off with a bit of heat from a propane torch. then soak the crap out of it with pb blaster several times, then use a lot of heat and paitence! good luck!
i have a kawi 650 motor the top end is good but the bottom end was shot. i have soaked it in the parts washer for a week and the cases will not sepperate from the cylinder no matter what i do. so i feel your pain!

 

[XJCrawler]

Spray it everyday for a week with PB blaster and it will come apart a lot easier!

i just used the diesel method in a 15 gallon tote and my crank rusted to junk!!! 1 day it looked fine but didnt loosen up, 2 day starting showing some color so i cleaned it up and inspected still no budge, didnt check it 3rd day and 4th it had LOTS of rust accumulating seemed even worse than the beginning! this was a hot rods crank which i feel are complete garbage to begin with, but i didnt expect diesel to do this! weird
