Bought a trailer, came with a free gtx

[Used or rebuilt]

I bought a single place trailer for $250 and it came with a 1996 GTX 787. From what I was told about it is the seller bought it from a friend and never did anything with it. The friend never had it running and his friend bought it from a lady who had a bunch of work done to it at the dealer before she sold it. The work done was unknown but it should run. What I have discovered is there is no dess key and the starter is junk. I pulled the drive apart and everything there looks good. It is complete minus the key. I made a tool to turn the pto with a drill to do a compression test and was impressed with the numbers. With the lack of knowledge from the seller I'm concerned with weather it was winterized. Is there a simple way to test for that in the boat or key areas I should inspect? Anything else that could be checked out before buying parts? If the engine itself is good I'd get it going otherwise I'll just sell it to someone to part out.

This is my first rotax and I know nothing about the rotary valve and what if anything I should check there.

You aren't going to be able to test the compression without a starter. Without knowing the compression it really isn't going be possible to know if the engine has potential.

There is no bypass for the DESS.

I have already compression tested it turning the prop shaft with a drill. 160 on both cylinders.

My main concern now is if it wase froze not being properly winterized.

That must be one heck of a drill.

It is possible. You could try pulling the head to inspect.

Brushless Milwaukee has plenty of torque for that job.
What's typically the first thing to crack in a freeze?

The outer cylinder castings.

the only way to bypass the DESS system is to replace the MPEM with an aftermarket one.
