compression is too low and the engine will not fire most likely...

Happened to me when I first got her. 88 BR 230 OMC
Carb was all gunked up. Did you try running it without the air filter and hitting it with carb cleaner?

I have ran it without the air filter and carb is verry clean. I pulled the distributor out to check and put it back in and I think it was 180° out so I switched my spark plug wires and tried the store then I decided to change it back and correct the spark plug wires ..... and still no start.

I would suggest getting back to square 1 first...
Put nr 1 cylinder at TDC...take cap off distributor and make sure rotor is pointing to nr 1 plug wire...
While cap is off, inspect contacts...clean...? not pitted...? Look for cracks in the cap that could cause cross-fire...check the rotor for clean and not pitted contact...
Check voltage to coil hot side...
Put timing light on nr 1 wire and make sure it fires at the right time...use the light to make sure all wires are firing correctly
Change the plugs if you haven't already...
Clean carb guts...making sure gas flows freely into bowl...
Do you have new gas/good gas in your tank...? Bypass the tank and feed carb with new gas directly with a syphon hose connected to carb fuel inlet...after you've done everything else...
Compression seems low...did you have all plugs out when checking compression...? Good strong battery...? (sorry, basic question)

Make sure your plug wires are back the way they belong...without a flame arrestor cover you could fire a plug during intake and you'll get a backfire...not a good thing even though you're surrounded by water...

Yes it will turn over strong with such low compression. Healthy numbers would be around 150 and with-in 10% between all cylinders. This engine is worn out.

It will not make it run better but help prevent the chance of explosion.

To the OP, sorry for highjacking your thread. However I stand by my initial post your engine has reached end of life.

The 2.3 is the old Pinto/Mustang II engine. I owned a a few back in the day. One thing to verify is that the timing belt did not loose teeth. Set her up on TDC then remove the inspection plug on the belt cover to verify the cam cog dimple is in the right location. If not the low compression could be from a misalignment of the valve timing to crank.
