1987 Ski Nautique Won't Start

[Pete87nautique]

I have a 1987 I bought in 1988 with only 65 hours. today have 870 hours It has started every spring. Normal maintenance.
3 weeks ago we were cruising around, medium speed and, my boat just stalled. I have not been able to get it started since.
Here is a list of what I have done/replaced
New ,
Starter
Carbuerator
Fuel pump
fuel filter
3times, added an inline fuel filter
coil
drained all the fuel
new plugs 2 times
Compression test. all cylinders good
fuel gauge and sender
changed cap, and rotor, points, condenser(spring)
Fuel gauge and sender
HELP!

Take a spark plug out make sure it touches ground and start the engine you see sparks.
Don't touch the engine or spark plug during the test.
Also check the spark plug is it wet?
