so im having trouble getting my boat to plane i was reading the manual for the triggers specs and says that the resistance on the coils is from 1200-1350 ohms so my reading on my trigger are frome white-black to brown is 1300, and white to purple is 2500 so it means is bad? also taking a visual look at the trigger looks that the plastic that covers the coils is cracked and bumpy like an expanded capacitor i just want to make sure is bad so i can order it pleas help thanks

Check out outboardignition.com They have trouble shooting PDFs of each engine.

The specs from OI.com is usually for their products.
CDI ignition is another p​lace that has procedures for testing.
If at all possible get the Mercury specs.

A higher reading doesn't usually mean it's bad.
An "open" reading is what I'd worry about.

Do a spark check after a compression test.

IF??? You have good comp and spark.
Then I'd look elsewhere f​or the problem.
Start with the fuel pump and then filters.
Check the hose for soft/ mushy spots.
Then check the connectors.
Is the linkage opening the carbs correctly?

I think the 95 had a filter between the carb and the pump.
Replace or clean.

Check for water in the fuel?
