Ok I have a 1997 Evenrude 130hp 90 degree looper,and only the two upper cylinder are firing, I checked spark right at the lower coils and they were dead, also I found that the right bank , and I assume the right bank is the one , if I'm behind the boat , looking to the motor, so the right bank has a higher temperature than the left bank, actually very hot , but still I can touch it, and the water takes to long to start pissing out of the motor, like 30sec , or faster if I accelerate the motor, I just changed the impeller, I also pulled the thermostats and after applying some heat with a lighter they seams to work fine, compression is fine..any sugestion..will this be the power pack, the stator, temp sensors or, time base..thanks
