Answer

The first thing to do would be to remove each ignition coil one at a time, clean the cyl head mounting surface and the ground straps and reattach the coils. We are looking to ensure we have them all well grounded.

 

Then take a timing light out in the boat with you and have someone drive, running it at the point where it begins to misfire.

 

Check each plug lead one at a time looking for a cyl with erratic or intermittent spark.

 

Record the cyl(s) that seem to be misfiring and let me know what you find.

that seems quite dangerous since the only time it misfires is just about on plane at 3200 to 3500 rpms . if you get past that point it will get on plane and run fine with maybe an occasional miss up on top end . i can hardlly imagine hanging off the back of my stratos with a 10 inch jake plate trying to watch a timing light from 30 to 60 mph . can i check ohm resistance on coils , powerpack and power coil first to try to eliminate this problem?? i do not have proper tools to do power output test on these parts . i am going to check some of these tonight if i have enough light . note closest lake or source of water to access is 40 plus miles . would like to narrow down my search without makeing several trips to the water

Trim the engine enough to try to get the rpm you need to induce the problem.</p>
