Was wondering if anybody has ever ran into the same issue I have been having all summer. Basically, I have had my bass boat to three different mechanics that all gave it back to me unfixed. I could only give them a few weeks to investigate the problem because of tournaments, but they were not able to correctly diagnose the issue after a lot of hours put in.
What happens is my outboard will intermittently drop a bank of cylinders which is like losing half of its power. The engine will always start perfectly and actually sounds very good. After idling with half power for a various amount of time, the bank will kick on and I can get up on plane like it's a new engine. Then sometimes it looses the power and comes back on VERY quickly (almost instant). Some days are much worse than others. Also, my tach intermittently jumps around a little with the wrong readings. It might read 3000, when I know the engine is only at idle at about 1000. If watching it when my bank turns back on, it goes up about 400 rpms...thats when the tach is working properly.
Mechanics checked everything; fuel pumps, power packs, stator, spark, injectors etc. The toughest part is that this is an intermittent problem. The latest mechanic had two computers hooked up, and had trouble getting the engine to do it. Finally it lost power for them for about 20 seconds. The computer read it was the injector pulse signal to a certain bank. Nothing else showed up. He said it was the ECU, but was hesitant to commit to the repair with a $1500 part. I am stuck at this point with nobody wanting to do the repair and a broken boat. I might take a chance on the ECU if this sounds correct. I have also read something about the voltage regulator messing up a tach, but not sure if thats true. Any help with this is greatly appreciated! Brian

So that is one reason why the hosts of iboats would rather let old threads like this one sit down in the archives instead of bringing them back up where other members might try to answer the original posters question for no reason since the last time he was online here at iboats was back on November 21st, 2011 @01:14 PM.
