Frustration with 2001 Evinrude 115 Ficht

I bought an Evinrude 115 Ficht engine in the fall of 2001. Since the first day I bought it, it has always had problems with the engine missing, especially at higher rpm. I have had it back to two mechanics under warranty and the following has been done:<br />1. uploaded new software<br />2. new fuel pump<br />3. new vapour separator & lift pump<br />4. new prop<br />5. new spark plugs<br />None of these has solved the problem. The best way to describe the problem is that it seems like I am dragging a bait bucket. I feel slight hesitations as does everyone who rides with me.<br />People on shore always comment "what is wrong with your motor?" It apparently makes regular pops when someone on shore is listening.<br />Finally - this problem is subtle enough that it only happens at the higher rpm. It starts great and jumps out of the hole perfectly.<br />Is this electrical or fuel related? Any help would be greatly appreciated.<br />Peter

A couple of things come to mind. Make sure the prop allows the motor to turn up to around 5800 rpm. Have your tech set the crank position sensor to around .030", not the wider gap listed in the manual, and reset the timing using the diagnostic software.<br /><br />Also to rule out a problem with the fuel supply by running the motor at all speeds with a fuel pressure gauge installed on the test fitting on the fuel rail.

Thanks for the information. I had one tech tell me to try a 15 pitch prop which caused the motor to over-rev to 6000+ rpm. Another tech. saw this as a problem and sold me a 19 pitch stainless prop. The rpm now only gets to 5300 but with a speed of 50 mph.<br />Bombardier has been good about doing all this under warranty but I am so frustrated with nobody solving the problem. It is not fun going for a boat ride with this. I am so far from help that it is a 6hr turnaround for me to take the boat in. They try to fix it and still it has the annoying irregular rhythm.<br />Peter

Sounds like you need a 17" prop to get it in the proper rpm range.<br /><br />The motor will never run right until it's set up properly.
