I bought a 97 Triton tr17 with a 1997 Mercury 115 ELPTO (serial number: 0G52****) motor on it about a month ago and I'm having an issue where it doesn't want to rev up over 2500 RPMs. It doesn't shake or anything once it reaches 2500rpm and it idles good so I think it's just running on the top 2 idle cylinders and never switches over to run on all 4. So far I have checked compression, all fuel lines and fuel pickup, spark on all 4 cylinders, rebuilt fuel pump, replaced inline fuel filter, checked that all butterfly valves on carbs were fully opening and closing, & checked that gas was getting to all carburetors.
I noticed on it earlier that there was one purple wire and two blue wires one coming from a module at the bottom right side of the motor that were unplugged. Looking at a service manual to a similar model motor (the 1997 jet drive one, mine has a prop) I think it may be to the rev limiter or the oil safety system. I also noticed that when I turn the key on there is no beep from the safety system like the manual says should happen. Could my problem be that it is going into limp mode or something because of the oil safety system or rev limiter not being hooked up right? I couldn't find anything about such a mode in the manual. Also does anyone know where I can get the factory manual for this motor for a reasonable price? I haven't had any luck searching Google as they all seem to be for the jet drive model.
Any insight would be appreciated. Thanks
