Thanks in advance for any advice you can give me.
Summary details:
Boat tarp leaked badly over the winter while on the trailer outside and the dumb newbie owner (me) didn't know to pull the drain plug. As a result most of the engine (up to the potentiometer (TCS) was under water for some time. In addition there was probably a layer of ice on the top as some point. The ice looks like it cracked the plastic of the TCS so I have already replaced that.
The boat will turn on just fine, but it will not go above idle speed (not limp mode). The throttle stick will put the boat in gear (forward and reverse) but there is literally zero impact of the engine rpm regardless of moving the stick. After replacing the TCS I also moved it manually and same result. Looking for ideas on what to check next.
I figure given the amount of water I took on, any of the electronics (TAC, TPS, ECM) could be faulty, but I have also read on these forums that it could also be a grounding issue. I was hoping some folks could let me know what to check first. Also, I know where the TPS and TAC modules are as they are right on top, but having trouble finding the ECM box. I see it in the illustrated parts manual, but there is no indication of where the bracket and ECM atttaches to the actual engine. Pictures welcome.
Thanks again everyone.
