    Wont rev past 4k -ESA issue?

    Just want to give you guys an idea of why I want to enjoy this boat so much! I've spent enough hours on the boat in the driveway and just want it cruising again! I appreciate all and any ideas!

    Wont rev past 4k -ESA issue?

    That will definitely be my next step if the direct power line helps. My last idea (and I may regret it one day) is to put the esa on a switch using a relay. The esa works, so I imagine it will shift well in the water. Unplug the esa and the boat runs good through the rpm range. If I put the...

    Wont rev past 4k -ESA issue?

    My most recent thought is power from alternator. I rewired power wire from alternator to sense post, R/PU wire from ign switch (mines actually P/W for some reason) taped up, purple wire that feeds esa and my new wire bypassing resistor wire feeding coil connected at excite post. Now my charging...

    Wont rev past 4k -ESA issue?

    I did disconnect the tach ground at the tach with no change. It was easier than disconnecting at the coil since the tach ground and esa ground are crimped into the same eyelid terminal. I could cut them and crimp separate terminals on each wire to test if you think disconnecting at tach isn't a...

    Wont rev past 4k -ESA issue?

    Maybe alternator issue? It does surge past 15v @ 800-1300 rpms. Thought about wiring alternator pos to sense as I've seen mentioned in multiple posts but I have a question about that too, the coil and esa feed off the sense side. Would I move those to the excite side, then run pos to sense...

    Wont rev past 4k -ESA issue?

    88 Fourwins 205 sundowner 4.3 omc cobra 4bbl won't rev past 4k unless I unplug the esa - then it runs strong, just won't shift... 2020 when I had the motor out for transom replacement, I fitted a new cdi esa 123-9898-P since my original hadn't worked for awhile. 2022 I finally finished my...
