That's why I suspect coil vibrating in boat and not dyno, or a wiring issue in my harness maybe that we didn't see on dyno, we did not use plug we wires ignition direct to dyno, I checked voltage running at idle, no way to really check under way at WOT... Ten again I can probably wire a volt gauge to ignition for temp use and have someone watch it... Hmmm

If you've cked everything mentioned as it sounds like you have I would almost have to think its past the engine. Not a water pump or alternator seizing up or any other belt driven accessory? Again just thinking out loud.

Right I really have addressed nearly every possible thing, the coil idea just came to me yesterday, it's really seems to something that shows up when in boat not on dyno, I also dynoed with sea pump and alternator charging and engines still 1 hp apart. Like I said it's been down all last summer and all this year... Really annoying since it wasn't when I first put them in boat I saw full rpm just a few times... The rest it's always lagged over starboard
Has to be a really fukked up issue that's obviously hard to figure out... Ugh

I meant to touch on same thing earlier and then forgot. is it possible to run both engines off both battery's.
