Hi everybody!
I recently installed a Holley terminator fuel injection system on my 98 Baja. I am looking for some help dialing in the numbers and adjustments on the system as I can't seem to figure it out.
Background on the engine, it was a 200 hour boat but about a year ago I had the engine gone through and upgraded. Sitting around 500+ HP. 10 on the compression.

-Last experience with the boat is that is started perfect and ran perfect in the driveway.
-From trailer to docking it started/idled perfect.
-Restarting once leaving dock 5 min later was slightly worse than that of the on land and first water start.
-idle to out of wake zone went fine
-Engine bogged down as soon as I tried to advance the throttle
-After trying to advance it 3 times it died.
-Didnt want to restart for about 15 min.
-Seems like it was flooded but took throttle to restart.

Thanks for any help,
Sam

Well, there's the problem... You should have installed it on the engine, not the boat...

(That's a hint, we need to know about the engine not the boat. For all we know you have a Caterpillar 3524B in there.)

Nice theoretical thing about this system is that it should be easy to tune. What was the magic box telling you about your mixture?
