I can see how easy it would be for that to happen because the pump handles are very similar looking. I always take a second look at those things. I would have thought that you would have to drain the tank but I guess depending on how much was added may be not. In this case low power would be expected since diesel has at have 2x the comp. ratio to ignite.
Gas in a diesel on the other hand would be very bad.

Mark T, Any updates since you got the low pressure fuel pump put in?

(Other than the diesel issue) your low power at high rpm issue sounds very similar to what I am experiencing right now.

Thanks,

Got my new low pressure fuel pump in, engine sounds fine, but now won't go in reverse. ( I did get tangled up in a chain link fence, last time the boat was working, it was hidden underwater ) boat will engage and go forward. Wondered if it may be the prop hub ? as opposed to a transmission issue. Any thoughts, Its a King Cobra OMC sterndrive, vintage 1994. I swapped out the stainless prop for the aluminum spare and now it goes in reverse ?? go figure. The stainless prop has a Guardian hub kit and the shoulders are definitely smoothed off. Not sure why it would go forward and not backward ?? but at least it works now and I have a couple more guardian hubs on order.

Glad I tried, no telling how much it would have cost to take boat out of water and run tests.

Mark T, did you hit WOT with no issues since the pump replacement?

Glad to hear you worked out the reverse issues.

Also, if I were to have fuel pump issues, would it pull up a code?
