4-tec engine hesitation
i tried to do a search but could not find anything.
but my 155hp engine on my 03 sportster hesitates at low rpms.
but since i am here, i actually have multiple problems with my boat.
1. Today, my cousin threw in a tow line when i told him not to, and i didn't know he did until i drove over it and it sucked in and it went around my drive-shaft until it shut off my engine.
since i cleared it, maybe i am more cautious, but noticed my engine hesitates or hiccups from stop to 1/4 throttle. anyone know what is going on?
2. my tach and my speedo don't work, i even got a new tach, and that still doesn't work.
3. my bilge pump doesn't work.
4. my radio doesn't work.
I checked all the fuses. they were all fine.
any help or advice would be appreciated.

How are the clearances between your impeller and wear ring? If you sucked something into the pump you could have damaged the impeller and/or wear ring, which could cause your hesitation problem.

i will try the plugs, have to get some this week.
the rope wrapped around the drive shaft, i was able to pull of the pump housing easily enough, and did not notice any issues there.
