I would agree with Silver Hilton. Currently my 2001 NR 19' sportster with the 175 sport jet has served me well. I have 80 hours on it have picked up some junk on the grate from time to time. All it has taken so far is to get all the speed you can, turn off the motor and the wake washes forward though the jet and up the boat and the junk comes off the suction. Granted I have not run it in any really serious weeds like at Tillamook Bay yet.
I like the layout with the windshield, top and such. I could see how you might go for an open tiller model depending on how you fish the most, it can be a little pain if you are freedrifting and always have to make the walk up to the helm to get the jet started at the end of your pass.
