Boring stock SJ Nozzle

Ok, so the setup I have is a stick motor, Novi modified carbs, Riva Red pipe, Skat-Trak impeller (dont know pitch), and a pro-tec grate. I was wondering, would it be worth it for me to bore the stock nozzle? Searching just reveals mostly "depends on your boat", but I dont have any extra $$ for a new nozzle if it doesnt improve the bottom end.

Also, how far should I bore the nozzle and how much material do I need to leave to maintain structural integrity? And what tool is best for boring the nozzle? Ive got access to lots of tools, but the dremel is looking like the best bet. My only concern would be if the bore isnt uniform will it adversely effect the handling?

Honestly, the weather is just so back and forth, I can ride one day and cant the next, which leaves me hungering to do SOMETHING with my ski, even if its just tinkering. I already rigged up a new system for getting it on my trailer alone (parked on my lawn, shore has a seawall so I cant just back down), and Im probably going to rewire my bilge pump switch this week. I need summer!!!

Har har har, shoulda seen that one coming.

Is there a ride, or are we just going to party at your place? :Banane01:

Ill just have to see. If so, it will likely be after school is over, if I can get another job. I just had to cancel my trip to Savannah for St. Patty's because I couldnt afford gas and booze. I figure, if I can only do one or the other, Ill just stay here and go for booze. :biggthumpup:

You need a lathe.. A dremmel would be impossible to get it smooth and to 85mm exactally. If you don't eat a big lunch 2 doubles, and back that down to 1 double and water you will have enough cash to have it bored at a machine shop in a couple weeks.

A local shop that does head and motor work charges $20 to do it and says to come back after lunch. They will take it to what ever you want. I bored my last nozzle to 85.7mm and it lasted for years so there is still enough material for that.

About seat of the pants feel I didn't notice that much with a wet wolf cone and a bored nozzle. But I done it over winter so I didn't have a good comparrison like changing it in the middle of summer.
