Hey guys and girls, how important is the rudder on your jet to have I've been told that I'm putting my family and anybody who I put in my boat endanger because I don't have a Rudder and I always felt that it was unnecessary to have it it did very little. My boat is an 18' caliber 1.
 I was told 19 ft and bigger and drop snoot you should have a rudder? Let me know what you all think. Thanks for any help

So at the Hot August nights at the Avi on Saturday a quick trip out for a little spin in my boat the boat didn't seem to be running right and sure enough I had a broken lifter spring cap so now starts the rebuild and I'm wanting to build it up to around
600 hp  or a little more so any advice and help with what to do on a budget from all your experiences as this is my first motor build in 18 years. Thank you ahead a time for any advice and help you can give me on what to do.

79 Southwind, is this a good Hull if not what would you recommend, I'm getting ready to buy another jet boat? Thank you for any feed back.
