    Default need help with the second coming

    Hey guys, I am new to the forum, I have a 73 Kona jet that was my pride and joy about 15 years ago. I was given it back in 1994, my Dad was the original owner and I took it on until I had my first son in 2002. We ended up getting a family boat (wake boarding boat) and the old Kona got locked up in our rental house garage ever since. My father just past in January and after saying I was going to get the boat running again for 2 years, I have decided to break the dust off of it. When I last used it the motor was running great, but after that length of rest, I will have to go over it again.

    My concern is the pump, I added a place diverter on it way back when, but I did not do much else to the pump other than adding a intake grate, I want to get more out of it, I am not sure if I will need to do any tear down on it after it had been sitting so long. In 98 I found an old Wreitd that was sitting in someones front yard for 10 years uncovered and restored it for my brother, on that Berkeley I got luck and all I had to do is take it apart, free it up and lube it and it was fine.

    What if anything should I do first? What can I do to it for more speed, will a stainless impeller make a lot of difference and is it worth the $1200?

    I got the engine covered, it's just the pump I will need help with, any tips would be great.

    thanks

    I would reach out to Jet Boat Performance in socal. They are a WEALTH of knowledge and can hook you up with a rebuild kit, or do work for you. Another option is Bergeron Marine in Mesa, AZ. They just rebuilt my old Jacuzzi jet and did a fantastic job....was able to use the original impeller after a blueprint. I know they are both a ways from you, but might be able to send you the parts/guide you with the install (if the "central valley" you are referring to in your avatar is in Norcal....(I grew up in Redding). Another option I have heard of is Jack at MPD (again in so cal I believe). IF I'm correct about your locale, after reading your message I called Phil's Prop shop in Redding (he and my dad were good friends) on the hope they did jets too, but they dont....said if you want someone in Redding, to possibly try the sea-doo place (yamaha??)... supposedly there is a guy next door/nearby that does the big boat jets... Hope that helps!

    With a stainless you set the tolerances tighter= more performance, But heavier...more power to spin it, But you can turn them down, like any impeller to get insink with your engine.........call JR Davis 1-530-1450..he is in Oroville

    Congratulations on getting the Classic back in the water , It sound like the boat is pretty much ready to go back in the water sans fluid changes (including fresh fuel ) You didn't mention Horse power but assuming its relatively stock or a mild build , theres little to no advantage to you by adding a Stainless impeller (over aluminum) , freshening up the jet with a base overhaul and reseal couldn't hurt after setting for years . Get that Hot Rod out of "moth balls" , drive and enjoy it You'll honor your Pops in the process , the overall performance of the boat will tell you a lot (rpms vs speed and performance) Best of luck ! Tom
