When I stab it she will hit 6 grand and stay at 6000-6500 till I let off . I will try and post a video of it and you can let me know what you think I should do so I don't waste any time and money. Will post this afternoon.
All you said in your first post was that it was a 502. What kind? Stock GM with hydraulic roller cam or?? If it's the stock GM one it may not have enough valve spring to really spin anymore. I personally wouldn't take it above 6000rpm if it's the stock deal.
Jim,you might try 707 864 0332. Joe Shelfo,for a prop,he is in Napa.good luck
Hey Jim did you ever open the v-drive to see what gears are in it. The boat sure does look alot different from when i sold it to you . Good job.
Bob
Thanks bob.. Been having a lot of fun with it. Way different than driving a Jet.. This takes a little skill to drive.. Makes it interesting thats for sure.
I would start with the plate adjustment. and then start trying other props. The plates may improve the pull, but I would venture to guess that that you are trying to blow the prop off the boat (cavitating) and when it tries to hook up you are going for a ride. I would go for a little more diameter, like a 11.25 or 11.5 x 15. I wouldn't mess with gears until the boat handles properly. Call me if you want to talk about a baseline plate setup...I don't want to type that much.
Just got off the river with a 11 1/2 x 17. Didn't pull as hard but got more speed. Don't know how much more. put it didn't impress me. WIll be trying another one tomorrow hopefully. What was funny is that I pulled a little less rpm then the 10 3/4 x 15 prop. WTF?

Like I asked in an earlier post what type of 502, stock? What cam? If it only pulled a little less rpm with that prop change maybe your engine doesn't make power any higher with the current configuration.
Sounds very fun, I am about to mount my bbc in my 68 Hondo, I'm very interested in your setup. Motor position, v drive position, prop position. I believe I have all the stock settings however I'm running @700 hp. I was thinking of moving the motor forward a little. I have a 11 1/4 x 15 that has been recommended for the boat. daddy b
