Just landed a place diverter (hydraulic setup) rudder and all. Well see what that does.

ok, Took it out today and it ran exactly as it did with the 650 double pump.
With that being said, I think its time for a timing light.
Any other suggestions? Sorry im really not a mechanic and its showing but I am learning as I go. So far nothings blown up.
I do however know alot more about a 850 dp  as for when i put it on it would not run and gas leaked everywhere. I took it apart and found the accelerator pump diaphram was busted and the carb just needed cleaned up a bit. I got lucky and had a 750 spreadbore carb here that had the 50cc diaphram in it so I used it since no-one around here stocked one.
Its just puzzling to me that the boat ran exactly as it did with the 650 on it, Im assuming the timing will be the next thing to zero in on?
4200 rpms at 53 mph gps is the best its doing.

What size jets do you guys suggest running with this carb?

I will when i can, I do not have a diverter. I have seen the hydraulic set ups but are there manual ones or do you have to do hydraulic?

Ok, with the little research I just did (Google) it seems I own the second worse flowing heads made for the 460.
With that being said Im going to do the 850 dp carb but is it all in the heads holding me back or will it still perform decent with just the carb untill I can find a set of heads?

I pulled the valve cover and saw a bunch of different things so bare with me.
*The numbers 201
*there was what looked like a "W" with a big "C" and a smaller "C" kinda inside it
* 1h8
*ford logo
*circle with the numbers 1,3,5,7,9 or a 6 around the circle.
Sorry I know I probably overkilled  it but thats what was under there

Its a weind stealth intake
No mufflers
As far as the timing, the distributer is set up like it came as far as the advance. The timing tab is not on the cover so we just set it best we could by feel and sound.
 To get it right I know we need to take the time to put timing tape on the balancer and come up with a timing tab.

Obviuosly im not a mechanic, I own a Carpet Cleaning company. Ask me about carpet, I can give you answers.

 Im just trying to get a feel for what I can expect to get from this motor/ boat.
I spoke with a supposive "legend" here locally who told me to change the cam and toss the distributer for a msd and he would "cut me a deal" by installing them for only $2500.00. I almost laughed in his face. The best part is he told me that the best I would see out of the boat after spending the 2500 would be about 55mph, lol. I hit that yesterday like it sits.

Im just looking for advice before I order something thats not going to work right.

 Another thing I keep getting is that one of the worst things I can do is put too big of a carb on it but I had an s-10 with a 355 in it with a 750 dp so im lost on why everyone around here is thinking a 750 or larger is going to be too big. I dont see how, or at least to a point.

I have a buddy who will install the cam and set everything up for around 150.00 so Im just looking to see suggestions before I break out the wallet.
What are these things capable of top speed ect. with a basically stock motor with a cam?
The guy I bought the boat from has about 15,000 just in his motor. Im not looking to go crazy like that, just basic bolt on stuff.

Thanks,
Steven

Hello everyone!
Im new to the whole jet boating thing myself and just wanted to get some advice from some of the seasoned pros on here.

 I just bought a 1969 Esquire jet boat without an engine and dropped in a 460 since that was what its set-up for.  It seems to run well but I want more!

I made the mistake of not putting a cam in it since at the point of all this I had not had it in the water yet I just wanted to make sure it floats so i went as stock as possible to keep it cheap.
 Good news it floats but its not a performer.  It ran today at about 54 miles an hour, so quick to get there but thats all it has.
I was hoping for some suggestions on a cam or other mods to get more out of it. Im only turning 4200 rpms and cant get anymore. I know that the motor came out of a service truck and had an rv cam in it which I believe to be the main problem.

So far the mods are :
bassett water injected headers
weind intake
holley 650 double pumper
hei distributer

Thanks for any suggestions on a good cam set up or anyrhing else you can help with.
Also its a berkley jet
