post some pictures of the back of the boat. Did it fell like you were hopping? And at what speed? or at any speed?

relax man, I dont know about everybody else out there but I usualy have to take them out three or four times before I even get out of the marina! A cable or something always goes as soon as it gets wet.

There was a fellow over on Hot boat who has one hell of a ride . A Kachina to be exact . Ran awsome until he decided to blueprint the bottom . He gets the bottom perfect and now the thing wont stop hoping . It used to do like 86 less the laughing gas and now could only get into the 60's I think before it felt too unsafe .

Anyways , as it turns out with some video footage , the boat was actually bucking . Not your typical bow hoping but the back of the boat was the culprit bucking up and down . Went from one extreme to another with his ride plate and wedges and I still dont think he's got it figured out . He might have , I dont know . Last I remember he was putting some hook back into the bottom of the boat . Enjoy tinkering with all that wonderfull adjustable hardware . These boats are very temperamental with hardware adjustments . Good luck .

Rod,

For what it's worth, the best setup on my Mach 1 has been:

- 2.5 degrees up angle on the ride plate

- I start my run at 2 degrees down nozzle as not to sky the nose
- Once the boat has settled down I change to 2.5 degrees up angle on the nozzle

I have an adjustable diverter stop for up and down travel

The angles posted are in relation to the keel.

Hope this helps,

Very good to know info. Here's a stupid question, how do I measure the angles in relation to the keel? What tool(s)? What angle are the plates on your ride that are directly behind/on each tunnel? How do you measure the angle of the Diverter, is it also in relation to the keel?

Brad has explained how to correctly measure angles in relation to the keel.

My tunnel extension plates are parrallel with the keel, 0 degrees.

Hopefully BAE's numbers will solve alot of your problems rod . They will at least give you a great starting point .

Did you ever mees with the engine location ? Will rod even have to worry about something like that ?

-beerjet-

why? I thought it was more power, go farther forward?

Did they say Why?

Here we are 8 pages deep and what all has exactly happened as far as a project goes ?

Either read the whole thread, ignore the thread, or maybe Brad will just delete it.


Today I fixed the plumbing so that I can attach a garden hose to the engine with re-plumbing it.
I changed the main jets from 70's to 76's.
I modified the throttle cable bracket so that the cable could actually reach full throttle.
I locked out my distributer and set timing at 36 degree's.

The engine is once again snappy as **** and with the additional throttle travel... I'm sure I added at least 20 mph to the project's W.O.T. 

Did they say Why?

The most important reason was Boat Attitude, during the run and most important during shutdown.

here is my take on all of this weight distribution talk....dont take any of it as proven fact, just what little information I have gathered.....also, some input given from a very wise man who has been doing this for a long time....

it all depends on the application of the boat...

Drag Racing - you want everything back....this keeps the boat as dry as possible so you have less drag in the water. if you run it forward, its going to make the boat run wetter....thus causing more drag.

Circle Boat Racing - you want to balance it out. You dont want to run too dry or the boat will spin out in the turns. I cant go into much detail due to some top secret testing going on, but there is a sweet spot for a motor to be mounted that will help balance the boat out for circle boat racing.

Hey Rod, let me know if you need an angle finder, I could lend you mine if you need it.

Most definately.
