It was so nice to get back out on the river .. Thanks again guys I needed that and it was fun ..Glad we went to Chisholm trail , water was nice there except for the mud .. .. I though I was not going to be able to make a run when the throttle cable came loose from the foot pedal and I did not have the tools needed to take the foot pedal apart .. Luckily some southern engineering I was able to get it apart and back together .. I needed to unload and load the boat twice anyway for practice ..
I was determine to get on the river and came find you guys ..
It was a fun day and yes the boat did great .. I did a little tuning this morning on the engine and adjusted the plates up a little more and maybe next time it will be a little faster .. one more degree of timing so we are up to 33* now ,, That is what she liked on the dyno .. Plugs are pretty black like the pipes , so I could lean it down some but will wait for a while on that . let see how it runs with the plates adjustment and 1 more degree of timing ..
1st pass was 102 at 6400 RPM and second pass was 107 at ?? RPM about a 100o foot passes .. The boat felt very good .. I got rid of the nerves after a few little test burn outs .. Thank God ..The engine sounded awesome
Wayne I should have gave you my cell phone for you to Video it , my little video camera was all over the place ..
I am HAPPY to be back playing .. Can't wait until we go back .. Thanks for the pictures Wayne

Wow, I watched the entire video, got drunk and fell out of my chair watching and I have not had a beer or Crown Royal in 2 months! ......... ha ha.....
Boat looked more impressive from where I was...... looked and sounded really good. Now the fine tune fun begins.
I really liked the river up where we were. Just to many roll bar ski boats in the way.

I tried to warn you .. Next time I will see if you can video the boat for me .. Free drunk .. Ha ha ..
The boat sounded good, but now I need my Dramamine Motion Sickness Medicine.
You did put out a warning though, so I entered at my own risk.
It did add a whole new dimension to the boat ride though.
Seriously, the boat sounded great and the RPM snapped right up there, no hesitation at all.
So what do you think about the gearing as it is?
Can you notice a difference in the way it ran, from before?
Sorry I didn't make it.

Not sure Jim .. I want to tune on it a little and get the plate set first before I think about a gear change .I think it will pull the 32's just fine . It has a lot of power .. I just need to air it out a little to see what she will do .I am hoping to get it to run up around 7000 or 7200 RPM . I was taking baby step yesterday . I had to get rid of my nerves from the driveshaft problem .. You would be proud Jim , I broke out my Lifeline jacket and wore it yesterday .. I had my helmet in the truck but with the problem I had with the throttle cable , I forgot to load the helmet in the boat .. Oh well - At least I did the good jacket ..
Water was good the at Chilsom trail

Thanks for wearing the Big Boys jacket. I'm glad to hear.
Once you get used to the good jacket, the others will feel like water wings and you will wonder what you were thinking.
You had mentioned in the earlier post the plugs and headers were dark and you thought about leaning it down.
I'm certainly not an expert tuner, but I'd move very cautious doing that.
Unless you make a hard pass and basically cut the engine and check the plugs where you are or get towed back in, you cannot get a valid reading.
When you idle back in, you're running on the idle feed mixture and not the main jets. Almost any idling will wipe out the actual reading you're looking for.
Talk to EO or someone who really knows, but that is my understanding.
Can you download your tach playback or print it?
On the flash, you can get an idea if making it richer or leaner helps.
I'm glad you were able to get some runs in, I'm hoping to get mine in the water soon.
From my experience, each run you make, you'll still be thinking about the noise for a while.
It gets better with time.

I am not going to touch the jetting yet .. I added the 1 degree of timing yesterday to bring it up tp 33 like we had on the dyno , or I may go back and set it back at 32 again and see what she does with just a plates setting . .. I will run it again and see what she will do .. I prefer to have it a little fat .. I know about having to shut it off and check the plugs , I can do that and then just change the one plug that is easy to get to and then cruise back in while on the water ..
I am taking baby steps this year , so no big changes ..
Added a little timing yesterday and up the plates another 1/2 turn and we will test again .. It may be a few weeks before I go back out .. I have a small oil leak at the back of the engine I need to look at , very small , maybe pan is leaking a little or an oil line ..
The plugs were all pretty black and I could not get a timing line on any of them . Pump gas is going to be hard to read ..
Galen it may be 2 week before I get back out and then for sure in 3 weeks ..Let me know if you send the O2 sensor down

Good morning Billy,
For what its worth here's my $.02 on tuning pump gas.
If you are tuned for max power the plugs will read like normal, porcelain chalky white, metal ring dark gray (however I tend to leave mine almost black), and coloring down about 1-1.5 threads (I'm only at 1 or just past). Your collectors will always look flat black, you'll have to pull a header and look at the primaries to see better coloring. My plugs might read like that because even though mine runs slightly better with 37* I just run 36* for safety margin since pump gas varies with winter and summer blends. I also don't tend to watch things quite as close at the lake playing as I do at the races.
If your engine was mine I'd look at the actual observed dyno numbers with the air density at the time of the run and where they had timing and jetting and then figure the air density you were running this last weekend. Like Jim said if your carb isn't dialed in you can't read plugs if you run any time at all after a WOT pass. Galen's offer of the wide band o2 set up would be an excellent deal. That way you can see what is going on and adjust accordingly. I'm betting being it was dynoed and the way it sounds its close at WOT but it probably needs IFR or idle airbleed work on the idle circuits and maybe power valve or PV channel sizing.
Take your time and enjoy you're on to the fun part now. clap.gif

Thanks I will be going slow , no big changes at all will be made .. Right now with the 6400 rpm and 102 mph I am at 20 % prop slip .. So I need that to get better also .. So will try and go back out with my plates adjusted some and see what she will do then before I make any changes to the engine .I will wait until Galen send me the O2 set up and then get some good readings before I change the engine settings .
Trust me , I am not going to make any changes that will hurt this engine .. BABY Steps ..

i might be in for something in October.

You indicated you raised your plates 1/2 turn. Thats' a fairly large change.
Usually 1 or maybe 2 flats is a noticeable amount.
If I recall, you have 1/2 inch turnbuckles, and a 1/2 turn will raise or lower the plate .050 of an inch. ( I think )
I don't know how you were running it, but unless you're standing on the up peddle, you can't tell what's happening.
If you're even touching the down peddle, that's the same as 2, 3, 4 or more flats on the plate.
Depending on how you're springs are set and the overall boat set-up, even when your foot is off the down peddle, the plates could be sucking down.

Boat is running wet , could not see the skag at all . Foot was off the down pedal ..I can always go back and adjust them down if it is too loose . I got to get this boat freed up some .. Yes I know 1/2 turn up is a lot at one time .. OK - maybe I go back and adjust them down 1/4 turn
Maybe it is time to send this boat somewhere and have someone dial it in for me and I just drive the dam thing..

FWIW, I never run plates more than 1/4" up, if you need that much up should try moving the prop under the boat farther or try a different prop. Believe it or not a nickel or two in the coupler between the v-drive output shaft and the propshaft will make a difference on a boat that's close. As a general rule I start with plates 1/8" up and depending how it runs/looks usually move the prop from there.
Good luck.

Loren- that is my problem . The prop is about 1/8 inch from the strut , can not move it under the boat any more unless I cut the strut . May be time to buy a prop and try that .. A couple years ago i had it running with about half the skag out of the water .. So i just to get back to that setting .. Not sure what changed . Everything else in the boat is the same . Engine at 36 inch , v drive at 96 inches .. I have not moved the prop or anything .. Just added new cavitation rods this past winter .. I have tried the nickles before and right now I do not have any in the coupler ..
Maybe start completely over on the plates .. I adjusted them up 1/4 in for the first run when I broke the drive shaft , then I went up 1/2 turn , maybe 1/2 so that would be 3/4 inch up and it was still wet Saturday according to Wayne ..
I am going to pull it back out and try setting them again this weekend .. *ucking boat is pissing me off .

Brazos River Rat ( Billy ) said:
Billy how much power have you added between when half the skag was showing and now?
Power and prop rpm tend to lift the tail which in turn will roll the nose down. It's all a balancing act with these flats. Have you changes props, even though they are stamped the same they may act different on the boat. My old 11x16 is a prime example, it likes to lift the tail and you can't get it far enough under the boat now to make the boat ride how it should. Dallas at Menkens can bore that hub deeper and cut it back so the prop sits farther under the boat, I had to send my new 11-1/8x16 back to him and have him do that.
Just some stuff to ponder think.gif
