Now that's just a ton of knowledge!

I'll buy the blowers cheap from you...

I'd like to comment regarding my lengthy, and boring previous post.
I hope nobody takes what im saying personal. I don't mean to sound arrogant in any way, and hope I didn't come off like that. There has been a lot of help from some of the local guys here in trying to get this project to fruitition. Everyone has good intentions, and want to see this boat run like a monster. The previous owner and his brother (KVOGT), have been more than helpful in getting things straightened out. They did a truly fantastic job rigging this beauty, and kudos to them for being there to assist. Most guys would be like "sold as is" and never answer a phone call. So I don't want anyone thinking based on these posts from Dan or I, the wrong way. Like anything, a boat like this just needs some "time" to get dialed in. It has some growing pains, but is slowly become one bad ass old flat deck! |
^^^ Absolutely! Kris has been more than helpful.. not even his boat.

Steve is that your boat??
http://33outlaw.zenfolio.com/img/s9/...47835819-4.jpg If so VERY NICE buddy, the wife and I were checking it out. You must have been at lunch at the restaurant? Its a 38 Flat deck.. The oil never really smelled of fuel even when the plugs were fouled out but better safe than sorry.. not sure why its over heating, I got some good hardware in there. I can see in my strainers and one sucks all the water out of it immediately (leaner motor) while the other is about half way full, not sure what to make of that except that I enlarged the exit slits in the exhaust on that side so water is getting out faster? Water pressure is at 22psi so it probably has nothing to do with anything. We`re on the right path, getting on plane is now a breeze, drives are new, no more oil leaks, its no longer a slug, I don`t wanna sell it anymore lol ... just needs some fine tuning and some love.:daz: `m getting a good education on carbs fo sho! They were never my thing but I`ve got a good teacher :thankyouthankyou: Heres the engine vid: http://33outlaw.zenfolio.com/p13014502/e6dec698b That was us parked behind you, we were trying out the new brew pub at Reef Point, food, not so good. Geez, our boat looks like your dingy in that picture, darn camera angle! And now, bad to your regularly scheduled program on power valves! |

Alex, can I have "power valves and gauges for 300?"
So sitting here at work thinking about dans high oil temp readings. I noticed his oil temp gauges range from 100-250. All the other gauges I've seen for oil temp start at 140 and end at 300 or 320. Is it possible that he has senders for the mercury match style 140/320 gauge, when in fact he has 100-250 gauges? And if so, would that make the oil temp read high? He has big plate coolers, good water psi . I've never seen a setup build oil temp on the gauge as quickly as his do. Mine with the merc oil stats takes miles to even start showin temp. Dans are showin temp shortly after getting on plane. Wondering if his oil temp Is fine and it's just a gauge /sender mismatch? |
Also, ran into a issue once where the gauge had a bad ground. Oil temps read high. Not pegged but high. Fixed ground and all was good. Dan that's the engine that had funky things goin on with the oil psi gauge on that side?
|
Dan I disconnected a ground for a demonstration for you. Take a look what the water temp gauge in my truck does when I turn the flashers on

Video on post #1 is kinda scary, oil temp pegged, 1 point different AFR left/right bank, blower motor on Chicago gas in 12's and 13's.
Top end AFR looks good, mid-range way lean for gas around here. |

One problem solved
I took apart the oil stat and that opened at 175* right on the money so having eliminated that, step 2 and the problem:
http://33outlaw.zenfolio.com/img/s9/...88329483-4.jpg http://33outlaw.zenfolio.com/img/s10...64091744-4.jpg Gauge seems to get worse exponentially, 20* off at 160*. at 174* its 55* OFF!!!! Wrong sender? Bad gauge?? |
Check ground to gauge behind dash. Excellent progress Dan.
|
good find. I'm sleeping better now
|
Glad to see oil temp really wasn't that hot. Good detective job! There are a couple resistance ranges in temp senders. You may want to contact Auto Meter and see which one works with their gauge and measure yours. Or take shot and buy their sender and repeat your water temp test.
|
|
Dan says new correct sender installed and now gauge is reading properly.
|
Both senders are market -27 , I should have OHMed em out to see where they were at but I think the sender was correct just went bad.

Nice meeting you Dan
|
Did you run it at all yesterday Dan? There was some Cig water out there....
|
Nice meeting you too Mark!!
Mike, why yes I did, mother in law wanted to come out, I warned her that it was not the best day, came out anyway so long story short ... the inheritance probably cut in half lol http://33outlaw.zenfolio.com/img/s10...84296687-4.jpg http://33outlaw.zenfolio.com/img/s10...92455906-4.jpg |

Looked good yesterday

We did a little tuning Friday. She's just running better and better each time out. No more plug fouling, AFR's are much better, idles great, planes at 3500 easily, and running a consistant 80mph. Theres more mph in her yet. Props still too big and a bit rich yet on fuel. Engines only turning about 5200WOT, and they need some rpm. But one thing at a time!
|
Yeah what this clown said ^^^^
I had some chop under the hull and still could only pull 5200ish rpm.. the 651 cam really likes more rpm...so I figure since the props have a BBlades number on them maybe they can tell me if some more work to them could get a me a few more rpm, or that they would know what work they did.. you know, the whole reason they stamp a number on them. The guy looks up the number and tells me yeah those are 17.5 x 28..thats all the info we have on em.. ummm no **** Sherlock, thanx for all that great infomation. :picard1: |

Call Brett at BBlades he can help you out with it. I am sure he can loosing them up a bit. How much more rpm are you looking for? Maybe a shortie is in the cards for you, especially if you are boating in a lot of flat water.
|
Based on your numbers, I would suggest trying a 26p prop, this should get your RPM up to about 5600 at the same speed. The midrange will be stronger and the props will be a little easier on your drives as well. Since you seem to boat in flatter water and your boat seems to like the bow lift, I would also suggest going to an 18° rake.
The only problem with going to 26p props is I think you'll find yourself at or on the limiters (I don't know what your max RPM is) if you're running light or in faster water. Assuming your max RPM is 5800 and your slip holds true, switching to the 26p props will limit you to about 83 mph at 5800 rpm. If you think the boat has more speed in it than this, you might want to try a 27p, or even consider a 27p with a slightly smaller diameter. |
Now that you added spacers what's your propshaft height? Now that its running better and planing easy you could take spacers back out?
|
Straight bottom Cigs love high X dimensions. Here you can play around with these calculators, they helped me a ton. Love the boat keep dialing it in! Also love the avatar.
http://www.go-fast.com/boat_speed_predictions.htm http://www.go-fast.com/Prop_Slip_Calculator.htm |
Assuming you are 1.5 ear ratio and turning 28 4 blades if you can turn them 5400rpms at 14% slip you are at 82mph.
|
I`m pretty sure my ratio is 1.58, tried a few 4 blades and planning was horrible to impossible, it really only seems to like the 5 blade with alot of cupping. I`m 1.5" below hull right now, Id love to take the 2" extensions back out get that sweet rooster back but I`m not sure how she`d plane. A 1" extension would probably work perfect. Some things to try in the future.
