question for the mag pros
 

well i ran the mag yesterday,,,,all i can say is it was a ruff windy day.....Perfect for a test run. Ihave a quetion concerning my oil pressure and oil temp whats normal for my application,,,,,540 na 700 hoarse




how about it mel, you always have good info for me


Buy the way i rang a solid 78 on gps in a nice 3ft chop with the wind at my tail.....

Re: question for the mag pros

Re: question for the mag pros
 

im still rich as hell my transome was black when i got back.....Coming off plane it blubbbers and barks, i know i have room to go down

Re: question for the mag pros
 

awsome #'s....3 ft chop for that boat is nothing ...they sure do love the ruff ...

Re: question for the mag pros
 

what kind of RPM were you seeing ?
What prop are you turning ?
Just curious - Taking mine out in a few weeks .

78 mph , not bad !

Re: question for the mag pros
 

Nocig,Sounds like your off to a good start.I cant tell you a whole lot,I dont know your set up,X dimension gear ratio prop size totel advance on the dist.type of ignition your running how much trim your using how much tab you use,all makes a big diff.I had Vixen out yesterday to run chase boat for a new boat being tested here in fort myers and i ran my 15.25x16 prop with my 540 mech eng.this is my hottest set up and built almost like yours.It will turn up 6200 at 85 gps,now if i put on my 15.25x28 prop she will turn 5400 at 79 gps,so you can see props make a big diff.How does it react if you hit the throttles at 30 mph,it should set you back in the seat or you got to much prop.As far as temp.goes i run 110-120 and oil pressure 70 to80 while iam running hard and 60 when i come off plane,but thats the way I like it.

the motor is rich as hell i know i can lean way more, but i am waiting for my tuning guy to come back in to town.....The boat was bought from a propeller builder and he has a bunch of numbers stamped in the prop..



I will take a picture of the numbers if ya guys want to know pitch,

One thing i will say is holy f%(* does that boat love ruff water, you could see the speedo jump as soon as i got in 3 footers, just chewed them up.


My timing isnt quite right yet either i know i can see an honest 82-85 with more tuning

Re: question for the mag pros
 

posting at the same time mel.....


Your right pins ya in the seat from 35-40 to about 70 then it is all in the drive trim... tuning guy said the same thing....(this winter you need more oil pressure 50 pounds is hoarse sheet)

Re: question for the mag pros
 

Oh yeah my rpm has never got over 5500, but i dont think my drive was up enough, i am still getting use to this crazy bastard.......WOOOOOOOOOOOW what a ride

Re: question for the mag pros
 

Nocig,sounds like your having fun now.My props are both Bravo 1 four blade lab finnished,i had a hydro motive 15.5ox26 and wouldnt work at all and got rid of it.I only ever run one race with my 540 that was in 2002 in P4 and got a DQ and went back to the 502 an 509 engines in Vixen.I know 80-90 is a real rush in open boat,but things can happen so fast,and you cant do anything but ride it out.Have fun but keep it safe.I guess i sound like a old woman but i been their and i know that feeling when seconds seem like hours and your on your own. Mel

Re: question for the mag pros
 

Nocig,one more thing.With them fuel tanks in the back,dont get wild with the trim or you get a surprise you dont want. Mel

Re: question for the mag pros
 

Mel i feel like your a second father to me........

I have been careful thus far......

I am spinning a 3 blade cleaver

Heres the numbers i have no idea what they mean

moa 15 1/2 x 25

whs 684

vo22

WHAT DOES ALL THIS MEAN

Re: question for the mag pros
 

Nocig,Sorry about that,but i would feel awful if anything went wrong after i went and said go with the biggest engine you can.Enough said about that,just dont forget some of the pointers i gave you.Now that prop is a 15an half diameter by 25 pitch,that was about right back when they used those drives but i would try a 15.25x26 bravo 1 4blade if i could borrow one from someone,in my book the 3 blade is outdated for your boat an power.I tried one on Vixen and didnt work anything like a 4 blade. Mel

Re: question for the mag pros
 

thanks again mel im going to look for a prop this weekend....Iwill let ya guys know

Thought this was a good tread name to use. These are a dummy set of Lighting Headers to try for fit in my Sport. They are about 1/2" too wide at the elbows and do not clear the outside rim of the hatch opening. The engine hatch is about 3/4" thick there too and angles in a little, so they just do not fit. Any other manuf. that you guy's have had luck with that fit? I have Sm. Blk.s 450hp with pretty big cam. It would be great if the elbows would fit down under the hatch too... I guess this is why they made the Starfire. ... any help would be great...

i would try stainless marine gen 11......They are a lot more narrow in the body....Plus they can due anything with your tail pipes......Give them a call and ask for brownie....

No Cig,did you ever get that new 540 in the water yet to see how she runs?I just got finished with Vixen,changed controles,new carpet,new seat bases,new exh.gaskets and a good tune up.Last time we were out she didnt seem like her old self,when dave started giving me a hard time with his Phantom i knew somthing wasnt right,and she idled like s--t too.Found the hold down bolt had gotten loose ,was running 28 totel instead of 38.Man is he in for a surprise on the next outting.If i could figure out how to post pics on this thing now id be all set. Mel

Nocig you are right, I called Eddie, Imco and Stainless today, Stainless has the most narrow manifold and a low elbow height too. Thanks to the great advise from Jan at Lightning Headers I am only out the shipping cost to trial fit a dummy set. I had no idea that option existed, wow was it worth it. I would be cutting into my Mag and making hatch mod's too if I would have just ordered the custom pipes based on transom measurements. Its too bad they don't fit, tubular headers would have looked great.

tudular headers will look grat but the just done last like stainless marine....It will be the last set you buy, plus the gen 111 make more power on the dyno than any tubulars..

today is the day. sometime after lunch will post video

Do you know anything about how IMCO performs or Eddie Marine ? I hear Stainless is a 2pc casting, but what is the Generation III? I looked at their website but must have missed the Gen III... I guess I can get an S pipe from them dry to the transom...

Good Luck on that run today, I am on my back in the half cabin wiring.

Ok, another question... I have the Throttle/Shifter Controls, but I am missing the parts to connect the cable up into the socket. I need to your ideas on how to get the parts ?? or fab somthing up that will work ???????
Here are two pictures of the Socket.
