Which prop is better?

Re: Which prop is better?

Youre gettin it! Lol! Yes different style props have different traits. Some have a lot of bow lift. Some have stern lift. Some have overall lift. Trust me, nobody thinks youre an idiot. I guarantee you there are a lot of folks that have been around boats all their life and think there's nothing to a set up and a prop is a prop is a prop. I been at this for over 40 years and still got a bunch to learn. We're all gonna learn by watching your progress. That's why when, way back in the begining, you asked who has the best 27" 3 blade prop and my answer was -- "I don't know. I haven't tested them all". Ain't this a blast?

Re: Which prop is better?

By gelacop,

shave your heads down or get a set of 135 heads you will increase your compression to about 165.

This is a corner-cutter...no concern is given to combustion swirl pattern, and opening the intakes require not only jet change but possibly carb change to keep any low-end torque. If I had a dime for every souped-up outboard I've passed with stock equipment, working and maximizing only set-up, I could've paid for alot of gas during my prop testing..... HP is great but efficiency is what gets the checkered flag...

Re: Which prop is better?

Kenny, The hotrod stuff I did was prior to the set-up step. It was a whole kit (different heads, reedplate, reeds, intake plate, carb jets, exhaust plate, and tuner). When I compared the new heads, they were a different casting and combustion chambers were "different". Got the stuff from a reputable yamaha performance shop. (hydro-tech). I only gained a "tad" of real world performance. Motor may now have 20-40 more hp?, but, sure can't tell it by driving the boat. I now look back at what I have done and see that I've increased in and out air flow, but, the block is the same. Just like a camshaft is the HEART of a 4stroke....I realize that I've not changed the Heart of this 2stroke. I feel I've taken a 1/2" water hose that was 10ft long...Cut it down to 2ft long and spliced 1" hose on each end. (more or less). That little 2ft section is a massive constraint. (the port timing/block). ANYWAY. I knew the next step was "set-up" to optimize what I had done. Bolting on engine parts, etc... I can do that. It's the set-up that I'm now getting a crash course in. AND, I think just like you....It's the most important part. I just thought I should get the motor where I wanted it as far as "running" and THEN work on the drive setup. Or, at least that was my thought process of "the order of things". Was that right? Things to ponder as I sit here in the rain waiting on UPS to deliver some props....lol.

Re: Which prop is better?

i dont the answer to that question myself,i started just the opposite i bought the boat used and am going with the setup first,iv already gained a bunch from when i bought it,the guy i bought it from said it was already set up to its max boy was he wrong and its still getting better.it'll all work out for you.

Re: Which prop is better?

Brownies, you need to go over to Bass Boat Central. http://bbcboards.zeroforum.com/ Plenty of guys over there to help you out on both setup, prop and the Yammie upgrades. Try the Props or Setups by Todd forums.

Re: Which prop is better?

It never hurts to get advice from more than one place. Just make sure to digest the info and make one change at a time. Dont do this and that, do this then that. Youve made great progress and have an excellent baseline. Dont lose it. Keep good records.

Dhadley · Feb 12, 2006

Re: Which prop is better?

Ron, as far as which way to start is better - that's a good question. I've always felt that maxing out what you have is the way to go. Basically you spend time more than money. But thats me. Starting with engine mods is very feesible. Especially if you know youre going to do it eventually. I dont think theres a right or wrong, just a preference. The end result should be the same.

walleyehed · Feb 12, 2006

Re: Which prop is better?

Hey guys, don't get me wrong about "working" an engine...I do it too, but some think increasing compression alone increases HP, but the flow thru those combustion chambers is more important than compression alone...All of these items must be done in balance with the rest of the engine components. Now, if a "kit" is offered for your engine...good chance it will have matching components and tell you if any block (porting) mods need to be done, and that's OK, but to say "increase compression, open intakes and go" is wrong. DH knows where I'm coming from...Brownies and Ron, I just don't want to see someone lead you in the wrong direction....I'll put my money on Dhadley anytime....He knows what will work and what won't... Hope that clears up my thoughts....

Re: Which prop is better?

Gregg, if 58.1MPH is all they get out of that Stratos rig....yes, I can walk off and leave him relatively quickly in my 18ft aluminum Deep-V that started out as basically, a stock Evinrude XP150....Yes, it has a few mods, and yes, I get some funny looks when I pass a bassboat at close range. I would not call the mods I've made as high performance mods. The speed gain, I give credit to jackplate, playing with different amounts of set-back, and testing many, many props. AND...if Dhadley wouldn't have suggested the many things he did, I would still be at 45-46MPH. Now I need Mobster Tabs to stabilize this non-pad V so it's very controlable when passing thru 55-56MPH and above.

Dhadley · Feb 13, 2006

Re: Which prop is better?

Gregg, I'm not sure why you're surprised Brownies is faster. He's turning a bigger prop about the same rpm and has a higher gear ratio. Not to mention he has a killer motor with 175 lbs compression. It better be faster!

gatorred · Feb 13, 2006

Re: Which prop is better?

I just put it on for information to use yamaha has test's for 200 having a jack plate to I use test to know what it should run when new un hopped up. what is Mobster Tabs to stabilize this non-pad V can they work on ranger too.

Re: Which prop is better?

See that Greg. The 150 had a 23" prop. The 200 had a 27" prop. Not to mention lots of stuff that makes a difference that I just scanned over real fast. (dif boat for one). BUT, that 150 is right there with me with 2" less pitch. grrrrr...... The 200 has the power to pull that 27" to where I'd sure like to be. Seems I've not added the power to pull a 27" yet...and....so far, boat isn't cooperating. Can't beleive yall (yep, I said "yall")...opps, (said "yep" also). Can't beleive yall are still here. Glad to see it though. It was 35 degrees yesterday. It's suppossed to be 38 Friday. I've got 5 props in my truck, boat is hooked up, and weatherman said 81 tomorrow. (AR weather is nuts!) I FINALLY get to spend a day testing some parts.

Re: Which prop is better?

well i know it was 50 hear in pa but snowed in newyork this last weekend just missed me my though on new boat's will they run like that are just test unit's prop's were used 3 or 4 blades mine is in canada getting fixed it 4 blade 25 pitch, like in airforce the russin's would burn a plane up just to break record mig 21 went over mach 3 it was scrap when it was done like the nascar's winston just bring the stearing wheel back ok,

Re: Which prop is better?

Good brownie were looking forward to hearing the results.you said your stratos was different which one do you have??would it be the one thats extra wide in the stern??

brownies · Feb 16, 2006

Re: Which prop is better?

It's a skeeter, not a stratos. Needed to do some work this morning. Planned on being at the lake now. Not much sense in it though. It's warm all right, and SOME KINDA WINDY...figures.... I'm gettin cabin fever so bad I can't stand it. Also getting adicted to the Olympics. I must be getting old....

Ron G · Feb 17, 2006

Re: Which prop is better?

I dont know why i was thinking it was a stratos,just shot one of my brain storms down.yea i aint been on the water in months thats about change this weekend i got a tourny so im going to have a partner in the boat to get some more numbers on my motor and hopefully catch a big sow.

Re: Which prop is better?

What do you mean you're going boating this weekend???? Do you realize Daytona is this weekend???? This is one weekend everybody has a legitimate excuse (other than weather). Kidding -- have fun guys!!

Dhadley · Feb 17, 2006

Re: Which prop is better?

Brownies, if one of those props is a Trophy keep an eye on it. They're real bad about cracking / losing a blade. When running one, if you feel anything funny -- anything -- stop and look. I suspect you'll feel a strange vibration in the floor or seat. Throwing a blade at the speed youre going wont be good.
