"Wanted" 29-30 pitch prop

[Reed]

Something doesn't make any sense....

A 23P at 9500 RMP with a speed of 58MPH is around 44% slip.

If you are doing over 45MPH in that picture, then my guess is that the boat has about 500lbs of water saturated in the wood.

A 16' boat with a fresh 2.4 on the back should barely be in the water when you are trimmed out.

Have you inspected the boat for water damage. Is this model full of foam like many other models? No water damage, has been stored indoors since I bought it in 2000 ( I haven't taken the floor out of it yet, it still has the factory foam in the floor ) I'll have time next winter to pull the floor and re work it

Good luck.

Hotdaddy, the speed I got with 9,500 was only 45mph --- 58mph was at 7,700Rpm

I am sure you checked it with a timing light. howerver, you still have not told us what pole you have the tach on.

Ain't no way a stock 200 can turn anywhere near 9500 rpm's! 9" below the bottom is 5"-6" too much. You can't have much slip at all. It's gotta be your tach is wrong. Here's what 8800 rpm's sound like! My motors are 14" higher than yours. 5.5" ABOVE the bottom.

I agree wit WILDMAN, with a 28P prop barried 9" below he can only be spinning no more then 5500rpm. Also, that boat is running way to flat in the above pic.

 

[WILDMAN]

The cavitation plate is 8" above the nose, which means you're dragging that huge plate under water. This alone will cost you at least 10 mph.

whos the pitcher?

willing to beg, borrow, or steal a pitcher for a good ball team, but we got some props, and will to test some, and willing to loan you one to try, and always in surch of a good pitch

Thanks wildman the 1st test run I did with a 23 pitch prop the motor sounded louder than that snipit ( my 200-2.4 is NOT stock, it's a 240-250hp-- got my parts from a guy that runs a hot-2.4 on his competition bass boat) I have a Ninja bike I run that at 11,000 rpm doing 1/4 runs lol, so top rpm isn't new to me.... When you guys asked about the distance my nose cone was from the bottom of the boat that was at the lowest position on my jack plate = 9 in, that's not where I run it all the time-- my last run the nose cone was set at 3-4 in below the V.. I can lift it so it's 2.5 in below the V-- I moved the motor on the jack plate( lowered it 1st run last yr if I wanted to I could have put the nose cone- 1/2 in below the V ) I thought that was a little too high

The pic you posted for me ( which I thank you for was my 1st voyage with the 2.4 on the boat was at Dale Hollow Lake in 2006-- it was not this last fall!, In that pic I had the jack plate set with the nose cone at 4 in below the V and I had a 24 pitch chopper on it I was at 48 mph--( the (prop went bad and I lost that power head ) I took bad advice, when that pic was taken ** there was a 70 sand bag in the nose** ( One of my friends suggested that, shakes head I told him I didn't need it but ** he is a computer enginer ** so I did it and after that run the sand bag got pitched on shore.. I told him to stick with the pc work and@$#*& leave the boat stuff to me LOL ) ** I'm going to replace the Tach this yr-- it was a used one the guy said it was Marine application but.. there is no pin adjustment only 4-6-8 on the setting--I set it on 6 for the v-6... With the Reed's I have in this motor --- I could take it full throttle till she popped and it would keep building power --- no restrictors--- I'm new to setting up motors ..... ( I'm the guy that does the glass repair and custom paint work ) ** My 1st boat was a 14ft GW Invader, I built it.. it weighted 250 lbs had a 14 gal tank in the nose for balast weight, I had the cavtation plate set 2 in above the V and it had a 115 inline-6 merc and I was clocked on Radar 23 yrs ago at 65 mph and my bottom carb had quick working on that pass ** I don't remember the prop pitch it was lol 23 yrs ago- that boat would run on the lower unit -- the boat was totally out of the water-- I built and set that one up myself.. When the weather breaks here in Indiana and the ice clears I'll start testing the boat all over again ((( what is the Dry Weight for a 1979--Tri-mate ll ??? ))) anyone know I'm going to take the boat the the local feed mill and weight it-- trailer and all.... That way I know the total weight, motor and all..

what pole is the tach set on????????????????????????????????????????????????????????????

 

[boatman4021]

Without some major mod's, that motor is not going to turn 9500rpm's. Look for about 6500 with a good set up. Reeds will not make it turn that kind of rpm's. If you do get it to turn 9500, it won't last very long. Just my 2 cents. boatman

what pole is the tach set on????????????????????????????????????????????????????????????

The Tach I have is a Auto Meter Marine application tach it dosn't have pole settings... it says 4 - 6 - 8 cyl. I have it on the 6cyl setting ...

Captain thanks for the offer to loan me a prop to test ( I might take you up on that I need to check the gear ratio in my lower unit this weekend and I'll let you know what I find and then I can go from there.. I'm about 2 months out from the ice being off the water here ) Again thank you very very much..

Thanks for the 2 cents I'm adding it to my checkmate piggy bank... lol. I wanted to say if you look a couple of posts back of mine my 1st test run was with a 23 pitch Clever and I hit 45mph on gps at 9500 rpm..... ( my motor is not stock the carbs and steel Reed set were off a 250hp 2.4 a local guy had hopped up on his competition bass boat ) , the carbs have been modified so there is NO choke plates-- i.e. no choke... so there is little to no air restriction going into the carbs .. 1st start up of the day I have to mist a little starting fluid in the carbs for it to kick off. ( No Reed restrictors on it so it doesn't top out at 6,800 like normal 2.4's ) I have a Hot set up on the motor and NO I'm not trying to run it at 9,500 rpm.... I want to get the right prop so I can top out RPM wize at 6,800-7,000 This weekend I'm checking the gear ratio in the lower unit ( my Fear is it is a 2.1 ration ) This would explain why there is only 500 rpm difference btween the 27 -28 pitch prop & there was only 2 mph difference I was at 57-58mph both times...


***This Weekend I'm checking the Lower Unit Gears before I go any further ***


Thanks to All for the Advice and Information.....

here is the problem. all their current tachs have those settings as well as a 12P. you need to set it to that.

if it does not have a 12 pole setting, you need to get a new tach that works with outboards.

OK Thanks... I bought the checkmate in 2000 and that's when I bought the tach evidently it's a older model I'll invest in a new one when tax check comes in........ but that doesn't solve the problem at hand 28 pitch and only 58mph on GPS. the gps isn't lying.. Thanks to all for the advice ..

 

[WILDMAN]

When it says 6 cyl, that's for a for stroke. A 2 stroke fires twice as often and will show close to twice the rpm. That's why your rpm is so high.

 

[illMATTic]

well in an earlier post you said the highest you had the prop shaft was 2.5" below the bottom of the V. this would still be too low to run a 28P chopper or like prop. you would want to get that engine up another 2" for the prop to really work the way it is supposed to.

On my predictor, I could not turn a 28P chopper until i added the LWPU and raised the engine. once I raised it to .5" below tha bottom, it really started to spin.

Ok I lowered the motor on the Jack plate 2" I did have it for 1 run so I could get it to .5 " below the V-- but was advized to run it all the way down to give the boat more lift.. This all depends on the type of prop that I'm testing right ?? Clever - Chopper- or 4-blade style , I was told that I would be very happy with a ( Hoss Triton prop 4 blade prop )

 

[illMATTic]

on my predictor I tried out many props. I found the hoss triton to be the best. It smoked the merc chopper and the mazco RE3 from low to top end. I ran a 28 chopper, 29 Mazco, and a 30 Hoss.

I ran the hoss .5" above for best top end. you have to feather it out of the hole but it still pulled as hard as my 26P laserII.

 

[illMATTic]

if you do infact have the power, this is what you want to run. A 28-30P Hoss Triton. See how it is cut? Plan on spending 300 bucks on one.

Its worth it.
