1895 Yarcraft Prop Question

[SLE]

Yes, I hate to do it but its another prop question

2000 1895 Storm SC with an 06 225 Merc Opti. Currently I am running a 21P Tempest Plus with all the PVS hole wide open. The boat runs between 56-58.5 mph at about 5700 RPMs. The top of the operating range is at 5750 for this engine so I believe I have about the right pitch. I just keep thinking that maybe I should broaden my horizon a bit an try a few different props. I have a vengence as a spare but have found the tempest is better in every regaurd so the vengence is nothing more than a back-up. I figure if I'm gonna have a SS back-up why no have one that I can use when I need more bow lift or a better hole shot or a better ride or maybe more speed hence you'll see that I'm not after a single criterea but instead a max performance prop.

The fist would be a 22P or 23P Enertia. I figure with this I should gain a mph or maybe two and be able to spin within 150 rpms of the max 5750. I am also contemplating rasing my engine a hole and maybe two but I need to install my smart craft monitor so I know whats happening with my water pressure. I am thinking between the prop and raising the engine I could net maybe +3mph. The question will be if I have enough bow lift at lower speeds (25-40 mph)?????

The second would be a Revolution 4 or a Trophy 4 Blade. With the tempest it's decent out of the hole but it's not what I'd call neck snapping. I'm thinking that with either of these props I should have a much improved hole shot and the bow lift should be better which should yeild a better/smoother ride when it gets choppy (which is everyday in ND). Is my thinking flawed??? The question becomes do I stay with a 21P with these props????

Lastly I have access to a High Five so I thought I'd give it a try just for the heck of it. After running the High Five I should have an Idea of how the 4 blades should do since they should fall some where in the middle of how my tempest performs and how the High Five performs.

In the end I really don't know what I want out of the prop since I don't know how much they will affect the ride / hole shot / top end speed from what I already have? Maybe what I really need to do is send my tempest in, have it worked, and forget about the rest!!!

Lastly I do notice at lower speeds just below getting on plain (say 2000-3000 RPMs) I have a vibration that you can feel though the whole boat. Is my tempest prop causing this or is this a trait of the big Opti's?

Thanks

Steve. I have the same boat with a Yam 225 EFI. I run a 23 Tempest at about 5600, and have topped out in perfect conditions, full gas and tourney load (no livewell yet ) at 60.4......ONCE! I would say the average is aroung 57-58. The livewell has a significant impact (-3-4 mph) in this boat due to its location midship, however, it is also a reason why this boat rides so well. Also note that your motor is a 1:175 gear ratio, vs my 1:181. meaning yours is a little harder to turn. You post good questions, and I understand your desire to create the best performance from your combo. #1. Get your water pressure guage working properly. You need to maintain at least 15 pounds above 3500 rpm. #2. Get your prop shaft up to about 4 1/2 inches lower than the bottom of the centerline hull. This might even be the bottom hole on a Merc., it is on my Yamaha. Now for the props. I have tried many props including 21-22 and 23 pitch in several models including Trophy small hub 21 (my backup) = 5800 @ 56 mph. 22 small hub high 5 = 5800 @ 53 mph. 21 Rev 4 5400 rpm @ 54mph. (these turn hard) . The best overall has been the 23 Tempest. If I were to try additional props it would be a 23 large hub High 5, a 23 Trophy, and or add more cup for more lift for my 23 Tempest. IF I were you with the 21 Tempest. I would have it Balanced and Blueprinted by Mark Croxton, and have him add 1 degree and add cupping. http://www.bassboatcentral.com/marksprops1.htm
This boat does like the large diameter 3 blades, but they have to be able to lift the bow as they run so flat and smooth normally.

Thanks Ryno!! That right there is the exact information I was after. I beleive I owe you a cold one if you ever come up to central ND because I'm certain you just saved me a pile of time and money!

I haven't been using my aft livewell much unless I am keep a few pike and want to keep them seperated from the walleye so I don't have a bunch of slime on the walleye when it comes to cleaning time.

Funny thing is the fastest I have ran was in mid June, 75 degree weather, 60 degree water temp: Rear live well, bait well, and cooler were all full and front bait well was full. I had 55 gals of fuel and 4 guys at an average weight of 200lbs each. We also had a regular chest cooler (in the back of the boat) that weighed probably 65lbs and my normal gear plus 2 extra tackle boxes. We ran 58.4 mph in a very slight chop. Thats the fastest I've ever ran and coinsidently the heaviest I've EVER been loaded. I think the key was the slight chop and having just about ALL of the weight towards the back of the boat. It was a little sluggish out of the hole! I've ran this rig with much lighter loads and on average it runs between 55.5 mph and 57.5 mph depending on conditions.

I think as soon as I get my smartcraft monitor installed I'll raise the engine. From there I will probably take your advise and have the prop worked to have a little more cup and maybe anothe degree of pitch. Do you know what Mark charges do B&B a prop?

The only question I have left regaurding the props is: did any of them seem to offer much better bow lift or a significantly better ride over the tempest?

Thanks again!

never mind about what mark charges, I wrote that before i checked your link!

Talked to mark the other day. I now have a plan of attack (grin)!!!! I'm gonna get my smartcraft monitor installed so I can watch my water pressure. I'll raise the motor so the prop shaft is 4.5-5" below the keel of the boat. I'll run what I have to find my baseline assuming I keep enough water pressure. If I don't, I'll have to dial in the motor height first. Mark figured that just his balence and blue print of the prop alone would gain me RPMs as will raising the engine. So since I'm already running near the peak of the RPM range we are guessing at this point that he'll have to add 2 degrees of pitch to get my Rs back where they should be (5600-5700), he''l balance and blue print the prop and add cup to keep my bow lift as I will likely loose some bow lift when I raise the engine. In the end I'm hoping to pickup between 3-5mph between the prop work and raising the engine (It's really low right now). This should put me right in the low 60s for speed (BIG GRIN, lol). He thought it was pretty realistic and figured the prop work alone would net me 2 mph and maybe 3 mph.

It upsets me that the Bass Boat guys can do this same stuff and pick up 5-9mph depending on how poorly their stock setup is! I guess I need to remember that those same guys would be sitting on shore or really wet 60% of the days I spend on the water here in ND.

How do you like the rig so far?

Interesting your not getting the speed I got with my 21p. I hit the rev limiter a couple times while it was still accelerating. Both times I was at 60+MPH when the horn went off.

Enjoy the boat!

Jack, the boats been good! Even managed to put a few eyes in wet well although my sister inlaw put the largest fish in the boat so far and it's the first fish she's caught in two years!!!! It hasn't seen the as much use as when you had it but I've been out about 20 times through the 12th of July, been dry docked in the shop since due to work. hopefully I start getting back out in the coming weeks.

As far as the boat goes I couldn't ask for a better deal and it's drier and rides better in the big stuff then any other boat that I've been in. The motor runs like a champ but I wonder if it's a difference in speed is due to the difference in elevation, or maybe how I have the boat loaded, or maybe the tempest prop that I have is a little off compared to the one you had on it (most likely). Regaurdless of a couple mph, because 56-58 is plently fast, she's a good machine.

I've done quite a few small things getting it the way I wanted and fixing a few minor things. I removed all the stickers, filled a few small nicks in the gel coat, buffed and waxed it. Changed the gear lube, drained the water seperater and greased all the zerks on the engine. Painted all the ram mounts, changed out a few interior and livewell lights and got them all working, put a new set of Class 29 interstate deep cycles in for the TM. Changed the copilot battery, fixed the holder for the marine band mic, rewired the 12V receptical, had all of the seat backs reupolstered, changed out the bunks on the trailer and replaced the carpeted trailer steps with aluminum diamond plate, picked up a tempest prop, changed the leaf springs and hardware to 4 pack springs (I broke one so I changed them both with a heavier set per the manufacturers recomendations). Added a Nav chip to the X19c. I'm sure there were a few other little things but when I guy has a new toy you don't mind working on it so long as it's nothing major. I think the only real problems that I've had so far is the trolling motor plug burned out so I replaced that and the timer switches on the back live wells quit but both worked at the first use so I chauk them up to a matter of keeping things working since anything mechanical can and will break at some point!

I have about a 1/2 dozen things I still want to do. First is to get the prop and engine height dialed in. Install a smart craft system monitor where the indash flasher is now and remove the flasher. Install a keel gaurd, wifes request since I won't beach it for a bathroom break, lol. Permanet mount the GPS puck (the cabe and mounting plate are on order), and eventually add a second sonar/gps unit to bow and net the two units together. Lastly I need to have a travel tarp made for it. The tarp you gave me is fine for sitting at the lake but would probably get tore up if I traveled with in on. The first trip to the lake that I towed it behind the camper about made me sick after I got to the lake, with no tarp on it the dust from the gravel road was about 1/4 thick over the entire boat! But a few cold ones and bucket of water and all was good again.

All in all it's a good machine! If you find you're self in the sakakawea area feel free to get a hold of me for a cold one or maybe a day on the water.

By the way are you still running your 07' TFX or di you get and 08'?

Steve

Glad your enjoying the boat. I sure did while I had it, and yes, I'm still running my 07.

Take care.

Just another input on sum of my trials. I am running a 1999 1895 yarcraft storm. mostly on SAK. i have a 1999 Yamaha V-Max on mine a 9.9 yamaha four stroke on passenger side. a motor guide PinPoint ont front with the matching pinpoint graph. That is 36 volt trolling motor so I have Three optima deep cycles on board also. my motor is one hole from the top as that is wear it was when i got the boat. the only time I have had any aver heating issues was when i very first got the boat from the dealer. and they fixed that right away. it endeed up being a kinked hose up under the hood.

it had a 23pitch Pro on it when i got it and I could get about 56-57 with a full load out of that prop. but i also was not completely happy with that so i tried a 21 pitch high five and that prop was just way under pitched as it would snap your head off coming out of the hole but would hit the rev limiter real quick after that. Now i have a 21 pitch tempest plus and this prop is alot closer to what i was looking for but I still over rev. Unless i am 100% loaded gas, live wells, gear, and 3-4 guys it will turn 5850-5900. local dealer said i sould be running around 5650-5700 for max performance. I have seen 61.2 on the max speed spot on gps. that was on fort peck. i resently dinged my prop up pretty bad on sum rocks so i am not sure if it is able to be worked over and pitched up.

Even if it is able to be worked over could it be bumped up to a 23 pitch?

I am looking for a decent hole shot but am more in the marcket for speed as i would rather make up the hole shot buy passing sumone then rather then jumping them right out of the hole and then be passed.

The loggin name is KidWalleye I am just having sum issues getting logged in as of right now.

Thank for the info above and any other you can offer, Hope sum of mine helps.

From what I understood they should have no probelm getting it repitched. If I was in your situtation I would send it in and have them fix it, balance and blue print it (which will come with them fixing it), have them add cup to the blades to gain bow lift, and pitch it to a 22 or maybe a hair more. This is basically what I'm gonna have done. The whole thing will cost you around $350-$400 + shipping but you'll have a prop that is actually better than when it was new! The other thing I notice is with these boats I've yet to here anybody say they had to mcuh bow lift with ANY prop! Their big and heavy so the more cup they can add the better. Good luck
