Top end prop for Viking?

[Fulltilt]

Yes I've used the search function, but the opinions are all over the place.

I have a 77 Viking with a 2.5 200 currently running a 26 big blade chopper, that is a havdfull when trimmed out. Hitting about 5500 rpms, maybe a little more but I have a hard time looking when it starts to chine walk. Motor is about even with the bottom, and yes it has been re-cored.

Looking for a good top end prop that might be a little easier to drive, and maybe faster.

I think you will do better with a 'HOSS' triton or hyperdrive (HPD) for sure. Better hole shot and more stern lift so it will run you straighter with more control and eliminate the chine walk.

Keep the trim to no more then +1 degree if you want the fastest speed. JMO

I'm sure others will chime in soon with additional good advise.

talk to mike bishop (motorheadbishop) think he ran a cleaver and has bin 110 in his old vking

Are those 'HOSS' triton or hyperdrive (HPD) over the hub exhaust?


I always thought cleavers were for tunnels mainlt.

Yes Hoss props are over hub but their blades are worked so you have excellent hole shot and top end. A great all around choice. The allison's boats love them.

Fulltilt Cleavers have very little lift its probably the fastest prop made they run great on hydrostreams, try a small hub wheel like a chopper,cleaver,mazco,triton get your motor height up so you dont have so much bite EVEN with the pad is to low for your setup Try 1" above it will help the Walk and let the pad sit in the water so you can drive you dont need much lift. If you Fly that boat with a good running 200 MERC you should be running Mid 80's the 26 should turn up 7000 easy. Long Ear choppers if balanced run Great and are fast if out of balance run like Crap. Sounds like you've got the motor Burried, prop out of balance maybe?? get the motor up it should help steering and RPM's should come up You should have a Screamer if setup right!! Good luck

[Fulltilt]

I was just estimating on the prop shaft height. it's probably higher since the former owner gps'd it at 85mph.

But I can't drive it that fast with this prop.

:iagree: When I owned my HStreams the fastest I ran was with a Mazco Cleaver. You suffer with the hole shot a bit but once that puppy bites is right on!!!

Thanks.

Previous owner said a Masco was the easiest he had on it to drive, but I don't think it was a cleaver.

Guess I'll start looking for one. I'm thinking I can move up to at leasta 28" with the smaller blades. Maybe a 30"?

[HStream1]

He probably ran a Mazco RE 3 or 4 if it wasn't a O.S. Cleaver.

Also if you are turning 5500 with a 26 Chopper you better stay with a 26. A 26 is a 26 is a 26. You try a 30 and you could loose as much as 1000 RPM's.

[Fulltilt]

I think he said RE-3.

Said it was easier to drive, but lost a little on top end.

[Fulltilt]

Thanks for the advice on prop size.

One of my problems is, I can't spend much time looking at the tach when I have it at WOT, so I'm not 100% certain on the RPMs.

I was just thinking a cleaver would have less blade surface.

Interesting....I just happen to have a Mazco OS 14.5X30 cleaver I was thinking about selling. :D

In theory at 0% slip a 26" pitch prop should push a boat 26" in one revolution. There is slip involved but the base line IMO is not to exceed 10%. Anything less is a +++ anything more is a ---.

You have got to be able to know what you are taching at different speeds to be able to determine what your prop is doing and especially at WOT if you are seeking top end numbers. But the sooner a prop hooks up all the better. Some hook up quicker than others and will not react the same on a similar hull design i.e. (2) look alike V kings. The same prop used on either boat will show two totally different results.

You have got to be able to focus and know what your tach vs speedo, water pressure, water temp is doing at all times. It only takes a nano second to look and process the information. Keep a note pad handy and take notes on different set ups. And only do one change at a time. Once you find that sweet spot and the sweet prop for your boat and set up leave well enough alone.

While I don't have experience running a bunch of different props on mine, I run a 27p SRX and I have zero complaints about it.

[MDevrow]

Greg dont tell everybody!! those props are a well keep secret if worked right they will run some great Top End Numbers and are a good all around prop if set up right.

[Fulltilt]

That is going to be my problem.

The boat is set up good for someone who can drive through the chinewalk, and get to top end/max rpms.

I've seen a video of the former owner trimmed high and not chinewalking.

I thought I was driving through the chinewalk and getting good exceleration out of it, but a guy I run with told me I wasn't trimmed out far enough, based on the amount of boat still in the water at wot.

Now that I'm trying to trim it out further, I've got my hands full.

Here's some advice. To learn and handle a boat on the pad. Find a friend that can drive another boat and make a wake. Learn to rest/balance the boat on top of the wake and balance it. You will learn a rythum. Apply that rythum to the boat when running. To be able to drive through a Chine you need the horse power. And with what you describe you don't have it.

You have got to learn to drive the boat and only seat time will teach you that. No prop in the world is going to teach you to drive a Chine situation. Some are just better than others.

GOOD LUCK!!!!!!!

[Fulltilt]

I was able to drive through it until my friend convinced me I need to be running with the bow higher.

Used the advice on here, slightly turning, and also balanced on a wake.

Believe me I was practicing. Just thought there might be a better prop to be learning with.



I don't understand this part of your posting, since the previous owner can drive it trimmed out. Why doesn't it have the horsepower?


"To be able to drive through a Chine you need the horse power. And with what you describe you don't have it."

[HStream1]

He wasn't driving through it. He knew how to balance the boat.

[XstreamVking]

Do not get in a hurry to find out the very best top end #s. These boats take a good bit of seat time to master. I have had mine since 1983 and have driven most all the fast streams. First V-6 Viking I ran was 1978. Learn the boat by running it, push it but don't get outta controll. You will master it over time. PS... The easiest to drive prop is gonna be a cleaver. You can trim up some and will have better controll. JM2cts

[Fulltilt]

Just using the terminology I've heard on here.

[Fulltilt]

Thanks.

I guess that would be a better way to put it.

I'm looking for the easiest prop to learn with.

Learn with the one you have !!! After that everything will be a cake walk. But you need to learn to drive first.

You also need to listen to the voice of experience;)

Again good luck!!! I'm outa here for now.:leaving:

The 26 Chopper should be a pretty fair prop to learn with. I love mine on my allison and liked it on my Hstream vegas as well. It takes practice to handle a pad boat! I spent an entire summer learning to drive my allison and am by NO means an expert. Take baby steps with speed and work your way up, not just nail it. Remember Long slight left turn and learn the boat. You should never have the wheel going right, slight left pressure to center and don't over drive it. I know it sounds like a lot but it's a skill not a power. Take notes on your setup every time out work with the jack plate. Best advise be safe, they WILL bite if not respected.

Vipers, Vectors and V-Kings run top end best with the Cleaver prop. You don't drive these boats with the bow pointed towards the moon. They don't need a lot of bow lift unless some bonehead has put the tank in the bow. I run an OMC 29 Cleaver for towing skiers and my favorite 32 Spinelli Cleaver is the best prop I have tried on my Vector. get a Cleaver and learn how to drive it and you will love it.

[rkmirage]

28p big eared chopper with an offshore cut. Don't try to drive though chine walk, put it on the pad, balance it then increase the speed slowly, these boats take time to master, don't push it, give yourself some time.

[Laser88]

In my experience, the lightening ET works very well for the V-King. It has a great holeshot, pulls like a sportbike once on the plane, and has a great top end. The only negative is the cost... I have no experience with a cleaver, so I might look for a small ear to test... I agree with the comments about not getting a big hurry to learn hot to get to the top end.

One other thing that helped me was dialing in the engine height. I tested numerous positions with making 1" adjustments, and found a sweet spot of sorts... Even without a nosecone, I have ran to 87mph on the gps while pumping 25psi water pressure, and it was stable! Good luck!
