Re: Raker vs Raker

You cant make a pad its usually built into the boat..its going to be a fine balancing act when ya get it up at those speeds.

Re: Raker vs Raker

Okey Ron,

will try to keep it straight.....??!!

Compression was Ok,
2= 127psi 1=130psi
4=120psi 3=120psi

Carburators is off, they did not look so bad,
reedcage is off.....Boyesen is on its way,

New waterpump is in, two upper holes is blocked and new lower holes is made as described by Dale and Kenny here on the forum.

Anyone know if I will gain anything with the 78/79 1 3/8 instead of my 1 5/16 carburator, low/midrange is not so important since my boat is less than 1000 pounds total with me and fuel, it is toppend that is interesting.

Will I gain or loose toppend if I take away the reed stuffings? Any experience with this?

Anyone know where to get dual stering? the one I got now is getting more and more free play and it is an ultraflex rated for 40/50hp, I have run a few boats with hydraulic steering but they had no feel so I want cables, no one over here that I have spoken with have heard of dual cable steering...?!

Hope it will be som testing during nex week.

Ronny again

Re: Raker vs Raker

The reed "stops" will not be used with the boyesens, but I'm not sure there would be any reason to remove the filler blocks...
The 1-3/8" carbs might gain some top-end, but porting may limit it some.
Dale will catch this and let ya know for sure....I don't think there is anything left he hasn't tried on a V4...

Re: Raker vs Raker

Okey,
thanks again Kenny,
hope Dale has time to share some of what he knows...?

Re: Raker vs Raker

You can try the bigger carbs but you may find the gain isn't worth the extra fuel burned. The rubber intake stuffers in or out don't seem to make much difference although in theory it should.

As far as dual steering, that's a delima. T-flex makes a dual cable but it's still tied to one rack so it's a parallel entry deal. That should be OK on a V4 but I'd rather have the old style twin racks and opposite entry. You can find the Merc Super Ride Guide but that's an over-engineered, complicated system in my opinion. I'm going to try the new T-flex "Allison" hydraulic cylinder on the Hydrostream.

Re: Raker vs Raker

....thanks again Dale..!!!

Second test today, it sure was a wild ride but verrrrry funny, I have a big smil over my face now.

Engine totally stock with Boyesen reeds.
1980 140 Rude.

I got it to 65,6 mph, engin cavitationplate about 100mm above bottom, at no trim and full speed I get 5500rpm and 57,5mph, then I trim up in small steps and I guess I got it to 6000+ rpm but the tachometer started to bounch and then it went dead, som wire is of I think.

I have a omc waterpressure gauge, T-ed into the telltail, at wot the needels bottoms at over 30 psi, at idle I have around 5-7 so water pressure is OK.

I will raise the engine some and get the tach fixed and test again

Its kinda wild to drive and my 1/4 turn slack in steering does not make it any better so better find a new steering before the boat throws me off...hehe its OK as long as I manage to hold her steady but very scary when I give some wrong steering input..

Re: Raker vs Raker

sounds like your having a heck of a time.dbetter find that steering before it digs in on ya and gives a really wild ride.

Re: Raker vs Raker

I see a wet wallet in your future.....8)

 

[Dhadley]

Re: Raker vs Raker

There are 2 kinds of race / performance boat drivers. Those that have been wet and those that are gonna get wet.

 

[Gammabusa]

Re: Raker vs Raker

hehehe I have a strong feeling that the first thing to get wet over here is my underwear, had a qouple of scary moments today but will raise the engine and fix the tach and see what happens, aiming for 70mph....

never heard of it but bought a Ron Hill 27" chopper, or was it a cleaver??? on ebay....dont know if it will suit my setup but time will show.....

I have an 24 raker old type now, is it 25" to these gearcases?

 

[Gammabusa]

Re: Raker vs Raker

....did som testing, engine is up to propellershaft is even with bottom, tach is fixed,rectifier was gone, had 25 psi on waterpressure at WOT, got it to 6000rpm and 65mph, it went crazy,huhu almost wet wallet....GPS flew over board, new is bought,had a couple of runs without GPS and got it to 6200 rpm but does not know if speed was better or if it just was slipp, anyone that can confirm that my gear is 2:1? at 6000 I get it to theoretical 68mph and real 65mph= less than 5% slip and thats kinda low is it not?

If weather is better tomorrow I will test the 22 Raker and see whats happening....

One big failure, I loked at my modified lower waterinntak and thought, hey lets make them BIGGER, upp with the drill and big ****, gearoil came out, hehehe, has to epoxy it togheter and install a low water nosecone or a hull mounted waterpickup, anyone has some advice?

Will a nosecone make it more stable or will it just rub of some speed??

Thanks again

Ronny

Re: Raker vs Raker

The nose cones are the way to go,i wish i could aford me one right now.dyour doing some good runs you ought to 70 before me if ya can hang on,and dont let out of that baby real quick or you will have a wet wallet for sure:^as for the nosecones take a look at bobs machine shop on the web.i would post a link but im not that talented yet with the puter.

 

[Ron G]

Re: Raker vs Raker

i forgot to mention the nose cone will be better there desined for raising high and fast boats the ones on the outside will cause to much drag,and on your rig will probably hamper the handling.did ya find some sterring cables yet?

 

[Gammabusa]

Re: Raker vs Raker

Okey Ron, d

No one hear has heard of double steering cables and they dont belive me either, hehe, but earlier today I saw that iboat here had listed with 12` cables, I onley need 10` but guess its okey with abit to long, I have been over at bobs web and if I buy a nosecone it must be a kit and mount it myself, I dont think I can afford sending my gearcase over and back again, time will show, maybe I find a cleaver idea to get away that oil leak I made with my to big drill....I will of course let you know if I reach 70, what is your best until now, any picture of your boat?

Ronny

Grrrrrr...
International Orders
Presently, we only ship within the U.S. and Canada.

iboat dont send abroard, better start searching again.....

 

[walleyehed]

Re: Raker vs Raker

On the pull-pull cables, I believe you want NO slack....
For the nose cone...I think the "Bob's machine" cresent nose piece may be the choice you want...Dhadley would be the best to offer advice on that...I know he has "tested" several cable set-ups as well, under racing conditions....and of course the rest of the pack was behind him, checking out the rearend view of his rig....

 

[Ron G]

Re: Raker vs Raker

Heres a pic of my rig,i jacked up the motor another 1/4" an got 66mph with a full load.im about as high as i can go without a nosecone.still going to play some more with it to try to get some more out of what i got.

 

[Gammabusa]

Re: Raker vs Raker

Nice boat Ron,
I had to search around on the net to find out what all the stuff in/on it was and I found out it was fishing equipment, hehe, never seen that rigging before but found on the net it is common over there...hehe

Thanks for nice picture

Ronny

Re: Raker vs Raker

Thanks Ronny if i could loss the trolling motor 2 batterys and 150lbs of tackle i might make it to 70mphd
Are you doing the nosecone yourself?if so its got to be just right i believe maybe Dale has some input on how to do it,i know he's speant alot of time working with them.

 

[Ron G]

Re: Raker vs Raker

Hey Ronnie you all right?i havent herd from you in a while and was wanting to make sure you didnt get wet:%
