motor offset, whats it all about?

[Techteam]

So thanks for answering the questions, I think a lot of problems stem from the steering. I've never liked hydraulic steering the very way it operates make it difficult to drive a v hull like the ring. Your trying to balance the boat by small quick steering movments around the straight ahead. I am often horrified by the video I see of those Honda boats it's no wonder they handle so badly when the driver looks like he's in an old american movie he's moving the wheel so much. Say what you like about wire cable steering but if it's set up correctly the boat is 100% easier to drive. Try and sort the steering so there is minimal play around the straight ahead.

then raced with 21p laser2 which was slightly more controllable than the chopper

iv got a worked yam-prop 23p that ran very well on the 18 but was very nose down compared with the chopper. gonna move motor down 1inch below leave it central and try the yam-drag prop, hopefully tomorrow

is the same said chopper up for grabs...need to get the bow up on my marshan

Was the 18 footer offset ?
That seemed to go well I would mount it identical on the 20 that 18 was set up by big Dave T
On your avatar the ride and trim setting seems a bit out of kilter -trim it in a bit
The 20 should be very similar to 18 to drive

yeah iv been looking into cable steering as when i first bought my 18 it was running a 1st gen XR2 150 with single cable teleflex, the feedback was AMAZING but trimmed up id litreally have to lean off the steering wheel to get it to turn!!
the hydrolic, no matter how much i bleed always has some movement, and yes it is crazy the amount i twitch my steering wheel when driving to correct what can only be movement in the hydrolic system

what are my options on steering an is it difficult to set up or expensive? i have seen the pulley cable steering, am i right in thinking this is 'ride glide' steering? or is there a twin style teleflex system option?

think this is definetly an issue i should address but dont thin it will cure the bow happy lean i have, think thats motor setup issues, didnt have time today but am gonna drop the motor and try the yam prop tomorrow an c

sorry, dont really wanna sell the chopper, works well on my 18 and been really well worked by PR.
who knows might still run the 18 1 day

[martynwilley]

an no the old 18 wasnt offset and i ran the bullet level with the V on that, great top speed, but in heindsight would have prob run better in the rough 1inch below

i think channel island waters are rarely calm enough to run level with theV and get the top speed, i saw 74mph in the 18 once an 70 two or 3 times, but never hit more than 65 in a race!

Have you considered getting someone like foxy to take you out in it and offer some advice?
I did with my old 16 and the difference was amazing, I'd recommend it to anyone over here, he really does know his stuff. He'd probably have the problem solved in an afternoon all for a couple of beers!

Drop engine 2 or 3 holes if you go back to cable steering you will need a torque tab on the skeg !!
Seastar is probably the only hydraulic you will get away with as there is very little creep.
The 20c is nothing like the 18 !! Be very cautious if you try the drag prop as when you get into mid 70's it will blow out and send boat sideways.
Try a small hub 24 or 26 Laser. Get someone who knows Rings to test it.

i have been told this by a few people locally larby, are you talking about jeff fox who raced the old relentless in last race?

if so i gave him my old facet red top and pressure reg for the last race, so he ows me a favour

would i be right in saying he works at M&G? i dont have a contact number for him, pm me his number if u have it please larby

Martin I had a stepped 20 which I brought as a project cos it had the nose ripped off it in a nose stuffing incident .
It was called no limits and was a lovelly metalic Blue.
Underneath the original gell was a white hull,red deck and a black engine well.
If you look undeneath the deck of yours there should be a ring sticker telling you the year and model of the boat-is it a 20c ?
Go careful with the step when prop testing-it could be a bit lively

[larby]

Nope, I'm talking about mark, his drunk brother. He's the one who shouts stuff from the back in meetings! Best guy on the Island to take you out though.

Simon, after a quick check, martins hull is a 20c step hull, but the step has been filled in, so Its just a straight bottom, so not too flighty as they used to be known for!

I think the problem is down to the masses of play in the steering arrangement

[Big Dutch]

Bleed the system and make sure you have got oil in it.

Nothing to do with that...

[Big Dutch]

Is it the Nut behind the wheel then ?

[martynwilley]

lol, no its the 'magician engineering' steering plate i made up in the garden shed 1 night thats at fault there

had a new 1 and a nice bush made today by a mate, this 1 aint moving!

yeah the steps have been fillled, you can see where they used to be whoever did it thou must have made a good job, cuz i didnt notice it when we soda blasted it right back to bare gel!

the hull when blasted back to origional gel was white with grey sides and screen, was owned by andy priaux and his brother under the name 'asitic' then moved to dark blue & white 'just a mirage' then sprayed a horrible chav saxo blue then i got it

[Big Dutch]

So there you go Martin-it was the nut let loose in the workshop that caused all the problem.
P.S don't forget the locktite-remember Sark poker run ?
Theres some in the club that reckon that 74mph you hit was when Paul M was towing you back(and you still owe him a pint !)

[martynwilley]

hahaha, tony F will happily tell you he paced me at 70mph towards herm, and that wasnt flat calm or the fastest i pushed it to!

oh yes iv learnt to use locktite by the bucketload! and shakeproof washers

[Tom59]

Ello Martyn,

Interesting, sounds like we are having similar problems! After a few sea trials my Ring 20c is still leaning very badly to port - I believe its all down to the prop torque!? The old man has also taken her out and has had the same problem! We are in the process of playing with the offset and height of the motor as well. I have also spoken to Mike... Will keep you posted.

Have you had any joy with yours?

right ok,

been out and tested today, running an inch an a half of offset and bullet 1 inch below V with the 23p worked yam drag prop. (steering all sorted and solid as a rock)

MUCH MUCH better!!!

no port lean anymore but stil very flighty on the bow, was fine oer the calm, i had it pinned and revving nicely, but over chop the bow is just too light!!!

race next sunday and really dont know what to do, im gonna try 50kg of sand righ up fromt in the bow tomorrow and c what happens, might cut out and modify the deck so i can slide my fuel tank forward to behind the front seats, just seems at the moment that all my weight is in the ass of the boat and the front is light as a feather!

[larby]

Well seeing as all the weight is in the back and you're finding the bow flighty as hell, you may be running the wrong prop using one specifically for bow lift?

Try leaving everything in the back and give a cleaver a go instead. Goes against everything rings normally do, but it'll lift the arse (where the weight is) instead of the bow (where it isn't!)
