Is that why tires only go flat on the bottom?

Ever wonder why Cranes have long legs?
So they can reach the ground!

its because tournament ski boats run counter clockwise on the lake and this prevents the driver from falling out on the left turns, they do this with Nascars too, heavier springs on the right side of the car

Mr. Ralph will make you feel like a best friend as soon as you shake hands with him. I met him once and won't forget it. His signature will be on proud display at the Chattahoochee run!

Mr. Ralph will be at LG09 and he can answer this question to all.

And he will tell everyone why the steering wheel is on the right side of the boat as well.

And he will tell you the story behind Correct Craft.

This will be once in a live time to meet this great man in person.

So please try to make the event!!     He has told me the story, but I will let you hear it from him..

The water level here at Lanier is in the middle of a law suit that's almost 20 years old.   

Happily we are only 6.46 feet low and that is so much nicer than where we were last year at 20'+ and we have been getting the rain that seemed to go somewhere else this year.

You know when a train goes around a corner, everyone has to lean against the side of the train on the inside of the curve. Does that work with boats?

Greg,
What about your lake? At times they seem to draw out so much water that you would be going downhill! BTW, how is the water level this summer?

and....the engines couldnt turn high RPM's and a bigger prop was needed, along with the narrow boats they would torque

Port side helms on old CC's??? Billy is correct that prop rotation and helm position has been discussed at length. Briefly, it's due to the flywheel forward position of the old marinized engines that need a RH prop.

it has something to do with the water not being level on the port side of the boat, they take this into account and offset the boat

Not...........
This topic has been beat to death more than one time. Do a search on Reverse Rotation and a lot of info will appear.
It started way before the Maloons and their first boat in 1927..

David, prop rotates to the right, driver sits on the right. The "down force" created by the prop turning RH makes the hull lean to the left.

I have been wondering about the RH rotation issues as well.

Assuming these boats were only designed to run on mill ponds with only the driver, wouldn't they lean even further to the right with just the driver in it? The prop rotates to the right, and the driver sits on the right. If this were the scenario, wouldn't it make things more balanced to have the prop rotate to the left to keep the boat from leaning too much to the right????

The scenario of having a spotter and a timer makes a lot of sense. Then I can see why a RH rotation prop would be used. Two people toward the the center/left side of the boat, and the driver on the right. A RH prop would make it more in balance.

Too much time on my hands to think about this sort of thing!

I try to always promote testing/checking. Before you go and get a starter "thinking" it's the problem:

Battery volts/condition?

Cables/terminals condition?

Voltage across starter relay (solenoid)?

If you need some help with doing some of these checks, we'll be around and always happy to help.

That's a pretty sweeping statement. These are tournament ski boats, there are many situations in thier use that skiing with no spotter is perfectly reasonable. A very good portion of tournament ski boats in 1990 were never registered and spent thier entire life on private purpose built ski ponds. My friend dave and his brother have skiied on thier pond 6 months a year 4 times a week for the last 20 years and maybe had a spotter with them 12 times. With the amount of runs it takes to become a high level competitive skier it is not reasonable to think that you will have two people constantly available to watch you ski... its hard enough to find a driver.

     I will absolutely flout the law myself in the pre/post season ski runs if need be, granted we are consenting adults, experienced skiers and drivers, wear a coast guard approved jacket, don't try this at home etc etc. Ask yourself if your safer being pulled through 4th of july boat traffic by some wally and his 13 year old spotter, or by a qualified instructor and lifeguard with the lake to ourselves.




Actually the boats are designed for USA water ski tournament ( and previously AWSA) specifications where a judge and timer would be riding in the boat. They were not designed for the driver only private ponds. I go along with the previous statement claiming fat drivers and much smaller spotters. Thats how I run.

On PCM Engines...
On all engines, the Serial # plate indicates both engine and propeller shaft rotation. (Example: PLD-WV-R20 and PLDWV-L20). The "L" following the "P" indicates the engine rotation. The "R" and "L" following the "V" and preceding the "20" indicates the Propeller Shaft rotation.

Check your transmission tag. If 1 to 1 =RH    If 1 to 1.23 = LH

Many states (and countries) have laws that require an observer- but many, including Florida (the home state of Correct Craft and the waterski capital of the world) do not.



I have a Ski Nautique 2001 1989 with 351w and the big muffler thing.
How can I determine if my motor is LH or RH??

I think my prop is RH, but I want to know if my engine is LH or RH because I think my starter is on the rope (just klicks when turning the ignition some times).

back to the program, I guess im stirred up and the reason is on the 4th I ran into a guy at our local parade, he lives within walking distance of my house, I sorta knew he was my friends brother, not a close friend, but a friend. I told him you look like your brother, and he replied, you see that guy over there? I said yes, He was the only one out of 5 that survived hitting the side of the barge at approximately 60 miles an hour that night, it was his bachlor party...not a ski boat, but it was a boat... the point, would you buy a car without airbags? probably not, because you want to increase your odds of survival if you do get into an accident and one other point on motorcycles, another friend would bragg to me on how safe he was on a motorcycle, been riding for 20 years, no helmet blah blah, got clipped from the side....accidents happen, thats why they are called accidents, you cant control accidents but you can control stupidity, probably a harsh word but it fits.
too add, believe me In my early 30's I thought the same way, case of beer on the boat, lake patrol always flagging me down, and if i was a closer friend to the guy above I probably wouldve of been right next to him egging him on to go faster

460's belong in dump trucks not boats.. i did forget to mention in the midst of the bad week he did bring the boat back one other time and said it wouldnt crank anymore, i did ask why the top end of the engine filled with water and i had to pull the plugs and pump the water, he didnt know why, I have to use foul langauge mf, it poured the night before and he left the engine hatch open,,,,,,this will be one i will remember....and the bad part about it is he'll hire Dewey, Cheatum and Howe, needless to say Im buying another engine

A cork or a front seal?    

We heard at least 1 trans job in the making on the way home from the fireworks. Everyone turning north was following 1 boat that should have been in a dock somewhere. We scooted in front and showed him where the channel was. Beat everyone up here back by 10-12 minutes...pumpkin power!

I swear to god, yes he does, I put 5 hours on the boat myself last Friday, he said he heard some ticking (one side of the rod was snapped) then he did it in when he powered up....he said he had to get to back to the dock..
I had intuition on this one, and called it, i think i mentioned him in an earlier post......his last words were, will uit be ready for my West Virginia trip Monday....i blew a fck in cork

it really boils down to is it safer with or without a spotter? i think the majority will say yes with a spotter, sorry for the rant, sometimes i base my opinions on the mentally challenged boaters and yes with you guys i would glady ski behind the boat without a spotter

I suppose texting on a cell phone is not a bad idea either with the kids in the back seat, sure its easy to keep an eye on the skier, who keeps an eye on the boat crossing in front of you...there is a word that pops into my head......multi-tasking
remember its just my opinion, i really think it is unsafe, i deal with alot of boaters, and seen them panick it a tight situation
