LOGICAL THINKING,,,because if a #5 ( 3 a ) is rated @ 800 and has bigger shafts ,gears and bearings , also 1 vertical shaft more for load seperation in lower ,then the Konrad ........HOW can the Konrad be stronger, or as strong ???????????

1st. if i would call mercury to test props they would tell me come to lake X !!!
2nd. they will help , and i know for a fact . THEY HELPED ME WITH A 1991 # 4 Big shaft 2 years ago !!!
Also about the parts some are mine some are not and if u read my post then u will see that i said if i don't have it i know who does.
I also know a few people with Cig's that have parts ,,,,,don't know who u are refering to ?!

But anyhow,,,,,what drives do u have on your fountain and what kind of power ? just curious!!

Later

My 311 has TRS drives and my 302 will have aprox. 600hp to start with then I will change blowers and go up from there once I can see how the boat handles. This boat will have Konrads on it.

Cool,,,,so u don't even own Konrads yet.

The marketing u do for them .......they should give u at least 1 set for free !!!!

Other then that ...happy boating.

I am the one with Black Thunder I have 544 hours on it with
3A's no problems with them. Big power needs big drives

DJS

No I do own a pair of them. Unlike you I have actually seen the drive both inside and out and because of that I understand how they came up with their rated HP. According to you unless a drive is built exactly like a 3A it can not handle 800hp.

Ok,,,,,now u are putting words on my tung !!!!!!!

I never said it has to be build like a #3'a or #5 !!!

But how can bravo gears withstand 800 HP ??????

I am willing to learn ,but always tell me i am wrong and can not proof that .
I can proof that a #3'a is rated for 800 !!!!!!

Anyways,,,i am out !!
If u just want to pick on me fine , but a little proof of what u say would be nice ?!

I am not putting words on your "tung". You said "because if a #5 ( 3 a ) is rated @ 800 and has bigger shafts ,gears and bearings , also 1 vertical shaft more for load seperation in lower ,then the Konrad ........HOW can the Konrad be stronger, or as strong ???????????" The reality is you do not know how large the parts are on the inside of this drive. You do not know if they are using higher quality parts or anything like that. You just assume that the drive is not capable of handling what they claim. There are LOTS of aplications out there working fine at the rated HP and have not had any drive failures. Could this drive have failed due to a defective gear or something I guess that is possible, Could it have failed because the owner does not know how to drive, also possible. Does that make all their other drives junk or make them liers about the rated HP? Even #6's blow up does that mean that they are over rated? No one is questioning the quality of the #3,4,5 drive they are great drives, so is the Konrad and unlike the #3,4,5 that are outdated and you can only get used parts, Konrad you can go and buy new and repair with new parts from the factory. Even Joe Tool said that their turn around time was fantastic.

So you asked me why I am such a chearleader for the drives and you got an aswer. What is your dog in this fight. Why do you feel the need to slam a drive manufacturer for a drive that you have never seen, because of one failure? If you want to understand more about what you are spewing out your mouth then why don't you contact Konrad and maybe they can tell you about the gears and shafts so you will know. I know the deal with the gears but it is not up to me to teach you. You said you wanted to learn well that is the best way unless you buy one and take one down yourself.

Lake X is not free to anyone that wants to come down there plus you would have to get your boat there at an expense. Konrad sent their sales rep to this guys location so that they could test props and find out why his boat was not performing as he had hoped. The same sales rep answered his phone on the 4th of July a holiday for most. They repaired his drive at a discount (500 bucks is 500 bucks) a YEAR after the warrantee expired and did so quickly. I think that the customer support and service goes above and beyond most any other manufacturer in this industry.

Let's go back to the original post why did they break and why did it cost me $6000 to repair(not counting shipping cost because no one around here can fix them $350, drive plate $450,tranny reconditioned $600 and engine removal and install$750 =$8150 in repairs). The best part is that the upper gears looked great? so why so much to fix? The answer to the question do I know how to drive and throttle a boat is yes.

If the uppers are fine then I obviously you blew the lower. Could be a bad prop, what you running for a prop? What is the prop height below the hull? I would have some one check all the blades on your prop.
