do a search there are several long threads about it

Re: props in or out??
 

I don't know about speed but, my Top Gun turns out and it is a breese to dock. I had a Fountain that turn in and you really had to fight to get it docked. Not sure if it would have the same effect on the Cig but if it did I wouldn't change for a little more speed.

Re: props in or out??
 

Usually In = Faster, but worse handling at low speed. Out = Slower, but better manners.

Re: props in or out??
 

Mine run in and I agree with everyone and there comments. I have a 35 Cafe'.

Re: props in or out??
 

Can't speak first hand for the effects on a Cig but on my old Formula, they were originally spinning out. The boat handled beautifully, ran great and I could dock it anywhere. In the endless quest for speed :cool: I changed the rotation to inward. I did it at the same time I made many other modifications so I can't tell you exactly how much speed it netted. What I can tell you is it tended to porpoise more at the same trim angles (trying to hold the bow higher I suppose) and it was an absolute BEAR to dock. If you're not looking to wring the last mph out of your rig, leave them spinning out.

Re: props in or out??
 

Similar experience with the porpoising/docking.

Re: props in or out??
 

mine docks real easy :cool:

Re: props in or out??
 

Tried it Saturday the 24th on a heavy straight bottom Top Gun. 3 Mph Faster turning in. But the docking is a challenge. I noticed no difference in the midrange with porposing, only more power needed at the docks to make it move.

Re: props in or out??
 

Good info and exactly what I've found with my heavy old girl.

..But I do enjoy the free speed!!! :evilb: :D

Good talking with you in KW Jim,

Re: props in or out??
 

Boy Kurt, if thats true I really lost speed. I went from turning out and running 82 consistantly (82.6 on gps best) with the TRS with nose cones, to running 80.4 and turning in (and they are correct docks like crap) with the Konrad 540's .

Did you pick up any speed by switching to the cresent lowers?

Re: props in or out??
 

I lost speed with the cresent lowers, but still run them. Konrad made me a set of welded on cresents that were 2-3 MPH faster. When they sent me the newer design the old ones were destroyed. I tried to get them back,

Re: props in or out??
 

Ours turn out (3a's) on our Gun. Great around the docks.

Turning in brings the bow up when airing out...At least with the Tigers. Prob. same with anything though.

How hard is it to swap it from out to in??

Re: props in or out??
 

Everything else is the same, no porposing, boat still feels like its glued in the water.

Zero, did you lose speed going from TRS to Konrad though?

Re: props in or out??
 

Yes, 2-3 Mph. Must be the bigger gears, and all of the oil they turn in. I tried 1.7" shorter, 1" shorter, and the X that the TRS was. I went back with the Same TRS X deminsion. The Midrange cruise is better with the longer drive by 4 MPH. I use mine at Cruise (55 MPH) for long distances. 150-300 mile runs.
To swap rotation on a transmission boat just swap the drives from side to side. A bravo boat is easier, just swap the props and put the shifters in reverse to go forward. Becareful when returning to the dock.

Re: props in or out??
 

The Konrads have 110 hours and have been perfect. The lowers in the picture are the welded ones Konrad produced first. No bondo or filler.

Sweet TG ZP, Rick pm Mr. Cig. from chicago he did the full konrad swap this summer to his 84 Flat Deck, and has been really happy. Steve

Re: props in or out??
 

86Rette,

As, you might already know, my Top Gun was the first Cigarette to be converted from Merc TRS to Konrad's and I've got to say I'm a bit puzzled by your findings.

When we first converted my boat, we installed the 1.6" spacers as to duplicate the TRS propshaft hight and the same pitch three blade propellers. (When I was running TRS drives, lower pinion gear life was pretty short with 4 blades) With the increased viscous drag and the much larger gears, bearings and shafts we actually expected to see a decrease in top speed.

When we did our first sea trial, we were pleasantly surprised that we did not lose any speed at all. This was attributed to the superior hydrodynamics of the standard Konrad lower unit over the antiquated TRS lower (no cones). (Konrad's HP lower was not available at this time)

Our next step was to remove the spacers. This put us 1.68" higher than the TRS installation. We instantly picked up 2.5 mph. No other mods. We then ran several sets of 4 blade props and gained another 2.5 mph.

What I have found over the past two years is that no two Cigarette's are the same. They each react a bit differently to the swap and need to be set up for the owners boating style.

Re: props in or out??
 

Biggus,Zero thank you for your input. After reading your threads I am convinced my speed loss is due to excessive drive height. 4 years ago we replaced the transom board and raised the X demension 1.75'' . We only put a 1'' spacer in the Konrads. I know this seems like splitting hairs but that .68'' could be part of the problem. Rick

Re: props in or out??
 

Kurt, dont get me wrong, I am totally pleased with the Konrads. My boat has a high X from the factory. The CMIs had to be clearanced into the hatch because the engines are high. I tried shorter with P5Xs, but longer with Bravo 1s have been the best. See you in Miami for the show

Re: props in or out??
 

thanks everyone. great info...considering my boat alreadty has a porpoising problem i think il keep em how tehy are :D
