Konrad is a very strong drive but Ive heard (and experienced) some significant speed losses.

Bam as I recal said only a 2 or 3 MPH loss (would not call that significant). However the guy used his boat trouble free for the entire year were he was blowing drives all the time with the bravo's. That was out of the box set up. Not sure if they got the speed back with testing. Konrad also now offers an even shorter lower that could see even better results as far as speed is concerned.

is there allot of re griggin for conrads? I have a 42 staggered lightning would be willing in the future to go with that drive if I would not have to have all the head ache of putting in trans and all the other stuff!

You MUSt put a trany in for the Konrads. You'll also need; Trany coolers, water pick ups, and in your case a new starb. drive shaft shield. In a staggard 42 I would put the trany's in the boat. Would be relativly easy and clean job. What power are you running and how far forward are your motors now?

I just realized we are hijacking an Arneson thread. Why don't you post this ? up in a new thread.

Not looking to lose any MPH, hard enough keeping up on poker runs allready.

If I was looking to do engine mods, then a slight loss from the drives would be made up by the mods, but for the added expense, it seems like the arnesons would accomplish both the durability, and potentially increased top speed for less than the konrads, and mods.

Tough choices, not factoring in resale, might get a second boat, but not looking to sell the Nordic in the near future. Just looking to be as fast, safe, and dependable as posible.

So we got the Top Gun over the 100+ mark yesterday, ( post 1 of 97)
It's been a great deal of work planing and prop testing but CONGRATULATIONS to GotTime, we ran 108.6 with out and playing around, no wind, and tabs down at 6000 rpms. The props were 18 35's and the motors are still on the chips, so we could potentially see higher #'s with the proper props and some adjusting on the tabs and drives depths. The boat has a set of 1000hp 572ci with 1471 blowers and is a 1996 Top Gun FULL CABIN hull. I'll post a link to a quick video of us running.

Dude, u-need if I can I will God speed for U---J --:eek:

Have you put a call into Nordic yet? That would have been my first call. Are there any Nordics they know of with a surface drive? Have they built any? What are their thoughts on your hull and an arnison? Just a few questions I'd ask.

SAince this thread is 6 months old I hope BT wont mind if I take it into another direction.

Formula built a bunch of boats w Kaama drives in the mid to late 80s.
Does anyone know how these worked? say compared to stock (TRS) drives for top speed and handling?

Thanks
