A quick test to see if everything fits and also to make a quick template for the motor mounts

It’s kind of a tight fit but it will work fine :)

Finally a "quick and dirty" template for the motor mounts :D

Wow you guys sure are making great progress and not wasting any time!!

ragman 10-31-2013 08:32 AM

You’re to kind; all of these pics are taken over a couple of years. So we are not making that good progress as it is a hobby project. So most of the time there’s just a few hours after work here and there we have time to put it together.

The plan is to be ready for launch next summer :)

Moving the boat from our painting facilities to the workshop on a nice wintery day :) Kind of strange that I miss the winter season ;)

Today there has been some work with the exhaust system. A lot of measuring and a lot of thinking to try to come up with something that’s a little bit different than usual :)

The beginning of the new exhaust ;)

Very good stuff i envy your shop.

VoodooRob 11-05-2013 01:34 PM

I was just looking at your photos, you are really knocking this project out with some high end, one-off parts. Excellent machining on the aluminum. Just an FYI, one of your last pics is of your custom exhaust and the rear of the engine showing the crank with the flywheel bolts in it. Make sure to put extra, extra red Loctite on the flywheel bolts on Viper engines. The threads are tapped all the way thru ( you can see in the pan thru them) and oil will leak pass the bolt threads causing you problems. Just trying to help if you didn't know this, obviously your mechanical abilities are far above average.

Wow! Thanks for those to kind comments! You made us blush over here ;)
I am aware of that issue with the bolts but big thanks for the heads up. Next time it’s maybe something that we overlooked. Thanks for showing interest. :)

So the next step is to build some type of vents. I have not decided on the final look yet.

I havent done it yet but off course could we do some work if it seams like we could be a good choice for that particular job :)

Any update pics??

ragman 11-21-2013 08:43 AM

I haven’t had that much time over for the boat lately. For the moment we are all working with the winterizing of our customer boats. So I will probably have some updates during December when everything calms down here on my workplace :)

Clunk 11-22-2013 03:57 AM

Very impressive. I like the colors you're putting down. Lookin forward to more updates.

wow that is going to be one fast boat. it looks sick man. I'm loving the colors you have going on. what kind of fabric did you use on the seats? almost looks like a suede.

This said enough! http://www.offshoreonly.com/forums/c...cing-pics.html
You answered all my questions thoughts and ideas! Sending you a pm. We have 2 IMP 25.5's (My dad and I have matching Eleganza's). I must say this has blown me away very nice work!

VoodooRob 12-13-2013 05:30 PM

Great choices, exhaust is a different approach like where your going with it. Looking forward to some youtube videos of the boat running soon.

KRAUSMOTORSPORTS 12-13-2013 05:41 PM

Ragman, I would like to know what your ideas are on top speed? And how straight is the hull itself…. I don't know how the 31's differ from our 25.5 but ours both being 1987's our hulls are completely different. Mine which is very light compared to dads which he had to straighten. Even in the upper 70's It ran very wet up front but was also due to his higher x-dimention and lack of trim…. we are both still on single TRSs and Mine ran high up front with a lower X-dimention and much straighter both on Spinelli 4 blades. I would love to know more about your build.. Send me a email please. I don't want to clutter up your awesome thread with me :asskiss: all your progress. haha

Thanks for your too kind comments :)

I dont really have an idea on how fast she will go :) When the previous owner had it running (I bought it with broken engines) it did 75mph on the GPS with 320 EFI´s and TRS :)
One of the previous owners here in scandinavia bought it as a raceboat (as you probably already know) it was called Cheap Thrills.
Robba (Previous owner) started to remove all of the wood all the way thru the hull and replaced it with Divinycell core material. That made some possitive effects on the total weight. So when i started out with the boat it weighed 2700 kg which i think is around 5900 lbs :) So it doesnt weigh that much. I have also done som weight saving mods so I have saved another 200 kg so today a total weight is around 5500 lbs :)

About the hull i have only made the bottom straight before the paintjob was done so today its as straight it can be :)

If i dont reach the topspeed I am after I have a friend who bought the Activator 27 molds. So if that happens i have to flirt with him to buy a Activator 27 bottom to my IMP ;) :D

KRAUSMOTORSPORTS 12-15-2013 03:47 PM

5500 wow that's pretty light. Just before I started the "lightening" of mine It was around the 6k Mark and I'm 5' shorter than yours. Although my Dad's is even heavier. His hull is thicker and more front end heavy for sure. Activator 27 Molds would be interesting. I was thinking the Active Thunder Mold. Doubt it's possible but the IMP have always resemble them is some ways as far as decks. Since I'm in the chesapeake and a 32' Is considered the ideal length I would even Consider selling mine to get a 310 IMP
