I thought that I might like that boat until I saw the green engine.

Looking mean.. key now is sorting out how it sits in the water with a ton of gas and water in it.. did you think about smaller twin diesel motors in it at all?
If you've heard about it, you've probably missed it...

You mean those 4000hr+ Ivecos that run like new and still don't use oil or smoke Wink. I have a couple of used green engines with much lower hours you can buy straight after I sell you that funny looking bridge LOL.

That's not one of those horrible 435hp D6's (aka Volvo retirement fund planning) is it? 5.5l & 435hp = lot's of trips to the shop. Really, some of the marine diesel manufacturers should be hung for the irresponsible way they pull hp out of small displacement engines and then let people think they are buying engines that will last for years like the older diesels did. If it is a 435 D6 can I suggest that you under-prop it a little to deload the engine slightly.

Honestly, I like what you are doing with the hull. Building in alloy, I probably would have gone for a finer entry for improved ride myself, but other than that I reckon that what you are building is going to look great and I hope it goes really well for you. Like you I really like those classic Carolina lines.

hey nar i did not look into twins as it would take up to much cockpit width and add cost 

its the 370 hp motor not the 400hp. I looked long and hard at Ivecos and the issues i had was they produce to much torque for a leg to handle and the only leg that could/should handle there torque is the new Konrad 680 which i think there are about 4 of in nz of which 2 that i know of have been returned to konrad having **** themselves. 
Then you also have to run a separate gear box and exhaust which can be an advantage in some respects but also more cost / install and more to go wrong from different manufactures who could all try blame each other if you had issues. The issue with ivecos is they are not the most economical motors using about 9lph compared to volvos 5 lhp at trolling. and for a motor package with leg box and twin stations was about 120k plus install 

I like how volvo do everything from controls to leg to motor . There are other manufactures who offer this like  yanmar but they will not stand by there leg at anything over 4.5 ton which raises alarms if they have that little faith in it and i have heard mixed reports about the v8. vw/mercury is the other option but these motors I'm pretty sure are made in China and if you know where to look are available for around 20k US and then marry it up to a bravo leg but from reviews i have read the volvo ****s all over them in fuel consumption and speed and noise and kg per hp that you would defiantly loose sleep over.

So that is why i went for volvo in this size motor there is not many options and volvo have been dominating this hp bracket for a long time now so must know a thing or two 

also the design has quite a bit more plum bow and finer entry than the last 3d i put up i think you will like itThumbs Up

Will be interesting to see if you get your 5lph from the D6. My Ivecos are 7.5lph at 8 - 8.5knts and around 6lph if I keep it back to 7.5 - 8knts. My limited experience with a new D6 we installed a few years back didn't suggest to me that it was any more economical. Might get a small gain from the trimmable leg vs an angled prop, but 5lph at ~8knts would be a very good figure.

Agree that the Ivecos aren't any good for a leg with the high torque and I wouldn't have done the Konrad thing either. In that 370hp range the D6 is probably the tidiest package as you say, but buying Volvo's is what I have found to be an expensive long term exercise. One good thing though is that once you build up your network of alternative parts suppliers and overseas contacts you can avoid some of  the rape and pillage that is usually associated with buying Volvo parts in NZ. If you do all your servicing through a Volvo dealer you probably won't like the numbers very much.

Did you work out how far off your trolling speed the supercharger kicks in? On our KAD32 boat you would have to be on the superchargers to troll at 8 knts and I can't see you getting your fuel numbers with the supercharger running full time. If you are on the cusp of the supercharger at trolling speed you are going to hate it as the charger kicks in every time you surf down a wave, meaning throttle changes and stuffing around to get back to the correct speed again. Stupid bloody system really. Just finished installing some supercharger cutout switches in a boat yesterday for exactly that reason. Couldn't run the thing at slow speeds in big seas without either going so slow that the boat was hard to control or so fast that the superchargers kicked in on every 2nd wave and slammed the boat into the next wave before you could pull the throttle back.

Why did you decide on a leg? Do you have shallow water requirements, going on a trailer, or is it to do with the hull layout? Probably would have opted for a shaft in a tunnel myself if possible. The later V drives are much improved on the earlier ones if you still want the engine under the cockpit.

I like the lines, what's the beam?
 
Heck Tagit my volvo is so old now and they made so many parts are cheap and plenty around used.
 
I havn't needed any yet to speak of though.
 
Fingers crossed.
 
The smoke keeps the bugs away.
 
I am not keen on any of the new stuff.
 
I just changed my little truck and searched till I found a mint 97 non turbo with 36000ks.
 
I plan to keep it as long as I can and just hold everyone up on hills....and flat.
 
Good luck with the build keep the updates coming Spectrum.

Looking good are you working on it full time ? Must be a buzz building something like that .
Interesting talk about engines will follow it closely .
Bloke down here has a big new 11 metre extreme and it s got vw s in it , heard it's been towed home 2 - 3 times already which hardly inspires confidence , you wouldn't want to take it to the king bank that's for sure.

Those VW's are a very wide motor too.
There are one or two Southern Sport's around with them in and there ain't much room to get past the engine box on those

I was working on it full time for the first few months but have had to go back to work last month as my bank account seamed to have a very large hole open up in it when this project started LOL so now i am working on it 1 week out of 4 and have a mate helping after hours. 

yea the superchargers kicking in may be a issue but i will see how it goes when the boat is in the water may put a switch in. The boat is trailerable so a leg was the best option especial in Mangawhai at low tide . it is 9.4m x 2.9m beam. Parts online are very cheap a full service only cost 250 plus oil.

You are right at my perfect sized boat there.
 
Mine is 8.2 hull by 2.8 (9m overall)
 
I am happy but could use a table and galley.
 
I reckon 9 x 3 would do the trick if I was building so interested in your layout etc as it develops.
 
I always liked the Genises profish which is about that size and still single engine sedan.

That definitely shows that you aren't getting your servicing done in central Auckland Shift+R improves the quality of this image. Shift+A improves the quality of all images on this page.. The filters and impeller alone would probably get close to that, let alone the labour and coffee breaks.
