I love the cowl you made up for your boat.
I have just picked up 2 Bullitt kits and was thinking of doing something similar, can you tell me where or how you made
these extra bits I tried to click on the photo's but they won't enlarge. I'm thinking of one with a exposed motor and the other similar to yours
as I have a rocket tboat done in the std way and really love her.

any tips or hints will be greatly apreciated.

jvdd,
Thank you for the nice words.. The BULLITT was a great kit all peices went together nicely.You can go to my photobucket page and see tons of pics of build. For cowl, i used the cowl that came with kit and after putting it on the top deck and securing,i got out the dremel tool and cut from just fore of the cockpit across top down the sides (but left 1/4" or so alog deck) then used blue foam board to shape rear section. For the front I cut down at new windshield line and glued the old cockpit part inside,cut a hole in top for scoop(needs to be pretty big to flow lots of air) and also shaped the scoop out of blue foam... then using 30min epoxy layered glass cloth first layer on back inside between foam and old cowl to be sure it was firmly attached to cowl,then layered several cloth layers to match thickness of stock cowl. The rudder is just thin ply glued into foam and glassed up to it to make the fillett.. Then I just finish resined the ply rudder when I resined the whole cowl. I made all the scoops by shaping blue foam and covering with plastic so I could pull foam out after glas and epoxy had cured. I left the foam in top scoop but if I were to do it again I would make the scoop,remove the foam and attach to top..the windshield is a old funtana airplane canopy cut down to fit..after cowl cured and was finish resined i cut the foam block out to save weight..I needed to add a baffle to top scoop as the head needed more air directed over it to keep cool. I had to add a lb. of lead to nose,to ballance(c/g is at rear of sponsons),I WOULD SUGGEST TO put weight in front of sponsons on bottom to keep weight low split the weight and add slightly more in right side go with less than a pound then you can add more to nose after all gear is installed. Hope this helps I will try to post a few more detailed pics of inside cowl also so you can see that. Feel free to ask mpre questions!!

P.S. the scoops on back will be necessary to help cool inside of hull,and I would consider a couple more in front as it gets pretty warm in there.. I used the X-FORCE engine and ZIPPKITS pipe and hardware,only addition was a propblast pickup as head was not getting the water it needed and I doubled the lines from rudder to the exhaust manifold. Gizmo makes a exhaust manifold that bolts to cyl. and flange bolts are at an angle so you can remove easier.. I have to pull pipe and engine to change o-rings...pain in the buttBe sure to sharpen turn fin it took a while to get it thinned down and sharp.but well worth the time.I have a 500ml iv bag and can run close to 20min... the stock prop Joe gives you with ultimate hardware combo pushes it pretty good!! hitting around 50+ now...
