I just bought a 40 " fiberglasshull and I was wondering what would be a good setup for it like engine to hradware. Any help would be great

soundguykaraoke50

your going to need to give us more info than this

JLITZ3

Well i don't know to much about boats other than it's a deep vee and it looks like it might have had a motor in it once before because the motor mount is still installed. I will try and post a picture. Thanks

Hesco Racing

Looks like a nitro boat from the looks of that mount. Give some sizes.

JLITZ3

It was listed as a 40 one half inch deepvee boat. Thats all the info that I have. I wish I had more, thanks anyway.

soundguykaraoke50

that was probably a .67 motor in there.this would be a chalange to go gas as the size of the boat might be a bit to small.i would go to warehouse hobbies site.they have a builders specal for this type of project.$299 that comes with everything need to do a conversion.great deal plus like 20-25 to ship here to the balto area

soundguykaraoke50

soundguykaraoke50

they are very eazy to deal with.i buy parts often from them.there are other ways to go.but this is the most complete package thats out there.the 13 inch beam is a good thing with this size boat.good luck ,

Thanks for all of your help.Funny thing is this I am an airplane guy so I don't know squat about boats other than it looked like it was worth 10.50 on ebay and with your help with the gas conversion this should be kind of cool low budget boat. I don't care if it go's 10 MPH it will still be fun. I saw the thread on people buying 60 mph plus boats and how crazy they are for believing that crap. I can't thankyou enough for your help I will keep ya posted . This should be a screem....LMAO

What width are the rails ? for gas they need to be 5" ,you might be best keeping it nitro if yours are narrower.

Looks like the rails are 5" to me. You'll just need to lose the nitro mounts. If the nitro mounts are glassed in, you can use a heat gun and get them out. You just have to be careful that you don't delaminate the hull layup.

If the stringers aren't 5 in, they can be removed and redone. I have taken out and moved stringers before[:@], it's a pain in the neck but doeable.

45deepvee

stock 260 would go in there fine. top secret stinger, offset a single rudder, single trim tabs, turn fin. should be a good running boat.

I can't say thanks enough for all of your help guys, I am doing this for my son and I and with all of you guys helping me i am sure we can get this boat going. thanks again and I will keep you updated as soon as the seller sends me this hull. I will take some pictures and ask a thousand questions so please forgive me for my lack of knowledge. Again many thanks to all of you.

JLITZ3

Let me start by asking where I might find some instruction as to motor angle and setup of propshaft and rudder. I was loking at the different lenths of rudder shafts and strut sizes every other question that may arise. Thanks

45deepvee

with that boat, if you use a stinger drive which is a surface drive the shaft wil come out the very botom of the hull. right at the point in the bottom of the boat. just make sure the shaft comes out of the motor straight and makes a gradual turn to straighten back out coming through the transom straight. there really isnt any set engine angle .

JLITZ3

ok thats sounds great also when you get the hardware dose it explain howfar the tube comes out of the back and where to end it at the motor? I know this sounds nuts but I really am a Newbie sorry for crazy questions. thanks

My Feedback: (1)

Some pic's, hope it helps . you want to leave about 1/8 to 1/4 inch from prop to strut too !
The felx shaft will strink under power and that the reason for this space

With your motor you do want a 30-33% center of gravity. Witch on your boat being 40 inches should be about 13.5 inches from the transom to center of spark plug. Then put on your hardware and mount the motor. And you can redo the stringers to fit the motor in. Just be sure to glass them in. You can use wood like poplar soft enough to work with but solid enough to hold a motor.

Here is a link that will help you with set up info. You can't use the mesurements they have not the same lenth boat.

Once again BIG Thanks Guys.. for all of your help.

Hey! Good luck on the build! It looks to me like a Dumas 41 Scarab. Nick "sickmodelpowerboats" is rebuilding the same boat now. The first one he lost to a radio glitch and a very hard dock. He has a thread going here in the "Gas" section.

I am converting a Dumas 55" Scarab 38KV from nitro to gas now. Fun, but double the work tearing into the old nitro stuff, refabricating, then rebuilding to gas. Patience!

Anyways, as you build, install all your parts radio box, strut, rudder, trim tabs, fuel tank ( half full with water) then balance the boat at desired CG place (30-33%) as noted before and rest the motor and exhaust pipe until it balances at intended measurement. Whallah!!!! You have the correct CG and motor placement.

This is the process I have been told many,many times over. I hope it helps!

Have fun picking the hardware and getting it built! Welcome to gas rc boats!!!

Well I just received the boat today and man is this thing battered but for $10.50 I guess I can't complain. I noticed that the hull has two openings where maybe at some point two different shafts were used. Since there is 5 inches between the rails I am hoping gas will be the way to go instead of nitro. I guess since Warehouse hobbies have a deal where you can get the engine an hardware and fuel tank all at one price for $299.00 this might be the way to go. I think just starting out I don't want to put a bunch of money in a hull like this as I have been looking at some other hulls that are just crazy and I would rather put the money in somthing like that. However this year will be a learning year and I do have alot to learn. Thanks again guys and any imput at any time is great so don't be shy jump in at anytime and give me suggestions

I'm sorry to say this, but I think your going to have trouble getting that large air cooled motor inside of that hull. The length is OK, (could be a bit longer) but it looks too shallow to me. Got a gas weed eater? If so take a look at it and see what it would look like if you stuffed the motor inside of that hull.

A water cooled Zenoah is going to be smaller and sit lower inside of that boat, but it is still going to be a tight fit. You may want to clean the hull up a bit and put it back on E-bay. You will be much happier with a hull that is designed for a gas engine.

Just my opinion,

Dale P.
