Default Is it worth it???

My teacher brought this in today. Its a dumas deep V 40 It is 32inches long and 11inches wide. It has a k&b 40. The exhaust goes straight up out of two stacks. The only thing I don't understand is there are two holes on the exhaust flange. Why is that??? The carb is black so I thought maybe it had exhaust throttle at one time The radios are futaba and are old shool!!!!!!!!!!!!! They are a tan color. One is a two channel and the other for a plane. Also it came with a bunch of engines. A O.S. .40 plane engine, and about 2 others, there are also some like .049. Do you think it is worth $75.00????

Something to remember ....
The price one pays for an item , all depends on whether or not , that person thinks it was worth it .
Take some of those OLD engines ( nitros ) that sell on EBAY .... to me, those things are not worth a dime , yet they sell in the hundreds . ( atwood's )
Also , if it DID have the exahust throttle , there was a LOT of those that "screamed" a LOT faster than the oridinary , throttled carb only version .
Nice part about the K&B , is that you can STILL get parts ... ( talking main engine components ) and if you can not get the original , you CAN get swappable , replacement parts .
Now , if you add the parts up seperately , and are a little more specific on condition and which models , then YES , he definately got his $75.00 worth .
Shoot , certain 049's sell alone for $20.00 , and up .
Then the OS 40 , pending on condition , could also sell upwards to around $40.00
Then you have them "old school" radios .... there ARE collectors out there that would buy that and they usually would sell for around $15.00 up for them each .
Then the hull .... again , pending on condition , sell for around $25.00 up
Then you have the hardware on the hull .... and of course the K&B 40 ( assuming you are referring to the K&B marine engine , and not an airplane engine that has a KOOL KLAMP slung onto it ) , these will also sell , and sell for around $45.00 up , again pending on condition .
Soooo ..... add up the numbers ....

Now , the part where you said ---

The exhaust goes straight up out of two stacks. The only thing I don't understand is there are two holes on the exhaust flange
Is this an airplane engine ? sounds like it

It has a water cooled head though, I took the head off and the piston is shaped really wierd. It has a splash type guard by the intake port. Here is the carb that is on it. What do I do about the holes in the exhaust???

Wow, you are talking vintage there. The engine sounds like the K&B .40 Torpedo that was popular back in the `70's. Does the carb have linkage that runs to a plate that swivels on the exhaust? I haven't seen one of those pistos in a long time. A LHS had one in their close-out bin. The Futaba came from the same era.
$75.00? Not really that bad. The hull is the same one that Dumas has been selling for eons. A 'glas hull would be a better buy that the wood version.

Check out this site on your engine. <www.mecoa.com/kb/>Splashs guard was an option. Perry carbs were installed on really old models. Hope this helps. Sorry, can't help with the exhaust sounds cool though.

Think we need to see pics of the exhuast. Might be the old canister type exhaust mufflers that have 2 holes.. Here's a pic of the new 3.5 OB's with the can muffler, older K&B inboards also used these.



If the exhausts looks like that, don't plug them up...
