Question
Name this boat!

Needing some info on this boat please. My original thought was that it is a Dumas Hot Shot of some sort, however after searching, it seems all the Dumas boats I have found have a full enclosed cockpit area, and do not look like this. Also, any opinions would be welcome as I have yet to run the boat. Thanks!

It should be you naming you're own boats and don't use wine bottle, it will probably break the boat instead.

But since you want us to name her for you, I would want to caller her.

This is a Dumas 3.5 "Hotshot"...!
I use to have one, the top of the cowl is held in place by 4 screws, not much room for this, I used brass inserts to hold the cowl in place.

the flat part forward of the cowl is were I had my ant. that way I didnt have to mess with it when removeing the cover.

you must re-inforce the rear transom, remove it or use a good epoxy resin over the entire rear transom drill your mounting holes and fill the holes in with epoxy resin so water does not soak in the wood!

you can also use alum. plate 1/16 on the rear transom on both sides using epoxy resin & small clamps to hold in place, when done panit& drill and fill holds for mount with epoxy resin.

good luck,

There is a Dumas sticker on the inside toward front part of the boat, if someone hasent painted over it.

and I see you have the tank facing the way it is suppose to be...!
when running all engines the fuel will be pushed to the rear,thats were the clunk is, if it were forward you would run out of fuel even though you still have fuel in the tank.

if you want pic's of how I re-built the rear transom on my hydro let me know, it was done in the same way as my Hotshot tunnel.

You won't find it in any of their current catalogs as it's been out of production for many years. I had one back in 1979-80.

Here's what it looks like, it use to have a engine inboard I gutted it and made ithe radio box in the center, tank to the rear, and the rear transom for a K&B 3.5 outboard engine I added turn fins to help in the turns, I used brass inserts to hold the covers on & to the turn fins.

the boat is not painted, I used Epoxy Resin w/a coloring agent

My transom area looks like this, and I dunno what the black block is for. I can tell you the previous owner said it did cavitate a lot. It seems that the motor should've been mounted straight on the red transom. I am not sure why they used the black block to push it out so far.

My guess is that the engine was bolted to the block at one time, w/o the mount you now have.

as you can see the rear transom is not protected from water, this will get wet & the bolts will be pulled through the wood. I would remove the block, leaving the mount on the engine line it up were the lower end barely touches or maybe a 1/4 to 1/2 inch from the rear, mark this spot on the inside as for you new transom.

if you can wait I'm going to install a motor mount same as yours om my Top Speed 2

OK, you mount is 3/4 of a inch and from the engine hinge plate & lower end is a 1/2 inch.

so from the transom to the rear of you boat there should be from 1/2 to 1 inch before mounting the engine mount.

if you need help with this just ask. I been sick for awhile now and losing my eye sight.
but will try and help you as much as I can.

Take Care,

Here ya go. I did talk to the original owner, and he said that the motor had been moved back due to not being able to get enough movement in the rudder. I think the arms that the control rods hook to on the motor were rubbing or something.

OK, looks like someone modded the rear, also I think the engine is too low.
the prop should line up with the bottom of the sponson were it meets the water line, looking from the rear.

Take a look at this one,

Thanks! I'll read through this, and hopefully my boat will be ready to rumble at our first float fly coming up.
