My next step is to seal the innards with epoxy, and after that it's decking time. BUT, before I put the decks on I wanted to get an idea of where to put the center of gravity? It'd be a lot easier to embed a heavy washer or three in the epoxy before I put the decks on. From what I can gather, it should be at, or just behind the sponsons. Am I correct in that assessment?

Thanks!

Looking good. The CG on my hydro's are all right at the back of the sponsons.

Thanks John. You confirmed what I already thought...

Hey no Problem On the painter's tape tip!!!Its not my Idea...I learned It from the vacu-tug Site!!!Also several other kits Ive built suggested useing that tape to hold thing's.An found It work's very well!!!An now use alot of It.

One thing I did find out however ok..Dont use the manilla colored or the tan masking tape...It leaves a lousy annoying amount of adhesive. In the wood grain.Really a pain to clean up.Also found It tares an doesn't hold near as well as the blue!!!!

Chinewalker, gotta say that was a quick build.

Tidy too---.

I didn't get into the shop last night, but I did print off my 1:8 scale plans at 160% to give me 1:5 scale plans. I laid the GTX 650 on the profile view and it looks pretty good. The boat will measure in at a hair under 24-inches at this scale. Does that sound about right for this motor? I can scale it to pretty much anything, but I figure it'll be somewhere in the 1:4 (28-1/2") to 1:5 (23.8") range

My Miss Elam Brushless I converted from a Nitro Is 27".With a SV 27 Set Up In It.My Miss Bud Conversion Im doing Is the Old style Hull that had the solid straight shaft.It too Is also 27 Inchs.So Im thinking you would be right On with the 1/4 SCALE AT 28"!!!

You know what you have to do with that motor. Strip it down, make a cover that looks like a cyl-block add a couple of tuned pipes. Lets face it we would take a 10 hp Johnson strip it to lighten it re-work the cyl. & pistons bigger carbs and tuned pipes = almost 50hp with lots of speed.

Yeah, I'd actually thought of that - making a dummy cover to make it look a little more scale. It'd be fairly easy to make it look like a Yamato 102 with the orange beak...

1:4 scale it is! Thank you!!

Personaly I think it would look great. One of these days I'll have to dig out a little kneedown pickle fork I built a about 24 years ago. I had a foot from a Allen Sea Fury, drilled it out and ran a shaft with a coupling to it. I had a 540 motor with a 1.5:1 over drive and a 1 inch re-pitched prop. On 10 cells it ran very well, but with a brushless I could get rid of the gears and run Lipos. That would save alot of weight. I had a Ken doll in a bathing suite with his chest cut out over the motor and gear box. The top end of the out board looked like one of the engines we ran, including the megafones.

John - that would be VERY cool to see! I'd actually thought about converting a Sea Fury to electric as I have a spare lower unit housing. It would look pretty good on my 1:8 scale hydro...

I was able to work a bit more on the boat this weekend. Got the inside sealed with West System and installed the foredeck. I used the blue tape idea to help hold the side decking down. Worked great!

The hull is now completely skinned and faired in! I'm calling this stage done! Now to come up with a good looking paint/varnish job. The mahogany bits will be natural, but I will probably paint most of the birch ply areas.... Maybe not.

Next step is to make up some hardware. I remember seeing some dollhouse handles that look pretty close to the grab handles on the transom. The steering wheel and throttle I'll have to fabricate.

John, way back, about 50 years ago, I did it with a 12 HP Champion, running on an alcohol/castor oil mix---.
