Question Lone Star dinghy?!?

Y’all may remember Willy the dinghy. He was a 9’ Caribe inflatable RIB that I purchased two or three weeks ago and had a 5hp Nissan on him. He barely planed with one person and was way too slow and way to uncomfortable, so I sold him after 4 days.

So I remembered my father had my grandfathers 12’ aluminum Lone Star boat out at the farm. I plan to bring it back, clean it up and use it for a get around boat. Getting around the lake etc in our home marina. We aren’t cruising so lifting it on davits etc isn’t a problem.

My three questions are:

1. What would you do to refinish this to a shiny aluminum? Wire wheel? Sandblasting? Paint stripper?

2. It will be used in brackish/salt water how do I protect it?

3. Should I go 10hp or 15hp outboard? I don’t want major speed but I’d like to be able to nicely plane and get there with two grown men aboard.

Stats from old Lone Star literature are 11’9”, 98lbs.

I'd sand it with about 100 grit on a random orbital sander where the paint is heaviest, then go up in grit for the rest. I'd spray paint it white after that. I've done that with jon boats for duck hunting a few times, works well. I kind of doubt that you will be able to get it super shiny, but I've never tried to do that as it would spook ducks.


If it's rated for it, I'd put a 15 hp two stroke on it if I could find one. A 10 might work too, but a 15 would be better. Always better to have more HP than you need and not use it too often than not have enough when you need it.

I would love to have it be a shiny aircraft aluminum, but painting is probably more rational.

The old literature says its rated for 7.5... but if you do the modern calculations for boat to motor ratios 15hp is the recommendation.

I know from working on bikes that it's damn near impossible to keep it as shiny aluminum - I'm afraid you'll have to paint. Easiest would be to let it gray. It might look cool gray if you added just a stripe of paint or something along the gunnel

I wouldn't sand the paint off. If you want to scuff the existing paint and paint over it, then lightly sand it. If you want to take it down to bear aluminum, lacquer thinner and a scrub pad will probably be pretty quick without taking away any aluminum.

I'll probably end up painting it off white with a turquoise stripe in the traditional fashion of Lone Star's.

I pick up a boat like that one a few years ago for my beach boat. It lives just above high water on the beach in front of my house. I drag it over the rocks to go get crabs. Yours is in better condition than mine. When I got it, I tried for weeks to get it to stop leaking. I used a couple of tubes of Lexel, but didn't succeed the first year. Late in the fall a storm turned it sideways to the surf and battered the stem quite badly. Then it REALLY leaked, so another whole tube of Lexel went into it along the riveted stem. Hasn't leaked a drop since! Now I will haul it up to the house if a big storm is threatened.
It weighs so little that a 9.9 should get two men up on a plane.

This one was used on a duck hunting lease way down south in the marshes of Louisiana. My grandfather was a duck hunting guide for decades. When he died my father brought it out to the family farm to use in the fish pond. It doesn't leak at all.

There are a few cracks in the chines that I am going to patch with alumiweld rods, and I have to figure out some kind of fitting for the plug in the transom. Have to figure out that whole different metal corrosion thing and how to prevent it. Other than that it floats and is completely usable.

I'd like to maybe build a small deck over the bow out of wood, and maybe put a remote steering console on it (a-la boston whaler style).

The literature says that it only weighs 98lbs, but that's really old advertisement literature.

I just need it to get on plane and GO. That inflatable RIB that I had got up on plane but barely stayed there. I want it to feel securely on plane.

You speedster! Where`s Art`s speedboat icon when you need it.
Would you bother painting the bottom? It`s just going to get sanded regularly,like every time you beach it.

Yes, I'm going to put a bottom job on it. It's going to be stored floating and tied up to my big boat.

We don't have beaches in our immediate area. We're inland on Galveston bay.

I think you`ll need an aluminum specific a/f paint, ie no copper in it.

I think I've secured a 1984 Johnson 9.9 for about $450 including shipping to me.

The fun part is that the 9.9 is the exact same engine as the 15 except for the carburetor. So a carb swap should give me more hp if I end up needing it.

I think it looks like a very clean engine.

I have a 6 HP mercury from the 1980s. I believe there were 3 HP ranges for that motor (6, 8 and 9.9). The difference between the motors I'm told, is the decal on the cover and for the smaller engines there is a restrictor plate (limits air flow) between the carburetor and the motor. I'm told that removing the plate or drilling it out, changes the HP. Maybe you will get that lucky. Mine is still a 6 HP.....but you never know.

Perfect engine for that boat. Is that block the same as the 6hp and 8hp or the same as the 15hp? I can't remember, and Ted may be right, it might not be able to be souped up to 15hp. If it can, it seems like a no brainer.


Funny, my buddy had a very similar boat that he got from his grandfather. We used it to hunt in Louisiana, in Delta Wildlife refuge, south of Venice. I think it had a 6hp on it, it would barely plane with two of us in it, but not with a bunch of decoys, two guys, a dog, guns etc. We shot a pile of ducks out of it.

Old 6-8hp 2 stroke is best for these aluminum skiffs IMO.
Very good boats. The most popular boat in Alaska.

toocoys,
May already been mentioned but Interlux has a how to section on their website and however brand specific it’s excellent advice/guidance.
I followed their guide and put AF on a 16’ Crestliner. Turned ot great but was a lot of coats and work. But one can see howmany coats of what kind of primer and what is best for topcoating ect.

Truck trailer aluminum cleaner. Zep. Phosphoric & sulfuric acid - so take appropriate precautions. This will also get into any crevasse corrosion and arrest that process. If you have any enclosed flotation foam and flood the hull to clean it out you should also neutralise with ammonia until slightly basic ~ pH 9 is good. Periodic bilge treatment with baking soda will prevent future acidification.

Stats from old Lone Star literature are 119, 98lbs.

Years ago I used to fly and maintain seaplanes in salt water! After you sand all the paint off get some aluminum brightener and wash the hull with that. When dry..wipe it down with a clean rag and lawyer thinner! Prime the bare aluminum with zinc xhromste primer. It's a funky yellow/green color. Give it a pretty healthy coat! When dry, give it a very light sanding with 220 paper... Wipe again with a dclesn cloth dampened in laquer thinner...don't sort the rag as it will remove the primer. Then paint the color of your choice. I recently used Rust-Oleum Top Side Paint that I purchased at Hone Depot. On an old Boston Whalers. I rolled and tipped it. It came out with a mirror finish. Two weeks later, when it completely hardened, I rubbed it out using s fine rubbing compound..
