Just thought I'd share my project. My 1964 16' Larson All American has the original 85hp Mercury 850 and it starts up everytime. Its already a good 'ol boat that just needs a new transom and some TLC.

This will be my first boat restore so I'm sure I'll have plenty of questions along the way. It was my Grandpa's boat he bought it from the original owner in 1970.

Let me know what you think!

Welcome to iBoats.

Absolutely OUTSTANDING. Similar to my old 62 Flamingo. Fortunately my transom is good to go bu the motor and interior were shot. I am going to get started in a couple of weeks. I will be keeping tabs on your rebuild. Do your Grandpa proud and bring the old girl back to life.


Good Luck

Well I had some time to take off the motor yesterday to get a better look at the transom. Looks like there will be plenty of glass work to do.

There are a few big cracks, the journey from Minnesota probably didn't do it any favors.

No reason to waste money on an engine stand when you have pallets... :)

First look at the transom minus trim and motor

The floor seems really solid so I'm going to avoid replacing the stringers and flooring if I can. The factory vinyl covering for the floor is brittle and damaged. Is there anywhere to find that material? I would love to avoid replacing it with carpet.

I'm going to be completely redoing the trailer as well so if anyone has suggestions to be sure weight is distributed correctly, transom supports, etc. It would be much appreciated!

Re: 1964 Larson 16' All American Project

Give us some pics to show us what you're lookin at. If the floor has soft spots then the superstructure underneath(stringers) are for sure rotten. They will definitely need to be replaced. If you want grandpa to be proud and you want to do it right....
Then do it right and tear it all out and restore it so it will last for your grandkids to use and they WON"T have to restore it.
:D

Re: 1964 Larson 16' All American Project

I'm pretty sure the floor doesn't need replacing. It is very solid and I haven't found any soft spots so far. I'm planning on separating the top from the hull sometime this week and I'll be able to post some pictures of the floor with all of the interior stripped out.

Re: 1964 Larson 16' All American Project

After removing hundreds of screws and rivets I got the rub rail off only to find a ton of staples and epoxy holding the cap on.

Its been in the mid 90's this week and sweating 'till you're soaked is a necessity. Finally after two afternoons with my friends hammer, pliers, and pry bar I got the cap separated from the hull. YAY!

Ive been thinking about how I'm going to reattach the cap. Since I don't have an industrial stapler my fist thought is to use pop rivets. Any suggestions?

Here is the fist look at the transom, it was getting dark so the picture is not very good. The inside layer of fiberglass is very thin and almost seems more like tar paper than fiberglass.

Re: 1964 Larson 16' All American Project

Good Job on the cap removal.
To put it back you can use pop rivets or Stainless Screws. I would use the Rivets.
Transom sure needed replacing. Inner skins are very thin some times. No worries. Cut i all out, all the way to the outer skin from side to side and all the way to the bottom. Get it nice and clean and sanded smooth. You will be laminating Glass over the new wood which will give you a thicker and better inner skin in the long run.

Keep up the sweatin and Buy more BEER !!!!:D

Re: 1964 Larson 16' All American Project

We had plenty of beer so no worries there :D

I was planning on going with seacast because it seemed so much easier than plywood but my boat is pretty straight forward so I think the time and effort would be about the same either way I go.

Ive seen discussion on the type of plywood used. Do I need to special order something or can I just go to Lowes/Home Depot and grab a sheet of marine grade plywood?

Re: 1964 Larson 16' All American Project

You don't need marine grade unless you just want to. Ext. Grade and Marine use the same glue only difference is marine grade has no voids in the plys. Most of the guys on here use ext. grade give it two coats of resin and encase it in glass and call it good. that will las at least 20+ years.

Re: 1964 Larson 16' All American Project

I remember trying to determine the exact year of my boat and finding a pdf listing my Mercury only being available in black on the '64 (normally the 85hp came in white). That said my serial# starts with 101 if I remember correctly so my guess is yours is likely a later model.

Re: 1964 Larson 16' All American Project

Just thought I would jump in and express my enthusiasm for your project. The old Larson's have really nice lines not found on other boats. I really wish I had an outboard rather than my 120hp four cylinder. It purrs like a kitten but the outdrive (OMC) is for sure to be afraid of! Anyway, I will be watching your thread and don't get discouraged. I found mine in a barn ready and running for $750. Paint was completely shot but interior was mint and the floor like concrete!!!

I am currently replacing the coils in the lower unit and look forward to a summer on the lake with my kids.

Re: 1964 Larson 16' All American Project

Well I finally got back at it yesterday. My Grandma passed away last fall so unfortunately the project wasn't done in time for her to see it. I've decided to set a lofty goal to help motivate me to get it done. I'm gonna work my butt off on it so it's lake-worthy by May.

It will be nice to have it ready for a full season and since its already warm enough to be out on the water I gotta get a move on!

After pulling staples, drilling rivets, prying and dremeling the thing apart I finally got the boat cap completely off.

The transom is completely rotten but I already knew that, it's why I started the project in the first place.
5551205487_66fdfb36bd.jpg


So now I'm trying to figure out the best way to cut as close as I can to the hull without damaging it. The wood on the ends is in a lot better shape than all that mush in the middle which means it's a lot more stubborn and needs to be cut out.

The floor is really solid but I did find one little soft spot that I'm planning on cutting into so I can assess the damage. I'm going to make a cardboard template of the floor first, I have a feeling I'll decide to rip it up anyway.

The last news is probably what I'm most excited about. I made a deal with one of my Dad's friends to paint my boat in exchange for a website for his hot rod shop. This is really exciting because I was planning on trying out the roll-on method and I didn't have much confidence in the potential results.

By the way I love the red that looks great! It's nice to see pictures of other All American's out there. Yours is the only one that I've seen with the same racing stripe down the front of the cap.

Re: 1964 Larson 16' All American Project

Get a 4 1/2" grinder with a rubber backup plate. Get some 34 grit Stick on Sanding Discs and git after it. It will cut thru that old wood like hot butter. You should PLAN on removing the entire floor and replacing the stringer cuz they're gunna be as rotten as the transom. Count on it. BUT when you are done, She'll be BETTER than NEW and Last Long enuf that your Grandkids will be able to enjoy her. Let me know ANYTIME if you need ANY help. I LOVE this style of Old runabout.

Re: 1964 Larson 16' All American Project

Got a full day of work in today, man it felt good to get so much done.

I started off by heading to harbor freight for some cutting tools. I went with a 4" rubber grinder plate with 4.5" cutting disk. I really liked the idea of having the rubber plate preventing me from cutting too deep and it worked great.

The transom came out without too much work. You can see the top pieces are still on, they were made of different pieces of wood so I left them for now. I can always take them off if I decide to go with one solid transom.

I had some big cardboard boxes and traced a template of the floor before I started cutting. I was pretty nervous about cutting with the grinder that close to the hull but once I got in there it was pretty smooth sailing. This is the first section I took out of the floor just so I could get an idea of what was underneath. You can see the standing water, its really made think about how to improve drainage this time around. The only visible damage to any of the stringers can be seen on the right where the wood is exposed.

The floor is out! The fiberglass around the stringers is really solid, I was walking around on it all day and there was no flex anywhere. I was thinking about cutting the fiberglass off of the top cleaning all of the wood out and pouring seacast in then recapping with fiberglass would be a faster/stringer alternative to cutting out and replacing all the old glass and wood. Any thoughts?

Re: 1964 Larson 16' All American Project

I have a 1965 Larson Valero that I rebuilt floor and transom on. I think your going to find that those stringers are hollow fiberglass with just a wood strip glassed in on the top. This is Larson's double hull design. Shouldn't need to do any cutting on those stringers. Just clean them up on top and glue the new floor to them. I cut mine so that I could build a better and larger bilge than the original small fiberglass tub. You can see it in the second picture. You can see in the picture a hole I left in the bottom of the bilge through to the hull for the FF transducer to shoot through and for the bilge pump to fully drain the bilge. Works great, but haven't gotten around to fastening either one down in the hole yet.

Re: 1964 Larson 16' All American Project

Brett,

If you tried to Post pics, they did not make it. Check out my signature for a link on how to post em.
Your transom MUST BE ONE PIECE! Hopefully you measured it before hand to know how thick it was. Should have been 1 1/2 to 2 " thick. You should laminate pieces of CDX ext. Grade plywood using Fiberglass Mat and resin and then use thickened resin and mat to adhere it to the outer skin of the transom. There are PLENTY of examples on how to do it here on the forum. Remove ALL of the wood from the transom. As for the stringers, Take a 3/8 inch drill bit and drill into them down low and see if you get dry light tan shavings. If you do then you're good to go. If you get powder or dark brown wet shavings then you will need to cut em out and replace them. If they are good you can fill the holes with 3M 5200 sealant.

Re: 1964 Larson 16' All American Project

The pictures seem to be working fine for me.

I think Jeff is right. There is just a little plywood at the top of the stringers and they are really solid so I'm going to clean them up and glue the new deck down on the existing stringers. I like the idea of a new bilge though, the existing one seems less than adequate.
