I am a brand new member and happy to find this site.
I have been boating for many years and my main boat is a Pursuit 2460 Denali which I have owned for 10 years. I recently acquired a 1962 Lone Star Vacationer from the widow of a friend who passed away last year. The boat has been sitting outside untouched for 40 years and it shows. Much of the deck is rotted away and the transom is rotted. It has a 1961 Evinrude Lark III 40 hp that "broke down" 40 years ago and was the reason it was parked. I replaced the trailer wheels and tires, bearings and one hub, put on new lights and towed it home to the Albany NY area from Eastern Long Island NY. Once home, I cleaned out the mess that was just as he left it 40 years ago including the wooden water skiis in the cabin. I also started to poke around the engine and found it had compression of 95 psi and clean oil in the lower unit. I cleaned it up and replaced, coils, condensers, points, plugs, and wires, rebuilt the carb and fuel pump, replaced the thermostat and impeller and changed the lower unit oil. It started right up and ran good. Then I repaired the damaged cowl and painted the engine. Now its time to attack the transom and the rotted floors and bulkheads. No rush but it will be a fun project. I will try to attach some pics and I look forward to picking your collective brains on advice.
Welcome aboard HNT and beautiful find. She's going to be awesome when your done. There are plenty of folks here who can help as you go through your restoration. Post your questions and we'll answer them.
Is 40 hp enough for this boat? It is rated for 90 hp but it came with the 40 hp. It had water skis in it and the previous owner's widow said he used to take the kids skiing but it seem it will be really under powered. I don't need or expect a speed demon but I would like it to be able to plane with a few folks in it, The boat came with two props. No tach on the boat but I have an optical tach that I can use to check the WOT revs. The engine is all ready so I think I will just try it and see.
I removed the transom today. I cant' believe it but the transom plywood is laminated to 1.75". That seems very heavy for a boat this size. I would have expected 1.5"..The outer transom skin is .2" which I will bond the new transom to. The inside only had one layer of glass and tabbing of one or two layers onto the floor and hull sides. The glass on the transom itself only went about 3/4 to the top and the splashwell had a .1" glass skin that went to the top of the transom. the only holding the splash well to the inner transom skin was a bit of adhesive.
I am doing this project on a budget because I have another boat that always seems to find my wallet and drains it. I know that marine grade plywood and epoxy is the gold standard but I will be using BC ULX Exterior Plywood from Lowes and Polyester resin to save $. (The original transom was not marine grade plywood either). My plan is to use 2 3/4" sheets coated in resin to seal. I will then bond them together with resin and a layer of 1.5 oz CSM. Then I will bond the transom to the outer skin with resin and a layer of 1.5 oz CSM and clamp and screw to dry. Then I will put filets and two tab layers of 1708 to the floor and hull sides on the inside followed by 2 or 3 layers of 1708 over the entire transom inner face extending onto the floor and hull sides. Then bond the splashwell to the transom and glass in place. Does that sound like a good plan? It is not quite as thick total plywood but much more glass on the transom compared to original.
Really great find! Dr. Go is probably drooling over those skis. The 40 would be "adequate" but unless the kids weighed under 50# I wouldn't think skiing was an option. I would think a 75hp would be a good fit for cruising and skiing. Neat that it even has a pooper in it.
Your transom plans look spot on. There are plenty of threads here that can get you over any humps.
Glad to see another restore.
Yep I agree with Cal, 40 won't be enough to really do what you do with your other boat. 75hp or slightly large would be good. As far as the plywood plan, agree it sounds good the only thing I would caution is when marine ply is recommended it is because there should be zero voids in any of the layers within the ply. Now I can't say for sure if the BC ULX exterior doesn't have any voids but I would expect it probably has some. You just don't want voids in ply that's going to be that important of a structure as you transom. The rest of the plan is very solid.
I know a 3 cylinder OMC 70 hp or a 3 cylinder 90 hp Yamaha would be a good fit but they just don't have the right look for the boat. Plus I have my Lark III all fixed up so "plan A" will be to try it and see if it gets on plane okay and can move along. If that does' t work then its off to Plan "B".
The hull weights 960 lbs dry and has a pretty flat bottom, LOA is 16'9".
I would be interested in hearing from anyone with a similar hull powered by a 40 hp.
I don't want to ski. Just cruise and maybe a bit of fishing with a buddy. Most of the time I will be solo with my dog.
I am proceeding with the transom rebuild. I bought the plywood so I will get that cut and fit while I wait to get the fiberglass supplies.......whenever that will be.
Great project and love the style. Too bad the boat isn’t a bit longer as it seems some late 50s and early 60s cruisers sometimes had twin 35 or twin 40 outboards or that could be your plan C to find a matching lark. Also gets you back to the dock if one stops running. Never take my ideas too seriously, as I don’t always come up with wise ideas... just always loved the look of twins. Good luck with pursuing your own ideas!
Twins!!! That would be awesome!!! It would be less weight than a single, modern 4 stroke.... and a whole lot cheaper. Hmmmm
I'm starting to think I should find a larger motor and set the boat up for it as I build it out. Especially if the 40 hp is going to be a disappointment performance wise. I found a late 70's ? Mercury 800, 4 cylinder, 80 hp that supposedly runs good close by for a reasonable price. I might pick that up if it has good compression. Not exactly a tower of power but kind of retro styling that would fit the boat.
Any idea what a tuned up and freshened up Lark III is worth?
