hello all this is my first post.

i have a 1965 sea king cuddy cabin 18 foot fiberglass, it was designed and built by starcraft. in 1965 this boat was decked out with all the features but over the years no one took care of the boat and simple fixes turn to major ones.

so this is what i am doing, we (my girlfriend and I) have striped the boat of all the hardware, removed the center wall that closes in the cabin, and i have pretty much tore out all of the transom. about 1/4 of the transom was rotted, yes i could have used some products to do a much faster repair but when doing something way not make it how you want it.

the old sea king 80hp outboard is off and waiting to be taken apart to be sold for parts to recoup some of our money, tip to all dont just trash everything cause someone else may need parts. the new motor is a 85hp evinrude.

the budget.
the budget is no more then 3000 bucks for everything, the boat was 450 and the new motor was 400 and the legal side was 175. we have already spent 800 on supplies.

the plan.
i will be adding a full transom swim platform and outboard motor bracket with the new transom being a full one instead of having a cut out for an outboard. it will move the motor back 20 inchs. it will be 14 inchs high 20 inchs deep and 70 inchs wide. it will be made for plywood,(15/32,4ply sheathing grade and 1/4 hardwood plywood) and fiberglass. the fiberglass is 2 oz cloth 72 inchs wide .004 thick. the resain is ployester not epoxy due to the cost.
the thinest section will be 2 layers.
the new transom will have 2 hollow sections to the right and left of the center section,the hollow sections will be to reduce weight. 1 soild 15/32,then 2 layers of 6 inch wide 15/32 strips, and then 1 soild piece of 1/4 hardwood plywood. the 1/4 inch side will face the inside of the boat. all will be screwed and glued together and then sealed.
the swim platform and motor bracket will be one piece and will be fixed to the transom with screws, bolts and glue.
once the swim platform/bracket and transom are built they will be fibegrassed. then the whole piece will mounted to the boat.
this mounting will be done with adhesive with screw to hold while the adhesive sets, then it will be fibergassed over from the deck up and over the transom to the swim platform with 3 layers. 4 half inch bolts then will ran through the the transom.
the roof of the cabin will also get some added fiberglass support as my girlfriend and sister both wish to sit on top of it and 47 year old fiberglass may not hold up to the two of them on it as it wasnt designed for this to start.

repairs need else where.
on the inside of the boat cracks are starting on the sides near the floor, they are not bad boat sea king boats had this problem and it can get really bad. my father and his bother in high school had a sea king runabout and on one trip a small crack split wide open and the boat was almost lost. so as you all can figure i do not wish to have that trip in my boat i will be fixing these now. the repair will be done by craving out the crack section a little, then 9 oz 2 inch wide cloth will be pressed in using small pieces with the 2 oz cloth going over top of it all with a 3 inch overlap of each side of the crack section and then a 6 inch wide stip of the 2 oz cloth with run down the whole side tying into the new fiberglass of the transom.

well that is a fast rundown of the project. i will update and post pictures along the way. its the start of may and i want the project sea ready come the middle of june.Slide1.JPGSlide6.JPG0316021438.jpg0404021437.jpg0404021439.jpgSlide1.JPGSlide6.JPG0316021438.jpg0404021437.jpg0404021439.jpg

Re: 1965 sea king restore and upgrades

hello all
well it was a productive day on the old sea king.
the old transom wood is all out and the section is cleaned up. a templet was made and test fitted. it is always good to keep scrap wood around, the wood used for the templet was left over from the subwoofer boxes i made for mine and jens trucks.
the benches in the cabin will need to be replaced due to rot, but they are somewhat fiberglassed in so out comes the grinder again. a cordless grinder is a great tool and if you done have one go get one.
today jen finished sanding the old door, it was weathered pretty bad over the years. she did a great job at removing the rotten sections, they were just starting so a little putty will take care of it. then stain and varishing.

if anyone has any ideas, questions, or just something to say about the project please post.

today my brother asked me why i would spend so much time and money on a 1965 boat.
well find a 18 foot cabin crusier today with this much room and what will it cost to buy it. also these old boats just have beautiful lines where someone designed this boat by hand not with a computer.
tomorrow were to get rain so dont see much work getting done, but tuesday the weather is to be good.0505021523.jpg0505021524.jpg0505021524a.jpgView attachment 145161

Re: 1965 sea king restore and upgrades

ok....from re reading twice so i think i under stand you.....

you want to build a bracket from the transom.....that kinda looks like the pie symbol
(two boards straight out from the transom with a piece for the motor to hang off between them......right?

well....im sorry to say......you cutting the transom off is the worst thing you could have done.
and the fiberglass cloth you are planning to use is no where hear what you need to do this.

the 2 oz is a finishing veil.....and has very little structural stregnth....(almost none for this application)

when you cut the transom off, you lost all reference points to the bow.

if you mis calculate.....even a 1/4 inch.....the boat will push sideways thrught the water....kinda like a car dog tracks when the frame is bent.

the alignment to the planing surface must be true....as well the angle of attack must be at 110 deg...(20 off vertical) or the boat will submarine or porpose.

the info to do this job is on these pages here at iboats.....
it is always a good idea to investigate the idea before you start cutting.

it can be fixed.....but the amount of work just tripled....
i thin you might have to push the splash date back unless you can spend multliple hours a day on this project.

im sorry if this is not what you wanted to hear....but my friend......you royaly messed up.

we can get you out of it....but you need to do some reading here.....
start with the sticky at the top of this forum.....it has fiberglassing info that includes discriptions of the different types of fiberglass cloth knit and csm......it will also speak to there proper uses in a certain application.

cheers my friend....we can help you fix this

it will be a pod/motor bracket but will be built as part of the new transom, 1 build the transom, then build the bracket and on the new transom and last install it all in the boat. so i guess it would be a hull extension as it will all be one piece when im done.

i just read your second post, and that is kinda what i wanted to hear, if you plan for the worse you can make it through the best.
when it comes to the placement of the new transome i took about 10 points to get the placement and i left about 1/2 over lap on the old outer fiberglass. i left the interfiberglass of the old transom in place, so there is kinda a slot for the new transome to slide into.
for the numbers i measured off the bow in a "V" shape and marked 3 spots 1 inch apart from eachother on both sides of the boat so that i could then measure from them in a "X" shape, like squaring a door(corner to corner).
this is the biggest boat project i have done, so all the help i can get is welcomed. i went into this in the same way as i do with frames of trucks and the placement of there equipement.
the oem transom angle was 104 degs from level using a dial. the old wood was 1 1/2 inch thick as is the new wood will be.
as the boat stands now i kept it where i could recore the transom and place the old fiberglass piece back on with new fiberglass over the old.
with the fiberglass im not sure on it so i design the wood to support almost all of the load and the fiberglass to protect the wood and tie it into the old. under the swim platform section there will be 3 sections a right, middle and a left with 2 pieces of 15/32 plywood dividing the sections

" \_|__|_/ " kinda like this.

i will attach pictures of what i got started with for this idea.
any advice pointers or whatever please post them. i posted for help and maybe to help others lol.DSCN3618.jpgDSCN3619.jpgDSCN3663 (350x262).jpgDSCN3753.jpgDSCN3860.jpg

like that but bigger and the bottom section is wider.

will the marks i used off the bow work, i was think maybe also making a full center line also and use all of the. like say a line 6 feet from the transom make a cross and measure in a V back to the the transon. have the transom marked 2 feet from center and square it from there and the side marks.

Re: 1965 sea king restore and upgrades

so the old transom is out and the new one is in. i started fiberglass the swim plat/ motor mount. the new transom is squared with all my marks and from the bow line its off by .023 of an inch, gotta love lasers( worth buying if you do a llot of work where things need to be lined up. to day i hope to get the swim plat/ motor mount attached. the inside is at a stand still as im only 1 person and my jennifer has been busy.
i will be using 5/8 ss bolts to attach the swim plat/motor mount and to attach the motor to the mount i will be using the same. epoxy will be used also once i know the swim plat/ motor mount is lined up.
the outer layer of fiberglass on the swim plat is now 1/8 of inch thick over 15/32 plywood with the center section 1/4 inch thick.
well off to work on the boat.

Re: 1965 sea king restore and upgrades

so the i got the boat out on the water and spent a good part of the summer out there. did make one big mistake on the swim plat/motor bracket the bottom angle is backwards from what i need. no joke poor thinking on my part so this winter and spring will do it again. it runs and all just not how i want it too. plus it was a lot of fun doing the build.
