Munro 16ft Tri-hull project

I'm new to the boating world and figured this was a good place to get advice and info on my MIDLIFE crisis(as my wife puts it)
I recently purchased an old boat year? I know its a Munro 16ft bowrider built in london,ON. but other than that its a guessin' game still have to go and try and get the ownership that should be fun.
When I bought it,it had interior but no motor he kept that for his new boat. When I picked it up he had decided the interior needed to go turns out the floor had water rot so he replaced half of it and now I get to build from there I guess.
Although by the looks of it ill have to take it all apart and redo it.
Well here's lookin' forward to a summer of my new hobby.

Nice looking tri hull.
Im guessing it a 70's ish that had a Johnson OB short shaft, in the 50-85 HP range.
From the pics the floor seems to in good shape, is it only one layer? Is the foam new and or dry? Looks like a good project. Have fun.

Re: Hi All

Re: Hi All

the foam is original he just unwrapped it all for me lol.
from what I can see there is still rot under the new plywood especially at the back under where the battery sits looks like he just screwed new plywood over the old rotted floor ill know more once I get my hands dirty.
but overall the the fiberglass is in good shape for the age no cracks or spidering or wear spots and for 500 bucks Im not complaining

Re: Hi All

Yea, a double layer floor is only worth,,,,,well nothing.
Tear it out and rip out the foam, start from scratch. Its fun and keeps you out of trouble...
There are tons of threads on resto's here. Including mine.
Once your into it, its like theropy.
Take your time and do it right, you will enjoy it for a long time.

Re: Hi All

nice looking boat. instead of attaching thumbnails post the pic in the body of the post, by copy the link and attaching using the photo iconjust to the left of the quotes and right of the email link. it will be easier for people to see and will get more responses... just a suggestion
good luck

Re: Hi All

How many layers of flooring should I put down. Once Ive replaced the foam, whats a decent brand of sealant for the flooring once its done? would a deck sealer work or should I go with a specific marine brand?

Re: Hi All

Re: Hi All

Put down 1/2"-3/4" plywood for your deck. I personally have used 3/4" in both my projects and like the solidness of it. Your choice of wood and your sealant methods will be determined by how long you want it to last and how much money you want to spend. Marine plywood is a superior product. It uses top quality glue and has far fewer voids. However it is expensive. Many of us are using regular exterior ply. Since you have a fiberglass hull you can use pressure treated if you want but it will need to be thoroughly dried out first. For sealing it, the best would be a layer or two of fiberglass and either polyester or epoxy resin. 2nd would be just a couple coats of epoxy resin (poly is no good by itself). 3rd would be marine spar varnish and last would be quality porch and floor paint. Sealers like Thompon's and what not are pretty well worthless.

Thanks ezmobee
I was thinking about 3/4" but the info on sealants is much appreciated.
Having A hell of a heat wave here now so Im gonna have to wait a few days to get at it.working outside(no garage)

Hi there, i pretty much have the same boat but with a 85hp johnson i'm presently working on. Are there any books ( with lots of pictures! ) on how to repair the floor in this thing? I have read what some of you have posted but i just can't picture it.

Thanks

There is a book you can get on Amazon called "Runabout Renovation". However, you won't find better tutorials than reading the various project threads right here.

Re: Munro 16ft Tri-hull project

Well, i just went oustide and pushed up on the engine and it has about .25 to .5 inches of play, is this normal? This is my first boat which was insanely cheap... should i keep it or put the motor on something else??
