Lip around transom on Blazer boat

[Shallowman]

This is a 15 foot by Blazer boats inc. Mid 80's hull . Rated for up to a 50 hp and has a lip around back of transom . There was wood put under it by someone or factory . Is the lip factory and why would it be there ? Do i mount something back under it as i don't see how motor would be flush if i don't ?

Is this Metal or Glass?

Its glass , its not quite the same width all the way across . Middle is 7/16 ( about 10 inches ) then it slowly goes down to 3/8 on each side .

Looks like a hull/deck flange to me .. yes that would be factory and yes you should put wood back to mount your motor back up .

YD.

Re: Lip around transom on Blazer boat

Thank you , the wood looks to be riveted on . Would glassed wood or Alum. be the better choice to replace it with ? Boat belongs to a friend who has it in my gargage to fix that and wants to replace the deck cause of a couple soft spots . Gonna ask about the floor in a new post .

No need to start a new post. Better to keep them all together.

Re: Lip around transom on Blazer boat

No problem ,


In the picture below , the blue outlined area is fiberglass with foam behind it . There does not appear to be wood behind it . The wood on the deck was thinner then i would of fiqured at 3/8 thick ( with glass was right at 7/16 inch thick ) Iam not able to tell how far under the "foam" area in blue the wood goes . How far up ( from deck ) would i need to cut to allow room to take the new deck under it and be able to glass it in at the edges ?

Re: Lip around transom on Blazer boat

Just looked thru alot of post on deck removal . I see how to remove a cap from boats , but couldn't find a post with pictures to give me ideas on what to do on the side .
The deck does run under that section so i know it needs to be cut out and replaced so i can glass the new deck down . Just not sure if i cut just enough to work back there to glass the edge of deck or basically cut the whole vertical section out and do the deck then use glassed wood to put back and have it glassed to deck .

Re: Lip around transom on Blazer boat

I dont think your gonna uncap this boat .. its bonded.

You need to get the console and other things out of the way for you to have access to the repair.

Tough repair IMHO ..

YD.

Correct , i found a few posts on deck replacments that had sides , but they were boats with a cap , which threw a wrench in my mix lol


Console was bolted in , along with other stuff . I currently have most of the floor out ( need to cut out livewell out ) . I agree, its not gonna be as easy as i was hoping . So the few thoughts i had are :

1) Just going slightly under the "sides" i'll call it and glassing to the deck to the "side" This would work for a few years iam guessing .

2) On the side , from the floor up cut about 6 inches up and i may be able to glass the deck to the inside of hull .. Use peanut butter mix to feel the gap . Not sure the best way to reconnect the 6 inches i cut out unless i just tab a few areas and then blend them back and reglass it to the deck. Like reattching a live well or storage box .

3) almost same as #2 except cut about 1 1/2 inch down from the top of the "side" , drop in the new deck and use 3/8 or 1/2 wood connected to the lip i left ( use 5200, temporary use screws till its dried ) and run it down to the new floor , glassing in that whole side .

On the last two above , iam not sure what it would do to the boat till i get the new deck in if i cut that "side" out

The foam looks good ( dirty but dry ) except a 3 or 4 pieces that were at the bottom rear of hull . They were damp on the bottom edge . I'll need to fiqure out the sides still and decide to drill the rivets or whatever was holdinh the wood plate on the transom.

Re: Lip around transom on Blazer boat

I dunno man..

All I can think of is to cut out the exposed deck .. feel whats under the walls.. Possibly leave whatever wood is underside of the walls ?

YD.

Re: Lip around transom on Blazer boat

Wahoo .. After my dinner i'll post a picture of what i did to deck and the side . might be a pain to reglass to make it look correct . Was not as bad as i thought , i did some supports to keep things in check . I supported the underside of hull and up the side of hull just to be safe . Even thou the boat is under 15 ft and the deck will be cut alittle under 48 inch wide i think it would of been fine .

Re: Lip around transom on Blazer boat

Alright i decide to about 6 inches up and see what it looked like , fiqured i can cut up more if i need to . I was suprised that the glass on the deck to side of the hull was very thin , not much resin . I am still not sure what to do where the livewell was , but there was a leak there as this area was damp for sure ( i did lightly rinse the hull out after cutting these section out ) I got plenty of access now so i don't see a problem getting the deck butted close to the inside of the hull . ?? Just use peanut butter to feel any space and fully glass to the inside of hull or just tab every so many inches ??

I did a couple stringer core checks , overall good and about what i expected . The only spot checked that i didn't like was near the rear of the middle stringer approx 10 inch from the end there is a spot about 2 inchs long that i can see where the glass was thin and i didn't see the bedding the stringer sat in like the other areas . As i said its about 2 inch long and about 2 inches high before i got "dry" material again , I 'll have to decide what to do here .

My camera is acting up , so i'll add picture of some foam from inside and have someone tell me if its closed cell or not . Its dry ,not heavy , or brittle so iam debating using it again .

Heres a couple pics =

Re: Lip around transom on Blazer boat

Humm near front of the boat , the middle stringer is just slightly higher then the ones on the sides , not very much but just enough to make the deck wobble near the edges . Is it normal on some boats for this , like a slight roll off ? Should i use just use pl or something one the 2 stringers that are slightly lower ?

Re: Lip around transom on Blazer boat

They may have done that intentionally to get water to run towards the bilge? Just throwing out ideas as I am of NO help when it comes to this stuff, but I do enjoy watching you guys do it.

Re: Lip around transom on Blazer boat

Iam thinking that is the case here . Every thing is solid , hull supported so i know it not a sag or something . Also i rechecked and it "levels" back the same the exact length on each side stringer . I'll need to decide if iam going with 3/8 what was there or go 1/2 inch . 3/8 just seems very thin ..............hummmm

Re: Lip around transom on Blazer boat

Any final advice before i sanding the inside of hull ? Was gonna use a 60 grit flap disk in the areas where the new deck will meet hull . Heres the last few things i need to decide :

1) Use 3/8 ply or upgrade to 1/2
2) Use Pl on top of stringers / or lightly grind to make the middle stringer slightly lower = more level .
3) Use PL or use PB on gap where deck meets the side of hull


Heres my rough plan :

Grind down inside of hull
3/8 or 1/2 ply coated with resin on bottom
add pl to top of stringers
Lay deck in , and pre drill holes to screw deck down with deck screws
there was no PB or anything in the gap where the deck would meet the hull , so i may do PB here this time
Use CS about 8 inch wide on edge of deck to hull
Use 2 layer CS on deck then 1 layer of biaxle

Your plan for the deck seems good no matter which way you take it .. However ..

Do you have any better over all pics of the repair area ?

How are you planning on glassin back that side panel ?

You really only need to be 'close' to the hull with your deck..not dead on.

YD.
