inside the motor mount

What would be the logical next step? How big of a job does this look like? ANY idea what repairing this might cost at a shop?

Re: opinion on hull repair needed *pics inside*

If she were mine, I'd drill into the motor mounts with a 1/4" drill bit. Put some tape on the bit about 1 1/2" up so you only go that deep. Check the shavings from the drill. If they are totally dry and a light color then OK. If damp or wet and dark color then NOT OK!! Do the same thing on the transom FROM THE INSIDE. If the shavings are dry and OK then you can use some 3M 5200 sealant to fill the holes. Your Hull problems are located on the KEEL and if this is the ONLY problem you have then it can be fixed from the outside and you can continue to use the boat. If you have wet stringers and transom then you have a lot of restoration work ahead of you.

Re: opinion on hull repair needed *pics inside*

Ok, so just to clarify, drill next the motor mount like next to where the mount bolts to? Again I am knew to boating, and I apologize for the ignorance, but the mount is sort of like a box that is open on the rear. Those pictures are reaching inside the "box" with a camera. For the transom, I am assuming the lower the better same deal with 1 1/2"? It is really tight in the engine bay.
Thanks again.

Re: opinion on hull repair needed *pics inside*

I believe this is your motor mount so drill here.

and yes drill down low and in a couple of places.

Re: opinion on hull repair needed *pics inside*

UPDATE
Ok so, with major knots in my stomach, I took a drill to the boat just now. I salvaged what I could of the shavings. Some are a little darker than others everything is definitely totally dry. The engine compartment is very dirty, black oil/crap all over. The bottom is almost completly dry. I have a hair dryer on it now. Here is a picture, any input is appreciated.
Thanks.

Re: opinion on hull repair needed *pics inside*

difficult to say if the black is wood or glass ....feel it......if the black is wood.......not good.

but you say its dry?

you have kept asking if you can dry the boat out........

no ....you cant.....it will never dry out. that is why removal of the wet is the only way.

you can repair the hole from the bottom. (there is a special way to do that repair) but keep in mind.....if you do that...... you will seal in the wet wood......rot will continue.....and the hull toast with in three years.

the other thing is, if you try to sell the boat after two years.......you would be selling it as a project boat....not as a good working boat.
regardless of how pretty the inside looks and how well the motor runs

Re: opinion on hull repair needed *pics inside*

Sorry for the crappy cell phone picture the black must be fiberglass or some other crud. Some of the shavings I got are darker than others but none black or wet at all. I dabbed the damaged area underneath firmly with paper towels and there was only very slight moisture in the exposed fiberglass area none really on the exposed wood Not even enough to bleed through to the second layer of paper towel.

This is my first boat and before this have 0 boating expierience. I have not even been able to have the boat in the water before. I am of the mind to do the proper fix that is reliable. The boat is going to stay in the water during the season on a neighborhood pier. I dont really have plans to sell it anytime soon. Does this look like it would this be safe to operate? If I do the repair from the bottom, what would be the proper procedure?

Re: opinion on hull repair needed *pics inside*

Well by looking at the pictures it looks like the hole has been there some time and has been leaking and wetting the wood.
It looks to me like it is right on the edge of a bulkead, Is that the edge of a piece of plywood?
Have you done any measurements from the stern to see actually where the hole is in reference to what is in it's way on the inside?

That would help to give people ideas on what to tell you.

Re: opinion on hull repair needed *pics inside*

The damaged are is quite litereally directly below the engine. The Bilge pump is mounted just in front of it. I cannot see it from the inside.

Re: opinion on hull repair needed *pics inside*

If the shavings came from the area I circled for you to drill and they are dry then thats good. Fill the holes with 3M 5200. IMHO for that damage on the bottom I'd say wipe it down with acetone, fill it with structural Peanut Butter (poly resin, cabosil, and strands of CSM so it's kinda "Hairy" and the consistency of Peanut Butter) Use a Putty knife to fill the hole and smooth it out. It will set up and cure n 45 minutes. Sand and smooth and then mix up some Gelcoat past and brush on several coats. Use 220 grit to sand and got have fun.

Re: opinion on hull repair needed *pics inside*

Yes. I drilled two holes on the right mount and three in the left, two in the front, one in back. Right where you circled. It was a real bear to try and fit the drill in there. And two holes on the transom as well.

Re: opinion on hull repair needed *pics inside*

Do what WOD said for the repair....as the plywood you would be seeing is just the piece of plywood you see there for mounting the bilge pump. leave something there for a few days like a heat lamp...then do the repair..The only place that will get wet from this hole is under the piece of plywood .....If the repair does not hold up for you after a season...the proper way to repair it in the off season some day is to grind out around the piece of plywood laminated to the the hull that the pump is mounted on...let the hull dry out in that area ...repair the hole on the inside and outside and replace the piece of plywood then fiberglass back in.

but that requires pulling the motor

Do what WOD said and have some fun and check the repair out when the season is over if you are still happy carry on

Re: opinion on hull repair needed *pics inside*

I think I understand your problem mike ..

First thing is first.. You need to grind/dish out your repair more anyways..so bevel it out now ( about 6" round ). Then get a fan on it ( you dont want a hair dryer or a heat gun on it ). Your trying to evaporate the water..not steam it .

The wood that you see from the outside in your repair is actually a keel strip. Basically..they lam up the hull..then put down a strip of ply in the keel and glass over that. See how the bilge pump is screwed down to the hull..well its actually into that mount strip and not the hull itself. I would recommend you reseal the Bilge pump at this point.

So.. grind away a bit more on the repair..let it surface dry out for a few days and see if more water is coming to the surface of the repair. We can go from there . Send more pics after this is done.

You will be using VE resin btw ..

Its not a big repair or a tear.. and your mount board is not structural and seems to be encapsulated .. so Im not really worried right now .

YD.

Re: opinion on hull repair needed *pics inside*

That sounds encouraging. I will do that and update with pictures.

Thank you guys.

Re: opinion on hull repair needed *pics inside*

I ground it out today. I'll check tomorrow for any moisture. It was dry when I came to it today though.

 

[Outback Jack]

Re: opinion on hull repair needed *pics inside*

Nice prep work and exactly what I would have done to see if it was dry, looks good to me . That is why I asked where it was at first , because the repair can be as this simple. Now I know what I would do to repair it. A good mixture of pb followed by a layer of csm then 1708 then a couple layers of csm. Then the fairing material . But like always I will let the people that do it everyday and gave me guidance chime in and give some advice...jump in there guys

Cheers

Re: opinion on hull repair needed *pics inside*

Looking good on the grinding ( might want to feather a little bit more on that other side ) .

Let it dry up if its not already dry and back pack with the filler and glass if its not still leaking H2O ..

YD.

Re: opinion on hull repair needed *pics inside*

I am trying to put together a shopping list here to get the supplies for the repair. Yacht dr., What is VE resin?
Are there any videos/writeups on this sort of repair? Would a marine store be the best place to get fiberglass materials? ie West marine?
Thanks again guys.
