I used Duplicolor rattle can. The stuff does not get efected by the resin, being I resin over the paint.

Why did you paint the stringers?
Title: Re: Boat repair
Post by: Ema Non-Performance Marine - BANNED on February 06, 2007, 09:28:31 PM
I had to do a lot of repair on the stringers, and I also wanted them to look different, contrast than the rest of the hull. They also looked like crap.

How hard would it be to put full length strigers in a boat . A friend of mine did it . I was just thinkin I'll leave it to a profesional.

Most boats don't get their strength from the stringers. The full stingers are actually better for mounting things to. As far as true strength, it is a combonation of everything. The boat that you see about is very week. It has tons of cracks in the gell and the thick glass shows threw the gell. As far as what I have done to this boat it has made it stronger but I bet that Saguaro is 10 times the boat as this POS.
I am going to add some kickers to mine in line and tied into the stringers (Engine Box) for mounting my seats.

what? no splatter paint?!?

I just dont understand why most boat manufacturer do that 80's splatter paint in the engine bay.........i was at the boat show and couldnt believe that every new boat had it....didnt matter if it was a $40k or $140k boat....they all had that same tacky engine bay that looked like the 80's threw up in it.

whats next? the return of the 90's day glow?
Title: Re: Boat repair
Post by: hotrod56cars on February 06, 2007, 11:32:24 PM
Not that I know WTF I am talking about...

The length of the stringers has to have some effect of the strength of the hull. Every single manufacturer can't be lieing. I know my two Rogers hulls have different max. HP ratings and the only difference is one foot hull length and full length stringers vs. 3/4 length stringers. The stringer length has to change the "cattey-corner" (technical term  :D ) strength/flex of the hull.
Title: Re: Boat repair
Post by: Ema Non-Performance Marine - BANNED on February 06, 2007, 11:42:12 PM
Actually this boat had the worst I have seen, tortional flex. Once I repaird the bullshit bulkhead panel and turned it into a rib it fixed the tortional twisties. You could pick up the right rear 4" and it would flex 5"at the bulkhead. I have no idea what I am talking about, being I used to build real boat out of wood like the Ark that Noah had. By the way stringers tie the ribs together and plastc (glass) boats in general don't have them. Except for the top boat builders of the time.

Here are some pics of the intake install and spoon or bubble;

I used to use the Duplicolor white engine paint, really good stuff but you have a real long layover between coats (looks & Durable like powder coat). I have been using the Pure/Linen White Duplicolor rattle can paint. I can't wait to get a permit for spraying  paint. I use it on all the pumps I do.

ok i will bring the pic here. as you can see i have two post type motor mounts that mount to the side of the motor and that is it. they bell housing mates up the the jet drive to hold the back in place. this seemed not right to me when i was putting it back together. but this is my first boat and i did not know about this page. i wish i would have i probably would have done some things differently. any ideas would be great to hear.

Glenwood Marine is still in business, new mounts. http://www.glenwoodmarine.com/

eBay for used mounts.

Guardian Marine and Glenwood Marine mounts are the same. Nicson Marine engine mounts are very similar but a little different. There's several others out there (now defunct, I think). There's a set of mounts that you commented earlier on in a different thread that you liked, they looked like Glenwood type mounts. The mounts on my Cheby are Guardian.

that is what i am looking for. i like the cast aluminum mounts with the rubber mounts. the bad thing is that i would have to cut apart my new floor to get them installed. i think i am going to change the ujoint first and if that does not cut it this is the way i will go.
Title: Re: Boat repair
Post by: hotrod56cars on April 12, 2007, 08:32:39 PM
I tried to find the pic I saw of your stringer's/floor, I couldn't find it. You shouldn't have to cut anything, the front mount is about 1 1/4" thick, it's flat, and "sticks out" less than the pulley/altenator.

I looked at a Tahiti one time to buy and it had a Panther pump also. It's engine mounts looked homemade as well. Now I'm wondering if Panther engine mounts are supposed to look that way...   ???

He will have to cut the floor away if he switches to the glenwood style mounts. There's a floor that that runs from the lifting strake and butts to the stringer. That will have to be removed, or an acess hole cut into it, to have access to the bolts holding the feet in. Normally this area has the floor on top of the stiringer, or none at all. Never to the center of the stringer. Kinda strange.  :)

looks to me that floor was put in after the fact without much planning involved. the outside of the strings arent even accessable thus rendering them useless to mount (bolt) anything to them.

Nice photos and it'll help me when I do the repairs while my engine is getting rebuilt.  My bolts going through the stringers are carriage bolt that have been sucked up so far that they are almost buried in the wood.  Those will get pulled, plugged and glassed over.  Then I'll put aluminum backing plates so this won't happen again.

Do you have any good suggestions as to how to make sure I get any oil removed from the wood without replacing the stringers before I glass them in?   Nice work!  Greg

They make stringer washers to keep the bolts from getting "sucked in" I think you can even get powder coated ones to add to bling factor O0

Too bad the previous owner didn't use some sort of washer but not one on the stringers.  So now I get to deal with making it right.  What else is new.  :)

In my opinion the best way to fix your problem would be to get some flat 1/4" thick by 4" wide and span it the length of the motor + maybe 4" past each side . Drill it and then use the stringer washers . Similar to a rail kit . It disributes the weight of the motor across a larger span on the stringer . Alot of times people fix shit with a band aid and here we are fixing a band aid . This all only assuming your stringers aren't rotten on the inside .

Great thread too Jim . Very informative and a great lesson . ;)

Well, I can go get some 1/4" x 4" x 8' aluminum plate and that will give the 3' needed to span the motor mounts plus 4" in each end.  I'll post some motor mount photos in a few minutes.

Motor mount stringer condition:

Rear mount shows a little wood damage but I think to get through the rest of this summer, the 1/4" plate, as suggested above should give enough support for the few more runs I might make.

(https://www.socaljetboats.com/proxy.php?request=http%3A%2F%2Fgregaw.home.comcast.net%2Fmotor_mounts_002ss.jpg&hash=d4a2848f30c56944c21116bcf58216c6cf906eb0)
Front mount stringer condition looks good.

I wonder if that dry rot repair stuff would help out.
Title: Re: Boat repair
Post by: Ema Non-Performance Marine - BANNED on September 07, 2007, 06:31:11 PM
I bet that is a factory install on the carriage bolts. I have seen that quite a few times.

The best way to handle this is to, drill out the rotted wood and install a hard wood dowel. It is important to make sure you do not have any black or soft wood remaining after drilling. You will then grind out a divet that is aproximatly 1/2" - 3/4" larger than the dowel hole. This way you can lay two layers of fiber glass cloth to help secure the repair. Now to install the dowels you will want to make up some resin and completely saturate the dowel and install, you should have to tap the dowel in with a hammer. Now the new engine mount bolts need to have a long shoulder that extendes the width of the stringer and the foot of the mount with the stringer washer in place. This way the slight movement of the engine does not cause a sawing action from the threads, causing oval holes. Bergeron Marine has some very nice stringer washers, that come in many different diameters and colors. I use the real large diameter washers on the thin stringer boats or on the high HP applications. After you do the repair it should last two of your life times as the one that we are discusing has lasted probably 25 years already. Remember this is not a race boat, it is a lake/river hot rod.

Here are a few pics of the dowels installed and one of the bilge prior to work.

Thanks Jim,  That looks easy enough.   ::)  Easy for me to say, huh???  :)  Since It's been a long time since I did any glass work.  First thing is to get the motor out and to the shop and then clean the crud out of the bilge!  Simple Green, Tide and Dawn dish soap should do the trick.
