along the same question that Bradford asked. Did all 15 gal go to the V, or did you do your little boat also?

great job, great post......Hammer would be proud

I really like the detail in this post,
I think I could do a transom this way aaaaannnnndd
I think I may need to do mine in the next couple of years.

:clap::clap:

I just took measurements with a tape measure and drew it out on engineering paper. The key is the thickness. I did my calcs using 1 3/4 inch wood thickness and the dimensions were out to the sides of the hull. I came up with almost 4000 cubic inches or almost 17 gallons. I took about a gallon off of that for outter hull thickness. I knew it would be close. The void was closer to 1 1/2 inches thick and the void didn't extend up as far on the sides as I thought. I ended up using about 14 gallons total. I had received a free gallon of the stuff as a sample a while back so I had about 16 gallons on hand. When I did the sides, I mixed up a gallon at a time.

Spareparts, I don't own a little boat - that was tsubaki's contribution to the post.

Its not 100% complete, but here are some of my thoughts. I DID NOT want to pull the cap or cut it in any way. I don't go offshore much anymore - this boat will spend most of its life in the lakes and bayous down here pulling tubes and keeping beer cold. I feel this transom will certainly hold up to that. I live in a subdivision so I can't (nor did I want to) have boat parts spread all over my yard for weeks on end. I wasn't able to hang a hoist from anything to pull the cap off so I chose this method. I was able to contain the mess to my boat port. Finally, the cost was probably a little more than wood and glass, but not much. Quality resin is expensive. And obviously, taking it to someone would have been $2k easy. My transom in my old 75' V was $1500 about 15 years ago. I didn't have that $$ to invest in a boat I paid about $4k for.

Removing the wood is by far the hardest part (except for removing a 175 Johnson without a hoist!) So far, I have about 10-12 solid hours in the project (removing the wood was most of that time). The pour took longer than I thought - about 3 hours. That's mostly because of the upper parts of the transom and I had to let the lower part solidify so the stuff wouldn't ooze out when I poured. All in all, that's not bad.

Final pics and comments soon.

See if you took my word way back when, we could have all called for a sample like you then shipped to you and it would have been free!!

Remeber this parishht, you and 15 brothers and you all set!!:beer:

GREAT JOB Maury
 

:clap::beer:

Awesome work Maury! This is the best post ever for this method.

Do you know how much one gallon weighs? Trying to figure how much weight 14 - 15 gallons is going to add to the rear end....of course after you subtract weight for the wood and resin you would have used I'm sure its not all that much heavier. That should last forever!

Great job! You deserve a cold miller lite after all of that!

Per the Arjay website,

Weight per gallon: 7.1 - 7.3 lbs/gal

Heck thats only 110 pounds give or take!! Thats nothing!!

thats great work keep the pics coming
