Transom Repair With Seacast.

[JonM81]

Any Do's and Don'ts with this meathod. I am planning on diggin out the rot between the fiberglass and poar it right in. Any pros and cons to this idea? Also, how much would I need to do this porject for a 17' bass boat. Its about a 4x3 area roughly. Thanks guys... I'm going to start taking the motor off this evening!

Also, as I do this, the inside of the transom is somewhat weak. Will seacast strengthen the inside fiberglass as well??? I got the motor completely disconnected from the transom except for the trottle lines, anyone know how to disconnect these. Its a 80HP mercury 4 cylinder. Other than that its ready to come off... I'm gonna order 5gal bucket of seacast tomarrow... Thanks Again!

The web site has a formula to tell you how much you need, just do the math

I believe they have downloadable instructions on the site describing how to do this, including calculating the volume of the repair. Figure this out before you order that 5 gallons (too little or way too much). They sell at least down to 1 gallon quantities and it only has around a 6 month shelf life IIRC. As I figure it, the glass skins give the Seacast strength (durability) and the Seacast gives the glass skins the stiffness of a solid core (anyone can correct me if I'm wrong on any of this).

There is downloadable instructions for it and it works great from what I hear- I just replaced my transon on my 1973 crestliner 17 muskie and I used 1 1/4 marine plywood and fiberglassed it in - I did the entire job in about 25 hours with a partner- that included replacing the stringers with 3/4 plywood ( and glass) the whole job in materials cost about $500. good luck to you

Re: Transom Repair With Seacast.

couple things-- order just alitte more than you need. besure and seal any openings especially in inner glass area. in stead of to redrilling for drains etc use pvc of appriate size coated with vaseline, make them long enough to pull out by hand. Seacast is pretty self sealing, but you need to support the areas or it will cause the poured area to expand slightly. If you can get hold of an old road cone and cut off the top 4 or 5 inchs this makes a great funnel. cover all areas you do not want marred as this can get to be messy. Best to use a chain saw (carefully) to remove old wood. One with at least a 20 inch blade. once all the wood is out spray inside area with a good solvent to remove oil from chain saw. Will be ready to start installing motor next morning.

Re: Transom Repair With Seacast.

Quick Question before I pour in Seacast. I am fixing the inner fiberglass parts that were torn which is HELL in a bass boat. I dug about all I can from the top of the transom without having to take apart the back or inner fiberglass walls... Can I pour the transom in even if there is a little wood left at the bottom of the transon (way below the motor mount level)?? I know it doesnt bond to wood, so if this will not work, is there a product that I can put in befor seacast that will bond to both wood and seacast? Thanks again for your time!!

HI jonM18-<br />Also from San antonio. Have you started your project? Going to replace floor and stringers on my boat this winter( What little winter we have) .My transom seems good at this time, but not sure what I will find once I get the floor out. Was thinking about seacast. Let me know how it turns out if you use it.<br /><br />Thanks rude85
