did you have to do any reinforcing mods to it or was it pretty much ready to go when you got it? what engine and engine mods does it have?

Wax,

My recommendation is to get the graduated plastic cups versus the pumps. I have used the pumps before and I obtain much better results using the cups (measured by volume). The pumps tend to suck air and the mix ratios tend to get fluky. Also if you plan to mix large batches of epoxy, the pumps will take forever compared to just pouring and mixing. Just my two cents.

I stopped using the pumps... I like the graduated cups better too. :biggthumpup:

the only time i have had any air in the pumps is if they have sat awhile. push it until all the air is out, stop and let the handle come back up to fill completely with resin. good to go.

Yeah, I tried all that. I never got good results. My pumps could have been faulty for all I know or the viscosity could have been off because it was too cold which would explain why it didn't pump correctly. At the time, I was doing a stringer repair on my 21 ft. boat which required fiberglass in big sizes. Read 4' X 4' sheets.:smile: I would have been there all day pumping with the amount of epoxy I needed to glass that in. :biggthumpup:

Nope not hard at all bro, buy it in right containers and buy the $6 pump set and its one squirt per bottle, much easier than polyester mixxing. Check out uscomposits.com they sell perfect kits. http://www.uscomposites.com/epoxy.html
Im not sure what pumps you have but my pump kit from U.S. Composites actually meter the same so on the medium hardener its three pumps resin one pump hardener on the fast its 4 pumps resin 1 pump hardener. Just wanting to clarify so no one mixes wrong but like I said not sure we are using the same kit. Also I saw someone mention west marine is expensive on everything. West systems is not owned by west marine. You can buy west systems at almost any epoxy supplier. I have used west and U.S composites and find no difference but price. Also if you will take a measuring cup and mark the pumps in increments it will save you a ton of resin. That way you can mix half batches and stuff. I cant tell you how much resin I have thrown away because I mixed too much:frown:

Basically mixing 4 pumps resin to 1 pump hardener (4:1) or whatever ratio your specific epoxy calls for is mixing by volume. Using the graduated cups allows you to mix any size batch you want without the need waste.
