Looks very nice I like what you are doing with your console.

Try not to use anymore 5200 unless you doing something under the waterline, thruhull etc, and even then some would still stay away, switch to a silcone sealant or 4200

also I could not tell from the pictures so you may of alreadt done this but if not next time you drill a hole in the gelcoat, like mounting holes for your tab actuators, use a counter sink before you sink the screw. The counter sink will alleviate the possibilty of spider cracking.

Also listen to Hermco do not add unecesary fittings with your hydraulic steering. expesially when they are in the elements. Same goes for any electrical connection.

To see what the elements do look at this picture from Warthogs setup:

see how the chrome plated brass fitting around his engine rigging tube is already greening?, try not to use chrome plated brass/bronze unless you like polishing, stick with stainless, not quite the shine but will never turn green.

Although the picture may be mis-leading as I would never expect this type of tarnish from Warthog. (just razzing you Bobby as I imagine it is already glistining)

I think you need to add more filler and less microballoons to the mixture. You may have to put several coats of sanding primer over it to get rid of the pin holes. System 3 quick fair is the only way to go in my opinion. Once you have tried it you wont want to use anything else. It dries fast and is as smooth as butter.

trayder, thanks for the compliment. it is my first attempt at fiberglass. when i drilled the holes in the gel coat there was masking tape on the gel coat. i think for my motor rigging im just going to use the rubber boot with the tie-wrap at the end and run everything thru there.
strick, do you mean more filler as in cabosil or milled fibers or silica from west system? i am going to look into getting some of the system 3 product. i am willing to try anything.

I've pretty much quite mixing my own a long time ago. Pinhole's are a PITA and yes when the primer goes on it will show all kind's of stuff.

System 3 Quik fair is what I use. You may still get a few pinhole's but nothing like you will with stirring your concoction's together.

Those TH marine hose cuff's are chrome plated plastic. I was actually going to try and wax/polish them today. the rest of them on the boat are just Black plastic.

There are 2 more Black one's for the rigging tube going to the crow's nest.

ok well since i have made the console more narrow, i had to modify the inside of the boat a little. it used to have a place molded into the floor for the wires to go thru into the console.

so i had to cut that out .

i will post more pics tomorrow and explanation of how im going to modify this portion of the floor or suggestions would be great.

It has been a while since i worked on my boat. i too lost motivation but get it back watching fishing shows on saturday morning. the old console had the cooler in the front with both my batteries located in the rear. i have made a battery compartment and cooler combo. the batteries will go on the left and cooler on the right.

ok i got the cooler all done except for the drain and im going to cover all the foam with cloth to make it durable as the adult beverages are banging around in there. it is contsructed of 3/4" home insulation foam with 2 layers on the bottom. polyester resin ate up the foam so i went back to west system epoxy for this. I am thinking about just drilling a 1" hole with and a rubber drain plug like my original one was. here are pics of the completed cooler.

This is where i am at with my floor modification. this portion of the floor is not really going to be stood on too much as it is right next to the console. so it will be filled up with plywood and 1.5 oz mat.

any comments are appreciated as always.

i got the section of floor fully glassed in today.

luckily the boat is in the shade as it is 90+ degrees in miami today.

i was tryin to use some west system with 206 slow hardener on my cooler today but since that is sitting in the sun i think it triggered the reaction too fast. the mixture started smoking and started the melt the container i had it in
