Now on to the Hydrostatic pressure chamber test tank. Please note all the scientific equipment clearly in evidence and the numerous Diplomas casually displayed about the area.

Now on to the process by which I am trying to reduce the vibrations affecting the APC. I took a shipping envelope that has the bubble wrap applied to the inside. From it ,I cut a large piece and siliconed it down to the equipment tray. Then I took the APC and did likewise. When it drys it will be attached and floating on top of the air bubbles.

Got it in the water today. Yep, well definitely have to go with gear reduction. The 20 amp speed controls keep cutting out at anything above half throttle. That tells me that those motors will burn up. So, im looking into a 2 to 1 gear ratio, to start with. Details later. Also, Im going to follow Daves lead once again. Im going to buy me a kiddie pool. That way I can trim my two large subs at the house without a long drive.

Nah! That's soooo tacky. You'll have all the neighbors moaning about the thing in your yard:-)
Get a sheet of cheap plywood, and cut it into three long lengths. Make an 8' long x 1' 4" box and line it with some pond liner sheet. It will cost less, and take up much less room.

Now ... THAT's a good idea!

Make sure you brace it well- water will bow out the sides else.

Yeah.........but..........I want a kiddie pool..................................for me.

Needed to do a little work on the old style vent valve. I cant speak for the new style. Ill do what I did on the Oscar and it worked great. I drilled out the factory hole that was 5/32" and increased it to 3/16". In order to do that I had to remove the flapper valve. To re install it ,note that there is a chamfer on the front side of the housing and a built in chamfer on the flapper. Carefully make sure that whatever adhesive that you use holds those two areas together so that there will be tension pulling the flapper open when you hold it up. I used gap filling CA so that I could control where the CA went and could then "Freeze" it where I wanted. Just a little dab will do ya.

Just snap out of it will ya! You're supposed to be a man! Do I have to come over there and slap you around? Or worse, send HWSNBN?

Now on to gear reduction. The older style 3&1/2" Subdrivers came with outside mounted gear reduction units. I think that they are great because you can get right to them, and that allows you some flexibility as you will see. At any rate, they come set up for 3 to 1 gear ratio. Since we started out this mod with going direct drive, I think I will start from there and move up the ladder so to speak. From 1:1 we will go to 2:1 and note the improvement. The gear housings are mounted using screws that also hold the motor in......perfect.
Problem, you have to hunt for your own gears and also the center to center of the gear housing is fixed, so be prepared for some mods to the housing to make it work. Ill settle on a couple of gear sets shortly and Ill post a link to them.
