Well we are busy at the shop even with it being off season, lots of winter projects, jet-drive rebuilds for both ski and race and we are plugging away on our CP tunnell project as time permits. We are looking to build a really nice race boat here, goals being a clean, well thought out layout and easy to service. So here is where we are at with our transom plate assembly.
What we did here is build a 3/16" aluminum plate that is mounted to the transom through the backing plates you see here using 10-32 screws, the plate is drilled and tapped and sandwiched on the transom. This plate is permanent and will not need to be removed to remove the jet-drive. We chose to build the backing plates rather than stringer washers for a different/unique look and it spreads the load out nicely.
Here we used .090 6061 for our removable plates, these are mounted with some 8-32 bolts. The 3/16" plate is drilled/tapped so to remove the jet-drive, you just remove the 8-32 bolts, pop the plates off and remove the drive. The bolt heads coming through the 3/16" plate will be flush with the plate and will give a nice clean look to it, these photos were taken part way through fabrication so things are still in mock up.
Pictured is a dominator 12 S suction that is bored for a pop off and double drilled for extra clamping force.
-Got some color on the TA plates.
-The red and black look real good together.
