I have quite a few patents. Its been a fun exercise but I don't think this one is worth the investment in terms of patent. There are a lot of solutions out there but none are specific to FC-470's so...

Doh! I finally see what you're saying. I can't believe I haven't caught this until now. Of course the adjustment level is limited to the range of that slot otherwise I would have to drill more holes...

I addressed the bolts that were too close to each other. As is there are 6 x 3/8" bolts going through the transom. Is that sufficient? If I go up in size it'll interfere with the adjustability...

Here's where I landed. Thanks for all the input. At 0.75" increments with 3/8" bolts there will be enough distance to fit a open end wrench but not a box wrench or socket. At 1" increments you can...

The ones in the CAD model are 5/16". Too small? I use larger ones for the ones that don't hold the motor down as I am limited by what can pass through the motor mount holes.

Thanks! I like the idea of 0.75" increments. 0.5" seems small. You mentioned +0.25". Would you really want the AV to be slightly above the the hull on a Zodiac?

I don't know what he has other than judging from the picture it looks like about 0.5" below the hull.

Determining Shaft length on a Zodiac FC470

I'm considering making it adjustable with 3 half inch steps. What height do you think should be the neutral position? Should the neutral position be flush AV plate/hull or 1" below? I know on a...

Thanks for the input. My AV plate is currently 4.75" below the hull. If I raise the motor per drawings (4.375") it will be 0.4" below the hull. I suppose I could have it slightly lower (0.75" below)...

So you're saying that at neutral trim (meaning boat is on a plane?) the AV (Anti Cavitation) Plate may rise an inch? So in that even I should probably reduce the overall height of the riser plate by...

The clamps should fit as the opening is closer to 2.75" but I will of course double check to make sure. I'm not sure if I have the height dimensions correct. As currently measured the cav plate is...

Transom Riser Fabrication

I have decided to design and fabricate a transom riser. So what is the optimal location for the cavity plate on a Zodiac F/FC-470? Is it exactly flush with the keel or is it 1/2 - 1" below? If it is...
