Hey Brian or anyone else. Happy Friday. Im starting on my transom now and revising the plans. I have decided to go with the standard design and for a single main motor. Should I consider a small offset to the main motor? And why would I do that? Is it to counteract torque or to address the kicker weight? What are the downsides of an offset? Maybe theres already a thread...

The only real downside to having an off-center motor, especially if you raise the motor a tad since the deadrise goes up, is that you can get some cavitation when turning hard (usually when going slow) towards the opposite side... if that makes sense.  No real reason that I can think of to mount the motor off center.

Took the opportunity today to put new heavy casters on my platform. These should do the trick. Molds go on tomorrow and If all goes well Ill get the bottom zipped together.

Looks like the legs on your fixture are long.  I set mine about as low as I could and the edge of the chine is plenty high.  If your tall it could be okay.

I don't have the plans in front of me but Brian does call out a height for the jig to be off the floor. You might also add a few inches if you are raising your sides up past the sheer shelves up front. If you go much lower on your jig you may not have enough height above the floor where the sheer shelfs meet at the bow while its upside down. Leave yourself a way to get under the hull while on the jig you will do it a lot. You will have a few new bruises on you head and your shins!!!

Thanks guys. I did the height that Brian recommended in the plans, plus 2 inches. Im 63 and will build a scaffolding like Chuck did when the time comes, if needed.

I made good headway today - got the molds on and the bottom unfolded. Video to come!

I was able to stand up under the boat while mine was on the jig.    Very  useful.   I then lowered it 12 after the flip

Lowering after the flip sounds like a good idea. Ill keep that in mind. Thanks!
