I am now a 7M owner.

Willard 730.

Took delivery on Friday, but had friends in town over the weekend, and couldn't go out on it.
Had yesterday off, and just took it to the local boat ramp to get my trailer dialed in. Where does your boat sit on the trailer? I am around 5 inches off the back bunk. Should I move it forward? I was trying to avoid this, because I have to back the trailer further in to the water.

I'm presently keeping it on a trailer in a ghetto parking lot, so I remove the propeller, which is pretty easy. I went to West Marine to purchase another retaining clip for the nut on the prop, and they never heard of a Konrad outdrive. Thought I could possibly use a Bravo II, but they had none in stock.

I'm towing with a van that has a turbo 7.3 diesel, which handles the load just fine.

A little surprised that my tubes lost air over two days that it was parked, so it looks like I have my first project.

Hope to go out next weekend, and post up some good pics.

Chris,

Yep, I had all new brakes, master cylinder and bearings installed prior to purchase of my new boat.

Do you have a pressure gauge?

Yes, I do have a gauge, but never use it.
This is my fourth boat with tubes, so I think I have a pretty good idea on where o need to be for air pressure.

Famous last words before someone brings me a boat with the rear underside seam ripped open due to underinflation...

Use the pressure gauge. Monitor the air leakage in each chamber. A 10% loss in 24 hr with an old hypalon boat is normal (or 20% sometimes!). For welded PVC / PU, then I'd say a 5% / 24 hr loss is acceptable.

Yeah, zip finally got a 7m!!!!

I'd check the balance on the trailer and tongue weight. I'm still working on mine but I have the OB on the back so it's really screwing things up. I think I need to move my axles back but I'm not sure how much. Generally I think it's a good idea to have the transom on the bunks although there isn't as much hanging off the back of yours.

Well done with your new purchase and I am sure you will have great fun. I am not too thrilled about the console but that is me. Will you be replacing it in the future?

If the boat hadn't been out in a couple of weeks, the tubes always required some air. If I was taking the boat out early in the morning and I had been out recently, they usually just needed a top off. If the boat had been out recently and I was later in the morning, they tubes were usually pretty full and tough to top off with the foot pump I had.

Congrats, Zip.

Are you saying the transom is 5 inches behind the bunks? If so, I'd say ideally, it needs to go forward (the "ideally" part due to the heavier construction may be able to handle that - most boats wouldn't. Also, not sure what the inboard does to stresses; would expect that it reduces the mass hung off the back by a good amount.)

As far as how deep you need to go to launch, maybe rollers on the front third of the support area? As the back of the boat floats, the rollers come into play. Something I've thought about for my trailer, but I'm not sure I could control it when launching/recovering solo, so haven't pursued it.

Anyway, get that thing out on the water and get us a report with pics.
