All Davit Owners Please Post

I purchased a new Zodiac YL310 R & a Yamaha 15 hp 2-stroke last spring (replaced the 15 hp with an 8 hp Yamaha/2-stroke........ found the 15 to be too heavy to remove and the faster speed really wasn't a priority for me). Spent the summer checking out mounting systems at marinas and speaking with other boat owners., as well as a lot of time on the internet

Really liked the Nautley & Hurley systems (even spent quite a bit of time looking at the St. Croix roller system, but my platform isn't wide enough). My main concern was about backwash when coming off plane and also how the inflatable would ride when in a big following sea.

I have finally decided on a mounting system and am having my dealer install removable Weaver brkts to my swim platform, pad on bow of inflatable and brkt/arm mount for the stern. Will also have stand-offs installed. My thinking is that with the stern bracket/arm mount I can purchase the Weaver motor bracket at a later date and leave the motor on the dinghy if removing the motor becomes a hassle. The stern bracket mount is more substantial than the pad mount. To pull the inflatable up I might go with a block & tackle also (like a Schaeffer or Lewmar boom vang.....I'm an old sailor).

I also like the fact that the inflatable can be attached to the plaform when boarding and exiting the dinghy........stable & safe.

Max, I have been using the weaver motor braket for some 5 years. It is infact really convenient as you will never remove the engine again, but... it destroys the dinghy's tube. When the dinghy is stored vertically, the engine weight is completely pushing on the lower tube. The joint between transom and tube is really stressed and will come apart very soon... this is why I will go to Nautley or Hurley as soon as I will have the new longer platfom installed.
 
Pietro,
Thanks for relating your experience regarding the tube. One of the reasons I switched to the 8 hp Yamaha is because of the lighter weight compared to the 15 hp (19# less).
I'll probably remove the motor and stor onboard when I travel
 
I think I posted this earlier on this thread, but I have the Nautly Dinghy Ramps and have had them for three years now and they have held up very well and works great with my
8' 11" Mercury air deck w/9.9 hp outboard. I had to raise my dinghy up an inch or so to clear the dual platform on my 330, I replaced the small 2" rollers with some 5" neoprene trailer rollers and it works great. I am thinking of putting a small electric winch in the trunk to hook on and pull it up, not that I am that lazy I just thought it would be cool....
 
I asked Sea Ray about "Engine Waterline Height" and got the following reply, so I thought I'd share (got their permission):

"Basically, there must a minimum clearance between the water line and engine riser height. This helps prevent the possibility of water intrusion into the engine. This clearance will generally be around 13-15 inches (waterline to top of riser), but will vary depending on the engine size. The boat is designed for normal weight ranges that will maintain this clearance, however if heavy items are added onto the transom this could under certain conditions, reduce this height creating the potential for damage to the engines. Naturally, this will be dependent on the amount of weight and conditions."

So basically this is SeaRay's way to CYA, and if there is a water ingestion issue with your boat because they didn't provide enought water height, and you added a dinghy which will only weight as much as a small adult, then your boat is no longer covered under warranty. Got to love they way they tip toe around everything and make it your fault they can't give the engines another 6" of water height clearance.
 
I have a set of Hurley Davits and they are great for my boat as I don't have a high swim platform

does anyone have the nautley system? if so do you know the measurements of the arms that extend out to receive the dink? any info would be appreciated
 
I have one of the original Nautley Davits, they make a few versions. Which one are you looking for? I have the Dinghy Ramp HD, but they also have the Dinghy Ramp XL..
 
we have the same boat and my ding is 9' i was thinking about the dinghy ramp hd also if you think its ok on your platform? do you have any pics? whats the thickness of the material they used ? thanks
 
send me an email or PM with your email and I'll forward you the photos.. I've had the system a few years and it works great for me..
 
This is my setup. Weaver arm on the dinghy transom and pad on the forward side. Two stand-off bars one off the transom of the dingy and one to a pad mount. This setup is stable and allows walking on the platform. Pulling the dinghy up is a bit tough alone (a line to one of the handles on the outward side, but with two its easy.

Creek...What is keeping your engine on?

It works!!! I was actually doing the same. Then I bought a much heavier 4 stroke and I added a "leaver" (That's the special engine mount to tilt the engine).

As I said before, I had troubles were the arrows is pointing...

Well, i'm not crazy about that set up for three reasons, 1. cant see while backing into the slip and 2. the stress on the ding tubes from holding the motor even w/ the optional bracket it's not designed to be on it's side w/ weight on the transom like that. 3. i also dont like turning a motor on it's side the floats in the carb, the bowl and other parts arent sitting properly,(it just doesnt look right ) maybe im wrong i was told by pops never turn a carb on its side( i assume the outboard has a carb)
 
I am using the Hurley Davits. I liked the idea of being able to connect the 2 pieces together with a cross bar. Of course you can always remove it if you want but I thought the 'one' piece might work better. I like the davit, nice finish, easy to install and has a teflon or delrin pad on the metal framework to slide the dinghy on the boat. I will try and take some pics when I put the dinghy back on the boat. Sorry for not having any for you guys.
 
You can't see it in the picture, but there is a weaver arc arm that mounts to the transom of the dinghy on the inside and then arcs over the tube to clip on the davit. All of the weight of the stern of the dingy is supported by the thick stainless steel arm. There is no weight on the tube. The front end of the dingy is mounted with a regular pad mount, but the engine weight actually counterbalances and "unweights" the front pad. The only risk might be stressing the transom itself, but I doubt that is a problem since there is more stress when I am running the dingy

The engine is a Yamaha 8hp 2 stroke and is not that heavy. The 330DA doesn't bounce around at all at the stern and the dingy barely moves while underway so I just leave it mounted (and locked two ways).
 
Re turning the motor on its side. If you look it actually is mounted the way it would sit if it was laid down on the floor, which is the way a lot of them are stored when you others find a home for them on the boat while underway. I don't like the idea of putting a dirty outboard inside the cockpit while running and would not want it on the swim platform getting water on it.

You did right!!! I believe now, after my experience, that the weaver arc arm is mandatory if you want to leave the motor on!!! And with a 2 stroke there's no need for the leaver.
