Had the same issue as you....got a converta ball with a built in rubber cushion. Into year three and no issues. I've taken the tin off the underneath of the fifth to check the frame......no cracks or distortions.
Just wanted to share with any other Yamaha generator owners out there that Pinellas Power Products has developed an awesome 4 button remote control kit for the above unit.
I had been tempted to get the factory one from Yamaha but then discovered that by installing one of these...you will disable the manual choke, add to that the off/on off/on start procedure.
Pinellas kit is a tad cheaper than Yamaha and not only offers a remote on/ off start but also change the ECO switch remotely as well as being to operate a 15amp circuit remotely......all with one unit!
Simple plug and play install.....nothing too difficult for the average guy. Takes about 60-90 minutes.
The remote range is over 400ft as opposed to Yamaha's 75ft or so.
Needless to say I am very impressed! Now no need to go out and start the genset......Life is good!
We camp for over two weeks at a remote lake in Northern Saskatchewan. Soooo glad we have a generator. Purchased ours after the second year of RVing and havnt regretted it. Big enough to run the AC or MW and HWH.
I store farm equipment over winter.....and unless I'm going to use it during the winter....nothing gets put in. Have a truck that has a CAT 3116 and it goes into storage with summer fuel in the tanks. It comes out in the spring and fires up first turn of the key.
I bought a nice one at Costco. Bigger than most and a very realistic flame. It also has a cover and carrying strap. It was about $80 - sorry , forget the model.
I couldn't be happier with it!
CAMP CHEF! We have one too.......awesome!
