67/90 Hotsaw Rigger Setup

[happybradboating]

Some time back a few years ago I purchased a Hotsaw 67/90 Rigger and have finally started working on it at the same time as my 90% 67 SGX. In some respects these riggers are the same but the Hotsaw is a little shorter. I am thinking about spacing out the sponsons real wide on the Hotsaw like the 60/90 JAE hoping it would handle a .84 motor. If possible can someone let me know what the outside measurement is on the 60/90 JAE? I measured the 67 SGX at 15" 1/2" so I was figuring on spacing out the sponsons on the Hotsaw to at least 16" 1/2" or however wide the 60/90 JAE is setup.

Thanks
