out bord on drawbar and weight factor ?

Hello all ,I have a 15 Hp outboard motor it weighs 42 Kg and I have it towards the front of the draw bar on a cradle that I made which use to work great with the old 6Hp johno but now has caused me a bit of grief with the motor hitting my swing out jerry can holder on the back of my cruiser resulting in breaking the tilly arm on a brand new never been used motor when I turn tight so now I'm thinking of a 100 x 50 x3.0 RHS up against the front of the van going across the draw bar in the centre I will remount a bike rack in the centre and on the ends I will make a pivot arm like what I have on the cruiser with a latch but instead of mounting a wheel or jerry can holder I will have the out board on the drivers side and on the pass side I will make a cradle for the fuel tank 25 LTRS max so what I am asking is am I putting too much weight on the draw bar or for that matter the back of the 100 ser toyo? I need it to be able to swing out because I have a Windsor Rapid and the beds fold down and just to fill in the gaps I have a tinnie on the roof of the cruiser and I have a fold up trailer on the back bar of the van near the spare wheel , I hope I have given you all enough info LOL! thank you all for taking the time to read this and I hope to read some feed back soon.

Regards J.B.
