Df 90 on a 4.7 rib

[mandulamx]

I'd like to put a new Suzuki DF 90 outboard on a 4.7 Joker Boat(italian made,around 1990.Good condition) Is it stupid to do something like this? Would this engine be to heavy for this boat? I am planning to buy a bigger RIB (5-5.5 mtr) in a couple of years and it would be meaningless to buy one smaller engine now and a bigger then.Right now there is a Selva 55 HP 2 stroke (also italian made) on it,but I've had enough of the noise and smell and oil...
Thank you ...

I am pretty sure the max for that boat is around 50-60hp and wouldn't recommend that large a motor especially the weight of a 4 stroke on the back. Why not buy the bigger boat now?

See how this works (first time reply and in english, apologies for the spelling). I've got a Joker 470 with the new suzuki DF90, mounted on by myself. And I must say, it's a perfect match. The problem with the "old" outboards is not the power (the bracket is strong enough) but the weight.With this new design the weight is not the problem any more. However, to be certain, I've made some bars to the upper bolts and rib. I finished up some heavy testing onto big waves and it seems to be oke!
