Suzuki DF90 offset
I will be fiting my new DF90 to a 5.8m Destroyer hull at the weekend, recommended offset by Humber varies between 1" and 1.5" to starboard (it depends who I asked ) Any other thoughts on how far offset, if any, it should go?
It has a centre console and twin seats so will be slightly heavier to stardboard on the very few occasions it is out single handed.

That sounds good to me. We would go 1 1/4 inches if we fitted it but you should consider if you may upgrade to a bigger engine, If so I would go 1 1/2 inches now.

good luck with the new engine. Is that a new destroyer or just new engine on same boat?

Still not decided on seating, probably two extreme pods from Humber unless something better can be found.
The old boat was sold last december. Build thread starting on usual thread with pics.

Had yet another suggestion today from local riggers saying no offset at all. This means depending on who I ask from the local riggers to the manufacturers I get a different answer ranging from 0" to 2.5" to starboard.
My last boat and outboard were small and light enough for the motor to be mounted centrally without problems but these are a lot bigger and heavier and I don't want to drill any more holes than necessary, any thoughts? I intend to fit it at the weekend, weather permitting so I still have a few days grace............

The larger the boat the less important the offset. Go for 1 inch and you will be fine

1" to starboard is what I am thinking of but as usual the thought of drilling the first holes in a brand new hull is a bit of a spincter tightening moment.
I know from my last build it gets easier after the first few but still...........

Drilling holes in a boat is always a problem for me. Just finished chain drilling a 4 inch hole in my deck to mount a seat. Still sweating.

My DF 90 on my old 5.8m rib was offset by 1" according to the manufacturer. I never measured it so can't confirm whether it was or not. I never noticed any handling issues so it must have been ok.
