I haven’t seen anyone post with that combo. I read an article online about a guy in Australia running it with dual power poles, but I can’t recall performance numbers. Personally, I think the Sabre looks sharp with a G2, and I would guess mid 60’s solo. I’m sure BCB has run one empty. Maybe they can give you an idea.
I’m really impressed with mine. My last rig was a Puma, and aside from running big rollers, I enjoy driving and fishing from my 18 footer over the big boat. It’s incredible fishing shallow and running back water areas, and I still haven’t gotten wet running big water. I’ve got the 175 2 stroke, and I get 68-69 solo with any prop I’ve tried. I wouldn’t trade it for any other 18 footer on the market.
