Martin not got one for sale but have to plug the Fich 115 .I have one on a 5.85 Ribcraft really good engine .I am at Alton if you want to see one or try it some day . #
Personally Id advise you on the Optimax. I have run these, Fichts and four strokes. I bought and still have one of the first 135hp Opti's and it's now done hundreds of hours without hiccup. All the others were good but not quite as good.
