First ride in Ribtec 890SX
Finally finished getting it back together and took it for a 15 minute run in Botany Bay.
The photo is at our local boat ramp with Sydney Airport in the background.
With just two on board and one third fuel, the Yamaha diesels would jump to 4000rpm instantly. From memory that is redline, so we backed off to about 3200.
As there was hardly any weight in the boat, the nose is really light and the tail with twin diesels is really heavy. With any trim at all it just porpoised. Maybe we should try some different props. Currently we have the Hydradrive 21 pitch four bladers. They are quite a large diameter prop. The spline looks the same as the Mercury sterndrives and we have lots of props to suit, so may experiment.
Unfortunately the GPS hasn't been hooked up yet, so no speed updates. Will get it going before playing with props.
