Robalo r24 performance

by Tony
(Oakdale ny USA )

I hVe a 2007 r24 robalo with twin 150 Hondas. The boat cruised only at 23-25 mph. Two years after trying to find out why it is so slow I was told it is a very heavy boat. As fate has it one engine corroded internally . Overpowered with twin 275 suzukis and I am having cavitation problems and speed problems again. Does anyone know what the cruising speded and max speed should be and what size props should be correct. Also the Hondas were sll the way down on mounts and my mechanic put the suzukis on the middle hole. Is that the correct hole for the mount. Thank you
