"Jason thanks for giving us the results. That is great news for your boat to be more efficient at cruise because thats where most of us enjoy our boats. It sounds like your boat is running more level at speed so it may even improve in rough water…"

"Hi Rick I picked up only 2mph at cruise and my top speed has not changed. It tops out at 46mph at 5000rpm. I'm using 3 blade 19P props and don't expect much more out of it. Perhaps after I refresh the engines as they have 700hrs on them…"

"Jason glad to hear you were able to do the swap. I had a feeling it would improve speed and better fuel economy. How much speed did you gain at cruise and top end. Did you notice any bad boat handling with the swap ?"

I've had the boat for almost 2 years now and love it. This year was a refresh of the engines. Next year will be a coat of paint and other cosmetic items.

Hi Rick

I picked up only 2mph at cruise and my top speed has not changed. It tops out at 46mph at 5000rpm. I'm using 3 blade 19P props and don't expect much more out of it. Perhaps after I refresh the engines as they have 700hrs on them they spin up a little faster. 

I'm heading out again tomorrow and will double check my top end speed.
