Allison Grand Sport Performance Update, Quick Take Mercury 150, 80 MPH

We do a little update on the Allison Grand Sport with a Mercury 150 four stroke. This is a quick take to go with our article. With a 30" ProMax prop, we achieved 80 MPH. Cruises at 70+ MPH at 5000 RPM. Find the details at www.wavetowave.com

My husband and I have a 2003 w the new pro xs 150 . Running 71 w 26 trophy. Don't really miss the old 280. (Can hear the sound system now)

How is it getting on plane with some weight in the boat with that prop? Say a passenger, cooler and gear for the day at the sand bar?

Pretty good. I've run it with 5 people and a cooler with a 28" and it was pretty good.

Hi Any idea of boat weight all up without driver and gas? Another aspect that really interests me as part time boat builder is planing surface detail forward of transom. Obviously important intellectual property and not easy to photograph
