My Allison was sitting in my garage for the last 2-3 years covered up. I have owned it since 1999.I recently change a bunch of the filters, gas lines, impeller, seals, lower unit fluid, decarbonized, batteries, new seal for the trolling motor and plugs....... The Boat runs great with no issues. It looks like I have forgotten how to "string" that thing out? I was only able to get her to 82MPH and had to back off. Today it was 80 MPH? I use to run her all day at 87-88 MPH with no issues. Maybe I am not as brave as i used to be! Guess i have to relearn how to drive her?
