I want to give a like for the pic, but a thumbs down for going into storage….
A suggestion in your quest to hit 50 with that load in the boat… Go out and make two speed runs up and back, record your speed and rpms. The pull your air filter elements and make absolutely sure the air boxes are clean. Start the boat and let it idle for roughly ten minutes to let the ecu adjust, then do two speed runs, up and back, record rpms and speed. If there is an increase you will probably benefit from getting a set of RIVA K&N style air filters. In my boat with its TR-1 engines I picked up roughly 200 rpm at altitude, everything counts to the left side of the decimal point!We got out yesterday for the first time in about 8 weeks. Air temperature 59 degrees, water temperature 61, wind 5 - 13 mph. It was chili, but it was good to get out for a couple of hours.
Side note, top speed yesterday 49 mph. Two people, gas tank almost full (90%), cooler and normal gear. We have yet to hit 50 mph, but I still believe we can get to 52/53 mph under the right conditions.
First time out since changing the oil (52.5 hours on both motors) about 3 weeks ago. Spark plugs will be swapped out as soon as I get a chance. I will give your suggestion a try but will likely have to wait until late February early march.A suggestion in your quest to hit 50 with that load in the boat… Go out and make two speed runs up and back, record your speed and rpms.

There is also one other trick that could make a difference, turn on your bilge blowers while making extended speed runs and see if you pick up any rpms…. Makes a slight difference on my boat, one of the many things on the list is to figure out how to get the coolest air into the intakes without sacrificing water proofness…
The colder and less humid it gets the more hp your engines are going to make.
