A 90hp motor on a boat may sputter due to several potential issues, such as fuel delivery problems, including a clogged fuel filter or a failing fuel pump. Additionally, a dirty or malfunctioning carburetor or fuel injectors can disrupt the proper air-fuel mixture, leading to sputtering. Other factors might include ignition system problems, such as faulty spark plugs or ignition coils, which can affect engine performance. Regular maintenance and inspection can help identify and resolve these issues.

Look at the manufacturers plate on the boat for max HP and or weight. If there is none either call them or consult a marine engineer or body and get a rating tag fitted. My two previous motors on my 16 footer have been 90hp and 115hp.
