I have a 1995 Dynasty Jet Storm (15'6") boat with a 90hp Jet Sport powerhead/pump installed in it.<br /><br />Does anyone know if there is a new powerhead/pump built that matches the dimensions of the 90hp jetsport - like the dimensions of the powerhead-to-pump area and the dimension of the ride plate, and ride plate to powerhead, etc. <br /><br />If possible, I would consider buying a newer unit, such as the Mercury 175 XR2 or perhaps something else, and retrofitting it into my boat. Also, does anyone know of a shop that can do the work?<br /><br />Thanks for any help thats profided, Dave.
