That 550 chamber will probaly hurt it a little. Those engines are 650/750 style engines. I'd try to sqeeze a 650 chamer in that hull. Should rock then . These engines were rated at 90hp , but that was with all aftermarket PJS stuff.
Is it a reed cyl? If so it's most likely 700 (80mm bore 650 crank). It's an OK engine , I have one , comparable to a 750 Kaw.

In a 650SX with a single 38 and...
Replaced the 9-17 skat impeller and stock reduction nozzle with a 11-19 skat and a nozzle bored to 82.5mm today. Scotch brighted and washed the pipe , installed a second 500gph bilge pump.
The Mrd has hit a little snag on this engine. The PJS Viper motors use a nut to hold the flywheel on...
Well after pulling the stock 650 out of the X2 yesterday I found out where my X2 hull needed fiberglass. The left chine has a fist sized spot that was crushed and repaired with some type of liquid nails type material. I ended up fiberglassig the entire bow from the back of the battery tray...
