I. Introduction: Rome Before the Fall [click here for a brief overview of Roman history] After nearly half a millennium of rule, the Romans finally lost their grip on Europe in the fifth century (the 400's CE).
The 1989 SeaDoo SP featured a two-stroke, two-cylinder 587 engine with rotary-valve induction and a water-cooled exhaust system. The 587 jet ski used regular unleaded gas and SeaDoo oil injection. The bore and stroke was 3 inches by 2.5 inches and the compression ratio was 5.9 to 1.
Older models like the 1995 SeaDoo Speedster still turn heads today. You can find plenty of examples of the 1997 SeaDoo Speedster, as well as newer models, on sale as part of the large inventory on eBay.
