Hi. I am new to this forum and Seadoo boats. Baught a 2002 Challenger 1800 last year. Perfect condition but had no engine( Mercury 2,5). All the rest is there (ekshaust, jet, wiring). Need to buy an engine. Lives in Norway and it seems impossible to get an engine for a reasonable price here. Would it be smart to change to an other enginetype or stick with the original ? Would be very thankful for any tips where to get an engine for a ok price.
