i took the boat to the lake and was overall impressed being the first time i have ever driven a boat and this is my first boat. i bought this boat 3 weeks ago and one of the engines have been replaced with a brand new one of the same kind. the new engine is the one i have a problem with. both start fine but if i accelerate slowly the new one wants to die right around 2 rpm's. i finally got into the habit of accelerating really fast to 4 rpm's which would work. i watched the gage and it would skip really fast from 2 to 4 rpms. i am just hoping i need to get it tuned but i was wanting some extra info before i take it anywhere. thanks:cheers: i have a 97 seadoo challenger.
