i got this boat in march, all four carbs were properly rebuilt + standard tune up. other than the port motor never revving above 4k, both motors run and sound great. the boat accelerates very nicely from no-wake speed. also, while the speedo says im barely hitting 40mph (with only me in the boat, not even 35 with one passenger), i keep up with most of the skis out on the river, so that may just be a speedo inaccuracy (correct me if im wrong, but i believe i read the factory top speed is about 50mph). the only annoyance (other than leaving power on the table) is having to constantly countersteer starboard at WOT.
ive swapped the plugs multiple times and checked the throttle. id consider it being an issue with the motor itself, but this is a relatively new SBT motor (not sure how new), while the SB side is factory and fully revs. when i first got the boat, the factory SB was in need of some TLC, but the SBT motor on the port side ran like a champ.
the dirtbike/atv side of me is screaming high speed screw adjustment, but from what ive learned about jet boats, i believe its a drive issue. if it was a wear ring, the motor would still rev, it just wouldnt provide much thrust, correct?
therefore, my guess would be the impeller, or maybe the pump itself? has anyone faced and solved this specific issue? lmk if any more info is needed. thanks much!
