So i've had a surging issue on my 97 330 SS with 7.4L MPI motors. left motor idles fine, but when it gets to 2500 or 3000 RPMs it surges, dying occasionally. i've had our mechanic out troubleshooting, and we were getting low pressure. my initial thoughts were check and replace lines, check and...
hi all -
long time lingerer, first time poster.
Bravo 3 drive, mechanic says might need a cone clutch. the right motor doesn't like going into reverse, goes into forward just fine.
boat is a formula 330SS, 1997. apparently with the pre-2000 bravo 3 drives you can no longer just get a cone clutch...
anyone know where the ASV is on this boat?
still having issues with lack of WOT RPM, and some surging down low on accelleration. figured i'd check this before digging into the carb.

long story short, recently bought a Formula 330SS, so i'll be getting rid of the Formula 252BR. took it out last weekend, boat doesn't want to get over 3600 or so RPM. i've read a few threads on here, but wanted some input on what else i could potentially troubleshoot.
Current plan of attack...
