1997 speedster twin 720 recent purchase
Boat will not plane
Left motor 4000rpm then cavitates to 7000
Right motor 3000rpm then cavitates to 7000
Motors good compression
New carbs new jet drive housings new props
New fuel hoses and valves
Intake side of motor new gaskets when I removed oil injection
All new pump housing gaskets and seals all properly torqued
New carbon rings and boots
No water leaks
Thoughts on next step
Reseal intake grates???
Not much tension on new driveshaft boot
Retension???
Thanks in advance
