I bought this boat (97 Speedster, Twin 720's) in February- I'm a Newbie to boating - June had all 4 bolts on tuned pipe/exhaust break - shop repaired, then only a few trips out 1 broke again! Mechanic seems to think the engine and pump are out of alignment causing the stress - any takes on this theory? any idea's of other issues (less expensive!) that could be causing this? I'm all ears . . . not too thrilled on the money this jewel is costing me already . . . and I do love my boat . . but really !
