My father and I enjoyed success with his new 350, however, the Cobra drive didn't fare too well during our maiden voyage this weekend.
The upper oil reservoir (where the dipstick screws in) was dry after we experienced and engine stopping "bang" while coming up on plane. Once back on the trailer, the engine wouldn't turn over when bumping the starter. We then filled that same upper reservoir (on the Cobra) the engine turned over. Next we went back to the lake where the drive operated fine, but after 1/2 hour a noisy "gear/bearing like whine" all of a sudden appeared. She only makes this whine when in forward or reverse.
We wonder if the long cold Wyoming winter froze leftover water in the drive/pump housing and split something in there. The drive is coming off later this week for inspection.
My questions:
1) Where is the shifting mechanism in the unit? (it's not a cone clutch)
2) Does the lower leg of the Cobra drive utilize a seperate oil reserve as opposed to the upper section?
3) Does the lower leg of the drive separate from the upper, like a Volvo or Merc.?
We're pretty sure the damage resulted from the lack of oil in the upper portion where the dipstick was.
Any insight would be greatly appreciated.
