This thread has drifted from whether a cruising
boat with an OB should leave the motor in the
water when anchored to whether a dinghy dock should feature motors tilted up. Two different issues: one practical for the life of the motor; one etiquette.
There's a giant thread on dinghy dock etiquette already on this forum.
I find the OP's question interesting as one of the boaters whose big
boat has an
outboard: we're a small subset of the cruising community, and some of us prefer to have the OB always up unless it's on, while others leave it in more than not, or even have it idling on standby in a tricky channel.
There's a comfort to knowing the motor's already in the
water and just a pull of the cord away from getting you out of trouble when sailing up a narrow channel: I have to do a double gybe in mine, barey twenty feet from people knee-deep with
fishing poles, no room to bal out, and a heavy
current.
On my previous boat the
engine sat in a well and could never come out: I hated that, since it slowed the boat down and made the zinc hard to get to. Still, it stayed nice surprisingly long. I doubt it would have for the 14 years of hard use out of it that I got from my other one that DID come out, and had no damage alow before the powerhead died.
