    Default 280 Outdrive lower to intermediate housings bolts?

    Just getting ready to water test my repairs, and I found that one of the Allan head bolts is missing that connects the lower to intermediate housings. This one is located on the port side, closest to the transom. Hard to see because you have to look at the lower housing from underneath. I just filled it with oil, so I would rather not crack loose any of the other bolts for comparison.

    Who knows how long that's been out.

    What size are these bolts? I'm just going to try to find a stainless one locally.

    Part number 47, forward most closest to transom.
