    Bought wrong prop

    My son hit a rock and dinged up the SS prop on 217 ChrisCraft Concept 5.8 OMC outdrive. I was out of town and he felt bad about it so he ordered a replacement online (no return policy), same 14.25x19, but has pressed in hub instead of quick change hub, and it seems to be from a Mercruiser from...

    Thanks for the replies. Great information in the manual. I can get the boat in to get it checked in September, but the date slipped due to high demand. Reading thru the manuals and trying to test things as best I can. Without a code reader I'm shooting in the dark, but did try a Coolant temp...

    Understand not OBD1. Reading thru manual its OMC MFI. A specific code reader. Still struggling along, checking sensors. MAP, IAC, TPS, Fuel Pres Reg all seem good, no fuel in reservoir vent line. Guess I'm stuck waiting for shop to get an opening. Thanks for the replies.

    Thanks for manual download, that will be very helpful. Checked the float today, works great , cleaned needle and seat. I have an OBD-1 Ford code reader, it's pinned differently, all I get is steady tone. Anyone use a test light or multimeter to get codes? If I knew which wires to hit I could...

    Red button above fuel separator?

    Checked the battery, has fuel in tank, checked kill switch. When I get back to it will check for spark and fuel pressure. Also will change fuel filter seen in photo. Just can’t figure what the red button is for.
