    Anyone know what on my outboard this came from?

    If you post the motor's serial number, it will be possible to search for the exact parts list.

    Anyone know what on my outboard this came from?

    A helicoil wouldn't have a round cross section, it would match the thread of the hole and bolt. It wouldn't have needed to be removed if it was in a carb, either.

    stray current

    Are you testing this when the boat is on the water, or on a trailer?

    Kohler Generator

    Do you have a manual for this? Does it indicate what those codes correspond to? Pull the spark plug and try to crank it.

    Lower unit disassembly

    If the propshaft is rotated, where is the bend, outside of the carrier? What is the diameter of the circle formed by the shaft's turning center when it's rotated? Did you heat the housing? That worked for mine.

    Lower unit disassembly

    So, you removed the bearing carrier retainer and stainless tab ring, but the carrier won't come out? You're not trying to rotate it, are you? It has a small key that's meant to prevent rotation. Are you using a puller? It's supposed to slide straight out. I used PB Blaster around the perimeter...

    Alpha 1 forward gear needle bearing working out

    FYI- you can buy pre-owned tools for this, including real Mercury/Mercruiser brand. This saves a lot of money.

    mercruiser gear ratio

    If the engine has a plastic cover over the flame arrestor, it may also have a label with engine & drive serial numbers- if you have those (they may also be on your title), you can look on the Mercury site for info. They changed to a simple flame arrestor at some point, but this info was on that...

    Mecruiser 4.3 MPI Carbon Issue

    Did you notice a specific odor from the smoke? Did it smell like burning rubber? That likely means the impeller is toast and the bellows has been destroyed.

    Marine grade fan belts vs auto parts store?

    Make sure the pulleys aren't rusted and teh paint/chrome is smooth. If it is, either repaint after making them smooth or replace them. Do you see lots of black/dark gray dust in the area?

    Lithium battery on an old motor

    How much is teh battery? Add that cost to the regulator and decide if it's worth spending that much on an old motor. Do you need to replace batteries frequently?

    Should I change my engine water pump assembly as preventative maintenance? 2006 Mercruiser 350 MAG MPI

    If it's not leaking, I wouldn't worry about it- I recently changed the water pump in my 2005 Chevy Astro, at a bit less than 292K miles- unless the water contains sand/other sediment and/or is brackish/saltwater, it's going to last a long time as long as it isn't run dry.

    93' OMC 5.0 EFI - Struggling with hot starts, sagging drive and overheating at idle.

    If you run it normally/somewhat hard and shut t down, wait about 5 minutes before turning the key to ON (not crank). After that wait, check the temperature, but don't freak out when you see that it's around 200°F- it's normal, caused by heat soak (the heat lost by the hottest areas, gained by...

    93' OMC 5.0 EFI - Struggling with hot starts, sagging drive and overheating at idle.

    Open the throttle a bit next time it has a hot start problem. If it starts easily, check the resistance of the ECT (Engine Coolant Temperature) sensor- if the resistance is too high, the ECM will deliver more fuel than needed because the resistance and temerature have an inverse relationship...
