    Does anyone know what this part is?

    Idk, I'd be nervous if I found a bone saw in my boat.

    470 3.7L Misfire

    No. Your carb dumps all the fuel into the intake. Wouldn't cause a problem on 1 cylinder. Agree that I'd pull the valve cover and check that you don't have any bent pushrods and the valves are opening correctly. I'd also reinstall plugs and put a timing light on it. Make sure you're getting a...

    Info on Mercruiser 0A494867 170Hp engine.

    Head over the restoration forums here. However, if you have rot around the engine, there's a very very high likelihood that you have rotten stringers +/- transom in addition to the floor. Unfortunately, this is a major undertaking. You may want to consider whether the boat is worth the...

    Out drive leaking.

    That's if you stop for a beer in the middle

    1994 Mercruiser 5.7 timing issue- no purple/white wire

    No base timing mode on TB IV, just set it at idle.

    2000 Sea Ray 5.7EFI alpha 1 gen2

    I suppose that the outer ring can't be the race since the rest of the bearing gimbals within it. I'll admit that I haven't disassembled one

    2000 Sea Ray 5.7EFI alpha 1 gen2

    IDK that it's bull. I've never seen a bearing replacement that didn't call for the race to be replaced with the bearing. They're always a matched set. Will it work ok without doing that? Maybe, but I've never seen an official source for any bearing that recommended mismatching

    What can cause this to shift bellows ?

    Yes, if your drive is trailered in that pic. The bellows needs to stretch as the drive is raised

    Not exactly. More about which way the bearing should face, and the reason why mcm specified a direction. And specifically whether installing it "backwards" would have an impact on function

    Mercruiser 3.0 fuel delivery issue

    Not sure where you're putting the hose, input side of pump and then disconnected carb? And that flows, but when input side of pump is connected to tank it doesn't flow anymore? If that's the case, you have a restriction between the tank and pump. Either anti-syphon valve, in tank filter/sock...

    2000 Sea Ray 5.7EFI alpha 1 gen2

    But should be able to seat fully and will function normally either way with either bearing, right?

    2000 Sea Ray 5.7EFI alpha 1 gen2

    I thought they could be installed in either direction, but MCM specifies the direction so that you can't just remove the inner race and bearings, you need to replace the whole thing.

    Mercruiser 3.0 fuel delivery issue

    Nor a glass inline filter. From what you're saying though, either bad fuel pump or restriction before the pump. I'd start by checking fuel pressure though. If you run on a remote tank and the motor works when squeezing the bulb I'd guess fuel pump.

    3.0L hard starting when warm

    Ok, I'll take a stab, but I don't have the actual wiring diagram to look at (@alldodge ?), so making a few assumptions, correct me if those are wrong. Also, one of the assumptions is that the 3.0 still has a mechanical fuel pump and doesn't need the diode and fuel pump connections? 1. You...

    What can cause this to shift bellows ?

    agree it looks twisted/stretched. I can't see any clamp or tie on the aft side? Also possible if there wasn't enough slack left in the bellows it could stretch it when you tilt the engine. I'd think less likely rodent damage since it looks deformed in addition to the holes

    Dry carbon fouled plugs 120 hp mercruiser

    Depending on your electronic conversion you shouldn't need a resisted coil. Also, have you checked to make sure your choke is opening fully?

    Not easily. Did I miss what the issue is with the current motor?
