    Mercruiser 4.3L - Stumbles at 3000RPM

    The Carter OEM pumps can be had for like $70. But I went through 3 of them before getting one that put out the correct fuel pressure. Possible you'd be replacing a bad part with a bad part.

    Mercruiser 4.3L - Stumbles at 3000RPM

    Did you check to see if you're getting a stream from the accelerator pump when you stab the throttle? And I'm confused about the symptoms. It now only hesitates on muffs? Last, did the symptoms get immediately worse after changing the plugs?

    Stupid me, no oil

    That didn't work either. I pulled the flywheel housing back off; doesn't look like there was a spacer on the other side, but I took the new one out, put the spacer in, and now the bottom of the mount extends a good bit below the flywheel housing. Definitely doesn't seem right, and much more...

    Stupid me, no oil

    Well, might have screwed up. When I pressed in the new mount, I'm not sure if I installed the spacer or not (pretty sure not). Can't tell now. Engine is in the boat, but not hooked up. Do I pull it again, order a new mount, and cost myself more time now, or finish up and see what happens?

    Stupid me, no oil

    Finally got that RMS swapped. The old one looked good, I don't think that was the leak. Unfortunately I think it was probably that line from the remote filter. Which would have taken 5 seconds to fix with the engine in the boat. Still nice to have everything cleaned and painted. We're getting...

    Mercruiser 120 poor starting

    Missed that part. Still, I'd focus first on the certainty of no spark than the who knows of the fuel at this point. But yeah, for sure check the float drop if you have the top off. OP, if you have a snappy blue spark on a plug at the end of the coil tower wire, that should be enough to fire...

    What's behind this plug? 2001 4.3L

    Yes! That's what that other one is for. Thanks!

    What's behind this plug? 2001 4.3L

    Cool, that's what I thought. There's one above it as well, couldn't remember which was the cam.

    What's behind this plug? 2001 4.3L

    Finally got the flywheel off on my slow motion RMS replacement. Found a plug just above the crankshaft that's ferrous (others on the block were brass already). I don't think its a water passage but want to make sure before I button it back up.

    Snapped seat bolt

    I've got 235k on the clock and beat the everloving crap out of this thing. The seat was $35, switches were $20. New plugs and wires last year were $50. Free oil change won at a flying squirrels game. Antique tags, no inspection or license fees. New drums and shoes 2 years ago, $50-100. Total...

    Snapped seat bolt

    Not sure. That's what would keep me from just running a tap through it. I don't think the gripsert would work, it would need to keep from tearing the sheet metal in a crash. Yeah, check out the seat. Pretty sweet, right? It's heated but someone swiped the switch. The wiring was different, and...

    Mercruiser 120 poor starting

    He's got fuel in the accel pump well, and that's a good amount in the bowl. If the pump squirts fuel, looks good enough to run to me... Sorry for the confusion, but looks like you have spark to the coil, great. Are you getting it at the plugs? If so, great, we're done (probably). If not you...

    Mercruiser 120 poor starting

    You may or may not have 2 problems, which the parts cannon may or may not have helped. I'd start with spark first. The points system is pretty simple. Ignition on, there should be 12v at the coil pos. Coil neg will be either 12v or 8ish depending on whether the points are open or closed...

    Critters in My Boat

    I'm going to take the opposite route. I leave my boat loosely covered with the sides open. Unless there's a real driving rain (and Im parked next to a building on the usual windward side) it doesn't get wet. Doesn't get mold. No critters because I think it's too exposed for them.

    Mercruiser 120 poor starting

    Not sure what you did with the points? Replaced, set dwell? You have voltage at the coil?

    How do you pin point the source of a loud vibration

    1. Drain the oil again/pop the cap and see what you got 2. Pull the drive and start the motor to see if the vibration is still there 3. Did you check alignment?

    Snapped seat bolt

    The front seat in my '97 ranger (which I swiped from an explorer 16 years ago) are worn enough now that the springs have cut through the foam. Back to the junkyard and got another "new" one. One of the bolts (out of 4) holding the frame to the floor snapped off. Against my better judgement used...

    Free boat with history of leak... worth it? Will a survey catch issues?

    This. None of the guesswork of a moisture meter, easy and foolproof
