    Where can I find the oil filter?

    if you can push it in to the end, and turn it with two fingers, you should be good. Removing it you are working against the suction from the grease. this is normal.

    Water in Bellows

    and next time you have the drive off, a straightedge check may be in order.

    1997 Mercruiser 5.7 EFI blown head gasket

    agreed, but with the age of the boat, I wouldnt rule it out freshwater either. Mine is older than yours, but still had the riser rot out that I had to replace. Not a lot of salt water here in AZ..... The Chevy head cracking issue is relatively common on automotive usages, so is an easy thing to...

    1997 Mercruiser 5.7 EFI blown head gasket

    check the heads real good. Chevys like to crack the heads around the exhaust valve, especially in the center two cylinders.

    1997 Mercruiser 5.7 EFI blown head gasket

    not uncommon for the piston to be "steam cleaned" when there is water in the cylinder. That is likely the root source of your failure. While we dont know yet where the water came in, it was certainly in #5. Had the other cylinder gotten enough water in it when running, it would be squeaky clean...

    Trim gage not working

    chances are, that the senders have fully packed it in on you. Thankfully they arent that hard to change on the Merc outdrives, but its a job best done when you are doing the bellows. the through hull fitting is above the u-joint bellows and can be a bit of a bugger.....

    Mercuiser 357 mag low compression on #6 (120 psi)

    And that’s 14.696 AT SEA LEVEL…. Not all of us live at sea level, so those numbers would be “high” for many folks that are inland and operate on lakes. My elevation is 3500 feet for example (pressure drops about 1inch of mercury per 1000 feet according to my search) sea level is at 29.92 inHg...

    Out on the Lake Pictures

    Yep, no “ring around the lake” this year!!!! That appears to be Schoolhouse where mine are at. The courtesy dock is about up to the top of the cables this year, rather than way down. According to the lake report, we have about 40’ of water at the end of the ramp at the moment

    Out on the Lake Pictures

    Yes, last year this time the lake was about 70-75% full, this year it’s right at about 99% and monsoon season is starting soon. We had a wet winter that really filled up a lot of the reservoirs

    letting in water around motor

    this would be my first guess as well. bellows need attention, and before it gets any worse..... if you have a leak now, you are a bilge pump failure away from a VERY bad day

    Mercrusier MC 1 outdrive

    my boat is same vintage as OP, with the Merc 120 setup. As soon as I find a donor boat close by with the same/similar setup, Im gonna snag it up for spares..... things arent getting any easier to find, shipping isnt getting any faster, and a "simple" failure on this old equipment can be season...

    Out on the Lake Pictures

    Just a quick couple of Roosevelt Lake in central Arizona. Would have more, but my last trip got cut too short for any recreational activities.......

    Where can I find the oil filter?

    i cant help but think we are being trolled here. Knows enough to suck the oil out, but cannot find the oil filter on one of the most popular types of I/O out there. When given instructions on where it is, attempts to remove the exhaust manifold to access the filter..... last post cinches it...

    Where can I find the oil filter?

    if it were mine, and the filter were hidden like that, I would be installing a remote filter mount..... Cry once installing it, and never again.....

    Where can I find the oil filter?

    same location as every Chevrolet based V-6 or V-8 used on boats. as Danforth said, its on the left side of the block at the oil pan rail. UNDER your left side exhaust manifold. You will find your starter in the same spot on the other side of the block. Depending on the design of your stringers...

    Thrust washer…..

    When changing between props and prop brands is it usually necessary to change/replace the thrust washer, or are the props made to work with the “stock” washer unless otherwise noted? Last outing we spun the prop, leaving some wear on the thrust washer. Now I’m slightly gunshy about the setup...

    Black flakes

    the exhaust isnt..... right near the exhaust port in the head will still get hot enough to burn off the paint. Check the underside of your manifolds, and I bet you find the source

    Power Boat sinks in Michigan

    not gonna get into a **** measuring contest, but if things go sideways, I WILL be talking in an elevated tone of voice (AKA YELLING) where things are, to remind those who didnt pay attention before the brown stuff hit the fan..... I dont have time in an emergency to have a long polite...

    How did this happen?

    cant speak intelligently about how it happened, but to get it off, you may just have to back a bit deeper in the water. As long as the boat still floats, use that to your advantage. If there is a "steeper" boat ramp in the area, that would help as well getting more weight off the trailer. A...

    Power Boat sinks in Michigan

    the vid here kind of irritates me...... the person on the camera was too damn busy trying to get their social media hits, and being a monday morning quarterback to actually help. Not looking for someone to throw them a dockline, nor anything else remotely helpful, just sittin there filming it...
