    Rotella ELC coolant in Mercruiser?

    I don't have a local source for Mercury/Quicksilver coolant, and I don't like paying the high shipping costs (I'm a cheapskate). West Marine has Shell Rotella ELC concentrate for $35 a gallon. With a 15% off sale and after diluting, it's about $15 a gallon. My service manual says to use an...

    Ordering parts from "MMI Marine" or "Steveston Marine"?

    Yeah, I guess there's no specificity to o-rings in this application. I accidentally broke the o-ring, which I might even just reinstall with the break in the 6 o'clock position.

    Ordering parts from "MMI Marine" or "Steveston Marine"?

    Has anyone ordered stuff from either of these sites? Need an o-ring for my Maxwell windlass HRCFF6 (part# sp0726). These are the only sites that seem to have it in stock...

    Antiseize on sparkplug threads

    Not familiar with this product so I looked it up - labeled as "form-a-gasket". Is this the product you are referring to? Again, I'm not familiar with this but I would think that any type of gasket material could get stuck on the threads of the head and/or pieces could fall into the combustion...

    Antiseize on sparkplug threads

    I've read that antiseize can cause galvanic corrosion in a saltwater environment. Since sparkplugs are not in contact with the saltwater, is it ok to use antiseize on the threads? If not, what would be another options?

    hmm... I can blow through both on the new unit. I think I'll send it back.

    Fuel pump for 6hp 6904E

    Hard to start, and would not stay running. Never touched an outboard before this, but I decided to open the pump to see if there was anything obvious to be fixed. Springs started trying to pop out so I tried to put it back together, but not sure if I got it right so I ordered a cheap pump to...

    Fuel pump for 6hp 6904E

    Hey folks, I purchased a fuel pump off Amazon that is supposed to be a replacement for the OEM part# 388685. But it looks different than the one that's currently installed (not sure if OEM or aftermarket). The new one is taller/thicker and the fuel line bibs are oriented differently. It looks...

    Shim material for swim step bracket

    Thanks everyone, but this is the best suggestion - I tend to overthink things and make them more complicated than I need to. Already had 5200, so I marked, drilled, checked fit, slathered, and bolted up.

    Shim material for swim step bracket

    Or, maybe I could shim all 4 brackets, tighten all bolts down the same amount, and the brackets that started with a gap will "squish" a little less than the ones that started flush?

    Shim material for swim step bracket

    Today I hung the swimstep up to my transom. Below are pics of the transom/brackets gaps, while pushing the unit by hand. Do I even need to shim this?

    Shim material for swim step bracket

    Thanks all. I think I have some scrap starboard laying around. I guess I could sand it down to thickness.

    Shim material for swim step bracket

    Hello all. I picked up a used swim step for my 1977 Skipjack (it came off another skipjack). When I bolt the brackets to the swimstep, they don't all lay flush against my transom (about 2 or 3 mm gap). I tried switching the brackets to different positions, but still not all flush. I don't want...

    Manifold/riser condition

    Thanks everyone. I already put it back together (with new oem gasket). Will probably continue to check every 2-3 years, and dress with a flat file.

    Manifold/riser condition

    I have a 5.7 carb'd Merc, serial# 0M009325 that the previous owner claimed was freshwater only. Did not know the age, or how many hours on it. I've run it for 4 seasons in saltwater, and wanted to know your opinions on the risers and manifolds - they look almost new to me, but I don't know...

    SternPad, SternSaver, Sternmate?

    I made my own out of a scrap piece of starboard glued to my transom with 5200. There is a "treatment" process to get the 5200 to stick to the starboard - light sanding and a quick hit with a flame, if I remember correctly.

    Random alarm 5.7L carb'd Bravo 2

    On ear muffs, I wiggled wires but could not get the alarm to sound. I unplugged the ICM connectors one at a time - engine stalled when the 2 smaller connectors were unplugged. Then I noticed the gear lube monitor was just below the "add" line 🤦‍♂️ so I topped it off. On the water I heared the...

    Random alarm 5.7L carb'd Bravo 2

    Thanks guys. I'll wiggle around with these on my driveway and see if I can get the alarm to sound. Any harm in unplugging any of these while running?
