    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"?

    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

    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?

    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

    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

    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...

    Random alarm 5.7L carb'd Bravo 2

    Random alarm - sometimes short chirps, sometimes solid for a few seconds. Only when in gear and at operating temp. The only patterns I noticed are that it often occurs just after I increase throttle. Also seems to occur more around 13-20 kts, and rarely above 23 kts (did not note the RPMs at...

    Help with 5.7L front motor mount bracket location.

    I just finished rebuilding my stringers and transom. Reinstalled my bell housing and inner transom plate. Looking for advice on getting the location for the front mount brackets. They are "L", or angle brackets, if it matters. According to a diagram I found, the distance from rear-to-front...

    Raw water hose to impeller part#

    Mercruiser 5.7L serial# 0M009325 Bravo 2 serial# 0L455278 Is there a part number for the raw water hose that goes from the bell housing to the impeller? I believe it's 1-1/4" ID. Or, can I just use a section of bulk hose? If so, any suggestions?

    Painting over new poly laminate - leave tacky or let cure?

    Just finished glassing in new stringers, and will probably add an extra layer of 1708 inside the entire bilge. I plan to paint the bilge, probably with Rustoleum enamel. That said, should I leave the last laminate tacky, or should I let it cure? And what type of prep should I do with either...

    Electric fuel pump for carb'd 5.7L

    I found a private seller with a pump - model # 861155-2. I could not find this model online, but I did see model # 861155A3 and "replacement for 861155A3". It looks like A3 is an updated version. If so, does anybody know what the update is, and if the older versions are okay to use? My serial #...

    Friscoboater’s Searay resto - drainplug Q

    I’m trying to do what Friscoboater did on his Searay - make an oversized drainplug cutout and fill it with PB so water never has a chance to contact the wood. He placed a section of PVC against the hole and PB’d around it. I’m assuming he did this because it’s easier than drilling through the...

    Fitting outdrive to new transom

    Hello all, I asked about this in a different forum but will try here as well. I have a 1977 Skipjack that needs a new transom. I’m doing this myself with no experience, and with a lot of help from this site and the people that post here. Old one is removed and new one is cut out and I’m...

    Storing resin in other containers

    Hello all. I just bought a 5 gal bucket of poly resin. I’d like to transfer some of it to a smaller container for easier handling. Is it ok to store in a new paint can? I also have an old empty resin can that I can clean out. Any issues with either of these? How do you guys deal with large...

    New transom 1977 skipjack 24’ open

    Had some rot issues so I chiseled out my transom, did some grinding, and now I’m getting ready to glass some wood back in. Never done anything like this before so I’m here to ask the experts some questions. Sorry if the photos are bad. I had a weird half sun/half shade thing going so...

    Battery cable gauge

    I’ve read that the cable gauge should be determined by the length. But if you have multiple runs of different lengths is ok to have different gauges? For example, let’s say the run from my battery to the selector switch is 6 feet so I use 1 gauge. Then the run from the switch to starter is 3...

    Recommend me a rust converter

    Looking for a rust converter that won’t break the bank. I don’t put much trust in Amazon reviews so I’d like to hear from real experience. This is for a Mercruiser 5.7 if it matters. I guess i could also use recommendations on a primer and paint. Pics below, because everyone likes pics.

    I'm in the process of removing my Mercruiser 5.7 sterndrive to do a hull restoration and have a couple questions. Are the circled bolts in the pic the rear motor mounts? Also, do I have to remove the steering control valve before I pull the engine?

    Bravo 2 outdrive removal - stuck

    Trying to remove my bravo outdrive. I removed the the trim cylinders and the 6 nuts. Put a block of wood on top and pulled up on the outdrive but it won't break free. Sprayed some wd40 around the studs and between the mating surfaces but it still won't budge. Any other tips or tricks to this? I...
