    97 SeaRay 175 project boat hull weeping question

    sounds like you have/had a leak somewhere, and now have a LOT of waterlogged foam to remove/replace. From your pic above, there appears to be moisture inside the test area where you cut the floor. If there is any wood in the structure, its probably mulch by now. Unfortunately foam also retains...

    What reason causes the engine milky oil?

    milky oil has water in it. Could be coming from any number of sources. Budget could be from a couple of hundred for a cracked/worn out exhaust manifold to thousands of dollars if the block is cracked from a poor/nonexistant winterization and the engine freezing. Owner will need to figure out...

    Lost gearage?

    hey, if it worked out for him, and the boat doesnt end up at the bottom of the lake, more power to him. :D

    Quicksilver 5W30 for all sterndrives

    my guess, is that the change, much like with autos is emissions related. Thinner oils contribute (minutely) to lower emissions due to less parasitic and pumping losses...... they dont care about longevity as long as it makes it past the warranty period, but with the EPA up everyones ass about...

    15W-40 oil is it multi purpose?

    the 15w-40 "diesel" oil is good in many things. I use it in the boat, and also in my motorcycle with a wet clutch. It has the zinc in there that many of the old engines need, and no excess friction modifiers to mess with wet clutches.

    Serial number

    Yep, you have to be cognizant of what "type" of flare is used, there is 37 degree (AN/JIC) 45 degree (automotive) and of course the metric bubble flare. Using a single flare where a double flare was used for is a recipe for leaks, even if the angle is correct, as the flared section will be...

    Starter starts something spinning in the back of engine only, nothing in the front.

    PMGR is permanent magnet gear reduction

    Starter starts something spinning in the back of engine only, nothing in the front.

    exactly. check the simple stuff first before pulling engine out. Wouldnt be the first starter that failed and the bendix gear failed to extend, or partially extend making one hell of a racket at the back of the motor

    rebuilt 3.0

    Ill second the Rotella, or other "diesel" oils in 15W40. Not only do they have all the vitamins and minerals that the older motors need, they are relatively cheap to boot.

    Replacing bunks with boat on trailer (too far to get to lift or splash)

    ok, boat and trailer have been out of the water since at least 2013, and the bunks are shot. Since I live about 40 miles from the nearest water to splash the boat (finishing rebuild), I would like to replace the rotten bunks with new wood before towing a longer distance. (the wood is REALLY bad...

    Serial number

    problem is, he is in Australia, so the brake line may be a 10mm bubble flared type locally. This is why I mentioned reusing the originals (if not rounded/stripped) and reflaring with double flare.

    Serial number

    likely the steel brake line has flares on the end of it that hold the fittings in place and seal the line. If your old line has usable fittings they could conceivably be re-used if you have someone who can redo the double flare, otherwise double flaring tools are readily available on eBay or...

    Bearing Hub won't slide on

    just a little bit of galling there that needs to be cleaned up. 5 minutes with a file, and you will be back in business. Dont go nuts on it, just a couple of strokes with a file, test fit, rinse and repeat until the hub slides on nicely. When the bearing failed, it caught on the spindle, and...

    Furst boat and first restoration project, have some questions.

    impellers are a maintenance item, generally regarded as once a year/every second year service items. nothing will ruin your day (and motor) faster than an impeller going tits up at an inopportune time. They are easy to change, so not really worth NOT doing.

    MerCruiser throttle cable

    Not having any luck finding the type throttle cable I need. Goes on a 1980 120 MerCruiser 4 banger. Serial number and carb end of cable are in the pics. Manuals have been no help, same with exploded diagrams… Anyone got any ideas here????

    Bottom up restoration! MY FIRST BOAT

    depending on the size of the boat, 2 gallons should be enough. Yours looks on the small size, so it shouldnt be a problem. There is the FAQ thread up the top that has quite a few rebuild threads in it, along with all the info you should need. There are others here that know that area better than...

    Bottom up restoration! MY FIRST BOAT

    first one I did (before joining here, and learning better) I used the cans. they will work, but are a pain in the ass. Pour in 2 part foam works MUCH better, and in the long run is actually cheaper. Those cans add up fast
