    Spark plug gap difference

    For context “In most cases your Iridium Power plugs do not need to be gapped. Even with small variations in the factory set gap the ultra-efficient firing power design will compensate for those small variations. Should you decide to re-gap your Iridium Power plug, use extreme caution as improper...

    Axle sleeve time

    Agree. The difference is the use each is under. A crankshaft is spinning 1000-4000 rpm continuously. Whereas a trailer axle is turning slower for shorter durations. Should last longer but certainly check each year when greasing bearings.

    Tie off anchor?

    I stow the anchor in the center compartment or under the seat stowage. Certainly not left where it can fall out or worse, injure someone

    1998 5.7 srartup

    Might want to take a multimeter next time. You are a high idle but the volt meter is low at 13v. Should be at 14v at that rpm. Either a weak battery or alternator issue. I keep watching the smoke video, that is too much smoke for too long to be valve seals. That looks more like bad piston...

    Grooves on hub spindle

    I just repaired mine last week. Here are some pics. Measure where you need the sleeve to end up. Its easy to go too far. And use a sealer to stop water from coming in underneath it. Axle sleeve

    Please HELP! Am I being overcharged for Presale Inspection, Service, etc 2016 Cobalt R3?

    Its not uncommon for a dealer to mark up the service after outsourcing the work. Pay it and remove it from their property before he puts a mechanics lien on it and sells it for what he is owed. Consider it a lesson learned

    1998 5.7 srartup

    Thats a lot of heavy smoke. I would pass on it if it were me. My 5.7 has 550 hrs and only smokes on seasons first start up When it clears the fogging and even then the smoke is more white. That much oil will foul your plugs and run poorly. Plan on rebuilding it. the first thing I did when I...

    Was it fogged prior to being put away? Or just sitting for a month after normal use?

    Exhaust vlave stem seals will harden faster over time than intake seals, due to the higher heat over time and let oil leak into the cylinders. Blue smoke on start up is the sign of oil in the cyl. I’ve replaced valve springs and stem seals before. Its very doable for diy. Once the locks are...

    How to keep exhaust bellows from coming off

    Try to pre-stretch the bellows before installing. I rigged up a strap on my work bench and used a heat gun to soften the rubber. Heat it until the surface looks wet, and keep stretching until it cant go further. Then let it cool fully stretched so it retains the new length. This will take...

    Open cooling system question

    Interesting. Thank you. I took the hose off when I winterized it but did not notice it then. that makes sense, so the hose doesnt collapse under suction.

    Open cooling system question

    When I squeezed the large hose, it didnt compress much. much like when you check your cars cooling system. Maybe nobody has thought to check theirs, but it just seemed strange if the boat doesnt have a closed cooling system.

    Open cooling system question

    Rinker 1995 Captiva 212 5.7 merc alpha 1 gen 2 had the boat out yesterday for first time this season. After doing full tune up, impeller, new bilge blower, and a dozen misc updates, it really runs out nice. Fires right up hot or cold. my question is this. After cruising the lake and then...

    Axle sleeve time

    The flex line finally arrived from etrailer.com and got installed this morning. I cut the old line in half to see its condition. It looks like the steel core is rusting but the lumen is still open. I got lucky on costs on this project. I found the new marine grade drum brakes on offerup for...
