    Vinyl ester filler over epoxy and gelcoat questoin

    Hi, two unrelated questions here for two different seadoos First question is can I use vinyl ester filler over an epoxy fiberglass repair? I have a bunch of the 3M marine filler and I really like how it cures fast and I can sand it and throw another layer on in 20 minutes or so. Epoxy with...

    axius TVM issues

    If its a wire harness damaged by saltwater, then I have had good luck with just repinning all of the connectors to get things working again. You can imagine all the stuff I found in those plugs... Main concern is if there is a defective TVM, that would be the biggest money issue. The...

    Mercruiser 6.2 chirping noise

    Chirping still there when the engine is running with no belt? Is the engine alignment ok? If yes, then pull the oil filter and look for metal.

    axius TVM issues

    Hello everyone Looking for my next project boat, I came across a very nice 2009 searay 310. I might go look at it in person. Keep in mind, this is a PROJECT boat. It didn't sink or crash, but does have a TVM FAULT NONCRITICAL and TVMDRIVEFAILURE error. For those that are familiar with axius...

    Marine grease for gimball bearing

    most marine greases are calcium sulfonate. As long as you use the same type of grease and don't mix them, you should be ok.

    1991 Rinker seems like it runs out of fuel.

    I think you might need to try changing your plugs and distributor cap and rotor. Probably needs to be done anyways.

    2 Mercruiser 5L EFI with all 16 Cylinders of 175 psi or more??

    As long as they are consistent they are good. I once had a motor that would consistently kick out 210 psi on all 8 cylinders. I use my gauge a lot, and I know it shows the correct numbers, I even tried a fellow mechanic's snap on gauge, also showed the same. Never could figure out why the heck...

    yamaha fourstroke crank bearings

    Just to be clear... The cams spun freely when the head was removed, and after checking with a straightedge, there was NO warpage - nada. zero. It did have some mild corrosion, which my machinist brought to my attention as being a possible problem that could cause the head gasket to blow later...

    yamaha fourstroke crank bearings

    The guy that will be doing it for me welds aircraft engine cases, very well respected and definitely knows what he is doing. Obviously it will get preheating and heat treatment of sorts.

    yamaha fourstroke crank bearings

    Why would it be warped? I checked with a straightedge and its fine. It needs to be decked after welding because the coolant passages in the head will be welded so the beads will need to be cut flush. Just to be clear, it is the water passages that are corroded around the cylinders and the...

    yamaha fourstroke crank bearings

    Yes, I did. I talked to my machinist and basically he said the whole coloured bearings thing is a load of baloney upsell, the difference in sizes is so small it doesn't really matter. So I went ahead and got a set of king mb5442si bearings, and what do you know, the fit perfect. Clearance was...

    4.3 Vortec Harmonic Balancers...

    I'm pretty sure only the crank is balanced on those motors. Having the crank, balancer, flywheel pistons, and rods all balanced together is really only for the high end motors. If the cranks look the same, get a new marine balancer and throw it together. I wouldn't use the old balancers, 4.3s...

    Bravo 3 Engine Alignment

    Probably some engine mounts sagging with age. Check the front and rear mounts, and if they check out, i'd go up a little on the front.

    MEFI 3 diacom capabilities

    Engine sorted. Some smart fellow put iridium plugs with a washer seat on a motor with a thunderbolt ignition and taper seat plug holes. Also those plugs were super old. I was told they were changed recently, but after changing them anyways the motor lights up nicely.
