    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.

    MEFI 3 diacom capabilities

    Hi, will diacom allow me to check for spark on a MEFI 3 motor? The issue im chasing is no/intermittent spark while cranking. Its a late 90s 350 mpi with mefi3 and thunderbolt 5. The dizzy sensor is original but i'd like to check that the ecm is firing the coil alright before chucking parts at...

    Lowrance hds. The garmin has a built in integrator, so an FDM is not needed with that.

    Gateway not storing fuel used

    Sorry, forgot to mention my unit is a lowrance HDS 12. no smartcraft gauges. All I have is the hds, the gateway, and the motorguide on the network. I tried all kinds of settings, and loaded the newest update, but the fuel level still shows 0. I selected the center tank source as the mercury...

    Gateway not storing fuel used

    fuel data manager. formerly known as the ep-85. Yes, I tried entering 100 liters for example, and the fuel remaining shows 0 still. To be clear, I want an electronic module to calculate the amount of fuel used based on the fuel flow data from the ecm, which in turn is based on the amount of fuel...

    Gateway not storing fuel used

    Hello, I decided to add an nmea 2000 gateway to my motor (115 optimax). The lowrance now displays fuel flow rate, and all kinds of other engine stuff, but the fuel remaining always shows 0. I tried hitting refuel to no avail, fuel remaining is still stuck at 0. There is a data field for fuel...
