    Why is it still getting hot

    These infrared guns are helpful in diagnosing temperature issues. Aim it at your thermostat housing to confirm it's operating at the rated temperature (140-160F). Aim it at the top of the exhaust elbows to confirm you're getting good flow through each (temps no greater than 120F and fairly...

    Advice sought on tackling prop shaft seal on VP Duo Prop

    Your drive is fine after running three hours with milky oil, assuming you use Volvo oil which has additives that maintain lubrication with some water present. In addition to the above comments, you need to inspect the shaft under the seal for seal wear and grooves. I recently replaced both of...

    Why is it still getting hot

    Welcome. You need to rephrase your question with some sentences. I can't understand your issue with no punctuation.

    SX-M Lower Gear Housing

    You may want to consider getting a remanufactured drive and returning yours back for some core value. I've had good luck with boatwrench.com. The engine question determines the drive ratio. You'll need to get a drive with the same ratio.

    OMC Cobra EFI 5.0L stopped and won’t start again

    When I want to do a quick check for spark, I just pull a spark plug wire, insert a phillips screwdriver into the wire end, hold it near the engine block (1/8"), crank the engine and see if there is a spark between the screw driver shaft and the engine block. Make sure you are only holding the...

    Trailer repair installed wrong disc actuator on 2 axle drum trailer

    Call Dexter and ask them. The master cylinder piston size is likely different between drum and disc actuators. So the actuator will either run out of travel or won’t generate enough pressure. You could just swap the actuators.

    I spray mine with T9 Boeshield, more for corrosion prevention that lubrication.

    Solar Power Installation . . .

    Maybe a wire pulling snake would work better also.

    Solar Power Installation . . .

    I would suggest a Victron DC DC charger. You don't need 60A and they are smaller and less expensive. I have this on my 30 foot boat. The Orion Smart version can be configured and controlled with you phone via app and Bluetooth.

    Reinstall SX M/ What O Rings/gaskets needed?

    Yes, where you drain the oil from. There is an overflow plug next to the shifter. To fill you pump oil in from the drain plug hole and stop when it comes out the overflow plug hole next to the shifter. Make sure the drive is level. The overflow and drain plug share the same size O-ring. The...

    Reinstall SX M/ What O Rings/gaskets needed?

    Typical seals to replace on the SX-M for reinstall are the drain plug, overflow, and dipstick O-rings and the D-shaped water O-ring. I'm not aware of a kit. If you're chasing water/air leak, check the plastic fitting on the other side of the D-shaped O-ring port to confirm the plastic nipple...

    Grooves on hub spindle

    Had the same issue on my trailer. That grooved area is where the rear seal rides. Research Speedi-sleeve and it will show you how to measure the diameter and what sleeve to buy. Be sure to use a gasket sealant under the sleeve.

    Raw Water System Cap Leaking

    Another way (better) to measure exhaust manifold/riser flow is to measure the temperature with an IR gun after getting fully warmed up and running on plane. They should be 110F to 120F, definitely under 140F. If one or both is hotter you have a flow issue. Others may chime in on what the max...

    Weight distribution on trailer bunks and rollers?

    What brand of trailer is this? Are the roller brackets mounted directly to the trailer frame or on to a large bracket that is shared with the bunks? I ask because my Calkins trailer has a teeter totter system that balances the load between the center rollers and the bunks. Either way, why...

    Source for Ford 5.0 EFI Stbd Exhaust Riser?

    Thanks Lou for the input. Are you implying that non-EFI Ford risers are more plentiful?

    Source for Ford 5.0 EFI Stbd Exhaust Riser?

    Thanks @ChrisinPHX, I didn't see that spendy new one. This shortage is making me wonder if I should consider moving to a GM motor with carb.

    Source for Ford 5.0 EFI Stbd Exhaust Riser?

    Thanks guys. I have a query out to 2040, but haven't heard back. All the hits I get on my internet/ebay search end up being out of stock. I've had two orders refunded. I'm going with what hopefully is a lightly used manifold/riser combo for now. Would it be beneficial to soak the lightly...
