    Neutra Salt System

    If you have two reservoirs then you likely have two solenoids. Its unlikely they would both fail open at the same time, so I would be looking at the switch that controls the solenoid to see if it's stuck closed. I would put a meter on the contacts of the switch and confirm it only has...

    Road King rehab

    Axle components are generally sized by the axle rating, which should match or exceed the trailer GVWR. To check the axle condition, pull the wheel/hub/bearings and check the condition of the axle under the bearings and under the rear seal. The rear seal surface condition needs to be very...

    Good Source for Trailer Axles?

    Thank you! I forgot about Speedi sleeves. That's way easier than the axle replacement, brake line transfer, bleeding, etc. There isn't a Speedi sleeve on there already (see pic of other axle).

    Good Source for Trailer Axles?

    I'm getting water in my bearings due to poor axle surface conditions under the rear seal (see pic). I need a galvanized 2"x3" square 5200 lb axle with a 4" drop. This is for a Calkins trailer. I found that Pacific Trailers can custom build one for $280. Before I pull the trigger with them...

    Erroneous Temp Sensor Reading

    I'm having an issue with my OMC/Volvo engine water temperature sensor reading about 35 deg F too high. I've confirmed nominal temperature at the sensor with an IR gun (150 - 160F once warmed up). I've also confirmed the IR gun is reading accurately via a different temp probe. I've replaced...

    AGM Battery Over-discharge Damage?

    I have a Marine dual use 12V AGM battery that I over-discharged to 8.5V. It's charging back up now. I understand over-discharging a battery can damage it, or reduce it's capacity. After charging it I'll take it to an auto parts store for a load test. If it passes that load test are there any...

    Transom Seal for Shift Cable Housing

    I'm starting to chase down a minor fresh water leak in my bilge. One area I want to investigate is the seal where the shift cable housing exits to the outdrive. I remember the cable housing feeling a little loose through the transom when I did my annual service last fall. I've scoured the BRP...

    Lower Temp Thermostat with Closed Cooling System?

    Should a closed cooling system have a lower temperature thermostat than a raw water system? I ask because my motor is spec'd to a 160degF thermostat with a raw water cooling system. My boat has a closed system with raw water going through the oil cooler, heat exchanger, exhaust manifolds, and...

    Keeping canvas alive?

    The key is keeping it clean, so that the waterproofing works. Mine has a lot of pollen and mildew stains. I plan to clean it in an industrial front load washer at a local laundry mat. Holds eight regular loads worth. Will run with mild soap, then again with mild bleach. You can also scrub it on...

    Reverse Uphill with Disc Surge Brakes

    I just had my drum brakes replaced with disc brakes and just picked the trailer up from the shop today. The forward braking is much better and smoother. Unfortunately, the reverse lockout solenoid doesn't appear to be working and I'll have to take it back. This is with a Titan disc surge...

    Water Inlet Removal from Pivot Housing

    This year I tried to replace the water inlet from the pivot housing on my '95 OMC/Volvo Cobra SX drive as preventative maintenance, but there was a ton of white powdery corrosion holding it in place. I tried to remove as much as I could and tried to drive the inlet out with a block of wood and a...

    SX-M Pivot Housing Removal Question

    I've read here that when replacing the drive bellows, it's easier if you remove the pivot housing. I also know that you don't need to replace the exhaust bellows. Is it possible to leave the exhaust bellows attached when removing and lowering the pivot housing to gain better access to the...

    Help w/ Outdrive Corrosion and Improving Anode Performance

    My '95 OMC Cobra SX (Volvo SX-M) outdrive has many layers of black Trilux 33 anti-fouling paint that is chipping and flaking off due to corrosion. I had installed a new Volvo aluminum anode kit during winterization and it's working fine on the transom mount, but I'm having difficulty getting a...

    1995 Joint Venture Drive Compatible with Volvo Dual Prop Lower End?

    Curiosity question... I have a 1995 OMC SX joint venture outdrive (50FAPHUE) and was wondering if it's possible to install a Volvo dual prop DP lower end. Are the Volvo drives metric threads? I know I need 7/16" nuts to RnR the OMC outdrive, so I assume the entire OMC unit has SAE threads and...

    Helicoil in Transom OK?

    While replacing the anode on the transom of my OMC Cobra outdrive on my signature boat (same as Volvo Penta SX), I managed to strip the threads in the transom for the anode due to corroded threads. I plan to install regular helicoils for both bolt holes using loctite to hold in the helicoils in...

    Outdrive Water Drain Plugged

    I doing my first winterization on my signature boat (50FAPHUE) and once I finally removed the water drain plug on the port side of the outdrive, I found it fully corroded and blocked on the inside. I tried cleaning it out with an awl, but couldn't expose the internal water passage. It appears...

    Spark Plug Wire Source for 1995 Ford 5.0 EFI Motor?

    I'm having a surprisingly difficult time finding a source of spark plug wires for my 1995 Ford 5.0 EFI motor in my Chris Craft 21 Concept (50FAPHUE). I found the thread below citing similar difficulty in finding a set that fits. Can anyone share a good source they've found for these plug...

    Winterizing a Closed Cooling System

    I have recently acquired 1995 Chris Craft 21 Concept with a Ford 5.0 EFI engine (50FAPHUE) with a closed water system. I'm not sure if the closed system was stock or added later. The provided OMC pamphlet manual talks about removing drain plugs on the block and exhaust manifold on both sides of...

    Boat Stop to Bowl Loop Distance

    We recently purchased our first boat, a 1995 Chris Craft Concept 21 with original trailer. I wanted experts' opinions on whether I should move my winch tower to get my bow stop closer to the blow loop. As the attached pictures show, I'm limited in how far I can pull the boat forward by the aft...

    Difficulty Shifting to Neutral with 1995 OMC Cobra SX

    Just purchased my first boat; 1995 Chris Craft Concept 21 with an OMC 5.0 EFI motor with Cobra SX stern drive. Overall in excellent shape. One area I'd like to improve is shifting from FWD to Neutral. When the engine is running the transition is a little stiff. Engine off the transition is...
