    Overheating 502

    Update: Tried to disassemble the rubber boots on the SB side of SB motor today, didn't take too long to realize my logic of disassembling from the manifold risers back to the y boot wasn't going to work without pulling the motor as the bolts that hold the risers in place are much longer than...

    Overheating 502

    Tstat opened up good at 175 and closed at 158. I assume that means that's not the issue.

    Short video and pic of T Stat Is it a bad idea to run with TStat removed to see if it still overheats?

    Overheating 502

    I have videos but apparently they are too large a file. Winter on a trailer in Michigan. I am very confident I winterized the block and manifolds adequately by pulling blue plugs and inserting wire up into it so all water would drain out before reinstalling the blue plugs.

    Overheating 502

    2000 502 Mag MPI Bravo 3 drives with captain call exhaust. I messed up and didn't notice that I failed to reconnect the hose from the I/O lake water intake hose to the impeller last fall. Launched a few days ago and since it wasn't getting any water I smoked the impeller. Since it was bone dry...

    How to get Navionics on a large screen at the Helm

    Bought a 2000 Formula boat that comes with an old Ray Marine plotter that needs to be replaced. I think the Navionics phone app is amazing in detail and accuracy. I suspect I could buy a slightly used tablet and somehow mount it where the Ray Marine unit is now. I would do this instead of...

    Kohler generator cylinders keep hydro locking

    I couldn’t find a generator section so admin please move if needed. After two separate trips I have gone to start my genny only to find its cylinders flooded in water(luckily fresh water). I removed plugs, cranked over until water gone and got it running again. The first time this happed I...

    Solenoid location

    New to me 2000 Formula 400 SS with twin Mag MPI 502 Port engine always starts but struggles to turn over. At first I thought it might be the battery but I have ruled that out by removing them and bench testing at auto store and using the emergency crossover switch that uses both starter...

    V Drive trans oil analysis 1999 380 DA

    Where all 380 DA Sea Ray 1999 V drives made by ZF? Trying to figure out my worst case scenario if I have to rebuild or replace the V drives, but neither I or the seller know what make and model they are.

    V Drive trans oil analysis 1999 380 DA

    The boat I am interested in had a prior buyer back out because the trans oil analysis says something about metal. I don't know exactly what it says, we are trying to get a copy from the survey. I expected to find a lot of posts about this but I can't find anything. What is problematic and what...

    Canvass issue

    I’m wondering if anybody has successfully been able to cost effectively restore the underside of canvass that has what I assume is a factory vinyl coating that is peeling off. Mine is from a 1998 SeaRay. I was thinking of systematically peeling all of it off and applying with a paint roller...

    1998 SeaRay 290 DA Norcold DE-351D Trying to determine if my dead fridge issue is as simple as the thermostat control located inside the fridge. I think I need to close 3 circuits: The Thermistor The On/Off switch The temp dial Thermistor is easy, other 2 are my concern. Which combination...

    Exhaust manifold not draining when probed with coat hanger?

    1999 Sea Ray 290 DA with twin 5.7 freshwater cooled blocks and manifolds. Tried to winterize today but starboard side exhaust manifold on starboard engine didn't drain any water when I pulled the blue plug out. I am perplexed as I have done this many times with various engines and always had...
